Robert N. Fried - CEO & Director
Thanks, Heather and good afternoon to all and thanks for joining us on our investor call. The second quarter of 2022 marked an important period of organizational improvement as we adapted to this changing market dynamic and to -- and placing an emphasis on fiscal responsibility, on efficiency and on profitability.
The quality e-commerce business continued to grow, 10% sequentially, and 13% annually. The overall net sales declined a bit however year-over-year primarily due to timing of orders from our partners in Watson, Hong Kong. We believe this timing will be made up in upcoming quarters.
As I mentioned our core ecommerce channels delivering consistent growth and becoming increasingly efficient. Amazon is our fastest growing channel within e-commerce. Despite a challenging macroeconomic backdrop, Tru Niagen has been delivering very strong results there.
As an example, we are very proud to have reached the status of #1 best selling vitamin B3 supplement. This momentum, also supported by nearly double the number of subscribers since the beginning of last year, has enabled us to reduce spending in the short-term by focusing on campaigns that drive the highest conversion.
As you heard last quarter, we launched a new TV campaign for Tru Niagen in late March. We and Walmart were very encouraged by the significant increases in sell-through once our campaign aired. But this improvement came a bit late to impact their spring shelf set plans.
Tru Niagen will continue to be carried, but in fewer stores going forward with the focus on the better performing stores and on our introductory 100 milligrams SKU. We established the TV advertising works well to drive awareness for Tru Niagen, but it is an expensive channel, particularly the linear television channel.
And this is a challenging macroeconomic environment. So we have paused this campaign to focus on our core e-commerce channel, which delivers consistent growth with measurable return on advertising spend and we are already seeing efficiencies in the third quarter.
We see this difficult market as an opportunity to improve our operations. Our expectation is that we will approach breakeven in the third quarter and deliver positive adjusted EBITDA or cash EBITDA in the fourth quarter of this year.
At the same time, we know that the addressable market for our ingredient Niagen, and our brand Tru Niagen remains very strong. This is supported by the science when numerous preclinical studies published this quarter once again support the efficacy of our novel ingredients nicotinamide riboside. These include studies investigating the effect of Niagen and cardiomyopathy, on neuropathy, on inflammation, and on myogenesis.
In addition, and importantly, preliminary findings from a study supported by the Gates Foundation, and conducted by our Chief Scientific Adviser, Dr. Charles Brenner, were presented at the face of NAD+ Metabolism and Signaling Conference this past June. The study performed in an animal model showed that moms supplemented with Niagen, bore offspring with improved body composition and brain development significantly outperforming NMN.
We look forward to sharing more once the results are peer reviewed, and published. And as the science supports the long-term prospects for Tru Niagen and Niagen so does our continued innovation in the NAD precursor space, which we will share in the future updates.
We also made significant strides in our China strategy this quarter, a large and growing market for NAD supplements. As many of you know, we have a partnership with Sinopharm Xingsha, a large state owned healthcare group in China. As consumers already understand the benefits of elevating NAD in China, we can differentiate Tru Niagen as the most trusted and science based brand with a trusted local marketing partner like Sinopharm. While we have been in discussions with Sinopharm since late last year, we solidified our relationship in June with the cross-border agreement.
This now enables us to progress more quickly toward commercialization. We continue to be impressed with their deep knowledge of the local market, as well as commitment to our brand and we look forward to them taking over the management of the cross-border operations in the coming months.
We also signed an agreement to establish a joint venture in China to pursue Blue Hat approval for in-country sales for Tru Niagen. This will open an even larger addressable market to accelerate growth over time.
Another strategic market for Tru Niagen is South Korea, where we recently signed a definitive agreement with Juvenis, our healthcare marketing partner in the country whose focus is on cosmetics and dietary supplements.
Lastly, in the broader Asia Pacific market, our new partnership with H&H is progressing quite nicely. They recently launched their first exclusive product with Niagen, the Swiss Beauty Activator in Australia, and they have plans to launch this as well as other products targeted at a unique benefit areas in China cross-border as well as other markets. As a reminder, the Swiss brand is the leading brands on China cross-border platforms and we remain optimistic about the prospects with H&H.
We are very excited to enter a new period of corporate development. As we continue to grow the Tru Niagen brand broadening our revenue base geographically through partnerships and our strong recurring revenue base of well informed users who are actively seeking the best science-based supplement to aid in improving their overall health and well being. Part of this transition from being a growing startup to $70 million global revenue run rate for Tru Niagen has been a stepwise series of leadership changes designed to assist ChromaDex in its next phase of corporate lifecycle development. This includes meaningful changes to our Board of Directors as well as our executive leadership team.
In April, we added 2 outstanding female executives Ann Cohen and Kristin Patrick to our Board of Directors. Ann is a financial expert, and our new Chair of our Audit Committee, and Kristin, the new Chair of our Non-Gov Committee brings extensive marketing expertise most recently at Claire's and previously at Pepsi.
And just this week, we welcome Hamed Shahbazi, CEO of Well Health. Hamed is a successful healthcare Internet entrepreneur, whose company is focused on consolidating and modernizing primary healthcare facilities and practices in Canada. These 3 great executives are injecting new perspectives and energy into our Board. And we are very grateful that they have decided to join us.
And our executive team has also undergone some changes. As many of you know, our Co-Founder, Frank Jaksch, has stepped away from his executive duties to pursue a new entrepreneurial venture in a complementary space synthetic biology, but he will remain as Chairman of our Board.
We also have a new Head of the Legal Department, Heather Van Blarcom, who is joining us on this call today. Hi, Heather. Heather has been Assistant General Counsel of ChromaDex for almost 9 years. She is an extremely talented executive, who has extensive knowledge of ChromaDex and over 2 decades of experience in the industry. I'm quite confident she will manage our legal affairs, our litigation and our overall legal expense quite prudently.
And finally, Kevin Farr is stepping down as Chief Financial Officer. ChromaDex has long been respected in the ingredient and dietary supplement industries as one of the most respected scientific and regulatory affairs companies. Under Kevin's supervision, our finance and operations have become equally and universally respected. We thank him for sharing his years of experience as CFO at Mattel and experience at Price Waterhouse prior to that and for helping us to proudly become the professional organization that we are today.
We now look forward to working with Brianna Gerber who was recently promoted to Interim CFO. Brianna has over 20 years of diverse experiences in investment management and finance at the Capital Group, at Mattel and of course, right here at ChromaDex. Brianna will be and he is a key leader in our efforts to continue to improve the organization as we adapt to this changing market dynamic and to place an emphasis on fiscal responsibility, on efficiency and on profitability. Over the last 4 years, I have been quite impressed by her leadership, a broad business acumen and her passion to constantly deliver positive results. I'm very excited to be working with her.
In summary, I'm quite bullish on what is taking place at ChromaDex on the internal changes. And the key pillars we have put in place for our China's strategy and globally and for our upcoming scientific developments.
I would now like to return the call to Kevin and Brianna who will run through the quarter's financials and then on to Q&A and closing remarks. Kevin, Brianna.
Kevin M. Farr - CFO, Principal Financial & Accounting Officer
Thank you, Rob. Good afternoon. It is a pleasure to speak to you today. It has been an honor to be CFO at ChromaDex for the past 5 years. Since our pivot 5 years ago, we have grown Tru Niagen into a global $60 million brand with a global footprint and diversified channel strategy.
Expanded gross margins from around 48% to over 60% and achieved cash flow breakeven in our underlying business, excluding total legal expense, with a focus on achieving this including total legal expense in the fourth quarter of this year.
I want to announce my transition from CFO to consultant, providing services over the next few months to ensure a smooth transition. I also want to congratulate Brianna Gerber, Head of Finance and Investor Relations on the promotion to interim Chief Financial Officer.
As many of you know, Brianna has been my most trusted finance partner for the better part of a decade, as she moved with me from Mattel to join ChromaDex. Over the last 4 years, her role has evolved as she assumed more responsibilities in almost all aspects of the business, which has prepared her to ascend to the CFO role.
Over the last year, we have made significant progress on building a global brand, optimizing our marketing messages, and testing targeted advertising campaigns, focused on specific benefits of Tru Niagen since aging means different things to different people.
We believe these activities provide a strong foundation that will accelerate our revenue growth rate, as well as improve our profitability over time. Finally, I'm also proud of the strong teams that we built across the company in just a short few years.
With that, I will hand it over to Brianna who will comment on the quarter's results, as well as put into context or strategies going forward before we dive into the details. Brianna?
Brianna Gerber - VP of Finance & IR
Thank you, Kevin. Let me first say that I'm grateful for the opportunity to serve as interim CFO on behalf of our ChromaDex shareholders. We have a novel ingredient that can unlock a very large addressable market of consumers, who want to address a root cause of aging and I believe we have the right team in place to capture this opportunity globally.
As interim CFO, my immediate objective is to look at all areas of our cost structure, with an emphasis on becoming a leaner and more focused organization beginning in the third quarter. We recognize this attention to operational efficiency is critical in the current economic environment.
We have already adjusted immediate levers such as media spend in July, and reduced R&D spend on projects without a clear ROI for large commercial opportunity. I'm encouraged by the executive team's commitment to this important initiative and look forward to leading the company through this transition.
In the past, Kevin has discussed adjusted EBITDA, including total legal expense, as a proxy for cash flow prior to working capital investments. We expect to approach breakeven in the third quarter and our targeting cash flow breakeven are better on this basis in the fourth quarter of 2022.
With that, let's turn to the second quarter financials. ChromaDex reported total net sales of $16.7 million down 5% year-over-year, and a strong gross margin of 60%. Importantly, our e-commerce business continued to grow with 13% growth year-over-year, and 10% growth sequentially in the second quarter. As a reminder, the prior year period included Amazon Prime Day, which falls in the third quarter this year, so underlying sales were even stronger.
Overall sales were down due to 2 primary drivers. First, the timing impact of sale to Watson due to COVID-19 and second, the initial shelf stocking to support our Walmart launch in the second quarter of 2021, both of which created challenging prior year comparisons. Adjusting for the Walmart impact alone, our net sales would have been roughly flat year-over-year.
As Rob said, given the current macroeconomic environment, the company has pivoted to spend on distribution channels and marketing campaigns with the highest short-term return on investment and a strong focus on conversion beginning in the second half of 2022.
We are optimizing advertising spend within these channels, targeting consumers who are more likely to convert based on their purchasing patterns and demographic profiles. And we are exploring tools we can leverage to become even more sophisticated in this targeting going forward.
At the same time, we have decided to pause our television campaign, which while effective is a much more expensive marketing approach in the short term. For context, we invested just over $1 million in TV in the second quarter. This TV campaign was originally launched to support brand awareness at Walmart, but we anticipated that our e-commerce channel would also benefit, which it did.
As Kevin noted last quarter, we saw increases in organic searches and new website visitors, growth in new customers on our own site, as well as strong sales trends on Amazon. Well, Walmart was encouraged by the sell through trends immediately following the TV launch, they had already planned to reduce our spring shelf that for Tru Niagen.
As a result, the 300 milligram, 30 count SKU will no longer be carried in stores and the 100 milligram 30 count introductory skill will be sold in fewer stores. We view this as a healthy reset for the brand to focus on the better performing stores.
Beyond Walmart, we recognize that a brand like ours requires continuous consumer engagement and education. This extends to our B2B partnerships, where we are increasingly looking to learn from each other and adapt content to their local markets. We recognize that many of these partnerships have been slower to ramp than we anticipated.
Consistent with our emphasis on efficient spend, we are focused on maximizing sales with our existing partners as we add important new strategic partners like Sinopharm to optimize our omni-channel global distribution strategy.
Moving to the P&L details. Total net sales in the second quarter of 2022 were down 5% year-over-year compared to the second quarter of 2021 with a 6% decrease in Tru Niagen, driven by 13% growth in e-commerce offset by a 47% decline in combined Watson's and other B2B sales as previously discussed.
Gross margins decreased by 110 basis points to 60%, compared to 61.1% in the second quarter of 2021. The decline was primarily driven by a loss of scale due to lower net sales, coupled with input cost inflation, and increased headcount in our supply chain to support future growth. We also had a small impact from markdown funds at Walmart, as they optimize their store and SKU mix for Tru Niagen.
We are very proud of the work by our supply chain team to achieve a consistent strong gross margin of 60% in a challenging inflationary environment. Selling and marketing expense as a percentage of net sales increased to 47.9%, compared to 35.2% in the second quarter of 2021.
Our investment in TV advertising was a driver of the increase. But as mentioned, we have paused this top of funnel spending, which will improve the trend in the second half. We are also experiencing higher costs for new customer acquisitions driven by broader industry trends year-over-year.
As reported general and administrative expense was lower by $2 million, primarily due to lower legal expense of $2.4 million partially offset by increased investments in technology and increased staffing in key functional areas to support growth. We expect legal expense to further decline going forward and continue to expect full year 2022 legal expense to be under $7 million.
For the second quarter of 2022, our operating loss was $6.4 million versus $5.6 million in the second quarter of 2021. The net loss attributable to common stockholders for the second quarter of 2022 was $6.4 million or a loss of $0.09 per share, as compared to a net loss of $5.6 million or a loss of $0.08 per share for the second quarter of 2021. Finally, our adjusted EBITDA, including legal expense, was a loss of $4.6 million compared to a loss of $3.5 million in the prior year.
Moving to the balance sheet and cash flow. Our balance sheet remained strong. We ended the quarter with $17.1 million in cash. In the second quarter of 2022, our net cash used in operations was $3.8 million versus $7.9 million use of cash in the second quarter of 2021. The difference year-over-year was primarily driven by lower trade receivables, due to timing of payments from customers, as well as other changes in working capital, including inventory investments and timing of payments to our vendors. As a reminder, the second quarter of both periods includes the payout of a bonus to employees related to prior year company performance.
As it relates to our 2022 full year outlook, as I mentioned, we believe our decision to focus on more efficient channels and make tough decisions related to our cost structure will enable us to be cash flow breakeven or better in the fourth quarter of 2022 and approach this goal in the third quarter.
Our updated net sales outlook is high-single-digit growth. While e-commerce remains strong, the reduction from 15% to 20% previously is primarily driven by lower growth from combined new and existing partners due to continued COVID-19 headwinds internationally, as well as a slower ramp up with new partners.
We expect approximately 60% gross margins, slightly lower selling and marketing expense in absolute dollars year-over-year, approximately $1 million increase in R&D, and approximately $6 million to $7 million decrease in G&A. Relative to our prior outlook, this reflects more conservative investments in marketing, as well as R&D, with the focus on near-term ROI and a reduction in executive headcount and G&A. We have provided details on the key P&L metrics in our earnings press release along with the slide presentation.
In summary, I'm excited for the next chapter of ChromaDex. We have work to do, but I'm confident we can achieve positive adjusted EBITDA. Additionally, we have learned so much about our consumers over the last 5 years, and can build on this foundation going forward.
By segmenting our Tru Niagen and Niagen consumers into different cohort groups, through e-commerce, analytics, as well as insights from our partners, we can orient our marketing content, communications, R&D and business development pipeline to strategically target the market. We look forward to sharing more about how we are optimizing the business to align with this consumer-oriented vision in future calls.
Operator, we are now ready to take questions.
Operator
(Operator Instructions) Your first question is from the line of Brian Nagel with Oppenheimer.
Brian William Nagel - MD & Senior Analyst
Congratulations, Brianna. Kevin, congratulations. So a few questions here, if I could. First off with respect to Walmart, maybe could you size what is happening for us here. So you have the kind of shift in number of stores and I think you said, you are going to (inaudible) Walmart now, it is only 100 milligram product, but you are not going to sell (inaudible) products or maybe if that is the case, and then what extent is this shift to Walmart -- how do we think about the near-term financial implications of data? How big a piece of your reduction and guidance is Walmart?
Then the other question I have on this is, we talked about Walmart, together with a TV advertising, is the pullback in TV advertising somehow tied to this is shifting in Walmart?
Robert N. Fried - CEO & Director
So Brianna, I will answer the second one first. And I will let you answer the first question second.
Brianna Gerber - VP of Finance & IR
Okay.
Robert N. Fried - CEO & Director
Are you there? Okay.
Brianna Gerber - VP of Finance & IR
Yes.
Robert N. Fried - CEO & Director
Sorry, Brian. We are in 2 different locations. So there's this a tad bit of a delay.
So the primary reason for the pullback on the television campaign -- by the way, what we are pulling back on is linear television, we are still going to be streaming television. It is linear television, which is much more expensive of the 2 and much more difficult to measure, and much more top of the funnel, expensive. And that is the primary reason.
We have a nice clean balance sheet, but we burned some cash. We want to stop burning cash, we know that this is not a good time to be burning cash. We have a great product, we have a great revenue base, we have a great operation. The idea here is to be lean and creative and profitable.
And top of the funnel very, very high, most expensive top of the funnel marketing is linear television. So that is the primary reason. But secondarily, yes, there was some impact there if we did get the television ad out and we did see dramatic improvement in the performance across the board of all metrics, not just sales at Walmart, but Google searches traffic to our website sales and other places. I mean, it shows that it was an effective ad. And the media buy was effective as well. But it is very expensive.
And it is something that you have to maintain. It is not like other forms of marketing, like digital media marketing, where you can go in and out and measure real-time performance and return on ad spend and customer acquisition costs and then make short-term adjustments. Television is much more difficult than that.
So because Walmart did want to pull back from approximately 3,800 stores to approximately 2,000 stores, I believe and because we are selling a lower priced product. When you do the math, it just seemed like the return was not going to be there as much. So that is the secondary reason why we decided to pull back on linear television spending for the time being.
So Brianna, I can hand off the first part of the question to you.
Brianna Gerber - VP of Finance & IR
Sure, Brian. It wasn't a big part of our change in the top line outlook. So Walmart was not a big change. For reference, we said that last year's initial shelf stocking with about $1 million. If you look at our net sales that we report, Walmart would be in the other B2B, it was about $1.8 million in Q2 last year, about $1 million this year. So again, Walmart is a key driver of that the bigger driver year-over-year, as we said, though, is Watson. And again Rob commented on the store count reduction for the 100 milligram SKU and then it won't be carried for the 300 milligram.
But the key here is that the stores that they are focused on, this was a bit of an experiment in a wide footprint at Walmart. Now they are refocusing on the stores that are performing better and the SKU that probably hits the price point mark. So we do view it as a healthy reset, and again, not a key piece of the change to our financial outlook.
Brian William Nagel - MD & Senior Analyst
That is very helpful. If I can squeeze in one more, just sure, I guess, just bigger picture from a demand perspective. So you talked about it. I mean, every consumer company I speak with or follow was talking about, to some extent a more challenging macro backdrop, largely brought on by the inflationary pressures on the consumer. So when you look at your business, are you seeing more -- from that standpoint, are you seeing more pressure on kind of attracting that new customer to ChromaDex or you are seeing a higher churn rate with customers that are already using the product?
Robert N. Fried - CEO & Director
Actually, that is an interesting question. I don't know if the answer is unique, but we are seeing sort of an almost an extraordinary increase in [new to breath.] However, we are seeing an increase in churn and one of the reasons why we are seeing -- I mean truly like dramatic increases in the number of new customers coming to the ChromaDex via the e-commerce channels.
But part of the reason is because we did offer this 100 milligram SKU. So it is a much less expensive SKU. But, we all know that the science behind Tru Niagen and I'm sure at this point, you know Brian, and everybody else who is listening knows that the science really does show that 1,000 milligrams is where most of the studies are, have been conducted and show the dramatic, statistically-significant results.
Most of us at ChromaDex take 1,000 milligrams, but that is pretty expensive. So if you take 100 milligrams, we do have research that shows that there is a dose response, you do have an elevation of your NAD levels, but it might not be as easy to notice in your general health or lifestyle. So there is a higher churn rate of those people that buy the lower dose.
So the answer to the question is, yes. No, we are not having headwinds, a new to brand, but yes, we are seeing a higher churn rates.
Brianna Gerber - VP of Finance & IR
And Bob if I could build on that quickly. Brian, just to accentuate that our new and returning customers both grew sequentially in the quarter. So I'd echo and reiterate what Rob said. And back to the outlook question. Our expectation is, even with the lower spend, our e-commerce business grew about 13% in the first half, it should be able to grow at a similar rate albeit slightly lower with the reduction immediate spend in the second half.
So again, that is not what we are experiencing our business, on the e-commerce side. The reduction in outlook is more about slower ramp with new partners, continued international partner headwinds with COVID that we thought by now would be starting to abate.
Operator
Your next question is from the line of Mitch Pinheiro with Sturdivant & Company.
Mitchell Brad Pinheiro - Research Analyst
My congrats to Kevin and Brianna. So, look forward to working with you more closely Brianna and thank you for all your time, Kevin.
I guess, first question. So, listen, we have seen 4 consecutive quarters of slower e-commerce growth, it is grown, but we are just seeing, it is ticking down from as high as 31% growth. There was an obviously an anomaly there back in '21, but it is falling. And meanwhile, it doesn't seem to match the growth of the science and even just the media -- I would say media awareness, but certainly the scientific publications and we are seeing more of that.
Why -- I would have expected it to be a little stronger than 13% growth. I realized Amazon Prime that was -- I appreciate you calling that out. But is this really just something you can kind of turn on with more effective e-commerce marketing advertising and why (inaudible) just mentioned with e-commerce, maybe swelling a little bit in the second half as partly due to the lower TV. So, if TV is not effective, then why would it be driving the second half?
Robert N. Fried - CEO & Director
What was the last thing you just said? If TV's not effective, did you say?
Mitchell Brad Pinheiro - Research Analyst
Yes. I meant if TV's not effective, why would we be expecting having that as negative impact to the second half sales?
Robert N. Fried - CEO & Director
Okay. I don't think we said that -- Brianna, do you mind if I answer that? Brianna?
Brianna Gerber - VP of Finance & IR
Not at all.
Robert N. Fried - CEO & Director
Thank you. So I don't know that we said that TV was not effective. I think in fact, the data that we looked at showed that it was effective. But it's very expensive and you have to sustain the investment in television for quite a while. And it really does cost a significant amount of money. But we did see benefits across the board from that TV campaign of all the metrics that we measure. The other thing I wanted to point out is that the Amazon Prime numbers are -- that week is fairly -- it's a fairly significant week. The numbers can be fairly dramatic. Like in some cases, several times the average that you do in a single day. So it could really dramatically skew the percentage growth in any given quarter.
But in answer to your question, the sales of the e-commerce channel are directly a function of your customer acquisition cost and of your retention. We are seeing very strong reductions in our customer acquisition costs over the last several months, which is very, very encouraging. But partly because we have been selling a lower SKU, and partly because of the economy, we are seeing a slight increase in churn and cancellations. So -- but the good news about that is, that it's something that you can address, but not expensively. There are ways to manage churn and cancellations without having to buy television ads.
So I do believe that the growth rates for the e-commerce channel can and eventually will increase and get back to some of the levels that you've seen in the past. But we've given guidance for the next couple of quarters, where we are expecting to spend significantly less in digital marketing. So we're giving what we consider to be realistic and perhaps conservative projections, where we will still see comparable-type growth, but at a much reduced investment in marketing.
So go ahead Brianna. Did you want to add to that?
Brianna Gerber - VP of Finance & IR
Yes. Just one more point on that. Mitch, we said similar growth to the 13% in the first half, but as Rob said, pretty significant reductions in spend. It's not just TV, we really are focusing on even the digital media and trying to optimize that, some of our campaigns within Amazon, within social search and get more efficient. So we think we can achieve again a similar growth with lower spend, might be a touch lighter, but nothing more than that.
Mitchell Brad Pinheiro - Research Analyst
And you also -- obviously, I would imagine every quarter you are adjusting your digital spend, it seems like to be. I mean, is it a moving target for you as to what is resonating or, I mean, why? Is there something inherent either in the product or in the messaging that needs to -- what needs to be optimized further than what you have been doing?
Robert N. Fried - CEO & Director
Well, that's a very good question. So part of the beauty of digital marketing and e-commerce marketing is that you could really identify specific cohort groups. And different cohort groups respond to slightly different messaging. For example, in our case, generally, it's people looking for a solution toward metabolic aging generally. And so our general customer base tend to be older. They are fairly evenly distributed between men and women, maybe a slight tilt towards women. But it's generally evenly distributed, but they tend to be people who are concerned with the way their body is aging.
But the way the body ages can differ from person-to-person, and indeed, with all the sciences coming out on Tru Niagen we are seeing very, very specific benefits towards some indications -- in certain specific indications, for example, the study that was published last quarter on Parkinson's. For some people, aging is cognitive. For some people, it's energy. For some people, it's sleep. For some people it's muscle, or heart. It varies. So what you can do with digital marketing, though, is you can tailor a message towards a cohort group that is, for example, more specifically interested in cognition, and remembering where their keys are. For some people, aging means I can't find my keys.
So a message that specifically says to them, we might have a solution to that problem, cognition, help the brain, help you get a much higher conversion rate. So while not managed, e-commerce really does have multiple messages. And it's targeting different cohort groups that are responding to those different messages. And then you are finding, what they call, lookalike audiences. Once you find a cohort group that responds to a particular message, you then widen the funnel and target others that are similar to them. And so the optimization process could go on really forever. And where we are at as a business, tens of millions of dollars of sales online, we could do many times that by continuing to optimize and pursue that channel.
Brianna Gerber - VP of Finance & IR
And I'll just compliment the team for their work on Amazon, our landing pages, highlighting some of those benefit areas has really set a great foundation for us, as we have tested and learned and you have to invest to test and now we are dialing that in based on our learning.
Mitchell Brad Pinheiro - Research Analyst
Okay. One more question on your quest to reach cash flow breakeven. Does that carry into 2023? Is -- sort of the run rate that you're achieving in the fourth quarter, you think if 2023 going to be a positive cash flow year for you?
Kevin M. Farr - CFO, Principal Financial & Accounting Officer
Yes, it carries into 2023.

Your next question is from the line of Ram Selvaraju with H.C. Wainwright.
Raghuram Selvaraju - MD of Equity Research & Senior Healthcare Analyst
Just 3 very quick ones. Firstly, I was wondering if you feel at this point that you have already established at which price point you expect you might see meaningful demand destruction. In other words, do you know precisely where and, again, this may be dependent primarily on the SKU, but do you know precisely where the demand inelasticity is? And how can we expect you might be able to take advantage of that from a sales growth perspective as well as margin improvement perspective going forward?
Secondly, I was wondering if you could provide some color on how quickly you anticipate seeing meaningful impact from the Sinopharm collaboration with regard to potential revenue coming from the China region and if this is more something that we should be looking to see -- show up in the numbers next year? And lastly, if you could comment at all on this progress status or current status of your relationship with Nestle Health Sciences?
Robert N. Fried - CEO & Director
Yes, thank you for those 3 questions. So let me go in reverse order. As you know, Ram, and we have discussed in the past, Nestle is a very sophisticated science-based operation, and they are also the #1 dietary supplement company in the world. One of their leading researchers Carles Canto is also one of the leading NAD researchers in the world. In fact, he recently published a study about the combination of NR and NRH, another NAD precursor that -- for which ChromaDex has licensed patents, showing that the combination was actually more effective than just NR alone, but that NR alone is still the most effective way to elevate NAD.
So the relationship with Nestle, it goes quite deep. We speak to them, to their scientists, to their business people and they are very interested in nicotinamide riboside as they have, and have expressed interest in the past and we've shared that. We've had discussions with them about expanding the relationship with them. But we have not arrived at an understanding of what that would look like, they have many brands, we have our own brand. But the Nestle relationship has not yielded other than the $5 million that they paid for the rights has not yielded a tremendous amount of ingredient purchases by Nestle. But I do think that the possibility remains that at some point that, that relationship could get expanded. There is interest on both sides.
With regard to the first question which is price elasticity. That's a very, very good question because what we've observed is our primary -- if I were to say something collective about our customer base, it's that they are very smart, it's a very educated group, it's a very successful group. They have a high average income, extremely high education level. And the #1 reason that people purchase Tru Niagen is because it was recommended to them from a friend. And that friend could be a doctor or an educated friend or nutritionist or an advisor or something like that. So the elasticity with our existing customer base is pretty low. Like we believe we could raise the price and it wouldn't have much of an impact on our existing customer base.
However, what we've learned over the last really 6 months, or even slightly long -- more since the Walmart launch and the launch of our 100 milligram product on Amazon is that there is a much, much bigger and broader market that has much greater elasticity that perhaps is a lower income and a less educated audience group, but also interested in the way their bodies age, that's interested in a lower price point. Further than that, we also have data to suggest that there might even be a much higher cohort group that would be interested in paying significantly more for an even higher dose or a combination product.
So it's not a simple answer. There are different segments of the market that have different levels of elasticity. And of course, our goal is to make nicotinamide riboside available to not just old people but pets as well, because we think it has a dramatic improvement on the body's health, particularly as it ages. So we do think that we could accommodate, with our existing customer base, a slight increase, but there is arguments to be made that there are other cohort groups that would dramatically expand growth in our addressable market if we went much lower like we are seeing as the 100 milligram, but also some evidence that there is a tighter smaller group if we went much higher. I don't remember question #2.

Maybe I can just finish that one off Rob and then Ram can repeat, if that's okay. On the rising inflation, as you know, Ram, (technical difficulty) The last question was about Sinopharm.
Brianna Gerber - VP of Finance & IR
We have a delay. Let us jump to Sinopharm.
Robert N. Fried - CEO & Director
Okay. So, yes, that's -- the second question was about the Sinopharm relationship. We expect Sinopharm to take over complete management of our cross border business in the fall. So we expect them to launch a campaign in connection with them taking over that operation. But I don't expect the numbers to be significant until next year. Okay, does that answer your questions, Ram? Okay, I think Dennis, I think Ram may have -- be on mute.
Brianna Gerber - VP of Finance & IR
I think you answered them Rob, so let's go the next one, please, Dennis. Thanks.

The next question is from the line of Sean McGowan with ROTH Capital.
Sean Patrick McGowan - MD & Senior Research Analyst
I've a couple of them. One -- I'm not sure who would be best to answer this, but the kind of pulling back from the TV spending, will there be other channels that get a boost in spending or is -- or you're just looking targeting a reduction in overall marketing spending?
Robert N. Fried - CEO & Director
I don't expect a boost in spending in any other channel, but I do expect to boost in certain other -- and activity in certain other channels. Probably, one big important source of business for us is the healthcare practitioner market where we sell a version of Tru Niagen, we call it Tru Niagen Pro to physicians, nutritionists, healthcare practitioners in general. And we could see a boost in activity in our marketing activity in that channel. And concurrent with that would perhaps be the sports channels, professional sports teams, college sports teams. And then we might increase our overall, maybe not channel, but marketing activity to the partners that we have.
The e-commerce business is a very solid, strong business that keeps growing steadily. But the B2B business where we supply the ingredients to partners or we supply it to retailers, or distributors, sometimes they could use some support. They don't understand the science quite as well, or they are perhaps less aggressive. So we might support our business partners a bit more in our marketing activities. And of course, all word of mouth, social media influencer-type of activity, we'll be increasing activity there.
Brianna Gerber - VP of Finance & IR
And just emphasizing on that, that doesn't mean spend necessarily. What Rob, I think, is saying is it's allocation of time and resources and really making sure our head of sales, business development, marketing are really aligned and supporting and optimizing our existing partnerships. And when we have new partners coming on board, they are just as excited as we are about the science and the content in their channels.
Sean Patrick McGowan - MD & Senior Research Analyst
That's a good segue, thanks for clarifying. Second question, does the fact that you are able to put up 60% margins with the kind of sales coming in a bit softer, does that suggest that it could have been, and could be in the future, significantly higher than kind of low-60s? Like, are you already seeing positive variances in the supply chain that give you optimism for an even higher level of gross margin when we do see sales growth kind of reaccelerate?
Robert N. Fried - CEO & Director
Brianna, I'll let you answer that.
Brianna Gerber - VP of Finance & IR
Sure. So Sean, scale -- loss of scale year-over-year and sequentially was a piece of it. However, we are seeing the inflationary impacts in our supply chain overhead, rising wages, also hiring to support growth -- future growth and input costs. So what I would say is we feel good about our approximately 60%. That's our full-year outlook. Longer term, yes, I think there's always an opportunity for the gross margins to go up. We look at cost savings programs every year, and ways that we can also make our internal operations more efficient. So I do think that there is an opportunity longer term.
Sean Patrick McGowan - MD & Senior Research Analyst
Okay. And then I just wanted to ask Rob to clarify something I think you said early in the call regarding -- and you touched on it again, the timing of Watson's sales. Are you -- would you suggest that, maybe you'll get that back and then sell them or just that you'll get back to where you would have been anyway? Like, in other words, are those sales lost or could we get them back but at a later point?
Robert N. Fried - CEO & Director
We think we'll get them back this year.
Brianna Gerber - VP of Finance & IR
And Sean, if you look at the third quarter should be higher than the second but more weighted to the fourth, as we have said in the past, because of the timing of their promotional selling period. So shipping to them aligning with their sell through, that's [11-11 and 12-12]. So the third quarter might be more like an average of historical sales with a higher fourth quarter.
Sean Patrick McGowan - MD & Senior Research Analyst
Got it, great. And then last comment is just, Kevin, it was a pleasure working with you for 16 years at Mattel and 5 years at [ChromaDex] and hopefully, our paths will diverge and Brianna, look forward to working closely with you here at ChromaDex.

Your next question is from the line of Jeffrey Cohen with Ladenburg Thalmann.
Destiny Alexandra Hance Buch - Analyst
This is actually Destiny on for Jeff. Congratulations, Brianna. And Kevin, you'll be missed. I guess most of my questions have been answered, which is awesome. I just wanted to get a little more insight on to your commentary around R&D. I heard you say you are going to reduce your spend a bit and focus on projects with a near-term ROI. So I'm wondering if you can maybe elaborate to the extent that you can? And could we expect the launch of something similar to like the immune products that kind of target maybe some of those other demographics that you have been -- that you've discussed as you kind of widen that funnel?
Robert N. Fried - CEO & Director
I don't have an expectation of launching in the near-term and other products like the immune product, which is a formulation product. We do have partners that are launching formulation products like H&H. But I don't expect the Tru Niagen-branded formulation product as a third SKU in the near future.
The comment you made about ROI, I think that was Brianna's comment about R&D, and being selective about our R&D investments. So there's a measurable ROI. I can -- after I make a comment, I'll defer to Brianna to clarify that specific statement. I could just tell you generally about R&D that it's very rare for a dietary supplement company to develop novel ingredients the way we do and to conduct the level of research that we do. We have not only nicotinamide riboside but we have other precursors as well, as I mentioned before, NRH and NAR. And these are important ingredients that we are learning more about and a lot about, and we do not monetize or commercialize in any way right now. And it is important for us to not just own this knowledge and control these molecules, but to turn them into business for our shareholders and we intend to do that.
So I will let Brianna answer the specific question of ROI and R&D investment.
Brianna Gerber - VP of Finance & IR
Sure, I was actually, Rob, piggybacking on the NAD precursor development. As you know, Destiny, we've built a very large portfolio around NR and other NAD precursors. So we have also said not just in short-term ROI, but large commercial opportunity and things that are strategic. So we're just prioritizing within that, we have been moving everything forward, as is important, but we are just pulling back on some and prioritizing others as one example. And then also within our CERT program, we look at the projects that we might be co-funding, again, most of these were just supplying the ingredients. But if there are any that were co-funding, that there is a market opportunity for those.

Your next question is from the line of Jeff Van Sinderen with B. Riley.
Jeffrey Wallin Van Sinderen - Senior Analyst
First, I want to wish Kevin well. Maybe you can just update us on plans. I know we've had -- we've talked about this before in the past but plans to introduce another NAD increasing product and maybe timeline around that new product?
Robert N. Fried - CEO & Director
(technical difficulty) and we have, as you know, invested quite a bit in that process. There really isn't a company in the world that understands NAD the way ChromaDex does. There are a lot of companies that pretend to or try to steal the product. But there is really only one company that actually has this kind of patent portfolio on that level of this scientific expertise as ChromaDex. And these other molecules like NAR and NRH, we are going -- we are developing plans to commercialize them, but we have not announced them and we haven't yet given a timeline to. I've only said that it is important and then it is -- we recognize that it is important. And I think it's what's implied when we say we are investing in R&D with an ROI. But we need to do more than just learn about these molecules. We need to commercialize them, but at this time, we are not providing specific timelines or strategies.
Jeffrey Wallin Van Sinderen - Senior Analyst
Okay, fair enough. So just kind of stepping back from this, I mean, you know that I think you have a terrific product and amazing science behind it. However, our revenue growth has been decelerating since 2018. Guidance implies further deceleration of top line growth. Can you maybe give us a better sense of your plan to reaccelerate revenue growth? What are the specific elements of that plan? What drivers are needed to underpin that plan and maybe over what time frame you are thinking about reaccelerating growth?
Robert N. Fried - CEO & Director
So one thing that is important to look at is that there's a BD, a business development, business-to-business business here and a direct-to-consumer business here, 2 different ones. The direct-to-consumer business has steadily grown in that period that you are talking about. I don't know that we've had many quarters where we did more than 10% sequential growth as we did this quarter. And as we pointed out, it excluded that Amazon Prime, really, week, which is -- can be a very, very significant week. So our e-commerce business has been consistent and steady and is really coming off of a very, very strong second quarter. And it is our expectation that, that will continue.
It is the B2B side that's less predictable, deals like Walmart or Watsons or some of the other companies like Nestle to whom we supply the ingredients to. Sometimes they're steady and consistent, sometimes they're a little bit lumpy. The -- obviously the Watsons deal has been an extraordinary success for us. Some of the -- a couple of the ingredient partnerships have also been terrific successes, and some of the others have been sort of hits and misses. But I could see us doing a few more of those types of deals where we supply the ingredient carefully to partners that market it aggressively and help support the messaging. In that case, the brand would be Niagen, not Tru Niagen. But I think part of the growth is to spread the marketing commitment amongst a few other companies, not just us, to get the word out.
I also think that some of these international expansion opportunities are pretty significant. I mean, I don't want to count the money until we receive it. But we do have very, very high hopes for our relationship in -- our relationships in China. We commissioned a study last quarter estimating the size of the NAD market in China. We think the NAD market in China is more than $700 million, the current market, ingredients that are inferior to Niagen, but are selling like they are Niagen. And it's just many, many, many people telling the story and that's one of the reasons why we partnered with Sinopharm.
And then there are other opportunities with this -- with the molecule itself. It's not just the steady increase in awareness and growth of our e-commerce channels and perhaps other, perhaps, retail channels but it's also there are other ways to provide Niagen to consumers, not just dietary supplements, their foods and perhaps at some point drug indications and other ways to deliver it.
So we are exploring those and we understand that, that value is here at this company. When you control molecules like we have with the amount of science behind it and the efficacy that we are showing and the amount of research there, just selling it as a dietary supplement is probably limiting it. It's probably much bigger than that. And you know many of the indications that we've already seen positive either pre-clinical and in some cases, actually clinical studies. You've seen Cockayne's, you've seen COVID, you've seen Parkinson's, you've seen neuropathy, you've seen ALS, neurological in general, muscle health. I mean, there are many indications where nicotinamide riboside might provide some sort of therapeutic or prophylactic value or some complementary value to an existing drug.
So these are significant growth opportunities down the road for us while we continue to develop this core business of an e-commerce-based dietary supplement business that targets aging, using NAD and develops a product line of Niagen-specific dietary supplements.
Just as an added point to that last point, I've mentioned the importance of the intellectual property and the science behind nicotinamide riboside and there are companies who have challenged our intellectual property and/or who have made claims as though their product replicates NAD elevation the way Niagen does. There was a ruling from the patent office today that one of these companies that has challenged the patent -- the 807 patents that we possess on nicotinamide riboside, and that challenge was made by a company called Thorne and the patent office ruled against Thorne just today and in favor of ChromaDex and that 807 patent which we consider to be an important decision and important ruling for further solidifying the intellectual property that ChromaDex possesses.
