The Supplement Industry Still Has a Claims Substantiation Problem. Here's How to Fix It

Posted by Douglas Kalman, Ph.D., R.D., CCRC, FACN, Vice President of Scientific Affairs on Wed, Jan 30, 2019

For the past decade, I've written and educated industry about the benefits of substantiating dietary supplement claims, from the rationale of complying with national regulatory rules to remaining ahead of the innovation curve.

But despite policing from the U.S.-FDA and FTC, and the negative media attention surrounding offending brands, the supplement industry still has a substantiation problem. There are far too many instances of companies under fire (or yet to be under fire) for unsubstantiated, misleading, or deceptive claims.

The good news is that this can be fixed with a clearer understanding of what qualifies as substantiation and how companies can benefit from making the investment in quality research. Read on to find out what you need to know.

Claims Substantiation: A Brief History

In the U.S., the FDA and FTC have rules for substantiation. The FTC uses the "reasonable basis doctrine" which says that substantiation must be gathered before a product is advertised, not after. This means the FTC does not like to review research conducted after a company is questioned or challenged. The reasonable basis doctrine is also sometimes called “The Pfizer Factors.”

It is more cost-effective (and optimal in the eyes of the FTC) if pre-marketing clinical trials are done to support the product's claims and other marketing statements as opposed to research initiated to support a claim after the offending company has received a regulatory hit or civil lawsuit.

More detail can be found in the FTC's dietary supplement advertising guidelines.

What Level of Scientific Evidence is Needed to Support Claims?

There are various types of studies and study designs, and the type of study matters. Pilot trials, endorsements, testimonials, and "borrowed science" are simply not enough. These are certainly weak pillars to rest laurels upon. Disease claims (prevent, cure, or treat) still lead the “no-no’s” for advertising and marketing dietary supplements.

Red flag categories where (more often than not) the marketing does not live up to the hype include weight loss, cognition/memory, and blood sugar control. This means if you operate or sell in these FTC red flag zones, your products will come under greater scrutiny.

Greater scrutiny means you need to have a reasonable basis for making the claims that you do, as non-governmental and governmental agencies will be watching you – online, in brick-and-mortar stores, and on the radio airways.

What qualifies as substantiation? In 2010, the FTC outlined four criteria which still influence decision-making today:

1. At least two well-controlled human clinical studies

2. of the product or a substantially similar product

3. conducted by different experts independently of each other

4. that conform to acceptable designs and protocols and whose results, when considered in light of the body of relevant and reliable scientific evidence, are sufficient to substantiate the health claim.

Yes, various court rulings since 2010 have indicated a single well-designed study might be sufficient for substantiation support. However, as recently as 2018, the FTC was still noting its preference for at least two randomized, double-blind, placebo-controlled clinical trials that are well-designed, powered sufficiently, and carried out in an ethically clean manner as being the minimal standard they are looking for to substantiate an ingredient or finished product.

Essentially, anything other than the "gold standard" of clinical research—the randomized, double-blind, placebo-controlled clinical trial—will simply not be regarded as highly as other types of science.

How Industry Can Prioritize Substantiation (And Why They Should)

Of course, there are many shining examples of companies doing it the right way (including our clients) by investing in proper clinical research to support product marketing.

How do they do it, and what is involved?

The challenge for companies is to stay one step ahead of the regulations and competitors. Fortunately, this is both achievable and cost-effective when done correctly.

Below are some best practices for substantiating dietary supplement claims today:

1. Conduct background research to learn and know as much as possible about each ingredient in your finished product. Review the science to make sure that the ingredients you are choosing have merit, both on their own and in combination.

2. When designing a product, consider examining the United States Patent and Trade Office for any patents your product may infringe upon, as well as if your product has potential to be patented.

3. Invest in clinical research during the "concept" stage of product development, before a product is marketed.

4. If unsure how your product may do in an objective study, and insecure about spending sizable amounts of money on research, first consider building with a "feasibility study", also known as a "proof-of-concept” study. Once the concept shows merit (statistically speaking), then you can move on to the more robust randomized, double-blind, placebo-controlled studies.

5. After the first study, consider submitting it to a peer-reviewed journal for publication. This helps as part of your substantiation portfolio.

6. Consider a second well-designed clinical study, as these are often less costly than anticipated.

7. Again, consider publishing the studies on your product in the peer-reviewed scientific literature. This type of transparency helps build confidence from both the healthcare professional sector and the general population (consumers).

8. Take a page from pharma and continue to do post-marketing studies on your product as a means of adding substantiation and creating a point of differentiation.

9. Gather an outside scientific advisory board to provide you with guidance, feedback, and a mechanism to stay compliant with not only the regulations, but the spirit of the law as well.

10. Remember that the cost of litigation as related to government or civil lawsuits for unsubstantiated claims (or for false and misleading advertising and marketing) is often many folds greater than what a study would have costed you. Why take such a risk?

This post is meant to be brief and is a topical overview of substantiation, not a point-by-point, in-depth guide of how to remain compliant with laws and regulations and engender greater consumer confidence in your product and brand. Substantiation is often a major difference between you and a fly-by-night competitor.
