Thirty days. That is how long a supplement brand has, after it first markets a product with a structure/function claim, to notify the FDA that it is making the statement, and it is the condition furthest from anything a creator will ever say on camera, of the three the FDA attaches to the sentence. The other two are that the brand must have substantiation that the statement is truthful and not misleading, and that the statement must carry a disclaimer whose text is imposed word for word. A creator who says "this magnesium helps me sleep" in a video has, without knowing it, spoken a sentence that has a legal category on the label, a set of conditions behind it, and a footnote whose text the brand did not write.
Calm editing, the routine shot and the seven shots that work are in the guide to UGC for wellness brands; what follows is only the American rulebook a supplement brand has to add: which sentences are allowed, which are forbidden, what the disclaimer says, and what the Federal Trade Commission expects behind any of it.
Three kinds of sentence, three different regimes
The structure/function claim
The FDA's questions and answers on dietary supplements define a structure/function claim as a claim about effects on a structure or function of the human body, and group it with claims of a benefit related to a classical nutrient deficiency disease and claims of general well-being. "Supports immune health", "helps maintain healthy joints", "promotes restful sleep" are the classic forms. A brand may make them, and the FDA's labeling guide sets the three conditions: substantiation that the statement is truthful and not misleading, the disclaimer, and notification to the FDA no later than 30 days after the first marketing of the product with the statement, under 21 CFR 101.93.
The disease claim
A health claim, in the FDA's vocabulary, describes a relationship between a substance and reduced risk of a disease or health-related condition, and it requires significant scientific agreement and FDA authorization. A claim that a supplement treats, cures or prevents a disease is drug territory: the Federal Food, Drug, and Cosmetic Act defines drugs by intended use, and a product intended to treat a disease is a drug whatever it is sold as. The FDA's labeling guide states that a health claim can be a written statement, a third-party reference, a symbol or a vignette: the form does not matter, the relationship asserted does. Read into video, a creator who holds up the bottle while describing how their anxiety disorder went away has represented the product as treating a disease, and the FDA's own answer is that a product sold as a supplement and represented, explicitly or implicitly, for the treatment, prevention or cure of a disease meets the definition of a drug. No brand copy is needed for the claim to exist.
The disclaimer, word for word
The text is not the brand's to write. The FDA's guide gives it, in singular and plural, and states that it may not be modified: "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease." The FDA's questions and answers add that this disclaimer is required by law, under 21 U.S.C. 343(r)(6)(C). The guide's placement rule is a labeling rule: the disclaimer accompanies the statement on the label. For a creator video the honest answer is the one the FTC gives in its own guidance: the DSHEA labeling disclaimer is not required in other forms of advertising or marketing, many marketers include it anyway, and it never cures a claim the brand cannot substantiate. A brand that carries it into the video loses nothing; a brand that relies on it has misread what it does.
The label's categories are one thing and the video is another, whereas most briefs treat them as the same list. What the label has substantiated, notified and disclaimed is the vocabulary the video may borrow; what the FTC does with the same words is described below.
| What the creator says | What it is | What the brand needs |
|---|---|---|
| "Supports my immune system", "helps me stay regular" | A structure/function claim, the kind the label carries | Substantiated, notified and disclaimed on the label; read by the FTC in a video as a health claim needing competent and reliable scientific evidence |
| "Contains 500 mg of vitamin C per serving" | A quantitative statement of a nutrient amount | Accuracy, nothing more |
| "Cured my insomnia", "keeps me from getting sick", "lowers my blood pressure" | A disease claim, or a drug intended use | Not available to a supplement outside an FDA-authorized health claim; remove, retake, or reclassify the product |
| "Doctors recommend", "clinically proven" | An expert or substantiation claim | A qualified expert who examined the product, or the evidence, and the connection disclosed |
What the FTC expects behind the sentence
The FDA governs what the label and the labeling may say; the Federal Trade Commission governs the advertising, and it states that "advertising" covers social media and the whole range of marketing techniques. Its health products guidance sets one standard for claims about the health benefits or safety of dietary supplements: substantiation in the form of competent and reliable scientific evidence, held before the claim runs. The guidance also addresses the effect of the DSHEA disclaimer in advertising, and the point a brand should take from it is that the disclaimer is a labeling requirement, not a shield: a claim in an ad still has to be substantiated whatever the footnote says. The guidance says it in two lines: the DSHEA labeling disclaimer is not required in other forms of advertising or marketing, and it will not cure an otherwise deceptive ad. It adds that DSHEA's structure/function provisions govern labeling, not the FTC's reading of the same words in advertising, where every health-related claim is judged the same way whatever the FDA would call it.
Two further rules from the guidance shape the brief. Advertisers are liable for the misleading use of endorsements in social media as in any other medium, and should not make claims through a consumer testimonial that they could not substantiate if they made them directly. And any material connection between the endorser and the advertiser, payment, free product, a business relationship, must be clearly and conspicuously disclosed, which is the same disclosure the FTC's influencer guidance describes for every category.
The testimonial, which is the supplement video's whole point
The typical supplement video is a testimonial: a person describing what changed after they started taking the product. The FTC's guidance treats a testimonial as a claim the advertiser is making, and its own example is a marketer that pays a blogger to review its supplement and makes no claim itself; the blogger writes that the supplement cures acid reflux, the marketer has no evidence for that, and the marketer is liable for the misleading representation, and must disclose the payment besides. The typical-results mechanism, and what it does to casting, is the subject of the guide to UGC for fitness brands in the United States. For a brand the consequence is that a creator's testimonial has to fit inside what the brand can substantiate: a creator who says the product "helps me feel more energetic in the afternoon" is inside a structure/function claim the brand can support; a creator who says it "fixed my chronic fatigue" is outside everything.
The other consequence is casting. A brand that selects the creator with the most spectacular result has selected the least typical one, and the guide to UGC without followers in the United States describes credibility on camera as the first thing an American buyer looks for in a portfolio, ahead of any audience.
Writing the American supplement brief
- List the structure/function claims the brand has substantiated, in the exact words, and ask creators to stay inside them; a creator who reads "supports immune health" and says "keeps me from getting sick" has left the list.
- List the forbidden words: any disease, any condition, any medical diagnosis, "cure", "treat", "prevent", and the common ones in the category, anxiety, depression, insomnia, arthritis, diabetes.
- Put the disclaimer text in the brief as the brand's choice, not as a shield: the FTC does not require it in advertising and it cures nothing, but a creator who reads it learns in one sentence what the product may not claim.
- Ask the creator for the honest timeline of their own experience, and compare it with the typical result before the video runs.
- Never let a creator video be the first place a structure/function claim appears: the notification rule is a labeling rule, 30 days from first marketing the product with the statement on its label or labeling, and a sentence that is not already on the label, notified and substantiated, does not go in the brief.
