Supplement Store Promotions and the FTC
Supplement store promotions that stay compliant: starter kits, refills and free samples, with the FTC health claim guidance and FDA label rules.
Supplement store promotions look like any other store's: a starter kit, a free sample, a refill offer. What changes is the second layer under every one of them. A discount banner, a kit name or a product photo is advertising, and in this category the advertising is held to rules about what a product can be said to do. This page maps three promotions onto the Federal Trade Commission's health claim guidance and the Food and Drug Administration's rules for supplement labels, in plain language. It makes no health claim about any ingredient, even as an example, and it is not legal advice. Have counsel read your offer copy, and confirm anything specific to your products with the agencies.
A promotion does not change the claim rules
The FTC's Health Products Compliance Guidance applies to advertising of health products, supplements included, and its starting point is short. Per the guidance, advertising must be truthful and not misleading, and advertisers need adequate substantiation for all objective product claims conveyed, expressly or by implication. It describes the evidence it expects for health benefit claims as "competent and reliable scientific evidence," meaning tests, analyses, research or studies conducted and evaluated in an objective manner by experts in the relevant field, and generally accepted in the profession to yield accurate and reliable results.
Three points in that guidance matter for a promotion.
- Implied claims count. The FTC looks at the consumer's understanding, not the marketer's intent, and says marketers cannot suggest benefits indirectly if they could not claim them directly. A kit named for an outcome carries that outcome as a claim, whatever the fine print says.
- Your support has to match what you say. The guidance says marketers must have at least the level of support they claim to have. A banner that says "science-backed" needs the science to back that sentence.
- The same principles apply to any health-related product. Moving the claim from a product page to a promotional banner does not move it outside the guidance.
So the first review of a supplement promotion is the copy, not the discount: every sentence in the banner, the kit name, the email and the product page that says or implies what the product does.
Names, pictures and banners can be claims
The FDA's rule at 21 CFR 101.93 draws a line between a permitted structure or function statement and a disease claim. For a supplement, a statement that describes the role of a nutrient or dietary ingredient in affecting the structure or function of the body may be allowed, subject to the rest of the section, provided it is not a disease claim. If a supplement's label or labeling bears a disease claim, the section says the product will be subject to regulation as a drug unless the claim is an authorized health claim for which the product qualifies.
What makes this relevant to a promotion is the list of ways the regulation says a statement can claim to affect a disease. Besides naming a disease directly, it lists an effect on a disease through the name of the product, through a statement about its formulation, through a citation of a publication that implies treatment or prevention, through the use of the term "disease," and through pictures, vignettes, symbols or other means. The regulation is written for a product's label and labeling, and FDA says it will consider the context in which a claim is presented. Whether a kit name or a banner image is treated like the product name or a picture on the label is a question for counsel; as planning advice, treat them as if they were.
As planning advice, not an FDA rule: name kits for what is in them or how long they last, such as "30-day starter kit," not for an effect, and keep imagery to the product.
The structure and function statement and its disclaimer
If you do make a permitted structure or function statement, 21 CFR 101.93 sets conditions. Within 30 days after first marketing a supplement that bears such a statement, the manufacturer, packer or distributor must notify FDA that it has included the statement on the label or in the labeling, and the notice includes a certification that the firm has substantiation that the statement is truthful and not misleading. The disclaimer has a required text for one statement: "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." For more than one statement, a plural form is allowed.
The section also says where the disclaimer goes: adjacent to the statement with no intervening material, or linked to it with a symbol such as an asterisk placed at the end of the statement and next to the disclaimer. On labels and labeling it must appear on each panel or page where such a statement is, in boldface type no smaller than one-sixteenth inch.
The regulation is written for the label and labeling. We cannot tell you from its text whether a product page or a promotional banner counts as labeling in a particular case, so ask counsel. As planning advice, not an FDA instruction: if a banner repeats a structure or function statement, put the disclaimer next to it in the same view instead of one click away.
A free sample is still a supplement
A sample of a supplement is a supplement. 21 CFR 101.36(a) says the label of a dietary supplement that is offered for sale shall bear nutrition labeling in accordance with the section unless an exemption in the section applies, and the section sets out the Supplement Facts format, starting with the serving size and servings per container. The regulation's text does not say whether a free sample "offered for sale" falls under that sentence, and we found no statement that it does not. So do not assume a sample can skip the panel. Ask the FDA or counsel before you ship a sample in a plain sachet, and treat the same claim rules as applying to the sample's packaging and to the offer that gives it away.
If you advertise the sample as free, the FTC's guide on the word free (16 CFR 251.1) also applies: the conditions belong at the outset of the offer, and the shopper has a right to believe you will not directly and immediately recover its cost by marking up the price of the item they must buy. Free Sample With Purchase: A Test Plan covers the test, and Beauty Promotions: Samples, Minis, Bundles covers the parallel labeling point for cosmetics, so none of that wording is repeated here.
Starter kits and the price math
A starter kit is a fixed bundle: the product, its companion and the accessory that makes the routine easy, sold at one price. The math is the same as any bundle, and none of it needs a health claim. Bundle Pricing That Keeps Your Margin covers how deep the discount can go.
A worked example with invented numbers. Product A sells for 36 dollars with a landed cost of 9.00 dollars, product B for 34 dollars with a landed cost of 8.00 dollars, and a scoop for 12 dollars with a landed cost of 2.00 dollars. Sold separately they bring 82 dollars and cost 19.00, a margin of 63.00 dollars. A starter kit at 74 dollars costs the same 19.00 and returns a margin of 55.00 dollars, a discount of 8 dollars, or 9.8 percent, which leaves a margin of 74 percent of the kit price. The question is whether the kit brings enough first orders that would not have happened otherwise to cover the 8 dollars given up on the ones that would. Shipping and payment fees come out of both sides.
Name the kit by its contents, show the regular prices of the parts, and keep the savings figure true.
Refills and repeat purchase
A supplement is a repeat product, which is why the refill, not the first order, carries the lifetime value. Customer Lifetime Value on Shopify, Plainly shows how to count it. For timing, the label gives you the number you need: the Supplement Facts panel states servings per container, and divided by the servings per day on the directions it tells you how many days a container lasts. A refill reminder should arrive before that day, not after. Salt Lake City Refill Offers for DTC Brands has a cycle-pricing plan for refill products, and keeping the refill copy to the product, the cycle and the price avoids a claim in the reminder.
Reviews and endorsements in promotions
Promotions often borrow customer voices, and in this category a testimonial can be a claim. The FTC's health guidance says it is not enough that a testimonial represents the honest opinion or experience of an endorser: advertisers should not make claims through testimonials that would be deceptive if made directly.
Two further rules sit on top. The endorsement guides, 16 CFR 255.5, say that a connection between an endorser and the seller that might materially affect the weight or credibility of the endorsement, and is not reasonably expected by the audience, must be disclosed clearly and conspicuously, and that material connections include the provision of free or discounted products to an endorser, whether or not the advertiser requires an endorsement in return. And the FTC's rule on consumer reviews, 16 CFR 465.4, makes it an unfair or deceptive practice to provide compensation or other incentives in exchange for, or conditioned expressly or by implication on, a review expressing a particular sentiment. Its definition of buying a review includes giving products, discounts or coupons.
So a "free sample in exchange for a five-star review" is out, and a sample sent to an influencer needs a disclosure. A generalized request to buyers to share their experience, with no condition on what they say, is a different thing; confirm the line with counsel.
Building a starter kit
Start from the Classic bundle template in Freebies Engine by Log Studio Lab, described in the catalog as "Fixed products sold together at a bundle price." Enter the parts, set the kit price from the margin table above, and write the name and banner from the contents and the duration, not the effect. Plan requirements for bundle templates are on the pricing page.
Before you launch, run a one-page review: every sentence of the offer copy, the kit name, the image, the featured reviews and the sample packaging, against the points above. This is not legal advice.
