Supplement advertising examples: what gets rejected, and the rewrite that passes

The three rulebooks every supplement ad answers to

A supplement ad is checked by three different referees, and they catch different things. Passing one tells you nothing about the others.

The FTC

The FTC’s current rulebook is the Health Products Compliance Guidance, published in December 2022. It replaced Dietary Supplements: An Advertising Guide for Industry from 1998, which is why people still search for the old title.

The core rule has not changed: a health claim needs “competent and reliable scientific evidence” before the ad runs. For a claim about a health benefit, the FTC says that generally means randomised, controlled human clinical trials. Animal studies and customer stories are not enough on their own.

The FDA

Supplements may make structure/function claims, such as “supports healthy digestion”, but not disease claims such as “treats IBS”. A structure/function claim comes with three obligations: evidence that it is true, a notification to the FDA within 30 days of first marketing the product, and this disclaimer on the label:

The FTC is clear that this disclaimer does not rescue a misleading ad. It is a labelling requirement, not a shield.

Meta and Google

The platforms are stricter than the law in places, and they decide in minutes rather than years. Meta requires supplement and weight-loss ads to target people aged 18 or over, bans copy that asserts or implies anything about the viewer’s health, and bans “statements of inferiority” about appearance. Google bans supplements that imply they work as well as prescription drugs, and any unapproved product marketed as preventing, treating or curing a disease. Some violations of Google’s unapproved-substances rules can suspend the whole account, not just the ad.

Six patterns, with the version that fails and the version that passes

1. The disease claim

The fastest way to turn a supplement into an unapproved drug, in the FDA’s eyes, is to name a disease or its symptoms as the thing it fixes.

“Anxiety” is a condition; “a calm mood” is a normal function. The asterisk points to the disclaimer on the landing page. The rewrite still needs evidence behind it, and the timeline was dropped because it is a separate claim that needs its own proof.

2. The personal-attribute call-out

Meta’s rule is about the ad talking to the viewer as if it knows their body or their health. It applies to indirect phrasing too, not only to “you”.

Lead with the product and what is in it, not with the viewer and what is wrong with them. It reads as more confident, too.

3. The before-and-after image

This is not a flat ban. Meta prohibits statements of inferiority about appearance and specific images, such as close-ups of someone pinching fat, and a before-and-after that reads as a body put-down falls straight into that. For weight loss it is one of the formats most often rejected. Even where one runs, the FTC requires the result shown to be what a typical customer can expect.

If transformation is the story, tell it with routine, energy and habit rather than the body. That keeps the ad on the right side of the inferiority rule and away from a typical-results problem.

4. The testimonial that says too much

A customer review is still your ad. The FTC’s position is that you cannot use a testimonial to make a claim you could not prove yourself. A small “results not typical” line does not fix a dramatic result, either: the ad has to make clear what people can generally expect.

The first is a disease claim in a customer’s voice. The second is about the experience of taking the product, which is true, specific and makes no promise.

5. “Clinically proven”

“Clinically proven” is a claim that a clinical trial exists and shows the effect. The FTC guidance expects the evidence to fit the claim: the right population, a meaningful dose, and a product the same as or essentially equivalent to yours. A study on an ingredient at a different dose does not prove your product works.

The rewrite states a fact you can show. Only use it if the dose really does match the research. If you have a trial on your own formula, say exactly what it measured.

6. Urgency and scarcity

A real deadline or real stock limit is fine. A countdown timer that resets on every visit, or “only 3 left” on a product you have thousands of, is a false claim like any other.

Examples by format

The same rules apply everywhere, but each format has its usual weak spot.

• Static image. The weak spot is on-image text. Reviewers read the words in the picture as closely as the caption. Keep claims off the image and let it show the product, the format (capsule, powder, gummy) and one plain fact.
• UGC video. The weak spot is what the creator says unscripted. Give them a brief listing the phrases they can use, and review the cut before it runs. A creator saying “it cured my…” is your disease claim.
• Search ad. The weak spot is headline keyword insertion. A headline that inserts the search term can end up saying “Supplement for Arthritis”. Write fixed headlines for health searches.
• Landing page. The weak spot is that the platforms read it too. A clean ad sending traffic to a page full of disease claims is still rejected, and the page is where the FTC will look. This is where the disclaimer, the evidence and the honest version of the claim belong.

Where to advertise supplements

For most brands starting out, Meta finds the customers and Google Search catches the demand that Meta creates. Creators feed both with material that performs better than studio work. We have left out benchmark numbers on purpose: costs vary too much by product and price to quote honestly.

A pre-launch checklist

Run every new supplement ad through these ten questions before it goes live.

1. Does any line name a disease, condition or symptom as something the product fixes?
2. Does any line talk to the viewer as if it knows their health, body or weight?
3. Does anything suggest the viewer looks wrong, or show a body part as a problem?
4. Is there a study behind every claim, on the right dose and a matching product?
5. Do testimonials only say what you could prove yourself, and reflect typical results?
6. Does “clinically proven”, “doctor recommended” or a number appear anywhere without proof on file?
7. Is targeting set to 18+ for supplement and weight-loss campaigns on Meta?
8. Is every ingredient clear of Google’s unapproved-substances list?
9. Does the landing page match the ad, carry the FDA disclaimer next to structure/function claims, and avoid disease claims too?
10. Are deadlines, discounts and stock counts real?

If any answer is the wrong one, fix it before launch. A rejection costs a day; a pattern of rejections can cost the ad account.

This is the same check we run on every ad before it goes live for a client. If you want it run over the account you already have, that is what the free growth review below is for.
