Supplement FDA Warning Letter Language, 5 Phrases to Strip
On this page
Loot Goblin Marketplace (@LootGoblinMarketplace), a 168K-subscriber YouTube channel, has run 75 paid Gamer Supps slots since November 2024 in our deal log, which is roughly one a week and tells you Gamer Supps, a gaming-focused energy supplement brand, runs the creator on an always-on script rather than one-off insertions. A supplement founder messaged me last week wanting to license that same creator's exact ad copy for her own pre-workout brand. The 90-second answer was no. The line her team flagged as the good one is the same kind of line the FDA pulled into warning letters to other supplement brands this year.
Across the 1,437 Gamer Supps deals across 201 creators in our database since 2024, the FTC #ad disclosure rate in the descriptions we scanned sits near zero, which is the creator-side failure pattern the agency cites first when it opens a supplement file. The Teami refund order from 2020 was the brand-side version of the same lesson. The price tag was $930,000.
The five phrases
Five patterns show up in current FDA supplement warning letters and in the 2020 FTC Teami complaint. Each one moves a post out of the safe zone.
First, the disease verb. The post says the product treats, cures, prevents, or reverses a condition. The FTC's Health Products Compliance Guidance names this as the cleanest single trigger. Rewrite the verb to support, help, or maintain.
Second, the named condition. The post mentions diabetes, anxiety, depression, cancer, or insomnia by name. Once you name a disease, the FDA treats the post as drug-class marketing under DSHEA, the Dietary Supplement Health and Education Act, the 1994 law that governs supplements. Strip the condition. Replace anxiety with stress response.
Third, the prescription comparator. The post says works like the prescription, or a natural alternative to a drug name. This is the second most-quoted pattern in FDA letters after the disease verb. Strip the comparator entirely.
Fourth, the drug-class claim. The post calls the product anti-inflammatory, antibiotic, or hormone-balancing. These read as pharmacological claims. Rewrite to ingredient-spotlight language about the published research on the ingredient.
Fifth, the strong-testimonial-as-claim. The creator says my doctor took me off my medication after taking this. Teami was built on this exact pattern. The FDA and the FTC treat a first-person testimonial as a brand claim the moment the line implies the supplement replaced a drug.
Five phrases, five rewrites. Here is the past-60-post language audit we run on every supplement creator before outreach.
Testimonial vs claim
The FDA treats a first-person testimonial as a brand claim the moment the line names a condition the supplement is implied to treat.
A creator who says I feel more focused after my AG1 is inside the safe zone. The line names a system. A creator who says I stopped taking my ADHD meds after I started this is outside the zone. The line names a condition and implies the supplement replaced the drug.
The split sits on two words. Implies and replaces. The FTC built the Teami $930K refund order around exactly this pattern. The agency's original 2020 Teami complaint names Cardi B, Jordin Sparks, and a long list of paid endorsers whose posts ran weight-loss claims without disclosure.
A safe rewrite: take the line my doctor said my cholesterol numbers are better than they have been in years, and rewrite to I have been adding the green powder to my routine and I like how I feel in the morning. The second one is a structure-and-function claim. The first one is a disease claim. Send us a draft script and we will hand back the safe-zone rewrite within 48 hours.
The brand pays the refund. Not the creator.
Structure vs disease
Structure-and-function language is the FDA's named safe zone under DSHEA. The FDA structure/function claims page names the rule. The product can describe how it affects a structure or function of the body. It cannot claim to diagnose, treat, cure, or prevent a disease.
Three levels.
Level 1 is the disease verb that triggers the letter. Treats anxiety. Cures insomnia. Reverses pre-diabetes. Strip on sight.
Level 2 is the structure-and-function hedge that survives most reviews. Supports a healthy stress response. Helps maintain sleep quality. Supports healthy blood sugar already in normal range. Each one names the system.
Level 3 is the language a brand can defend at hearing. Level 2 phrasing, paired with the required DSHEA disclaimer, paired with substantiation in the brief, paired with an ingredient page that cites the published research.
The comparator trap sits underneath all of this. A creator who says this works just like the prescription has dragged the product into the drug category in one sentence. The 2023 FTC announcement on the revised endorsement guides makes this a brand-side liability by default.
Comparators are the trap.
Worried your roster is sitting on Level 1 language? We pull every paid post on every creator on a shortlist, flag every disease verb and every comparator phrase, and hand back the rewrite list before the brief goes out. The pass runs free against any shortlist of up to twenty creators.

The AG1 safe zone
The AG1 podcast read is the workable script at scale in the category. AG1, short for Athletic Greens, a multi-vitamin powder, ships across the largest podcasts in the world and we have not seen an FDA letter on the brand. In our deal log, Andrew Huberman, a 7.5M-subscriber podcaster, ran 21 AG1 reads from October 2025 through February 2026. Tim Ferriss, a 1.77M-subscriber podcaster, ran 40 AG1 reads across June 2023 through March 2026.
The pattern decomposes into four moves a smaller brand can copy.
Move one. Open on a structure word, not a disease word. The host says it supports my morning energy or it helps me hit my greens target. The host does not say it cured my fatigue.
Move two. Anchor in personal habit, not in a medical outcome. The line is I drink this before my first meeting. The line is not I no longer feel depressed in the afternoons.
Move three. Front-load the disclosure. The verbal sponsor mention lands in the first 30 seconds. The on-screen text overlay sits under the ad read. The description carries #ad and the link. Move four. Hand the creator the substantiation file with the brief. The creator never has to invent a claim because the approved language is right there.
Most teams over-spend on the slot and under-spend on the brief that would have prevented the warning letter. Here is the AG1-pattern brief template we hand brands at outreach stage.
Four archetype scripts
Four script patterns survive review. Each one is anchored to a creator and brand from our deal log.
Archetype one is testimonial-bounded. The creator names their own habit and how the product fits. Catherine Gregory, a 121K-subscriber wellness creator, has run 50 AG1 reads since November 2023 in this pattern. She talks about her morning routine. She does not talk about a condition she fixed.
Archetype two is structure-and-function. The creator names the system the supplement supports. Institute of Human Anatomy, an 8.75M-subscriber health-education channel that quoted us $6,500 for one 60-90 second mid-roll integration, runs this pattern. The script talks about what nutrients do in the body. The script does not promise the product fixes a disease.
Archetype three is ingredient-spotlight. The creator walks through one or two named ingredients and what the published research says. The product is mentioned as the delivery vehicle. Eric Cressey, a 57.6K-subscriber strength coach, has run 13 AG1 reads in this style. The hook is the research, not the cure.
Archetype four is lifestyle-frame. The creator places the product inside a daily ritual and stops there. Kara and Nate, a 4.46M-subscriber travel duo, have run 18 AG1 reads on the road. The script is they pack it. They drink it on travel days. No medical claim ever lands.
Four archetypes. Four scripts the brand can hand a creator on Monday. None of them need a legal rewrite on Friday.
FAQ
What phrases does the FDA actually quote in supplement warning letters?
Five patterns recur. A disease verb (treats, cures, prevents). A named condition (diabetes, anxiety, cancer). A prescription comparator (works like the drug). A drug-class claim (anti-inflammatory, antibiotic). And a strong-testimonial-as-claim (my doctor took me off my medication after this). The FDA names each pattern in current warning letters. The FTC built the Teami $930K refund order around the same five.
Why was the Teami FTC settlement $930K and what changed after?
Teami paid $930,000 in 2020 after the FTC said the brand and its paid creators ran weight-loss and disease-style claims without clear disclosure. Cardi B and Jordin Sparks were named in the complaint. The 2023 update to 16 CFR Part 255 hardened the clear-and-conspicuous standard. The brand pays the refund and the multi-year consent order, not the creators.
What does a supplement script look like that survives FDA and FTC review?
The AG1 pattern. Structure-and-function language only. No disease verbs. No prescription-drug comparators. Verbal disclosure in the first 30 seconds. The DSHEA disclaimer on label and on screen. Andrew Huberman and Tim Ferriss run this pattern across 21 and 40 deals in our log respectively without drawing a letter.
Where We Come In
A supplement brand running a 200-creator roster with one disease verb in one script is one enforcement letter away from a Teami-style postmortem. We read every supplement creator's last 60 paid posts against the live FDA and FTC warning-letter language bank before a brand sends the first outreach email. The phrases the agencies pull this quarter are not the phrases they pulled last year. A brand running a stale script library is the brand that pays the next nine-figure refund.
Most supplement teams over-spend on creator fees and under-spend on the 30-minute language pass that would have caught the problem at brief stage. Speak with us when the next script is the one you cannot afford to get flagged.
Compliance is the moat.
