The 7 Words That Turn a $40 Supplement Into an Illegal Drug

On a long enough timeline, every marketer becomes their own narrator.

The FDA isn't reading your verb list, it's reading your intended use. One sentence on your sales page can reclassify your supplement as a new drug, and most founders never see the line they crossed.

The Problem: You Patched 5 Words. The Statute Reads 7.

Here's the pain: your lawyer reads your landing page and tells you to drop treats, cures, and prevents, you swap them for supports and promotes, and you feel safer with your compliance review signed off.

Then you pull a 2024 FDA warning letter off the agency database (fda.gov, 2024)¹, and the brand that ships almost the same product as yours wrote almost the same copy as yours. The letter reads their own words back at them. Restores cognitive function. Alleviates joint pain. Both verbs ship in your live ad set right now, and neither one hit your lawyer's cheat sheet.

Here's why your compliance review missed them. The Food, Drug, and Cosmetic Act defines a drug at §201(g)(1)(B) (Cornell Law, 21 U.S.C. §321) as anything intended "for use in the diagnosis, cure, mitigation, treatment, or prevention of disease" (21 U.S.C. §321(g)(1)(B), 2024)². Five verbs, and most regulatory cheat sheets stop there with that statutory list.

The FDA doesn't stop there. Warning letters reach for two more verbs that ride the same intended-use test (FDA Warning Letters, fda.gov, 2024)³, because alleviate and restore both ride on the disease the marketer named in the surrounding copy. Both verbs show up in FDA structure-function compliance examples (FDA SECG, 2002)⁴, and both still trip founders every quarter.

You audited the 5 verbs your lawyer named. The FDA reads 7.

The philosophical problem lifts founders out of bed at 2 a.m. The product on your shelf does not change, the bottle does not change, the capsules do not change. The words on the website change the regulatory classification of the product itself, and you wrote your way into a drug under the federal definition.

The Guide: I Read The Statute And The Warning Letters

I read §201(g)(1)(B) on Cornell Law (Cornell, 21 U.S.C. §321)². I read the FDA Small Entity Compliance Guide on Structure/Function Claims, dated January 9, 2002 (FDA SECG, 2002)⁴. I pulled dietary supplement warning letters off fda.gov for 2024 and 2025 (FDA, 2024)¹, and read every one of them.

I opened this audit thinking the line was just the five verbs in the statute, and that swapping them for supports would close the gap. Then I read the warning letters, and the line is wider than the statute. Two more verbs ride on the same intended-use logic, and the warning letters hit them every quarter.

Here's the structural test: the FDA doesn't read your verb in isolation, it reads your intended use. Intended use is a legal term, and the agency reads it from the totality of your marketing materials, which includes your label, your website, your testimonials, your podcast ads, and your Amazon and TikTok Shop listings.

The agency asks one question: does the marketing position the product to diagnose, cure, mitigate, treat, prevent, alleviate, or restore a condition the consumer would recognize as a disease? If the answer is yes, the product is classified as a drug, and a new drug needs FDA approval under §505 of the Act (Cornell, 21 U.S.C. §355)⁵ before it ships into interstate commerce.

The failure mode here, the inversion Munger would draw, is reading the verb in isolation. Founders grep for treats, strip every hit, and feel done with the compliance review. The FDA reads the verb plus the named condition plus the surrounding product context. Supports memory health reads as a structure-function claim, but supports memory loss recovery reads as a disease claim. The verb didn't change. The named condition did.

The DSHEA 1994 carve-out gave dietary supplements a narrow runway for structure-function claims (DSHEA, Public Law 103-417, 1994)⁶. You can describe a structure or a normal function in the body. A brand can say a product "helps maintain healthy blood pressure already within the normal range," but it cannot say the product "lowers blood pressure." The first sentence reads as a function on a healthy body. The second sentence names a disease state and hits it.

Seven words sit on the wrong side of that runway. Five come from the statute itself, and two come from the persistent pattern in warning letters. The seven verbs are: diagnose, cure, mitigate, treat, prevent, alleviate, restore.

The Plan: Run The 7-Word Audit

Here's the play. Open your live site, your Meta and Google ad accounts, and your last 30 days of podcast reads. Run each verb against the copy, and read every hit in context. The order below runs from "fastest to grep" to "needs a records pull."

1. Grep for the 5 statutory verbs first. Diagnose, cure, mitigate, treat, prevent. Read every hit in context and drop or rewrite any sentence pairing the verb with a named condition. Why this works: §201(g)(1)(B) names these five (Cornell, 21 U.S.C. §321)², and they hit FDA enforcement faster than any other verb pair on the page.

2. Grep for the 2 warning-letter verbs next. Alleviate and restore. These two verbs ride on the same intended-use test (FDA SECG, 2002)⁴. Restores joint mobility on a knee-pain landing page reads as a disease claim. Restores skin tone on a sun-damage testimonial reads the same way. Drop the verb or rewrite the surrounding context around it.

3. Read the testimonials. Net impression doctrine pulls testimonial language into your case file. A testimonial saying "this product cured my migraines" makes a disease claim on your behalf, even if your own label reads only "promotes head comfort." The FTC's 2023 Endorsement Guides update killed the results not typical workaround for non-representative testimonials (FTC, 16 CFR 255, July 26, 2023)⁷. The testimonial belongs to your brand.

4. Read the ambassador and influencer scripts. The same rule hits creator content. If an influencer writes "I started taking this product after my arthritis diagnosis" and tags your brand on Instagram or TikTok, the post ships as your marketing. Pull three random posts off each platform, and read each one against the 7-verb list.

5. Read the podcast reads. Host-read advertisements run past lawyers because they're audio and rarely transcribed. A host saying "this supplement basically reversed my mom's joint pain" writes a disease claim on your brand. Reverse isn't in the 7-verb list, but the net impression is. Pull last quarter's reads off Spotify and Apple Podcasts and read each transcript.

6. Score the pattern, not the individual word. A single instance of restore on a structure-function landing page is rarely the smoking gun. Six instances across your site, your podcast, and your ambassador deck reads as documented intended use. Count every hit.

7. Fix or cut. The safe rewrites are short: supports, helps maintain, promotes. The three verbs name a function on a healthy body and don't act on a condition. If the copy needs the disease verb to sell the bottle, the product isn't a supplement under the regulatory definition anymore, it's a drug, and you need FDA approval before you ship the next batch into interstate commerce.

Step 1 takes 20 minutes per channel, and step 5 takes the longest. The audit runs in one Saturday morning, and the warning letter gives you 15 working days to respond (FDA Regulatory Procedures Manual, fda.gov)¹. The Saturday morning wins.

The Stakes: What The Warning Letter Actually Costs

The warning letter itself carries no direct monetary fine, and the cost hits everywhere else in the business once it lands. The 2 a.m. founder panic from earlier in this article shows up now as a chain of phone calls.

Your retailer reads the letter on fda.gov the day it ships and pulls your purchase orders pending response. Your payment processor reads the account for compliance risk. Your insurance carrier raises your product liability premium at the next renewal cycle. A class-action firm reads the letter and files a complaint. The FTC reads the same letter and opens a parallel investigation under Section 5 of the FTC Act, and Operation CBDeceit (FTC, December 17, 2020)⁸ hit six CBD sellers, with five sellers paying civil penalties ranging from roughly $20,000 to $85,000 per case (FTC, 2020)⁸.

The product on the shelf never changed, but your label flipped, and the cost hits every channel that touches the brand.

The Call: Run The Audit This Saturday

Open your site this Saturday morning, grep for the 7 verbs, read every hit in context, and rewrite or cut. Open your testimonials, your influencer posts, and last quarter's podcast reads, and run the same audit. The product on your shelf doesn't change. The words on your website are the product the regulator reads. Patch the lines and ship the new copy before the letter arrives.

I am Jack's smirking revenge.
