Affiliate marketing in healthcare: rules by product type

In the US, affiliate marketing in healthcare covers four kinds of products: supplements, OTC products, devices and wearables, and telehealth programs such as GLP-1 weight loss. FTC claim and disclosure rules cover all four. FDA, ad-platform and health-data limits then differ by category, and GLP-1 telehealth, the worked example on this page, touches every one of them.

The four health categories affiliates can promote

Affiliate marketing in healthcare covers four product types, and each one sits under a different mix of regulators. The pay model (usually per sale or per lead) does not change the content rules.

• Supplements. FDA describes a dietary supplement as a product intended for ingestion that contains a “dietary ingredient,” such as a vitamin, mineral, herb or amino acid.
• OTC products. Nonprescription drugs. FDA has primary responsibility for labeling, and the FTC has primary responsibility for advertising.
• Devices and wearables. Fitness trackers, sleep trackers and other noninvasive products that sit near the line between wellness and medical devices.
• Telehealth Rx programs. A provider’s program with a clinical visit and a prescription, such as GLP-1 weight loss. The affiliate promotes the program, not the drug. For pharmacy-style offers, see online pharmacy affiliate programs.

For a comparison of actual programs, see health affiliate programs. This page covers only what the content has to do.

Rules by category

Each health category has its own claim limit, its own list of phrases to avoid and its own main risk. The table below maps the four categories to the rules that bind affiliate content, as of November 2, 2026.

FTC rules that apply to every health category

The FTC’s Endorsement Guides apply to every product type in the table. Four rules do most of the work for an affiliate.

Disclose the commission next to the link. The FTC’s FAQ says “paid link” right next to an affiliate link should be an adequate disclosure. It also says consumers might not understand “affiliate link,” and a “buy now” button does not work. A single disclosure on a home page is not enough. A disclosure in a comment, or behind a button that links to the full text, is easy to avoid, so it does not count as clear and conspicuous. In a video, disclose in the video itself and near the links in the description.

Say what typical results are. The FTC FAQ says statements like “Results not typical” do not change how an ad’s result claim is read. The advertiser needs proof that the result is typical, or a clear statement of the generally expected result. The FAQ’s own example is an endorser who says she lost 50 pounds in 6 months. The FTC’s Health Products Guidance (Example 41) applies the same rule to a weight-loss supplement.

Testimonials count as the company’s claims. The Guidance says advertisers should not make claims through testimonials that would be deceptive or unsubstantiated if made directly. In Example 40, a marketer pays a blogger who writes that a supplement cures acid reflux. The marketer is liable for that claim, and the post needs a clear disclosure of the payment.

Health claims need strong substantiation. The Guidance says claims about the health benefits or safety of health products generally need competent and reliable scientific evidence. A “Results not typical” line or a DSHEA-style disclaimer does not cure a misleading claim.

For paid social posts, see GLP-1 influencer rules.

Who is liable when an affiliate’s content is wrong

The advertiser carries most of the FTC’s attention, but it is not the only party. The FTC’s Health Products Guidance says anyone participating in deceptive marketing is potentially liable, including ad agencies, distributors, retailers and expert endorsers. Its endnote cites FTC v. LeadClick Media, 838 F.3d 158 (2d Cir. 2016), described there as an affiliate advertising network case.

On individual endorsers, the FAQ says enforcement focus usually falls on advertisers or their agencies. It adds that action against an individual endorser might be appropriate, for example if the endorser has not made required disclosures despite warnings. It also says a non-expert endorser may be liable for statements that the advertiser has not approved and that go beyond the endorser’s own experience.

For affiliates, the practical side is the program the advertiser must run. The FAQ says a network devoted to health products may need more supervision than a fashion network. It lists four elements: tell members what they can and cannot say, instruct them on disclosures, search periodically for what they say, and act on problems. Expect a health brand to send you an approved claims list and to check your pages. The brand-side detail is in monitoring affiliate ads for GLP-1 brands.

FDA limits by category

FDA’s limits depend on what the product is, and affiliate copy can change that in some categories.

Supplements. FDA says it does not have the authority to approve dietary supplements before they are marketed, and that it generally does not approve supplement claims or other labeling before use. A product sold as a supplement but presented, explicitly or implicitly, for the treatment, prevention or cure of a specific disease meets the definition of a drug. FDA also says it considers advertising when evaluating a product’s intended use, so an affiliate’s page can matter.

OTC. FDA and the FTC split work along labeling and advertising lines. Affiliate copy is advertising, so FTC substantiation rules lead, and the label sets the outer limit.

Devices and wearables. FDA issued a revised General Wellness policy on January 6, 2026. It says certain noninvasive products that estimate physiologic values, such as heart rate variability, may be treated as general wellness products if the outputs are intended solely for wellness. They must not be intended for diagnosis, cure or treatment of a disease, and must not prompt specific clinical action. The policy says a product is not a general wellness product if its labeling or advertising refers to specific diseases or diagnostic thresholds. For an affiliate, that means no disease or diagnosis language in your copy.

Telehealth Rx. FDA’s page for telehealth companies (content current June 15, 2026) says FDA is concerned about telehealth companies promoting compounded drugs, including GLP-1s, with false or misleading claims, and that it has issued warning letters to telehealth companies over such claims. It lists five claims to avoid: branding that implies the telehealth company is the compounder, calling a compounded drug generic or the same as the approved drug, claiming it is FDA-approved or evaluated for safety and effectiveness, calling it clinically proven to give the same result, and claiming it comes from an FDA-approved or FDA-licensed pharmacy or facility. On the last point, FDA’s wording is short: “FDA does not approve or license any facility.” Affiliate copy should not repeat any of the five lines. The detail is in FDA misleading-claims rules for compounded GLP-1.

Platform health policies and tracking limits

Every traffic channel adds its own health rules on top of the federal ones, and those policies change often. Check the channel’s current policy before you build the page or the ad. Our guides cover Meta’s weight-loss ad policy, Google’s healthcare policy and TikTok’s rules for GLP-1 ads. The federal sources on this page were checked on November 2, 2026.

Health data adds a separate limit. In February 2023 the FTC announced its first enforcement action under the Health Breach Notification Rule, against GoodRx. The FTC’s complaint alleged GoodRx shared sensitive health information, including users’ medications and health conditions, with advertising companies and platforms, contrary to its privacy promises. The proposed order carried a $1.5 million civil penalty.

HIPAA’s obligations fall on covered entities and business associates, so the brand you promote may be bound by them even where you are not. HHS’s tracking bulletin says a Texas federal court on June 20, 2024 vacated part of its guidance on unauthenticated public webpages. The bulletin still says that pages where a user schedules an appointment or enters a reason for care may give tracking tools access to PHI. The safe habit for an affiliate is to keep health details out of URLs, parameters and any data you pass to the brand or to ad platforms. Meta’s side is covered in health-data restrictions and tracking.

Seven checks before promoting any health offer

These seven checks work for any health product, and you can run them without us.

1. Confirm the product category. Supplement, OTC, device or telehealth program. The category sets which rules apply.
2. Get the brand’s approved claims list. Use only those claims. The FTC’s monitoring elements start with telling members what they can and cannot say.
3. Put a disclosure next to the link or in the video. “Paid link” beside an affiliate link, and a spoken and on-screen disclosure in video.
4. State typical results, not best results. If you quote a result, get the brand’s typical-results language. “Results not typical” does not fix it.
5. Never name or imply FDA approval for what the FDA has not approved. This covers “FDA-approved pharmacy,” “same as” and “generic” language for compounded products.
6. Check platform policy for the channel you will use. Platform health policy is enforced separately from federal law, so copy that is legal can still be rejected.
7. Keep health details out of URLs and parameters. No conditions, medications or answers to intake questions in anything you pass along.

GLP-1 telehealth, worked through

A GLP-1 telehealth offer is a useful example because all four rule sets apply at once. The affiliate sends visitors who are comparing telehealth providers. The affiliate does not send patients, and the copy must not suggest anyone is eligible for treatment.

Run the page through the matrix. On claims, nothing may suggest a compounded product is the approved drug or has been FDA-approved, and nothing may describe a pharmacy or facility as FDA-licensed, because FDA licenses no facility. On testimonials, a “lost 50 pounds in 6 months” story needs typical-results context the affiliate usually does not have, so ask the brand for approved language or skip the story. On disclosure, mark every affiliate link and every video. On platforms, apply the channel’s weight-loss and health policies before you launch. On data, pass no health details in tracking.

Frequently asked questions

Is “affiliate link” by itself an adequate disclosure?

Probably not, according to the FTC. Consumers might not understand that “affiliate link” means the person who placed it gets paid for purchases made through it. A “buy now” button is not adequate either.

Is “paid link” by itself an adequate disclosure?

The FTC says “paid link” right next to an affiliate link should be an adequate disclosure of the nature of the link.

What about affiliate or network marketing?

The FTC’s guidance applies to affiliate and network marketing, with a section of its FAQ devoted to it. Disclose your commission clearly and conspicuously, close to the recommendation. The same guidance applies to links in reviews on other people’s sites and in social posts.
