Integrative and functional medicine practices market differently from most clinics. Patients read for months before they book, so the practice website, blog, newsletter, podcast appearances and social posts do most of the persuading. That content sits very close to health claims: what a protocol does, what a test shows, what a supplement supports, what a patient experienced.
This guide explains the federal rules that decide which of those claims you can make, using the Federal Trade Commission’s own guidance, its enforcement actions and Google’s ad policies. It ends with a practical review process you can run on your own site. For how we approach marketing in this field more broadly, see our integrative and functional medicine marketing page.

This is general information based on FTC and Google pages as we read them in October 2026, not legal advice. State medical, chiropractic and naturopathic boards have their own advertising rules, and FDA rules apply to product labels.

The rule in two sentences
The FTC sums up its truth-in-advertising law as two principles: advertising must be truthful and not misleading, and before an ad runs the advertiser must have adequate substantiation for every objective claim it conveys, expressly or by implication. For health benefits and safety, the FTC says that substantiation generally has to be “competent and reliable scientific evidence.”
Three points practice owners often miss:
- It covers services, not just products. Section 12 of the FTC Act makes false advertising unlawful when it is likely to induce the purchase of “food, drugs, devices, services, or cosmetics.” A program, protocol or therapy you sell is covered as much as a bottle on your shelf.
- “Advertising” is broad. The FTC’s Health Products Compliance Guidance defines it to include websites and other digital content, social media, press interviews and other media appearances, seminars, and promotion “indirectly through healthcare practitioners.”
- More than one party can be liable. The same guidance notes the FTC has acted against individual owners and officers, ad agencies, expert endorsers and others who took part in deceptive marketing, not only the company selling the product.
What counts as a claim
The FTC looks at the “net impression” of the whole piece, not single phrases. That includes the headline, the program name, images, charts and patient stories. In the FTC’s words, marketers “can’t suggest benefits, safety, or other characteristics about their product indirectly that they couldn’t claim directly.” What matters is what a reasonable reader takes away, not what you meant.
In this field, implied claims often come from places nobody thinks of as advertising:
- A program name such as a “reversal” or “detox” program for a named disease.
- A blog post on a condition that ends with “book a consult to start healing” next to your protocol.
- Before-and-after lab charts from one patient, with no context.
- A podcast clip on your site in which a provider says a therapy “fixes the root cause” of a disease.
- An ingredient list for a supplement you sell, placed beside a page about a serious condition.
The guidance also says an ad can mislead by what it leaves out. If a benefit only applies to a small group, such as people with a confirmed deficiency, the claim has to say so. If a product or treatment has significant safety risks, those may need to be disclosed too.
What the FTC means by scientific evidence
The FTC defines competent and reliable scientific evidence as tests, analyses, research or studies conducted and evaluated objectively by experts in the relevant field, and generally accepted in that profession to give accurate and reliable results. The guidance then sets out what that usually looks like for health claims:
- Randomized, controlled human trials are “generally the type of substantiation that experts would require for health benefit claims.”
- Observational studies can show an association but do not prove cause, except in limited cases where experts accept them and trials are not feasible.
- Animal and lab (in vitro) studies are background only. Without human trials, the FTC says, they are not enough to support health claims.
- The whole body of evidence counts. You cannot pick the studies that agree with you and ignore the ones that do not. If stronger evidence points the other way, the guidance says even a qualified claim is likely deceptive.
- Quality beats quantity. Many weak studies do not add up to competent and reliable evidence.
Claims about serious disease carry the highest bar. In 2023 the FTC sent a Notice of Penalty Offenses on substantiation to roughly 670 marketers of supplements, OTC drugs, homeopathic products and functional foods. It lists as unlawful, among other things, claiming that a product cures, mitigates or treats a serious disease without at least one well-controlled human clinical trial, and saying a claim is “clinically proven” when it is not.
Patient stories and testimonials
Patient stories are powerful in integrative and functional medicine, and they are where many practices get into trouble. The FTC’s position is plain: a testimonial cannot make a claim you could not make directly. An honest, accurate patient story still implies that the treatment works and will work for the reader, and that implied claim needs scientific support.
- Typical results. Under the FTC Endorsement Guides (16 CFR 255.2(b)), a story about a key outcome will likely be read as what people generally achieve. If it is not, you need to clearly disclose what people can generally expect. The health products guidance adds that “Results not typical” disclaimers do not fix a misleading testimonial.
- Connections. If a patient got a discount, a free visit or anything else for a story or review, that connection has to be disclosed (16 CFR 255.5). The same goes for staff, family and paid experts.
- Reviews. The FTC rule on consumer reviews (16 CFR Part 465) bans fake reviews, reviews conditioned on a positive sentiment and suppressing negative reviews. Our guide to asking for and replying to patient reviews covers this in detail.
- Privacy. If your practice is a HIPAA covered entity, using a patient’s story or photos in marketing generally requires the patient’s written authorization under 45 CFR 164.508. Our med spa website guide explains how that works for photos.
Traditional use, “natural” and disclaimers
Much of this field draws on botanical, homeopathic and traditional practices. The FTC treats claims based on traditional use the same as any other health claim: they need competent and reliable scientific evidence. You may describe a traditional or historic use, but only if the product matches that use (same ingredients, dose, form and purpose), and any health benefit that lacks scientific support must clearly say so, close to the claim. Positive stories or images next to that disclosure can undo it.
Two disclaimers do less than many practices think:
- The supplement label disclaimer. “These statements have not been evaluated by the FDA…” is a label requirement for supplements. The FTC says it does not cure an otherwise deceptive ad, and gives the example of an herbal product advertised to treat diabetes: the disclaimer does not save the claim.
- “FDA” wording. Do not suggest the FDA approved a product or claim when it did not. FDA clearance of a device for one use is not approval for the results you advertise.
Supplements and products sold in the office
If you sell supplements, test kits or devices, the FTC guidance applies to the product pages, emails and handouts you use to sell them, whoever wrote the original copy. Copying a manufacturer’s claims does not move responsibility to the manufacturer. The guidance also warns that handing out articles or study abstracts to promote a specific product can make you responsible for the claims they imply.
If you are paid by a brand (commission, affiliate link, advisory fee) and recommend it, disclose that connection where patients will see it.
Google Ads rules on top of the FTC
Google applies its own policies, which can be stricter than the law. Three matter most here:
- Unreliable claims. Google’s Misrepresentation policy does not allow “unproven claims of cures for incurable medical ailments,” with examples such as “miracle cures” for arthritis, diabetes, Alzheimer’s disease or cancer and “cure-all” products. Testimonials that claim specific results must carry a visible disclaimer that results are not guaranteed and can vary.
- Speculative and experimental treatments. Google does not allow ads for speculative or experimental medical treatments, or for cell and gene therapies, with stem cell therapy and platelet rich plasma (PRP) named as examples. In the US the exception is FDA licensed or approved therapies promoted by the license holder, plus purely educational content.
- Harmful health claims. Content that contradicts authoritative scientific consensus on a current major health crisis, such as anti-vaccine advocacy, is not allowed.
Google also checks the landing page, not only the ad. A compliant ad that sends people to a page full of cure claims can still be disapproved. Our guides to healthcare ad policy basics and Google Ads for practices cover the rest of the healthcare policy.
What enforcement has looked like
These are public FTC cases involving clinicians, not hypotheticals:
- Stem cell clinic, 2018. The FTC settled charges against a California physician (a D.O.) and two companies he ran over advertising that “amniotic stem cell therapy” could treat conditions including Parkinson’s disease, multiple sclerosis, macular degeneration, autism and heart attacks. The FTC said there was no evidence for those claims. The settlement included a payment of $525,000 that the FTC used for consumer refunds.
- Chiropractor, 2021. In the first case under the COVID-19 Consumer Protection Act, the FTC charged a St. Louis chiropractor and his company with marketing vitamin D and zinc products as able to treat or prevent COVID-19, after an earlier FTC warning letter. The FTC said there was no competent and reliable scientific evidence for those claims and sought civil penalties.
- Notices of Penalty Offenses, 2023. The roughly 670 recipients of the substantiation notice were put on notice that they could face civil penalties if their health claims are not properly supported.
A claims review you can run on your own site
- Collect everythingWebsite pages, blog posts, program pages, product pages, email sequences, social profiles, handouts, podcast or video clips on your site, and your ads.
- List every health claimWrite down each benefit, express or implied, including those carried by program names, images, charts and patient stories.
- Match each claim to its evidenceFor each claim, note the human studies that support that exact claim for that exact product, dose or service. If you cannot point to them, the claim has to change.
- Rewrite or removeTurn outcome promises into descriptions of what you do, what a visit involves and what the evidence does and does not show. Remove disease cure or reversal claims you cannot support.
- Check stories and reviewsConfirm each story is typical or carries a clear statement of typical experience, connections are disclosed, and you hold any authorization you need.
- Clinician sign-offHave a provider review every medical statement before it goes live, and record who reviewed it and when.
- Recheck ads and landing pagesCompare each ad and its landing page against Google’s healthcare and misrepresentation policies.
Illustration. A headline to avoid: “Reverse your autoimmune disease at the root cause.” A headline that describes instead of promising: “How our practice approaches autoimmune conditions: what a first visit involves, which tests we may discuss, and how we work alongside your other doctors.” The second tells a careful reader what to expect and makes no outcome claim.
How we handle this for our clients
When we write or edit content for an integrative or functional medicine practice, we explain conditions, tests and the practice’s approach without promising outcomes, keep disease claims out unless the practice can support them with the level of evidence described above, and have the practice’s clinicians review every medical statement before it goes live. We check ads and landing pages against Google’s policies before a campaign starts. See integrative and functional medicine marketing, healthcare SEO and medical website design.
Frequently asked questions
Can we write blog posts about conditions we treat?
Yes. Education about a condition, how your practice approaches it and what a visit involves is the safest and often most useful content. The risk starts when a post says or implies that your treatment produces a specific result. Those claims need competent and reliable scientific evidence, usually human clinical trials.
Can we post a patient’s success story?
You can, with care. The FTC says the story carries an implied claim that the treatment works and that the result is typical, so you need evidence for the claim and a clear statement of what patients can generally expect if the story is not typical. “Results may vary” alone is not enough. If you are a HIPAA covered entity, get the patient’s written authorization first.
Does adding “this is not medical advice” or the FDA disclaimer protect us?
No. The FTC says the supplement label disclaimer does not cure an otherwise deceptive ad, and a general disclaimer does not cancel a specific claim made elsewhere on the page.
Can we mention that a remedy has been used for centuries?
The FTC allows describing traditional use only when your product matches that use and the ad clearly says there is no scientific evidence for any benefit that lacks it. The disclosure has to be near the claim and not undercut by testimonials or images.
Can we run Google Ads for PRP or stem cell treatments?
Generally no. Google’s policy names stem cell therapy and PRP among the cell therapies it does not allow in ads. In the US the exception is FDA licensed or approved therapies promoted by the license holder, and purely educational content.
