Every sentence on a regen service page or product sheet is a claim. Claims substantiation is the work of proving each one before it goes live. The FTC has a written standard for what counts as proof. Most practices and product companies have never read it. This post puts that standard in plain words and gives you five steps to run on Monday.
TLDR: The FTC expects every objective claim to be truthful, not misleading, and backed by evidence before it runs. For health claims, that evidence is usually competent and reliable scientific evidence, a defined term. Claims substantiation is a five-step routine: write the claim as the reader hears it, list the evidence you hold, match evidence to claim, rewrite down, and keep the file. Read on for the standard in plain words, the mistakes we see most, and one service page sentence rebuilt.
Important Note
This article is for educational purposes only and does not constitute legal, medical, or regulatory advice. Marketing strategies discussed should be reviewed by qualified legal counsel before implementation, particularly regarding FDA, FTC, and state-specific advertising regulations. Regen Portal is a marketing and consulting company, not a law firm. Nothing here implies FDA approval of any product or any use. Most cell, tissue and exosome products marketed to patients are not FDA approved, and the few cell-based products the FDA has approved are approved only for specific labeled indications. Nothing here promises a marketing or business outcome. Regulations change and enforcement varies by state. Confirm current requirements with qualified legal and compliance counsel before you act on anything you read here.
When we ask a practice or a vendor what the evidence is behind a sentence, the answer is usually vendor materials. Sometimes it is a certificate of analysis or a public clinical trial. Often it is not much at all. That is not a character flaw. Nobody taught this industry what proof looks like.
The FTC did write it down. Few turn it into a routine. This post does that, with five steps for claims substantiation, the mistakes we see most, and one service page sentence taken apart and rebuilt.
What the FTC Means by Claims Substantiation
Claims substantiation means holding enough evidence for a claim before you publish it, not after someone asks. The FTC rule has two parts. Advertising must be truthful and not misleading. And advertisers must have adequate substantiation for all objective claims, express or implied, before the ad runs. Both parts sit in the FTC’s Health Products Compliance Guidance.
Three words in that rule do most of the work. Objective means a claim a reader takes as fact. Implied means the claim the reader hears even if you never typed it. Before means the evidence exists on the day the page goes live.
For health claims, the guidance names the level of proof: competent and reliable scientific evidence. That means tests, analyses, research, or studies run and judged in an objective way by qualified experts. The methods must be ones the field accepts as giving accurate and reliable results. For claims about health benefits, the guidance says this will generally mean randomized, controlled human clinical testing. It sets no fixed number of studies.
The guidance also says what does not count. Anecdotes, consumer surveys, and what a practitioner sees in patients are generally not enough on their own. That last one matters, because so much of this industry’s language starts in the treatment room.
One more rule shapes the rest. The FTC reads an ad the way a reasonable consumer reads it, as a whole, images and headlines included. If a sentence can be read two reasonable ways, you have to back up both.
That is the standard. Now for why regen marketing so often falls short of it.
Why Regen Marketing Drifts Past Its Evidence
Most unsupported claims in regen marketing were never written on purpose. They drift in one word at a time, from “being studied for” to “helps” to “treats,” usually in a subheading nobody thinks of as copy. Each edit felt small. The net impression moved a long way.
The second source is the supply chain. Reps routinely say things to clinic owners that are not compliant, and that is normal in this industry. We have watched that language travel from the rep’s pitch into the clinic’s own ads, superlatives included. The clinic never checked, because the rep sounded sure.
The product side has the same problem. When a product company hands us a deck or a website to review, we flag three things first. Claims that are not compliant, wording too complex for the buyer, and weak graphics. The traffic light framework sorts the language before it goes out, but only if someone runs it.
Add the FDA layer and the stakes climb. The FDA’s consumer alert on regenerative medicine products is dated April 2024. It warns that many of these products are marketed illegally and have not been shown to be safe or effective. It also says there are no FDA-approved exosome products. The FDA has approved a small number of cell-based products, each for a specific labeled indication only. A page that implies otherwise carries an FDA problem and an FTC problem in one sentence. Minimally manipulated claims do not help either.
The fix is a routine, not a rewrite of your whole site. Here it is.
The Five Steps of Claims Substantiation Before You Publish
The five steps take a claim from draft to defensible. Run them on every new page, ad, caption, email, and deck.
Step 1: Write the Claim the Way the Reader Hears It
Write down what a reader will take away, not what your lawyer would parse. A patient reads “supports joint health” as a promise about their knee. A photo of a runner next to a product name makes its own promise. The FTC judges the net impression, so that is the claim you have to prove.
Do this for every element on the page: headline, subheading, image, caption, product name, and testimonial. Write each implied claim in one plain sentence. That list is your claims inventory. The rest of the routine runs on it.
Step 2: List the Evidence You Actually Hold
List what you have, not what the supplier said exists. Ask for the documents and put them in one folder. The usual items look like this:
- The certificate of analysis (CoA) for the lot, with what it tests for.
- The supplier’s published studies, with the product, dose, and population used.
- Any peer-reviewed research on the same product, not a similar one.
- The product’s regulatory status as the supplier states it, in writing.
If the supplier cannot produce an item, write “none” next to that line. That word will matter in step 4.
Step 3: Match the Evidence to the Claim
Each piece of evidence supports one kind of statement, and only that kind. A CoA says what is in the vial and which tests the lot passed. It says nothing about what happens in a patient. A study on a different product, a different dose, or animals does not carry over to yours.
The table below pairs common evidence with the claim it can support. Two terms first: a product statement describes what the product is and how it was tested, and an outcome statement describes what happens to a patient.
| Evidence you hold | Supports | Does not support |
|---|---|---|
| Certificate of analysis | Product statements: identity, sterility testing, lot records | Any outcome statement |
| Supplier brochure or one-pager | Nothing on its own | Any claim at all |
| Study on a different product or in animals | Context about the field, labeled as such | Any claim about your product |
| Randomized controlled trial on your product | The outcome, dose, and population it tested. FDA status is a separate question for counsel | Anything broader or stronger than it tested |
| Your own patient observations | A description of what the practice offers | Any effect or outcome claim |
Most claims lists come back with a lot of the right-hand column, and that is the point of the exercise.
Step 4: Rewrite the Claim Down to What the Evidence Supports
Rewrite until every sentence sits on top of a document in your folder. Outcome language with no human trial behind it becomes product language: what the product is, how the practice uses it, and the research status. A do-not-use line such as “treats knee arthritis” becomes a plain line about one option discussed in a consultation. “Clinically proven” comes out unless you can hand someone the trial.
Two traps sit here. A disclaimer does not rescue a claim. The FTC’s Endorsement Guides Q&A says an endorsement cannot make a claim the marketer could not legally make. A line saying results may vary does not take the place of proof. And a testimonial is still a claim. If a patient video says the pain went away, you need proof that this is the expected result, or a clear statement of what is.
Reviews carry their own rulebook, and we covered the FTC endorsement rules for reviews on their own. Treat them as part of the list.
Step 5: Keep the File
Save the claims list, the evidence, the match, and the rewrite in one place, dated. That file is what you hand to counsel if a letter arrives. Add a line for every claim you decided not to make, and why.
Read a few FDA warning letters or FTC actions and the pattern is clear. The question is not only what you said. It is what you had when you said it. A dated file answers that in one email. It is also the record we build first in a marketing compliance review, because the rest depends on it.
Those five steps catch most claims substantiation problems. The rest come from a short list of habits.
Common Claims Substantiation Mistakes We See
The most common mistake is offering the supplier’s brochure as evidence. A brochure is a claim, not proof of one. When the answer to “what stands behind this sentence” is a glossy PDF, the real answer is nothing.
The second is pointing to a competitor’s page. “They say it, so we can” is not a standard the FTC recognizes. Copying their claim copies their exposure.
Third, using a study on a different product. The FTC guidance asks whether the ingredient, dose, formulation, outcome, and population in the study match yours. If any of those differ, the study is context, not proof.
Fourth, treating “FDA registered” as a credential. Registering an establishment is a listing step. It is not a review of the product, and it is not approval. Used as a credential, “FDA registered” implies an approval the FDA did not give. Stating the plain fact of registration is different.
Fifth, letting reps write the copy by accident. The pitch that sold you the product was not written to the FTC standard. Run it through the five steps before it goes on your site. Building authority without overclaiming starts with owning your own words.
Here is what the five steps look like on one sentence.
One Service Page Sentence, the Evidence, and the Rewrite
Picture a pain practice in a mid-sized city that added an exosome product last spring. The service page headline calls it exosome therapy and says it regenerates damaged joints and restores an active life. Do not use that sentence. Here is why.
Step 1. The reader hears three claims. The product rebuilds joint tissue, it works for joint damage in general, and it returns people to full activity. The word “therapy” adds a fourth: this is an established treatment. All four are on the page.
Step 2. The practice pulls its folder. It holds a supplier one-pager and a CoA showing particle count and a sterility result. It also holds a printout of a small animal study on a different exosome product. The supplier’s written regulatory status is missing, so that line reads “none.”
Step 3. The CoA supports product statements: what the lot was tested for and that it came with records. The animal study on another product supports nothing about this product in people. The one-pager is a claim, not evidence. No document in the folder supports any of the four claims the reader heard.
Step 4. The rewrite drops every outcome, and it drops the offer too. The page becomes an education page. It says what exosomes are, that research on them is early, and that the FDA has not approved any exosome product. It names no product and invites no consult about exosomes. Less exciting, but true, sourced, and specific.
Step 5. The practice saves the headline, the folder, the match, and the rewrite with the date. It adds one line: no regeneration claim made, because no human evidence on this product is held. Counsel and the next content writer now see that file first.
Counsel decides whether that rewrite is right for that practice in that state. The five steps got it to the point where counsel has something to decide.
Frequently Asked Questions
What Does Claims Substantiation Mean in Marketing?
Claims substantiation means having enough evidence for an objective claim before you publish it. The FTC judges the net impression a reasonable consumer takes from the whole ad. For health benefit claims, the expected evidence is competent and reliable scientific evidence, which generally means randomized, controlled human testing.
Does a Certificate of Analysis Count as Substantiation?
It counts for product statements only. A CoA shows what a lot was tested for and the results. So it can back a sentence about identity, sterility testing, or lot records. It cannot back a sentence about what the product does in a patient. That match is step 3.
Can a Disclaimer Fix an Unsupported Claim?
No. Under the FTC’s endorsement guidance, a line about results varying does not take the place of evidence. If an ad or a testimonial shows a result, the advertiser needs proof that the result is the expected one, or a clear statement of what is. Rewrite the claim instead.
Is a Supplier’s Study Enough Proof?
Only if it matches. The FTC guidance asks whether the product, dose, outcome, and population in the study line up with your product and your claim. A study on a similar product, a different dose, or animals gives you context, not proof. Ask the supplier for research on the exact product, and file the answer either way.
Do Testimonials Need Claims Substantiation?
Yes. An endorsement cannot make a claim the marketer could not make directly. So a patient story that describes an outcome is treated as an outcome claim by the advertiser. Add the material connection disclosure if the patient received anything of value. Then run the story through the same five steps.
Key Takeaways
- The FTC expects every objective claim, express or implied, to be backed by evidence before it runs.
- For health benefit claims, that proof is competent and reliable scientific evidence, generally randomized, controlled human testing.
- Anecdotes, patient stories, and what a practitioner sees in patients are generally not enough on their own.
- Claims substantiation is five steps: write the claim as heard, list the evidence, match it, rewrite down, keep the file.
- A CoA supports product statements, not outcomes, and a brochure supports nothing on its own.
Your Next Step
Most practices and product companies we meet have never run a claims inventory. Regen Portal builds that inventory as the first step of every compliance engagement, page by page, with the evidence file next to it. Start with a free audit and find out where your pages stand before a reviewer tells you.
PS: Send us one service page or one product one-pager and we will run a free claims substantiation audit on it.
