Market Truth checks what health product marketing claims against what the regulatory record and the published research actually show. It covers supplements, wellness devices and at-home health tech. One named editor writes everything, no brand pays for coverage, and a negative verdict is a legitimate result rather than a commercial problem.
What is Market Truth?
Market Truth is an independent US publication that puts a health product’s marketing claim next to the evidence behind it, and reports the gap. We cover dietary supplements, wellness devices and at-home health technology. Every page is written by one named editor, sourced to primary documents, and dated.
The site exists because of a structural gap in how health products reach American consumers. A prescription drug must prove safety and effectiveness to the FDA before it is sold. A dietary supplement does not. A medical device cleared through the 510(k) pathway is judged against an older device, not against a placebo. A “general wellness” device is reviewed by nobody at all. None of that is written on the packaging, and almost none of it appears in the search results people read before buying.
Most health writing online is a buying guide with the conclusion written first. This is not that.
Why does another health site need to exist?
Because the ones that rank are structurally unable to publish a negative verdict. We surveyed the top results for common supplement and device questions before starting this site. The pattern was consistent enough to be worth stating plainly.
| Site type | Typical business model | Can it say “this does not work”? |
|---|---|---|
| Affiliate review site | Commission on every product it names | Structurally, no. The verdict is the product. |
| Large health publisher | Advertising plus retail commission | Rarely. Pages end in a purchase link. |
| Hospital or clinic blog | Institutional marketing | Yes, but it will not name a brand or a price. |
| Manufacturer content | Direct product sales | No. |
| Market Truth | None of the above | Yes. “No” is a legitimate finding here. |
We are not claiming the large publishers are dishonest. We are pointing at an incentive. A page that concludes “save your money” earns nothing, so almost nobody writes one. That leaves a real question unanswered for a lot of people, and answering it is the entire purpose of this site.
Who writes Market Truth?
Erin Delaney writes and reviews everything published here. She is a health science journalist, not a physician, and the site says so on every page rather than borrowing authority it does not have. Her background is nine years of consumer reporting on health products and the advertising rules that govern them.
A single named byline is a deliberate choice. Sites in this niche routinely publish under invented medical review boards, stock headshots and titles like “Research Analyst” attached to nobody in particular. If you cannot find out who wrote a health page, that is information about the page.
How does Market Truth make money?
At the time of writing, it does not. There are no advertisements, no sponsored posts, no paid placements and no brand relationships of any kind. No manufacturer has ever seen a page here before publication, and none ever will.
If that changes, it will change visibly. Any referral link will be labelled in the sentence that contains it and disclosed on the disclosure page, and no commercial arrangement will ever be allowed to change a verdict. A page whose conclusion depended on a commission would be worthless, which is the whole problem this site was built to answer.
What is Market Truth’s editorial policy?
Five rules govern everything published here, and they are enforced in that order.
- Primary sources only. A claim is checked against the FDA, the FTC, the NIH Office of Dietary Supplements, USP, NSF, or the peer-reviewed literature. Never against another blog, and never against a manufacturer’s summary of its own study.
- Say where the evidence stops. Most consumer health questions have a partial answer. Reporting a partial answer as a definite one is the most common failure in this field, and we would rather write “nobody has tested this properly” than manufacture confidence.
- Separate the claim from the finding. We quote what the marketing actually says, then report what was actually measured. Those are two different sentences and they get written as two different sentences.
- Date everything. Every page carries a published date and a last-reviewed date, and every source block records when we last opened the source.
- Correct in public. Errors are fixed on the page, marked, and dated. We do not silently edit a page and pretend it always said the new thing.
The full method, including what counts as evidence here and how the evidence hierarchy is applied, is set out on how we research.
What Market Truth is not
Market Truth is not a government agency and is not affiliated with, endorsed by, or acting on behalf of the FDA, the FTC, the NIH, the Office of Dietary Supplements, USP, NSF, or any manufacturer, retailer or trade body. It is not a clinic, a medical practice or a telehealth service.
Nothing published here is medical advice, diagnosis or treatment, and none of it is a substitute for a licensed clinician who knows your history, your medications and your test results. If you are deciding whether a supplement or device is appropriate for a specific condition you have, that decision belongs with your clinician, not with a website. We can tell you what the research found. We cannot tell you what to do about your own health, and we will not pretend otherwise.
