About Supplement Verdicts

We review direct-to-consumer supplements by reading what the seller actually publishes, then comparing it with published research. That's it. No testing claims, no invented customers.

Why this site exists

Most supplement reviews online repeat the sales page. We checked 701 competitor review snippets ranking in the top three on Bing. Across all of them, 0% stated a price, 1% gave a rating, and 2% mentioned the guarantee terms.

Those are the three things a buyer wants first. So that's where we start.

What we do on every review

• Read the seller's full sales page and order section, and record every price and shipping charge exactly as shown, with the date we checked.
• Look for a Supplement Facts panel. If there isn't one, we say so plainly, because that absence is itself the answer to a lot of questions.
• Compare the named ingredients against published human trials, and cite those trials by their PubMed identifier so you can read them yourself.
• Price the product against named alternatives that do publish their amounts.

What we don't do

We don't take the products. This is desk research, and every review says so. Anyone claiming a personal result from a supplement after a few weeks cannot separate it from ordinary day-to-day variation, so a first-person anecdote would tell you nothing useful.

We don't publish invented customer reviews, stock-photo testimonials or countdown timers. If you've read a few supplement sites you'll know exactly what we mean.

Who writes it

Dana Whitfield is the researcher behind these reviews. Every page carries the date the facts were verified and a note of what changed when we update it.
