While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

Written by the company

Supplements that tell you what the evidence actually says. Most supplement marketing works by leaving things out. We take the opposite approach: every claim we make is tied to a named study, and every study's limitations are stated alongside its findings. If the research is small, old or uncontrolled, we say so. Our first product is TUDCA, a bile acid supplement. We chose it because the human research on it is genuinely interesting and almost universally misrepresented by the people selling it. We publish the underlying evidence in full, including the trials that did not go our way. A case that cannot survive its own caveats is not worth making. Based in the UK.

Tudca vs. ox bile and milk thistle

I had tried ox bile and milk thistle before but they didn't really help with my gallstones. Now, I've been using Dr Primal's Tudca for 3 months, and I feel like my digestion has massively improved. I can finally have cheese and steak without stomach pain.
