Welli Labs review: is it legit?

Live Transparency score 10/100* Checked Oct 15, 2026. Visit wellilabs.com

Our findings in brief

In short: We could complete only 1 of our 6 checks on Welli Labs, so its 10/100 mostly reflects what we couldn't check, not what it hides.

We haven't lab-tested anything from Welli Labs, so this covers public evidence only, not product quality. As of Oct 15, 2026:

What's missing or unverified
