Nutrilite supplements, graded by the human studies
We graded 2 Nutrilite products against the human studies of their ingredients, the dose on each label and what buyers say in their reviews. Each grade belongs to the product and the goal it was graded for: we do not grade how Nutrilite makes, tests or sells its products, and we sell no supplements. Educational, not medical advice.

Questions people ask
Members Only
Is Nutrilite a good brand?
We grade products, not brands, and we sell none. Of the 2 Nutrilite products we graded, 1 is Tier 3 (Reviewed) and 1 is Tier 4 (Emerging). None is top-ranked for its goal yet. Each product's grade, the studies behind it and its label are on its own page.
Which Nutrilite products have the strongest evidence?
By our grades: Truvivity (Tier 3, graded for circulation); Stress Relief Probiotic (Tier 4, graded for gut bacteria balance). A product's grade is for the goal it was graded for, at the dose on its label.
How does Reverse Age Lab grade Nutrilite products?
Each product is graded for a goal on the human studies of its ingredients at the dose on its label, what buyers say in their reviews and what our panel of ten biohackers has said. The grade belongs to the product. We do not grade how Nutrilite makes, tests or sells its products, and we are not affiliated with Nutrilite.
Can I take Nutrilite supplements with my meds?
Some supplements can interact with meds. Members have every product checked against the meds in their Health Profile before it joins their protocol.
Educational, not medical advice. Grades come from human studies on PubMed, the dose on each label, store reviews we read ourselves and our biohacker panel, and are updated as new studies arrive. Nutrilite is a trademark of its owner; Reverse Age Lab is not affiliated with it and sells no supplements. How we grade →
