Questions people ask
Members Only
Is Dr. Berg a good brand?
We grade products, not brands, and we sell none. Of the 2 Dr. Berg products we graded, 2 are Tier 3 (Reviewed). 2 are top-ranked for the goals they were graded for. Each product's grade, the studies behind it and its label are on its own page.
Which Dr. Berg products have the strongest evidence?
By our grades: Natural Vitamin B1+ Allithiamine with B Complex Blend (Tier 3, graded for energy); Gallbladder Formula Extra Strength (Tier 3, graded for gallbladder and fat digestion). A product's grade is for the goal it was graded for, at the dose on its label.
How does Reverse Age Lab grade Dr. Berg 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 Dr. Berg makes, tests or sells its products, and we are not affiliated with Dr. Berg.
Can I take Dr. Berg 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. Dr. Berg is a trademark of its owner; Reverse Age Lab is not affiliated with it and sells no supplements. How we grade →
