For Dr. Bryan Chung, Examine.com is the repository resource for nutritional supplement information

Examine.com has become THE repository resource for nutritional supplement information. Most other similar databases fail at what they’re good at, which is being accessible and being comprehensive. Their frequent updates stay on top of the literature as it evolves. Examine.com gives me an excellent overview of the body of work, which helps me filter and refine my search strategy when I’m looking up supplements that I get asked about that I’ve never heard of. The Human Effect Matrix provides interpretation that is lacking in every other supplement database in the world. Most people don’t have the time or interest to develop high-level expertise, but need somewhere to turn to to make informed decisions about their supplements. That information is at Examine.com.

Dr. Bryan Chung, MSc in Rehabilitation Science, MD, PhD

Dr. Yoni Freedhoff sees in Examine.com a massive and helpful undertaking

It’s insufficient to simply rely on belief, conjecture or internet advice to determine if supplements are right for you. Instead you need to rely on research. With Examine.com’s guide, not only will you find their summary of the research, but also links to the original papers should you want to do your own due diligence. Truly a massive and helpful undertaking.
