Why Examine.com?

Examine.com started because we were frustrated.

We were frustrated with supplement companies misrepresenting scientific research. We were frustrated with social media “influencers” peddling products they didn’t use themselves. We were frustrated with famous doctors and mainstream media disregarding context to produce sensationalist headlines.

This frustration drove us to create what we seeked and couldn’t find: a 100% independent company that doesn’t sell supplements or even ad space on its website — a company that lives or dies solely by the accuracy and usefulness of its analyses.

Today, the hundreds of free articles on our website are read by millions of visitors each month, and 50,000 people have bought our publications. Medical doctors, dietitians, coaches, and personal trainers entrust their reputation — and the health of their patients, athletes, and clients — to our analyses.

Like the health professionals, each time you purchase any of our publications, you purchase thousands of work hours from a dedicated team of scientists with degrees in public health, exercise science, kinesiology, nutrition, pharmacology, toxicology, microbiology, biophysics, biomedical science, neuroscience, chemistry, and more.
