We've finally done it. We've been collating research on supplements and nutrition for over two years, and as of this post, we have 17,069 citations in our database.

At the end of the day, we care about answering one question: What does a supplement do?

And today we finally solve that problem. We've replaced the confusing and cumbersome "Human Trials Database" with a "Human Effect Matrix."

For every supplement in our database, a handy table will tell you what effect each supplement has and how noticeable that effect is.

Does Supplement X help with Y? Now you'll know.

Creatine? It has a minor effect in increasing your testosterone, but a strong effect in increasing your power output. What about fish oil? It has actually has a notable effect in decreasing depression!

Best of all, the Human Effect Matrix isn't on the supplement pages only. They are also on the effect pages themselves. Want to know which supplements impact inflammation? Done! Do any supplements help you add muscle? Now you know. (Spoiler: they all have, at most, a minor effect).

What we've done is removed all the mysticism, hyperbole, and marketing-speak used to talk about supplements. It's all tabulated and organized for your perusal, and it's all backed with citations with human-studies.

To get you going, here are a few popular and a few interesting supplements:
