This time it's a steroid!

A free steroid!

One that humans evolved over millions of years to use, but are mostly deficient in. It's Vitamin D.

Vitamin D is actually not a vitamin. It's a steroid hormone precursor. And there are credible studies that show that optimal levels of active Vitamin D (50 ng/mL) actually increases athletic performance.

The Vitamin D Council is a great resource for news and discoveries about Vitamin D.
