Beta-Sitosterol

Why Do Athletes Use It?*

Some athletes say that beta-sitosterol helps boost resistance to infection.

What Do the Advocates Say?*

A combination of beta-sitosterol (BSS) and BSSG, a related compound, is known to enhance some parts of the immune system in animals and humans. While not proven to prevent infections in athletes, this combination has been shown to prevent the decline in immune function often experienced at the end of an ultramarathon.
