A flavonoid compound found in bee pollen and propolis. Can boost testosterone when injected into testicles; otherwise isn't absorbed at all. Unless better absorption arises, chrysin remains a pretty interesting colon cancer preventative agent that does not boost testosterone.

Chrysin is a bioflavonoid compound found in high levels in propolis and in honey.
Chrysin is most well known for being a testosterone boosting plant compound, although this seems to be a misleading claim. While it has very good mechanisms of action that would lead to the conclusion that it could boost testosterone (as in, it sensitizes the testicles to produce more testosterone and inhibits the conversion of testosterone to estrogen) these both occur at significantly higher oral doses than are seen with oral supplementation. Chrysin appears to be poorly absorbed, and even then it is readily metabolized resulting in insufficient levels in the blood and testes to exert these beneficial effects.

Due to the poor bioavailability, the standard supplemental doses of chrysin (400-3,000mg) appear to be pretty much ineffective. Although enhancing absorption can theoretically aid in chryin's effects, this has not yet been demonstrated and thus supplementation of chrysin cannot be recommended for systemic purposes.
A supplemental dose of 400mg chrysin should be sufficient for intestinal related issues.
