Chrysin Info And Products
Block Estrogen, Increase Testosterone

1. What is it and where does it come from?

Chrysin is a naturally occurring isoflavone chemically extracted from the plant Passiflora coerulea.
Honeycomb and Aronia Melanocarpa also contains small amounts. High quality Chrysin supplement is available
from organic Herb Inc.

2. What does it do and what scientific studies give evidence to support this?

Scientific studies show that flavones (primarily chrysin) may exert a wide variety of powerful effects.
Specifically, studies done in Europe show that after supplementing with chrysin blood serum levels of testosterone went up a whopping 30%! How does it work? There are two major hormones in both guys and gals: testosterone and estrogen. Testosterone is dominant in guys and estrogen is dominant in gals.
But interestingly, estrogen seems to be a signal to the pituitary gland in the brain. Based on estrogen levels, the pituitary turns on or off testosterone production. The higher the estrogen levels, the lower the amounts of testosterone will be produced. This is where chrysin comes in! Chrysin basically reduces estrogen levels by cutting down on its conversion from testosterone

Benefits of Chrysin

Chrysin possesses potent anti-inflammation and anti-oxidation properties. Chrysin is able to stimulate nitric oxide release from endothelial cells leading to vascular cGMP accumulation and subsequent endothelium dependent vascular relaxation. Chrysin stimulated nitric oxide release is calcium independent and possibly mediated via PI3-kinase. 

Chrysin is able to suppress liposacharide-induced COX-2 protein and mRNA expression in a dose-dependent manner. Nuclear factor for IL-6 has been identified as responsible for the chrysin -mediated COX-2 downregulation.

There are claims that chrysin stimulates the release of testosterone. Since chrysin is available as an herbal supplement, some users, for instance body builders, are taking chrysin with the hope of raising testosterone levels or stimulating testosterone production. One study listed below did not find chrysin supplementation leads to any significant increase in testosterone production.
