Chrysin
1. What is it and
where does it come from?
Chrysin is a naturally occurring isoflavone chemically extracted from the plant
Passiflora coerulea. Honeycomb also contains small amounts. High quality Chrysin
supplement is available from Bodybuilding.com.
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 this 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--duh! 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.
3. Who needs it and what are some symptoms of deficiency?
Today's bodybuilders and competitive athletes are always looking for ways to
boost their natural testosterone levels. Of coarse there's DHEA, Tribulus
terrastis, and androstenedione (to name a few), which supply raw materials for
the production of testosterone. Now there's another way! Our bodies naturally
convert some amounts of testosterone into estrogen (aromatization), a process
which accelerates as testosterone levels go up. Chrysin works by minimizing this
conversion! Chrysin is the "anti-aromatization" if you will. This is
great news for those who want to enhance their muscle building ability!
Furthermore, according to the July '98 Ironman magazine, "bodybuilders
using testosterone boosters today worry a lot less about gynecomastia and hair
loss if they're stacking chrysin." Because chrysin is not an essential
nutrient, it is not associated with deficiency.
4. How much should be taken? Are there any side effects?
European Olympic athletes report 1-3 grams of chrysin per day is a safe and
effective dose. Follow the directions and dosages on the bottles below. For best
results, it is recommended to take one half one hour before working out and the
other half at bedtime. With proper supplementation, there have been no reported
side effects.
