won the attention of athletes. Some claim that it may be bodybuilders` best kept secret. Containing an active component named 5,7- dihydroxyflavone, Chrysin is a naturally occurring flavonoid. It is the most potent natural flavonoid found in some plants, such as Passiflora caerula, Prunus domestica, and Pinus asistata. Some researchers claim that there is a small amount of Chrysin in honeycomb.Functions of Chrysin:
The conversion phenomenon of testosterone into estradiol is called “aromatization”. It is accelerated by an enzyme named aromatase. Chrysin is a potent aromatase inhibitor, which blocks the conversion of testosterone into estradiol. Subsequently, the level of testosterone increases. Another possible mechanism by which it works is through “lifting negative feedback”, that is, your body starts to produce more testosterone in response to low levels of estrogen resulted from inhibited aromatization. Some supplements manufacturers also claim anti-viral and anti-inflammatory effects for Chrysin.
Chrysin and Athletes:
The ability of Chrysin to elevate the levels of testosterone was sufficient evidence for 
athletes to use it. Based on reports from European athletes, Chrysin increases the levels of testosterone up to 20-30% within a few weeks.
There is no standard dosage for Chrysin, but as a dietary supplement, 500 to 1000 mg per day can be used. Some power athletes may use up to 3000 mg daily. Athletes should divide the daily dosage, taking one part in the morning and another part about one hour before a workout. For best results, Chrysin can be used along with other testosterone enhancers including Tribulus terrestris, zinc, and DHEA. Two ingredients of Tribulus terrestris, daidzein and genistein, do the same work that Chrysin does.
It is recommended that people with liver and kidney diseases do not take Chrysin.
