The chemical compound chrysin is naturally found in several plants, including two types of passion flowers, chamomile and the Indian trumpetflower. Smalls amounts are also present in the Pleurotus ostreatus, a type of mushroom as well as honeycomb. Extractions of this substance from these various sources are used to medically treat anxiety and inflammation. They are also added to fitness supplements, weightlifting supplements and bodybuilding supplements.
Individuals who use it as a bodybuilding supplement do so because in vitro studies show it to be an effective anti-aromatase inhibitor. The liver produces aromatase. It plays a role in converting testosterone and androstenedione into estrone and estradiol, which are estrogens. This conversion takes place in the brain, liver and, fat tissue.
Inhibiting the function of aromatase lowers estrogen levels and maintains higher levels of testosterone. Production of this hormone in males starts to decline usually between the ages of 30 and 40. This is why older males who want to remain youthful are looking for ways to suppress the production of estrogen and raise testosterone levels.
Lower testosterone levels are caused by a variety of factors. An increase in aromatase enzyme activity is one of them. Aromatase depletes available testosterone and increases circulating estrogen levels. The brain reacts to the estrogen by decreasing production of testosterone. This negative feedback loop leads to an imbalance in sex hormone ratios.
Elevated levels of estrogen also result in higher amounts of sex hormone binding globulin, or SHBG, in the system. SHBG readily binds to testosterone making it unavailable. The imbalance between the sex hormones leads to increased body fat and muscle loss in addition to decreased strength and energy.
Supplementing with testosterone can restore the normal balance of sex hormones. Bodybuilders do this to improve strength and restore muscle mass. When excessive aromatization causes the imbalance, the desired results are achieved by inhibiting the action of aromatase.
Because chrysin is water insoluble, the intestine does not readily absorb it and it takes large doses to see its effects on testosterone levels. Some studies show that the effect is stronger when taken with piperine but the dosage must still be high. Many bodybuilders prefer to use chrysin cream instead. In this form, the chemical is effective in dosages of one-tenth of what it takes when ingested orally. The chrysin in creams bypasses the stomach and liver, minimizing degradation and making it more readily available.
