Chrysin (5,7-dihydroxyflavone) is an organic chemical compound from the flavonoid group. In nature, it is found in some plants (including Passiflora caerulea, Passiflora incarnata and Oroxylum indicum), fungi (Pleurotus ostreatus), honey and propolis. In vitro study showed it acts as an aromatase inhibitor, and may also stimulate steroidogenesis. Chrysin is also credited with the ability to increase the sensitivity of Leydig cells to stimulate cAMP, which may result in enhanced testosterone synthesis.
Chrysin also has a broad spectrum of health-promoting properties. It has anticancer potential and may increase the effectiveness of conventional chemotherapy. In addition, it favors reducing the activity of the NF-kβ factor and lowering the level of pro-inflammatory compounds, and thus reduces the intensity of inflammation in the body. It also seems to modulate the level of GABA, and thus it has a relaxing and antidepressant effect.
Supplements usually include chrysin extracted from passiflora flowers. Chrysin has gained the name of an effective natural aromatase inhibitor. Due to its properties, it is often added to formulas aimed at reducing the activity of estrogens and preparations aimed at increasing the level of testosterone.
Dosage: no precise dose has been established. The studies proved the safety of doses of 0.5 g to 3 g per day.
