Chrysin
Studied for limiting aromatase conversion of testosterone to estrogen.
Mechanism
Chrysin is a flavonoid studied for inhibiting aromatase, the enzyme that converts testosterone into estrogen. Limiting that conversion is theorized to help preserve a healthier testosterone-to-estrogen ratio.
What the evidence shows
Laboratory research supports Chrysin's aromatase-inhibiting mechanism, but human bioavailability is notably poor when taken orally — a limitation that sublingual delivery is specifically intended to help address, though direct human trial data remains limited.
Safety notes
Generally well tolerated. Consult a doctor before use if you have a hormone-sensitive condition.
