Chrysin is categorized as a polyphenol, classified as a flavonoid within the flavone subclass. It is prominently found in propolis and bee pollen. Often associated with potential testosterone-boosting properties, its practicality for bodybuilding purposes remains limited due to poor absorption and rapid metabolism when orally supplemented. Extracted from the blue passion flower and also reported in Indian trumpet flower, chrysin was once believed to be an effective aromatase inhibitor. However, current evidence suggests limited efficacy in impacting estrogen levels in animals or humans. While studies have explored its antioxidant, antispasmodic, anxiolytic, and anti-inflammatory activities, the potential testosterone-enhancing effects of chrysin for athletes remain inconclusive.
