Micronized flavonoid fraction that strengthens venous tone, reduces capillary permeability, and improves lymphatic drainage. Inhibits prostaglandin and thromboxane synthesis. Used as prescription venotonic in Europe for chronic venous insufficiency and hemorrhoids.
Saw palmetto berry extract contains fatty acids (lauric acid, oleic acid, myristic acid) and phytosterols (beta-sitosterol) that inhibit both isoforms of 5-alpha-reductase (types I and II), reducing conversion of testosterone to dihydrotestosterone (DHT). It also exhibits anti-androgenic activity by competing with DHT at androgen receptor binding sites. Additional mechanisms include: inhibition of cyclooxygenase and 5-lipoxygenase (anti-inflammatory in prostate tissue), induction of apoptosis in prostate epithelial cells, and relaxation of bladder smooth muscle via alpha-1 adrenergic receptor antagonism.
