Mechanism of action

The active compounds in Tribulus terrestris, particularly saponins, are believed to stimulate nitric oxide synthase and increase nitric oxide availability in endothelial cells. This leads to vasodilation and improved blood flow. The extract has also been studied for potential effects on testosterone levels and sexual function, though evidence remains mixed.
