Tribulus terrestris has been used for centuries in ancient Greece, India and Africa to support fertility and rejuvenate the body. Recent scientific studies indicate that, although it actually contains no hormones, Tribulus helps to support healthy hormone production and male reproductive health. Tribulus has been used by some of the world's most elite athletes, but may be used by the recreational athlete as well. Our minimum 45% saponin content makes NOW® Tribulus one of the most potent formulas available.*

What is Tribulus and what is it good for?

Tribulus terrestris is a perennial trailing plant that grows predominantly in India. It has been used for centuries in Indian Ayurvedic medicine as an herbal tonic for sexual dysfunction and certain urinary disorders. Tribulus seems to work by facilitating the absorption of essential fatty acids (EFA), which are used by the liver to manufacture certain hormones. In men, the secretion of leutinizing hormone (LH) from the pituitary gland appears to be increased. In women, it appears to increase secretion of follicle stimulating hormone (FSH) and estradiol. Studies of this herb are ongoing. Herbs currently being studied for similar effects are Maca, a Peruvian perennial that grows in the Andes mountains, and Muira puama, an Amazonian plant.

Tribulus is not the same as horny goat weed, a popular libido-enhancer currently on the market. This herb is called Epimedium (Epimedium grandiflorum).
