L-Arginine, Tribulus and Horny Goat Weed: The Last Three
L-arginine, tribulus and horny goat weed round out the blend: an amino acid and two herbs from different parts of the world.
L-arginine
L-arginine is an amino acid, a building block of protein. The body also uses it to make nitric oxide, which helps blood vessels relax and widen. That is why it often shows up in circulation formulas.* Meat, fish, dairy, nuts and seeds all supply it.
Tribulus terrestris
Tribulus is a low vine with spiny fruits, nicknamed puncture vine. Herbal traditions in India and China have used the fruit for a long time.
Horny goat weed
Horny goat weed is the common name for Epimedium, a leafy herb of Asia. In China it is called yin yang huo. A popular legend about a goat herder gave it the name.
Three different types
- L-arginine: a nutrient made by fermentation.
- Tribulus: a fruit from a creeping vine.
- Horny goat weed: leaves from a woodland herb.
