Horny goat weed (Epimedium) is a flowering plant used in traditional Chinese wellness practices, valued for its content of a compound called icariin.
Icariin is the most studied active compound in the plant, and formulas are often standardized to a specific icariin content for consistency.
In VigorHorse, horny goat weed extract rounds out the formula's proprietary blend alongside the other seven ingredients.
Where it fits in VigorHorse: Horny Goat Weed Extract (Icariin) is one of eight ingredients in the 82 mg proprietary blend. See how it's positioned to work on our how it works page.
