A traditional botanical (also known as horny goat weed) studied mainly for circulation.
Epimedium sagittatum is a leafy plant with a long history in traditional herbal practice, more commonly known by its nickname: horny goat weed.
Its key compound, icariin, has drawn research interest specifically for its role in supporting healthy blood flow — which is the main reason it earns a spot in circulation-focused formulas.
HorsePeak Gelatin includes Epimedium as part of its six-ingredient blend, not as a stand-alone claim.
