What is Icariin and why does the 10% concentration matter?

Icariin is the principal active compound in Epimedium — a prenylflavonoid glycoside and the main marker used to standardize the extract. It is the compound most associated with the traditional uses of Horny Goat Weed.

Why Icariin Matters

At the 10% grade, the extract provides a standardized, economical level of icariin suitable for everyday supplement formulations (capsules, tablets, blends). Higher grades (30%–98%) deliver more icariin per gram for concentrated or specialized products. Note: we supply ingredients only — all health claims must comply with the regulations of your target market. Share your formulation — we advise on the optimal grade.
