Enzyte is said to contain: Asian Ginseng Root Extract Grape Seed Extract Epimedium (Horny Goat Weed) Zinc oxide Muira puama Ginkgo biloba Niacin Copper Most of the above ingredients are commonly available as over the counter herbal or dietary supplements, and most have anecdotal reports, but marginal or unproven scientific evidence, of efficacy on various systems in the human body. Several of the herbal ingredients are included only in very low quantities. Yohimbe was previously included in the original formulation of Enzyte, produced until at least 2004.
