What Supplements Actually Help with Erectile Dysfunction?

Several supplements show evidence for improving erectile dysfunction, though effects are generally modest. L-arginine (3-5 grams daily) may enhance blood flow by increasing nitric oxide production, with studies showing 31% improvement rates. Panax ginseng demonstrates consistent benefits, with research indicating 60% of men experience better erections after 8 weeks of supplementation. DHEA (50mg daily) can help men with low testosterone levels. Other promising options include citrulline, horny goat weed, and zinc for those with deficiencies. However, supplements work best for mild ED and should complement, not replace, lifestyle changes like exercise and stress reduction.
