Testing focused on products made with yohimbe and/or epimedium (“horny goat weed”), two popular ingredients found in natural remedies for sexual dysfunction. Some products also contained and were tested for L-arginine, an amino acid involved in blood flow (the focus of a separate Product Review of L-Arginine Supplements).
It is estimated that over 30% of men suffer from erectile dysfunction and over 40% of women live with a lack of libido or have trouble achieving orgasm. “It’s no wonder that many people are willing to try supplements that promise to improve sexual functioning and fulfillment,” says Tod Cooperman, MD, ConsumerLab.com’s president. As discussed in the report, natural ingredients can help, to a limited degree, with erectile dysfunction and, possibly, libido.
