I’m healthy, happily married (34 years)–and not very hard anymore, even with Viagra. At the health food store, they have a good dozen supplements that claim to boost male sexual energy and performance with ingredients like ginseng, ginkgo, maca, and yohimbe. Do these products work? Or are they a rip-off?

    Male potency supplements are not necessarily a rip-off, but they may or may not work for you. There’s some decent research to show that all the medicinal herbs you mentioned have some pro-sexual effects. High doses of ginseng help men with erection problems. Ginkgo has resolved sex problems in people suffering sexual side effects from antidepressants. A couple small studies suggest that maca boosts men’s sexual arousal. And the bark of the West African yohimbe tree contains a compound (yohimbine) that is FDA-approved for treatment of erectile dysfunction.

    That said, these herbs produce their sexual benefits ONLY at specific doses–and many male potency supplements contain much less than the clinically effective doses. Of course, there can be a substantial placebo effect with purported sex stimulants. If you believe the product will help you, it very well might. But if you want to maximize your chances of benefit, I suggest that you take the doses shown to be beneficial in published research.

    ComfortZone is a supplement marketer, hence the promise of safety and efficacy. As I mentioned in my initial reply, herbal potency products may help, but don’t expect miracles. In fact, keep your expectations low.
