Is VigRX Plus Effective? The Clinical Evidence

What the one published trial found

Shah et al. (2012) recruited 78 men aged 25 to 50 with mild to moderate erectile dysfunction from clinics in India. Seventy-five completed the study, 39 on VigRX Plus and 36 on placebo. At the end of 12 weeks, the IIEF erectile function score had gone up by an average of 9 points on VigRX Plus, compared with 0.61 on placebo. Gains in desire, orgasm and satisfaction were also reported by the authors. Mostly mild side effects showed up about equally in both groups.

Several limits apply. The trial was small and short, and no outside team has repeated it. Placebo response was unusually low. Its formula had 11 ingredients, taken as 2 capsules twice a day, whereas the current label shows 8 ingredients at 1 pill twice a day.

Key Ingredients

As of October 2026, the official site names eight ingredients and the sales page gives no amounts:

• Asian red ginseng: a few small ED trials, with pooled evidence described as suggestive but of low quality
• Damiana, muira puama and catuaba bark: backed mostly by traditional use and small uncontrolled studies
• Ginkgo biloba: could raise bleeding risk if you take blood thinners
• Hawthorn berry and saw palmetto: nothing meaningful on sexual function
• Bioperine (black pepper extract): may change how the body handles some drugs

The trial formula also had Tribulus, Cuscuta and epimedium, which no longer appear on the current list.

Our Verdict

Healthy men with mild erection concerns who'd like a herbal product backed by at least one published placebo-controlled trial are the likeliest fit. Keep expectations modest. If you take blood thinners, diabetes medicines or heart medicines, ask a doctor first. Ongoing erection problems can also be an early sign of heart disease, so raise them with a doctor.
