From the Guidelines
No, there is no scientific evidence that beetroot supplements increase penile length. Despite some internet claims, no credible medical studies have demonstrated that beetroot or its compounds can enlarge the penis. Beetroot does contain nitrates that convert to nitric oxide in the body, which can improve blood flow and potentially help with erectile function by relaxing blood vessels, as discussed in the context of erectile dysfunction management 1. However, improved blood flow does not translate to increased penile size or length. The adult penis size is determined primarily by genetics and hormonal factors during puberty, and cannot be permanently increased through supplements, herbs, or non-surgical interventions. Some key points to consider:
- Erectile dysfunction is a common disorder that affects all age groups, especially people with advanced age, diabetes, vascular diseases, psychiatric disorders, and possibly hypogonadism 1.
- The management of erectile dysfunction typically involves pharmacologic treatment, such as PDE-5 inhibitors, which can improve erectile function but do not affect penile length 1.
- If you're concerned about sexual health, focus instead on overall cardiovascular health, maintaining a healthy weight, regular exercise, and avoiding smoking and excessive alcohol, as these factors can positively impact erectile function.
- For persistent concerns about sexual health, consulting with a healthcare provider is the most appropriate course of action, as they can provide personalized advice and treatment options based on individual needs and health status.
From the Research
Evidence for Beet Root Supplements and Penile Length
- There is no direct evidence that beet root supplements increase penile length 2, 3, 4, 5, 6.
- However, beet root is a rich source of nitrates, which can increase nitric oxide production in the body 3.
- Nitric oxide is a key factor involved in initiating and maintaining an erection, and impaired nitric oxide bioactivity is a major pathogenic mechanism of erectile dysfunction 2, 4, 6.
- A plant-based diet that includes whole plant foods like beet root may improve endothelial function and increase nitric oxide concentrations, which could potentially enhance penile erection 3.
- Topical therapies that include nitric oxide donors have been shown to be effective in treating erectile dysfunction, but there is no evidence that beet root supplements have a similar effect 5.
