June is Men’s Health Month—a timely reminder to focus on overall well-being, including sexual health and performance. While vitamin D is commonly associated with bone health, it plays a crucial role in several other systems, including those tied to erectile function. Many men may not realize that low levels of this essential nutrient could be affecting their performance and confidence.
Vitamin D supports a wide range of bodily functions, including heart health, immune response and hormone regulation. Increasing evidence links vitamin D deficiency to erectile dysfunction (ED). A 2020 study published in the World Journal of Men’s Health highlighted the connection between low vitamin D levels and ED, suggesting that maintaining adequate levels is vital for sexual health.
For men experiencing ED—or those simply aiming to stay proactive—checking vitamin D levels may be worthwhile. This is especially important for men over 40, those carrying extra weight or those that spend little time outdoors.
Vitamin D may also help support healthy testosterone levels and vascular flexibility, both of which are crucial for sexual and cardiovascular health. Some clinical trials suggest that men with diabetes that supplemented with vitamin D experienced improved blood vessel function.
Unfortunately, vitamin D deficiency is widespread. Nearly one-half of adults over 50 have inadequate levels, increasing the risk for health issues linked to ED, such as high blood pressure and arterial plaque buildup.
Men are encouraged to talk with their healthcare provider about vitamin D screening. A simple blood test can offer valuable insights—and may lead to improvements in energy, sexual performance and overall well-being.
