Vitamin D and Erectile Health: A Practical Guide for Thai Men
A growing body of research suggests vitamin D may influence erectile function, especially for men with low vitamin D levels. While erectile dysfunction has many causes, improving vitamin D status could support vascular and hormonal health that underpins sexual performance. In Thailand, where abundant sunshine meets urban living, clinicians are examining how sun exposure and supplementation fit into broader health strategies.
Erectile dysfunction refers to the persistent difficulty in achieving or sustaining an erection sufficient for sexual activity. Vascular health is a key factor, alongside stress and metabolic conditions. Vitamin D supports endothelial function and blood vessel health, which are essential for penile blood flow. Deficiency can be linked to inflammation and oxidative stress that may impair performance. Global studies show men with low vitamin D often report poorer erectile function, with moderate improvements observed after supplementation in deficient individuals. Thai clinicians note higher ED risk among patients with obesity, diabetes, or limited sun exposure.
