Vitamin D is being touted on many websites as the latest “cure” for erectile dysfunction.
The idea is based on the fact that Vitamin D may increase testosterone. However, the association between Vitamin D and testosterone has not been proven. In fact, studies have yielded conflicting results.
A study conducted on 20111 concluded that “vitamin D supplementation might increase testosterone levels”
However, another study in 20182 found that “Vitamin D treatment had no effect on serum TT levels in middle-aged healthy men with low TT levels.”
The majority of cases of ED are not caused by a testosterone deficiency, and studies have shown that raising testosterone levels usually does not improve erectile dysfunction, even in men with Low T (See Does Low Testosterone Cause Erectile Dysfunction?).
If you’d like to be sure your getting enough Vitamin D for general health reasons, the best way to achieve this is by getting plenty of sunlight, and eating foods that are rich in vitamin D (fortified milk or juice, fatty fish, cheese, and egg yolks.
