In this brief medical commentary, Dr. Anne Truong explains that vitamin D deficiency undermines the effectiveness of erectile dysfunction (ED) medications through two key physiological pathways. First, a deficiency triggers oxidative stress, leading to a surge in superoxide radicals that diminish nitric oxide availability and damage vascular integrity. Second, recent research indicates that low vitamin D can induce cellular fibrosis in penile tissue, creating scar tissue that directly blunts the response to ED drugs. Together, these mechanisms reduce the therapeutic benefit of ED pills in men with insufficient vitamin D levels.
