A recent study conducted by researchers from the Veterans Affairs’ Center of Excellence for Suicide Prevention and the Johns Hopkins Bloomberg School of Public Health has found a correlation between taking vitamin D supplements and a lower risk of suicide attempts and self-harm among U.S. veterans. Examining 1.3 million veterans over an eight-year period, the researchers found that those taking vitamin D3 supplements had a 45% lower risk of suicide attempts and self-harm, and those taking vitamin D2 had a 48% lower risk. The risk was even lower for veterans with the lowest levels of vitamin D in their blood before taking any supplements, with a reduction of 64% when taking vitamin D3, and 58% when taking vitamin D2. Black veterans also saw an even greater reduction in risk with a 64% lower risk when taking vitamin D3 and 58% lower risk when taking vitamin D2. The study’s authors suggest that those considering taking vitamin D should speak to their doctor about the best dosage for them, as it is possible to take too much. They also recommend looking for high-quality brands and ingredients, such as U.S. Pharmacopeia (USP).

While this study did not investigate the reasons behind the link between vitamin D and reducing suicide and self-harm risks, it does provide evidence that taking vitamin D supplements may be beneficial. Further research is needed to understand the effects of taking different doses and to investigate potential drug interactions, nutrient absorption, and recommended doses for different blood levels. The study’s authors suggest that those with concerns about their vitamin D levels should consider asking their doctor for a test.
