Risk of suicide, suicide attempt, and suicidal ideation among people with vitamin D deficiency: a systematic review and meta-analysis.

Summary: Could a lack of Vitamin D be linked to suicidal thoughts or behaviors? A recent major study analyzed data from over 515,000 people across 13 different studies to find out. The researchers found that people struggling with suicidal behaviors had significantly lower levels of Vitamin D in their blood compared to healthy individuals. While the study showed a trend suggesting that Vitamin D deficiency might increase the risk of suicide attempts, the statistics weren't strong enough to prove a direct cause-and-effect relationship. However, the link is clear enough that researchers suggest checking Vitamin D levels could be a useful part of suicide prevention strategies.
