Answer

Answer

Although more studies are needed, a report by Lewis et al suggested that low serum docosahexaenoic acid (DHA) levels may be a risk factor for suicide. The authors studied active-duty US military personnel and found that the risk of suicide death was 14% higher per standard deviation of lower DHA percentage. Among men, the risk of suicide death was 62% greater with low serum DHA status. [90]
