The effect if oxidative stress in the brain has been linked to dementia, depression[2, 3] and now suicide attempts. According to a study published in Nutritional Neuroscience, a study of nearly 7000 individuals with mental health diagnoses, those who attempted suicide had significantly lower levels of critical antioxidants than those who did not. Could this study be the beginning of an evidence base supporting the recommendation of anti-oxidant supplementation for depressed patients with suicidal ideation?
