[Used for] 2 Stars Schizophrenia and High Homocysteine (Folic Acid, Vitamin B12) Take folic acid (2 mg), vitamin B6 (25 mg), and vitamin B12 (400 mcg) daily [Why] 
People with schizophrenia who have high homocysteine levels may improve symptoms by supplementing with folic acid, vitamin B6, and vitamin B12. In another double-blind study, daily supplementation with folic acid (2 mg), vitamin B6 (25 mg), and vitamin B12 (400 mcg) for three months improved symptoms of schizophrenia compared with a placebo.107 All of the participants in this study had elevated blood levels of homocysteine, which can be decreased by taking these three B vitamins. Based on this study, it would seem reasonable to measure homocysteine levels in people with schizophrenia and, if they are elevated, to supplement with folic acid, vitamin B6, and vitamin B12.
