Proper Name: Folic Acid

Common Name: Vitamin B9

Evidence of Efficacy: statement to the effect of Vitamin B9 deficiency or imbalance plays a role in the symptoms of mood disorders. Observational and experimental studies have shown an association between vitamin B9 and bipolar disorder^{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17}, depression^{18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31,3 2,33 ,34 ,35, 36, 37,3 8,39 ,40, 41,4 2,43 ,44, 45, 46, 47, 48, 49,5 0,5 1,5 2,53, 54,5 5,56 ,57, 58,5 9}, and schizophrenia^{60, 61, 62, 63, 64, 65, 66, 67, 68}.
