Folate isn’t just for expectant moms. New Research shows that a broken-down form of the nutrient can help antidepressants do their job better. Patients who took prescription L-methylfolate along with a daily antidepressant had 50 percent fewer symptoms than those who took the antidepressant alone. “The brain needs L-methylfolate to make and release mood-regulating neurotransmitters such as serotonin, ” explains psychiatrist John Zajecka, M.D., of Ruth University in Chicago. Even better: The stuff has as few side effects as a placebo.
