Results from a study of 52 men and women with major depressive disorder showed that only 1 of 14 participants with low serum folate levels responded to antidepressant treatment compared with 17 of 38 with normal folate levels [120]. Several important questions about these effects remain, including the dose and timing of folic acid supplementation that might exert tumor-promoting effects and whether this effect is specific to synthetic folic acid or other forms of folate [57].
