Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Folate (vitamin B9) has scientific support for its use as an adjunctive treatment in depression, especially in individuals with low folate levels or specific genetic polymorphisms (such as MTHFR mutations) that impair folate metabolism. Multiple clinical studies and meta-analyses suggest that people with depression often have lower folate levels compared to the general population. Low folate status has been associated with poorer response to standard antidepressants and greater severity of depressive symptoms. Supplementing with folate—particularly in the form of L-methylfolate, the bioactive form—has been shown in randomized controlled trials to enhance the efficacy of antidepressant medications in some patients, especially those with treatment-resistant depression or genetic impairments in folate metabolism.

However, the evidence is not universally strong. The benefit appears most pronounced in individuals with documented folate deficiency or specific genetic profiles. For the general population of people with depression, results are mixed, with some studies showing modest benefit and others showing little or no effect. Consequently, clinical guidelines sometimes recommend folate supplementation as an adjunct for certain patients with depression, but it is not considered a first-line treatment. Overall, while folate has a scientific basis for use in depression, particularly as an adjunct in specific subgroups, its efficacy does not reach the level of standard antidepressant therapies.
