Based on the metabolic interactions between folate and vitamin B12, the FNB established a UL for the synthetic forms of folate available in dietary supplements and fortified foods (Table 3) [2]. This polymorphism results in less biologically available 5-MTHF and, thus, reduced methylation potential, leading to elevated homocysteine levels and an increased risk of NTDs [1,3,20,40]. Similarly, a meta-analysis of 13 randomized trials showed no statistically significant effects of folic acid supplementation (median daily dose of 2,000 mcg) over an average treatment period of 5.2 years on overall cancer incidence or the incidence of colorectal, lung, breast, prostate, or other cancers [72].

The authors of a systematic review and meta-analysis of four trials of folic acid (<5,000 mcg/day in two trials; =5,000 mcg/day in two trials) in combination with fluoxetine or other antidepressants in patients with major depressive disorder concluded that less than 5,000 mcg/day folic acid might be beneficial as an adjunct to serotonin reuptake inhibitor (SSRI) therapy [127]. The usual therapeutic dosage in adults and children (regard less of age) is up to 1 mg Another risk involves the use of folic acid to treat a folate deficiency, but because a folate deficiency closely resembles a vitamin B-12 deficiency, if the B- 12 deficiency goes undiagnosed, the treatment can lead to irreversible brain damage. This is when the brain or spinal cord doesnt develop normally. As the initial test, ruling out cobalamin deficiency is very important because deficiency of folic acid and vitamin B12 produce overlapping neurologic manifestations, and both cause megaloblastic anemia, but folate treatment will not improve neurologic abnormalities due to cobalamin deficiency.
