Several clinical trials have examined whether supplemental folic acid (sometimes in combination with other B-vitamins) reduces the risk of colorectal adenoma in individuals with or without a history of adenoma. Some experts have therefore been concerned that high intakes of folate supplements might mask vitamin B12 deficiency until its neurological consequences become irreversible. Although limited evidence suggests that supplementation with certain forms and doses of folate might be a helpful adjuvant treatment for depressive disorders, more research is needed to confirm these findings. WebThe daily requirement is about 400 ug.
