Very safe: Folic acid is very safe with no known toxicity. There is only one reason some authorities advise limiting Folic Acid to 1 mg/day which had nothing to do with Folic Acid being hazardous but due to the fact that high doses can cover up evidence of B12 deficiency. If you are not deficient in B12 then high doses are quite safe- see http://lpi.Oregonstate.Edu/infocenter/vitamins/fa/.
