Can I take 1000 mg of folic acid?

The established Tolerable Upper Intake Level for folic acid in adults is 1,000 micrograms (1 mg) per day. Exceeding this amount is not generally recommended and can carry significant risks, particularly related to the masking of a vitamin B12 deficiency. A daily intake of 1000 mg (which is 1000 times the upper limit) is far beyond safe levels and should only be undertaken under direct medical supervision for specific conditions.
