Signs of folate deficiency anemia most of the time are subtle. [4] Anemia (macrocytic, megaloblastic anemia) can be a sign of advanced folate deficiency in adults.

[4] Beyond a load dose of 1.1 mg, urinary excretion increased rapidly, so that with a dose of 2.5 mg, urinary output was 800 micrograms for a 24-hour ...
