This paper presents a synopsis of the Institute of Medicine (IOM) Dietary Reference Intakes (DRIs) for folate and the recommended folic acid intake to reduce the risk of neural tube defects. Estimated intake of folic acid is presented and total folate intake is compared to the DRI. Vitamin B12 DRIs are highlighted in addition to the IOM recommendation for crystalline vitamin B12 intake specifically for individuals ≥57 years of age. Recently reported evidence of vitamin B12 inadequacy in the aging segment of the U.S. population will be addressed.
