Tag: 2 4 mcg

For most adults, the recommended daily allowance (RDA) for vitamin B12 is 2.4 mcg, a crucial nutrient for healthy nerve function, red blood cell formation, and DNA synthesis. Since the body cannot produce it, achieving this intake requires a careful look at dietary sources and, for some, supplementation.

The recommended dietary allowance (RDA) for vitamin B12 for adults is 2.4 mcg per day, according to the National Institutes of Health. However, finding a supplement with this exact low dosage is nearly impossible; instead, most consumers meet this requirement through diet or choose much higher-dose supplements for better absorption.
