Vitamin B12 is a water-soluble vitamin that is very important to the formation of blood cells, cell metabolism, nerve function, and DNA production. Also, it helps prevent megaloblastic anemia.
1. Recommended daily dose
The amount of vitamin B12 you should take will depend on your age:
- Babies should get between 0.4 and 0.5 mcg during their first year of life, and 0.9 mcg until they’re 3.
- Children 3-8 should get 1.2 mcg, and 8-13 should take 1.8 mcg.

- Women that are pregnant or breastfeeding should get between 2.6 and 2.8 mcg respectively.
2. How your body absorbs vitamin B12
By eating foods rich in vitamin B12, your stomach acid separates it from the proteins it’s attached to. Then, cobalamin combines with a stomach protein to absorb into your body.
