The Importance Of Vitamin B12

Storing And Absorbing B12

The health of the digestive system is just as important as getting vitamin B12 because the absorbability of B12 is dependent on the health of the digestive system. However, according to research done in 2007 by the scientific journal Experimental Biology and Medicine, vitamin B12 is difficult to absorb. Healthy adults only absorb and use up to fifty percent of the vitamin B12 they consume.
