Uses

What is vitamin B12 used for?

Vitamin B12, also known as cyanocobalamin, is one of many types of B vitamins that are needed by the body. Vitamin B12 is important in the synthesis of new red blood cells, nerve cell health, and releasing energy from food. It also works alongside folic acid.

Vitamin B12 is not made in the human body, so it must be ingested either through food or dietary supplements. A deficiency of B12 may result in anemia.

How should I take vitamin B12?

Vitamin B12 is available as an oral tablet. Many multivitamins contain several types of B vitamins as well as other vitamins and minerals. The oral tablet should be taken by mouth without chewing or crushing it. It is best to take it before a meal.
