Beneficial Effects

Vitamin B12 is important for normal blood, cells, and nerves. Folic acid is needed to form healthy cells, especially red blood cells. Folic acid helps your body build healthy cells and turn food into energy.
Vitamin B12, also called cobalamin, is one of 8 B vitamins. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which is used to produce energy. These B vitamins, often referred to as B complex vitamins, also help the body use fats and protein. B complex vitamins are needed for healthy skin, hair, eyes, and liver. They also help the nervous system function properly.
