Vitamin B12 Test (VITAMIN B12)

Vitamin B12 is a water-soluble vitamin that is part of the vitamin B complex.

Vitamin B12, like the other B vitamins, is important for metabolism. It helps in the formation of red blood cells and in the maintenance of the central nervous system. Vitamin B12 is found in eggs, meat, poultry, shellfish, and milk and milk products.

Because vitamin B12 comes primarily from animal products, people who follow a strict vegetarian diet and do not consume eggs or dairy products may require vitamin B12 supplements. (Non-animal sources of vitamin B12 exist but are highly variable in their B12 content, and are therefore unreliable sources.)

Special Preparation: None.
