B12
Red blood nutrient
B12 is a vitamin essential for nerve function, red blood cell formation, and DNA synthesis.
Found naturally in animal products—meat, fish, eggs, dairy—it's the nutrient most likely to be deficient in vegan diets.
My doctor said my fatigue was from low B12.
Also called cobalamin.
The full form is vitamin B12.
