Vitamin B12

Vitamin B12, also known as cobalamin, is an essential nutrient vital for the production of red blood cells, DNA synthesis, and proper neurological function. It is primarily found in animal-based foods like meat, dairy, and eggs. Supplements and injections are also available, especially for those on vegan or vegetarian diets. A deficiency in Vitamin B12 can result in anemia, fatigue, and neurological issues.
