Vitamin B12 Overview

Vitamin B12 Vitamin B12, also known as cobalamin, is a water-soluble vitamin crucial for several bodily functions. It plays a pivotal role in the formation of red blood cells, aiding in the prevention of anemia. Vitamin B12 is essential for maintaining a healthy nervous system and proper brain function, as it is involved in the synthesis of myelin, the protective sheath around nerve fibers. This vitamin is primarily found in animal-based foods such as meat, fish, dairy products, and eggs, making it important for vegetarians and vegans to consider supplementation. A deficiency in vitamin B12 can lead to neurological issues, fatigue, and cognitive impairment.
