Vitamin B12

Vitamin B12, also known as cobalamin, is a water-soluble vitamin essential for various bodily functions. It plays a crucial role in nerve tissue health, brain function, and the production of red blood cells. It is also involved in DNA synthesis and metabolism.

This vitamin is commonly used as a dietary supplement to address deficiencies, which can lead to fatigue, weakness, and neurological issues. It is often taken by individuals with dietary restrictions, such as vegans and vegetarians, as B12 is primarily found in animal products. Older adults and those with certain medical conditions may also benefit from supplementation.
