Vitamin B12

About

Vitamin B12, also known as cobalamin, is a water-soluble vitamin essential for various bodily functions. It plays a crucial role in maintaining healthy nerve cells and is necessary for the formation of red blood cells. Vitamin B12 is involved in DNA synthesis and helps regulate the nervous system. It is naturally found in animal products like meat, fish, and dairy but can also be obtained through supplements or fortified foods. Vitamin B12 deficiency can lead to conditions such as megaloblastic anemia, characterized by fatigue and weakness. It is particularly important for individuals with restricted diets, such as vegans, and those with gastrointestinal disorders. Vitamin B12 comes in several forms, including cyanocobalamin, methylcobalamin, and hydroxocobalamin, each serving different purposes. While cyanocobalamin is commonly used in supplements, methylcobalamin is an active form in the body. Hydroxocobalamin is used to treat cyanide poisoning. Maintaining adequate levels of vitamin B12 is vital for overall health and preventing related deficiencies.
