Vitamin B12 is an essential vitamin found in foods such as meat, fish, and dairy. It can also be made in a lab and is often taken with other B vitamins.
Vitamin B12 is required for the function and development of many parts of the body, including the brain, nerves, and blood cells. Methylcobalamin is the active form of vitamin B12. Cyanocobalamin, which must be processed by the body into the active form, is the most common type used in supplements.
People commonly use vitamin B12 for vitamin B12 deficiency, cyanide poisoning, and high levels of homocysteine in the blood. It is also used for canker sores, cataracts, Alzheimer disease, osteoporosis, fatigue, and many other conditions.
Vitamin B12 (cobalamin)
Vitamin B12, also known as cobalamin, is an essential nutrient that plays a crucial role in maintaining our overall health and well-being.

While it is necessary for various bodily functions, a deficiency in vitamin B12 can lead to several health complications.
Vitamin B12 (Methylcobalamin)
Methylcobalamin is an active form of vitamin B12 that is important for brain health, nerve function, and red blood cell production. It can be obtained from food sources like meat and dairy or taken as a dietary supplement. Methylcobalamin is one specific, naturally occurring form of vitamin B12 that is active in the body. Methylcobalamin is often considered more bioavailable than other forms, such as cyanocobalamin, which is synthetic and needs to be converted by the body to become active.
