Vitamin B₁₂, also known as cobalamin, is a water-soluble vitamin involved in the metabolism of every cell of the human body.
Vitamin B12 is an essential vitamin that the body requires to work properly.
It is required for the proper function and development of the brain, nerves, blood cells, and many other parts of the body.
Unfortunately, B12 deficiency is common, especially in the elderly. You’re at risk of deficiency if you don’t get enough from your diet or aren’t able to absorb enough from the food you eat. (1)
