Vitamin B12 is one of the most important vitamins for human body functions. It is also responsible for distributing oxygen in the body. If vitamin B12 is low, the organs and tissues do not get the oxygen they need to function properly and this leads to anemia.
Vitamin B12, also known as ‘cobalamin’, comes from animal products such as meat, fish or dairy products. This vitamin also helps make new DNA and red blood cells.
