Vitamin B12, also known as cobalamin, is an important water-soluble vitamin.
It plays an essential role in the production of your red blood cells and DNA, as well as the proper functioning of your nervous system.
Vitamin B12 is naturally found in animal foods, including meats, fish, poultry, eggs and dairy. However, it can also be found in products fortified with B12, such as some varieties of bread and plant-based milk.
Unfortunately, B12 deficiency is common, especially in the elderly.
