Vitamin B12, or cobalamin, is an essential water-soluble vitamin that your body cannot produce. It must be obtained through your diet, injections, or oral supplements. If you cannot get enough vitamin B12 through diet alone or have an absorption disorder, then supplements are an easy way to increase your B12 intake.
Vitamin B12 is responsible for numerous bodily functions and benefits your health in various ways, including producing red blood cells, preventing major birth defects, supporting brain and bone health, boosting energy, enhancing mood, and maintaining healthy skin and hair.
How to Use Vitamin B12
Vitamin B12 is found naturally in animal products, although some plant-based milks and grains are fortified with vitamin B12. The recommended daily amount of vitamin B12 is 2.4 mcg, although higher for pregnant or breastfeeding women.
