Vitamin B12, also known as cobalamin, is an essential vitamin that your body needs but cannot produce.
It’s found naturally in animal products, but also added to certain foods and available as an oral supplement or injection.
Vitamin B12 has many roles in your body. It supports the normal function of your nerve cells and is needed for red blood cell formation and DNA synthesis.
For most adults, the recommended daily intake (RDI) is 2.4 mcg, though it’s higher for women who are pregnant or breastfeeding.
Vitamin B12 may benefit your body in impressive ways, such as by boosting your energy, improving your memory and helping prevent heart disease.
Vitamin D is a fat-soluble vitamin. Vitamin D includes vitamins D-1, D-2, and D-3. The body naturally produces vitamin D when it is exposed directly to sunlight. Vitamin D can also be obtained through certain foods and supplements.

You are at risk of developing bone abnormalities such as soft bones (osteomalacia) or fragile bones (osteoporosis) if you don’t have enough vitamin D in your body.
