What is the main role of vitamin B12?

To help the body absorb calcium
To produce blood cells and maintain nervous system health
To aid in digestion
To promote healthy skin

The correct answer is: To produce blood cells and maintain nervous system health

The primary role of vitamin B12 is to produce blood cells and maintain nervous system health. This vitamin is essential for the synthesis of red blood cells, which are crucial for transporting oxygen throughout the body. A deficiency in vitamin B12 can lead to megaloblastic anemia, where blood cells become larger and less effective. Additionally, vitamin B12 plays a vital role in maintaining the health of the nervous system by assisting in the production of myelin, the protective sheath that surrounds nerves. This contribution is essential for proper nerve function and communication. The other choices focus on different areas of health that are not directly related to the primary functions of vitamin B12. For example, while calcium absorption is important for bone health, it is primarily influenced by vitamin D and not B12. Digestion is supported by a variety of nutrients and enzymes but is not specifically linked to vitamin B12. Healthy skin relies on a range of vitamins and minerals, including some B vitamins, but vitamin B12 is not a direct promoter of skin health in the same way it influences blood and nerve function.
