Vitamin B12: Importance, Adequate Intake, and Deficiency
Vitamin B12, also known as cobalamin, is one of the essential nutrients that the body needs to maintain its functions in a healthy way. This vitamin plays a major role in cell growth, DNA synthesis, and blood cell production.
Importance of vitamin B12:
- Stimulating nerve activity: Vitamin B12 plays a critical role in the health of the nervous system, as it contributes to the formation of the myelin sheath that protects nerve fibers.
- Blood formation: It plays a key role in the formation of red blood cells in the blood, thus helping to prevent anemia.
- Role in metabolism: It participates in several essential metabolic processes, including the conversion of folate to its active form.
