Introduction to Vitamin B12
Vitamin B12, also known as cobalamin, is an essential nutrient that plays a crucial role in various bodily functions, including red blood cell formation, neurological function, and DNA synthesis. Unlike many other vitamins, B12 is primarily found in animal products, making it essential for those following a vegetarian or vegan diet to find alternative sources or consider supplementation.
Why is Vitamin B12 Important?
Vitamin B12 is crucial for:
- Energy Production: It helps convert carbohydrates into usable glucose, which fuels energy production.
- Neurological Function: B12 supports nerve health and helps maintain myelin, the protective sheath around nerves.
- Red Blood Cell Formation: It aids in the formation of red blood cells, which carry oxygen throughout the body.
