Vitamin B12 is a water-soluble vitamin that plays a key role in the body. It is found in animal products such as meat, fish, eggs, and dairy. This vitamin is also known as cobalamin and is part of the B-vitamin family, which is vital for various bodily functions.
Vitamin B12 is important for health because it helps prevent a type of anemia called megaloblastic anemia, where the body does not produce enough healthy red blood cells. It also supports the nervous system, helping to maintain healthy nerve cells and the production of DNA. A deficiency in vitamin B12 can lead to fatigue, weakness, and neurological issues.
In the body, vitamin B12 is involved in several critical functions. It aids in the formation of red blood cells, which carry oxygen throughout the body. Additionally, it is essential for the synthesis of myelin, the protective sheath around nerves. Proper levels of vitamin B12 are necessary for maintaining mental clarity and overall cognitive function.
For those who follow a vegetarian or vegan diet, it is important to monitor vitamin B12 intake, as it is primarily found in animal sources. Supplements or fortified foods may be necessary to ensure adequate levels of this vital nutrient.
