Cobalamin
Cobalamin, also known as vitamin B12, is a water-soluble vitamin that plays a crucial role in various bodily functions. It is essential for the formation of red blood cells, neurological function, and DNA synthesis. Cobalamin is not produced by the body and must be obtained from food sources or supplements.
Functions of Cobalamin:
- Red Blood Cell Formation: Cobalamin is necessary for the production of red blood cells. Without an adequate supply of vitamin B12, a type of anemia called megaloblastic anemia can occur.
- Neurological Function: Cobalamin is involved in the maintenance of the nervous system. Deficiency in vitamin B12 can lead to neurological symptoms such as numbness, tingling, and difficulty walking.
- DNA Synthesis: Cobalamin plays a key role in the synthesis of DNA, the genetic material in all cells. It is important for cell division and growth.
Sources of Cobalamin:
Cobalamin is found naturally in animal products such as meat, fish, eggs, and dairy. It is not present in plant-based foods, so vegetarians and vegans may need to obtain vitamin B12 from fortified foods or supplements.
Deficiency and Supplemental Intake:
A deficiency in cobalamin can lead to anemia, neurological problems, and other health issues. Individuals at risk of deficiency include older adults, individuals with gastrointestinal disorders, and strict vegetarians. Supplementation or consumption of fortified foods may be necessary for those at risk of deficiency.
