Vitamin B12, also known as cobalamin, is a water-soluble vitamin that is very important for protein metabolism. It also helps in the formation of red blood cells and contributes to the maintenance of the central nervous system. It also plays an essential role in maintaining normal nerve function and in the production of DNA. This micronutrient, naturally present in foods such as meat, eggs, dairy products and fish, helps to properly care for skin, nails and hair.
Vitamin B12 deficiency can lead to megaloblastic anaemia, which causes symptoms such as muscle weakness, tiredness or fatigue, as well as mood disorders. It is important to consider vitamin B12 supplementation in vegetarian or vegan diets, to try to ensure optimal intake levels and avoid anaemia or weakness. This micronutrient can be found in multivitamin supplements, B-complex supplements and other supplements containing only vitamin B12.
