Vitamin B12 - Everything you need to know

In the following, we will tell you everything you need to know about vitamin B12. Among other things, we clarify what benefits vitamin B12 can have for you or how much you should generally take. Did you know that vitamin B12 is important for the formation of red blood cells?

What is vitamin B12?

Like vitamin C, vitamin B12 belongs to the group of water-soluble vitamins. Moreover, vitamin B12, also known as cobalamin, is the only vitamin that the body can store for several years, especially in the liver. However, a so-called intrinsic factor is required for the absorption of vitamin B12. Simply put, this is a special protein that is formed in the stomach lining of humans.

What foods contain vitamin B12?

Everyone can absorb vitamin B12 through their diet. Meat, fish, seafood, dairy products and eggs are considered rich in vitamin B12. As you can see, especially foods of animal origin have a high vitamin B12 content. In a normal balanced diet, the vitamin B12 content is actually covered. However, the supply of vitamin B12 is problematic, especially for vegans, which is why the DGE (German Nutrition Society) recommends regular supplementation of vitamin B12 for vegans.

Our One Bear A DAY Vitamins and our Trust Your GUT Vitamins also contain vitamin B12.

What are the benefits of taking vitamin B12?

Many people do not know how important vitamin B12 actually is because the focus is often on other vitamins. Vitamin B12 is very important for cell division and differentiation, for the formation of red blood cells, for protein metabolism and for the development of nerve cells, especially in the spinal cord. Reportedly, a high injected concentration of vitamin B12 helps boost metabolism. However, there is no scientific evidence to support this.
