Vitamin B12 is an interesting vitamin, because it cannot be found in vegetables or fruits. It is only found in meat and Sauerkraut, because it is produced by a particular genus of bacteria. These bacteria are also in soil, which we cannot eat. In the liver of some animals there are also bacteria, who produce vitamin B12. But why do we need this vitamin?
Vitamin B12 is actually a really important vitamin, as it keeps our blood and nerve cells healthy. It also helps in the production of the genetic material of our cells. With a vitamin B12 deficiency one gets a pale-yellow tinge to the skin, a sore and red tongue, mouth ulcers and pins and needles. As well as one’s walk. One’s sight is more limited and one is more irritatable. Depressions are also an often diagnosed symptom.
A vitamin B12 overdose is impossible, because if you have to much vitamin B12 in your blood, quantities that are not required are excreted. Normally only people who do not eat meat, for example vegetarians or vegans have to take vitamin B12 supplements. Our body stores vitamin B12, which makes a deficiency in the early stages harder to diagnose.
