What is Vitamin В12  and Top 14 Foods Rich in it.

Vitamin В12, commonly known as cobalamin, plays an essential part in the proper operating of the nervous system and the brain. It has a positive effect on lipid metabolism, stimulates growth and reduces cholesterol level. Cobalamin is used for generating DNA as well as metabolizing carbohydrates and fats.

A minor quantity of vitamin B12 can be produced in intestinal tract and the rest is consumed with the animal food. Even though B12 is a water-soluble vitamin, its significant quantities can be accumulated in a healthy liver.

A daily suggested value of vitamin B12 is 2.4mcg for adults, 2.6mcg for pregnant women and 2.8mcg for lactating women. Increased doses are often prescribed to athletes. People over 50 must consume more cobalamin-containing foods or take vitamin B12 supplements.

Vitamin B12 is a steady nutrient that is hardly destroyed in the processes of storing and cooking. Boiling does the biggest damage to cobalamin-containing foods. This cooking technique destroys from 10 to 50% of vitamin B12. That is why nutritionists usually suggest steaming. In case boiling is inevitable, it should be as short as possible.

Interaction Of Vitamin В12 With Other Nutrients

As a part of B complex, vitamin B12 is very sensitive to availability of other B vitamins in the body. For example, lack of vitamins B6 and B9 can lead to vitamin B12 deficiency.

Deficiency Of Vitamin В12

Most of people who regularly eat dairy products, fish and meat have no need to worry about vitamin B12 deficiency. The only groups under the risk are strict vegans and ovo-lacto vegetarians. The first ones do not consume most of the cobalamin-containing foods. However, they may have some sources of vitamin B12 stored in their bodies, if they have been eating meat and milk before. Ovo-lacto vegetarians include eggs and dairy products to their diet. That decreases the risks of vitamin B12 deficiency for them.

Another issue connected to cobalamin deficiency is a disorder called pernicious anemia. It affects people over 50 and affects vitamin B12 absorption. Approximately 10-30% of elderly people have this disorder. The indications of vitamin B12 deficiency include nervousness, weakness, dizziness, poor appetite, pale skin with a yellowish tone. Lasting deficiency can cause serious complications with nervous system, including diseases like mania and psychoses.

It is not possible to eat so much food containing vitamin B12 to cause dietary toxicity.
