Vitamin B12 is not just useful - it is vital. This is the only one nutrient, containing cobalt - a trace element necessary for our health. And to tell you about all the intricacies and processes which involve this vitamin, it is necessary to use the obscure chemical, and biological terms, but not do without it ...

In conjunction with vitamin C, folate and pantothenic acid, vitamin B12 is actively involved in the metabolism of proteins, fats and carbohydrates. It helps the molecules to produce choline, folic acid - one of the most important chemical transmitter of nerve impulses. One of the main problems is the production of vitamin B12 methionine - a substance that is in our psyche, "conducting" such feelings as love, kindness, sense of joy.

The most recent study of this amazing material has shown that lack of vitamin B12 leads to a lack of carnitine (also called kvazivitaminom), a substance that catches the blood fat molecules and sends them to the mitochondria - "power plants" of cells, where they are oxidized to give energy throughout the body .Without carnitine content of decomposition products in the blood rises as oil remains untreated. You understand that any good it does not ...
And, perhaps most importantly - Vitamin B12 in conjunction with other substances triggers the basic life process - the synthesis of ribonucleic and deoxyribonucleic acids. And they, as you may remember from school biology lessons are protein substances that make up the cell nucleus and which contain all the genetic information.
It's amazing that the substance which we need in the amount of 3 g (microscopic dose!), Has an active effect on the body.
Vitamin B12 - water soluble. Our bodies produce it on their own can not, but the substance is well-
accumulates in the liver, kidneys, lungs and spleen. The number of accumulated vitamin is small and has no toxic effects (as can happen with a fat-soluble vitamins A, D, E and K).
Vitamin B12 is found only in foods of animal origin! His greatest amount found in liver, kidney, heart, and oysters.

Vitamin B12 is quite stable at high temperatures, with the usual preparation, he collapses slightly, but you have to be very "polite" to milk - long boiling at all, not only deprives him of all the vitamins, but generally reduces its nutritional value. As milk porridge cooked by our parents? Milk is put on the fire, brought to a boil, poured boiling grits and all until ready for a half hour, no less. And you need to do the opposite - in a little water to cook grits (a bit of water so as not to wash away - remember the 70% of vitamin B6 in a merged broth), add milk and boil once - and you're done!
