Description:
Vitamin B12, vitamin B12 or vitamin B-12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins. It is normally involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid synthesis and energy production.

Usage:
1.Vitamin B12 works closely with folic acid ( vitamin B9) and pyridoxine ( vitamin B6) to convert food into energy. It also works with these B vitamins to protect your heart by removing homocysteine from the blood. Too much homocysteine in the system can damage arterial walls and contribute to the development of atherosclerosis, a condition that often leads to early heart attack.
2.Taking supplemental Vitamin B12 is very safe. There have been no reports of toxic reactions in those exceeding the RDA and, in fact, it is almost impossible to overdose on B12 since the excess is simply excreted. However, it is important to note that large doses of vitamin C can actually destroy cobalamin. Therefore, you should not ingest these supplements at the same time.

Main function:
* promote the formation and red blood cells regeneration, prevent anemia
* maintenance nervous system health
* promote children's growth, stomachic
* fatty acid metabolism, make fat, carbohydrate, protein is the proper use of the body
* eliminate irritability, focus your attention, improve memory and balance
