Vitamin B12 (cyanocobalamin)

Vitamin B12 or cyanocobalamin.
It is one of the most important because it is essential for numerous reactions of synthesis.

Functions or properties of vitamin B12:
* - Antianaemic. Energy donor. Involved in the formation and maturation of red blood cells and involved in the utilization and absorption of iron.
* - Constructivism. It promotes and facilitates the integration of amino acids in proteins.
* - Protector of the liver. Favors the formation of choline and methionine (for skin problems).
* - Neurotrophic. Nutrition nerves.
* - Reduces the risk of polio paralysis, thus serving as background therapy.
* - Collaborate in the absorption of iron and folic acid in the synthesis of the hill.
* - Help correct DNA replication by DNA polymerase.
* - Helps regulate sleep, a dose of 3 mgrs. It helps the development of melatonin in the pineal gland.
* - Aids in the treatment of tinnitus or tinnitus.
* - Supports the formation of myelin

Vitamin B12 is necessary for the protection of neurons, protects the brain from the effects of glutamate, nitric oxide, hypoglycemia, hypoxia.

Glutamate and nitric oxide induce lesions in Alzheimer's and Parkinson's. Myelin is created and maintained by methylation reactions, which depend on vitamin B12. The methyl form promotes nerve regeneration and slows the progression of neurodegenerative diseases. Therefore, it is important to use as treatment of neuropathies.

Sources of vitamin B12
It is found primarily in animal products (cheese, egg yolk, oily fish and some undercooked).
