Vitamin B12 – Unleash the Power From Within

Sharing is caring!

     Vitamin B12 is the energy vitamin.  It stimulates the body’s usage of protein, fats, and carbohydrates. Vitamin B12 is essential for the metabolism of nerve tissue and necessary for the health of the entire nervous system. It nourishes the myelin sheaths over the nerves which maintains the normal electrical conductivity through the nerves. Vitamin B12 also helps iron function better and is important for the synthesis of DNA and RNA.  B12 stimulates growth and appetite in children.  B12 is needed for the formation of red blood cells along with iron, folic acid, copper, protein, vitamin C and B6. Vitamin B12 along with B6 and folate have an important role in controlling the level of homocysteine in the bloodstream (elevated homocysteine is associated with circulatory problems). B12 is also required for acetylcholine production in the brain for memory and learning.

     Vitamin B12 (cobalamin) is a water-soluble red vitamin and is essential for health. It is a complex molecule which contains cobalt, carbon, oxygen, phosphorous and nitrogen. Vitamin B12 is needed in much smaller amounts than the other B vitamins (3-4 mcg). A mucoprotein enzyme produced by the stomach along with hydrochloric acid is needed for B12 absorption. B12 is stored in the body with the highest concentration found in the liver, heart, kidney, pancreas, brain, testes, blood, and bone marrow. About 5 mcg circulates daily between the digestive tract and the liver.
