Vitamin B12, Sundown Naturals, 500 mcg, 200 tabs

Vitamin B12, as the name suggests, is part of the vitamin B complex. Like other B vitamins, it is involved in energy metabolism and other  biological processes.

Most B vitamins are not stored in the body, but vitamin B12 is stored in the liver for several years.

Most vitamins B is found in plant and animal foods, but vitamin B12 is found almost exclusively in animal foods. All vitamins have a simple structure, but vitamin B12 is large and complex. Most B vitamins are easily absorbed, but vitamin B12 requires special compounds.

Probably the most important thing to know about vitamin B12   is that if you eat animals foods every day and in the right amount, you are likely to get enough vitamin B12. If you are a vegetarian, you should get extra vitamin B12.

Vitamin B12 is a necessary cofactor for the production of DNA, the genetic material that acts as the basis of all life. This process requires folic acid and vitamin B6,   and failures in any of these nutrients can lead to problems.

The diagnosis of vitamin B12 deficiency often depends on production problems DNA. This phenomenon, called macrocytosis, is often the first clue for doctors to suspect a problem with the vitamin.

Like its partners folic acid and vitamin B6, vitamin B12 is essential in the production of several mediators. In particular, many researchers believe that low levels of vitamin B12 may lead to poor production of serotonin, a neurotransmitter associated with mood control.

Serotonin is a target for drugs that treat depression.

When the level of vitamin B12 in the body becomes very low, damage to the nervous system can occur. The insulation of the sheath of nerve fibers begins to break down, making the path difficult  signals,  reaching the periphery. It starts with tingling in the limbs.
