Increase Red Blood Cells, Prevent B12 Deficiency with B12, 5000 mcg In 1948, vitamin B12, or cobalamin, was isolated and identified as the nutritional factor that prevented pernicious anemia, a deadly disease of the red blood cells. B12 is essential for healthy red blood cells and utilization of iron. It also supports formation of myelin, a fatty substance that protects nerves, and production of acetylcholine, a neurotransmitter needed for memory and learning. B12 helps form DNA and RNA, the body's genetic material, and participates in cellular metabolic reactions. In combination with folate and B6, vitamin B12 helps reduce blood levels of homocysteine, a substance that has been linked to heart disease.
Although we don't need large amounts of B12, it is important for good health. Our bodies' ability to absorb B12 reduces with age and may be inadequate in the elderly, and in vegetarians who consume less dietary B12.

Homocysteine accumulation in the body may dramatically increase the risk of heart disease and osteoporosis. Along with folate and B6, Vitamin B12 helps prevent homocysteine buildup, and may thus help prevent heart disease. Vitamin B12 also plays a critical role in energy metabolism, immunity, and nervous system function.
High doses of B12, administered under strict supervision, have produced good results in the treatment of sleep-wake disorders. Melatonin secretion appears to be influenced by vitamin B12, and low levels of melatonin in the elderly may be related to low B12 status. Taking B12 may improve sleep quality, daytime alertness and concentration, and may enhance mood. It may help shift workers and travelers with changing sleep patterns.
NOTE: A balance of all the B vitamins is important, so supplementation with a good B Complex is also recommended.
