Vitamin B12 - Blood Cells

Vitamin B12, also known as cobalamin because it contains cobalt, is one of the most crucial vitamins because it helps maintain healthy red blood cells and nerve cells. Young children require B12 for growth purposes. This vitamin is also involved in appetite control. Helping to make DNA is another key factor attributed to B12-vitamin. Vitamin A, Vitamin C and Vitamin E as well as other B vitamins and calcium all help to improve the body's absorption of B12. While contraceptives, sleeping pills and cholesterol lowering drugs can inhibit B12 absorption. It should be noted that the ability to absorb B12-vitamin declines after age 55.

B12 vitamins promote growth, prevent anemia and relieve irritability. A wide variety of problems with fatigue related symptoms are treated with B12 supplements. Vision problems and diabetes may also be helped by B12-vitamin supplements.
