Vitamins supplements to prevent diseases
Vitamin supplements are used to prevent deficiencies and also to prevent diseases. Certain vitamin supplements (such as folic acid, vitamin B6, and B12) have been used to lower blood levels of homocysteine, which may help prevent heart attacks. Folic acid fortification in cereals and vitamin supplements has been found to decrease the risk of birth defects in women of childbearing age.
