Vitamins and minerals to maintain health
Vitamins and mineral supplements are important both in preventing deficiency states as well as in preventing diseases. Most diseases resulting from vitamin deficiencies such as scurvy (vitamin C deficiency), night blindness (vitamin A deficiency), and beriberi (thiamine deficiency) occur mainly in third-world countries and are almost nonexistent in the United States. But certain special populations in the United States can develop vitamin or mineral deficiencies, and thus require dietary supplements. For example,
- severely malnourished alcoholics can develop nerve damage from thiamine deficiency;
- individuals lacking sun exposure can develop bone disease from vitamin D deficiency;
- pernicious anemia is a condition associated with nerve damage, which can result from vitamin B12 deficiency; and
- people with celiac sprue can also develop vitamin deficiencies, as well as iron deficiency.

For these special populations, vitamin supplements are important to prevent these deficiencies.
Vitamin 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 the developing fetus in pregnant women.
