Anemia is a condition where the blood does not have enough healthy, normal red blood cells. There are many anemias caused by factors not related to nutrition, but nutrient deficiencies can also be the culprit. The most common nutrient deficiencies that result in anemias are deficiencies of iron, folate, vitamin B12, and vitamin B6.
