Vitamins C, A, and B are supplements that can be taken with iron to improve energy and reduce tiredness and fatigue.

When you have iron-deficiency anemia, low iron leads to a lack of red blood cells to carry oxygen to various parts of your body. Sometimes a gastrointestinal (GI) disorder causes this type of anemia.

Milk can interfere with the absorption of some vitamins, minerals, and medications, which may make the supplements or medications less effective.
