When is the best time to take iron? In most cases, the best time to take iron supplements is about one hour before or two hours after meals. Iron supplements are best taken with water on an empty stomach. There is a long list of foods, such as coffee, tea or milk, which interfere with the absorption of ferrous iron.
Like calcium, iron is somewhat temperamental. Nausea is one of the most common side effects of iron supplements. But while taking iron with food can reduce the GI side effects, food also can reduce the absorption of iron by an estimated 40 to 50 percent. Iron needs to be taken separately from calcium, soy, and zinc, all of which can interfere with iron absorption.
