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.
Typically, adults need to get between 60 and 120 mg of iron a day. The best way to take the supplement so that you absorb the greatest amount of iron is to take it in two or more doses during the day. Although the supplements work best on an empty stomach, you may want to take them with food so that they don't upset your stomach. 2  You shouldn't take iron supplements with milk, caffeine, antacids, or calcium supplements. 3  These can decrease the amount of iron that is absorbed.
