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.
Most people respond well to taking iron supplements, which are available in capsules. Some people with very low iron levels may need intravenous iron. Ideally, you should take iron supplements on an empty stomach because food can decrease the amount of iron your body absorbs. Taking iron supplements with foods or drinks that have vitamin C will help your body absorb the iron. Be sure to take only the recommended dose of iron.
