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.
This is also the case if you don't get the recommended amount of iron every day, which is 18 milligrams for women and 8 milligrams for men. You can always take your iron supplement with water, but if you want a tastier beverage, try orange juice. The vitamin C in orange juice and other citrus juices will help you better absorb the iron from your supplement.
