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.
Iron is absorbed into your bloodstream best if the supplement is taken about an hour before a meal. If, however, you feel queasy after taking iron, having some food in your stomach can help to reduce stomach irritation and feelings of queasiness. So in this case, it may be better for you to take your iron supplement just after a meal. Take the iron preparation exactly as your doctor tells you to. You will be told how much to take and how often to take it. Your dose will also be on the label of the pack to remind you. It is usual to be prescribed between 1-3 doses a day.
