ADEQUATE INTAKE (AI): The recommended average daily intake level based on observed or experimentally determined approximations or estimates of nutrient intake by a group (or groups) of apparently healthy people that are assumed to be adequate; used when an RDA cannot be determined. RECOMMENDED DIETARY ALLOWANCES (RDA): The average daily dietary nutrient intake level sufficient to meet the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage and gender group (IOM 2006).    

Iron supplements

Your doctor may recommend over-the-counter iron tablets to replenish the iron stores in your body. Your doctor will let you know the correct dose for you. Iron is also available in liquid form for infants and children. To improve the chances that your body will absorb the iron in the tablets, you may be instructed to:
  • Take iron tablets on an empty stomach. If possible, take your iron tablets when your stomach is empty. However, because iron tablets can upset your stomach, you may need to take your iron tablets with meals.
  • Don’t take iron with antacids. Medications that immediately relieve heartburn symptoms can interfere with the absorption of iron. Take iron two hours before or four hours after you take antacids.
  • Take iron tablets with vitamin C. Vitamin C improves the absorption of iron. Your doctor might recommend taking your iron tablets with a glass of orange juice or with a vitamin C supplement.
Iron supplements can cause constipation, so your doctor may also recommend a stool softener. Iron may turn your stools black, which is a harmless side effect. Iron deficiency can’t be corrected overnight. You may need to take iron supplements for several months or longer to replenish your iron reserves. Generally, you’ll start to feel better after a week or so of treatment. Ask your doctor when to have your blood rechecked to measure your iron levels. To be sure that your iron reserves are replenished, you may need to take iron supplements for a year or more.

Preparing for your appointment

Make an appointment with your doctor if you have any signs and symptoms that worry you. If you’re diagnosed with iron deficiency anemia, you may need tests to look for a source of blood loss, including tests to examine your gastrointestinal tract. Here’s some information to help you get ready for your appointment, and what to expect from your doctor.

What you can do

  • Write down any symptoms you’re experiencing, including any that may seem unrelated to the reason for which you scheduled the appointment.
  • Write down key personal information, including any major stresses or recent life changes.
  • Make a list of all medications, vitamins or supplements you’re taking.
  • Write down questions to ask your doctor.

  • What’s the most likely cause of my symptoms?
  • Are there other possible causes for my symptoms?
  • Is my condition likely temporary or long lasting?
  • What treatment do you recommend?
  • Are there any alternatives to the primary approach that you’re suggesting?
  • I have another health condition. How can I best manage these conditions together?
  • Are there any dietary restrictions that I need to follow?
  • Are there any brochures or other printed material that I can take with me? What websites do you recommend?
In addition to the questions that you’ve prepared to ask your doctor, don’t hesitate to ask questions during your appointment.

  • When did you begin experiencing symptoms?
