NIH Office Dietary Supplements iron fact sheet take iron supplement empty stomach food calcium tea coffee

Usually, iron is absorbed best on an empty stomach. Take it with water, ideally 1 hour before food or 2 hours after food.
But if it causes nausea, stomach pain, or heartburn, take it with a small amount of food instead. Regular use is more important than taking it perfectly on an empty stomach.
Avoid taking it at the same time as:
  • Tea or coffee
  • Milk, calcium supplements, or antacids
  • High-fiber cereal or bran
Keep about a 2-hour gap from these. Taking iron with vitamin C or orange juice may help absorption. NIH guidance notes that calcium can interfere with iron absorption and that empty-stomach doses can upset the stomach.
Also follow the timing on your prescription if your clinician gave specific instructions.

NIH calcium supplements calcium carbonate citrate take with food absorption 500 mg

For calcium supplements, it depends on the type:
  • Calcium carbonate: take with a meal. It needs stomach acid for best absorption.
  • Calcium citrate: can be taken with or without food. It may be preferable if you use acid-reducing medicines or get stomach upset.
For either type:
  • Take no more than 500 mg elemental calcium at one time. Split larger daily amounts into two doses.
  • Keep calcium and iron supplements at least 2 hours apart, because calcium reduces iron absorption.
  • If it causes constipation, bloating, or gas, take it with meals, split the dose, drink enough water, or discuss changing to calcium citrate.
MedlinePlus guidance confirms calcium carbonate is best with food, while calcium citrate works on an empty or full stomach.

Yes, you can take an iron tablet and vitamin C tablet together. Vitamin C can help iron absorption.
Best way: take them with water, ideally 1 hour before or 2 hours after food. If iron upsets your stomach, take it with a small snack.
Keep a 2-hour gap from calcium tablets, milk/dairy, tea, coffee, antacids, and multivitamins containing calcium.
You do not necessarily need a separate vitamin C tablet: iron alone also works well for iron-deficiency anemia. A randomized trial found similar improvement with iron alone versus iron plus vitamin C, as reported in this clinical trial.
