Iron and calcium are two essential minerals that play important roles in the body. Iron supports the production of red blood cells to transport oxygen, while calcium helps build and maintain strong bones and teeth. To ensure these two minerals do not interfere with each other, we need to know the appropriate times to take iron and calcium to optimize absorption. So, “when is the best time of day to take iron and calcium” Let’s explore the following article!
Interaction Between Iron and Calcium
The body has a relatively similar absorption mechanism for iron and calcium. When supplemented simultaneously, they will compete during absorption in the digestive tract, reducing overall efficiency [1]. Additionally, other substances in food, such as tannins (found in tea), caffeine (in coffee), or large amounts of calcium in milk, can also hinder iron absorption.
When to Take Iron and Calcium During the Day?
When Should You Take Iron?
- Taking Iron Before or After Meals: The ideal time to take iron is one hour before a meal or two hours after a meal. Taking iron on an empty stomach maximizes absorption.
- Foods Affecting Iron Absorption: When supplementing with iron, avoid drinking tea, coffee, or milk at the same time, as these substances reduce absorption capacity.
- Constipation from Iron: Constipation is a common side effect when taking iron. To alleviate this, increase fiber intake from green vegetables, fruits, and drink plenty of water.

Ideal Time to Take Calcium
- Taking Iron and Calcium in the Morning – when is the best time of day to take iron and calcium: Calcium is best absorbed in the morning as the body can utilize sunlight to produce vitamin D, which helps enhance calcium absorption. Drinking calcium in the morning with plenty of water gives optimal results.
- Taking Calcium with Vitamin D: Combining calcium with vitamin D supplements significantly increases the absorption efficiency of this mineral.
- Choosing the Right Time – when is the best time of day to take iron and calcium: If you cannot take it in the morning, you can take calcium after lunch. Avoid taking it in the afternoon or evening as it will limit absorption capacity.
Optimal Supplementation Schedule
Taking Iron and Calcium Together – when is the best time of day to take iron and calcium: Do not take iron and calcium at the same time. Take them at least 2-3 hours apart for effective absorption.

Iron and Calcium Supplementation Schedule – when is the best time of day to take iron and calcium: Here is an example schedule for taking iron and calcium:
- Morning (1 hour after breakfast): Take calcium.
- Noon (1 hour before lunch or 2 hours after lunch): Take iron.
Consulting a Specialist: Before supplementing with iron and calcium, consult a doctor or nutritionist to determine the appropriate dosage and timing based on individual health conditions.
Supplementation Advice
- Iron-rich Foods: Supplement iron from foods such as red meat, liver, beans, dark leafy greens…
- Calcium-rich Foods: Increase calcium from milk, dairy products, sardines, kale, soy products…
- Side Effects: Note possible side effects such as bloating, indigestion, nausea… Stop supplementing and see a doctor if severe symptoms occur.
