Iron is a mineral essential for various bodily functions, the most crucial of which is the transportation of oxygen throughout the body. It is a key component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to our tissues and organs.

When iron levels drop, the body struggles to produce sufficient healthy red blood cells, potentially resulting in iron deficiency anemia. To tackle this deficiency, many individuals turn to iron supplements to replenish their iron levels.

However, the timing of iron intake has sparked interest regarding whether taking iron before bed disrupts sleep. 

This article will explore iron supplements and sleep. It will answer the question, “Does taking iron at night keep you awake?” and examine the potential effects and considerations for iron supplementation.

How Iron Affects the Body

Iron plays a vital role in the production of red blood cells and the transport of oxygen. A key component of hemoglobin, which is a protein found in red blood cells, relies on iron.

Hemoglobin’s structure enables it to bind with oxygen in the lungs and transport it to tissues and organs throughout the body. Without adequate iron, our body faces numerous problems. It cannot produce enough hemoglobin, leading to decreased red blood cells and, consequently, diminished oxygen delivery.

This ultimately leads to iron deficiency anemia, which is characterized by fatigue, weakness, and several related symptoms.

Muscle function

Iron is also a component of myoglobin, a protein that helps store and transport oxygen in muscle tissue. This function is vital for muscle function and energy production. 

According to the National Institutes of Health (NIH), “Iron is an essential mineral, meaning that he body cannot produce it.” They also explain how iron deficiency can result in anemia.

Does taking iron at night keep you awake?

The relationship between iron supplementation and sleep is complex and not fully understood. While iron is a crucial building block of health, some individuals question, does taking iron at night keep you awake, because they report sleep disturbances during supplementation.

Here’s a breakdown of what we know

Gastrointestinal discomfort

Iron taken on an empty stomach can cause side effects such as nausea, constipation, or stomach cramps. These discomforts can disrupt sleep.

The Circadian Rhythm

Emerging research investigates the relationship between iron absorption at night and the circadian rhythm. 

Since iron is involved in various bodily processes, some studies indicate a link between iron intake and the sleep-wake cycle. However, further research is necessary to fully understand this connection.

Individual variability

People react differently to iron supplements. Depending on your sensitivity, some may experience no sleep disturbances, while others may.

Anemia and sleep quality

Iron deficiency anemia alone may cause sleep disturbances. So, those who are anemic may see improved sleep when taking iron supplements.

To further explore the relationship between sleep and anemia, the Sleep Foundation offers more in-depth insights into the correlation.

Best time to take iron supplements for optimal absorption

Here is a breakdown of the best practices for optimal iron supplementation:

Empty stomach

Iron is best absorbed on an empty stomach, ideally one hour before or two hours after meals.

Considerations

Taking iron on an empty stomach can lead to gastrointestinal side effects like nausea or discomfort. If this happens, take it with a small amount of food to alleviate the symptoms.

Enhancing absorption

Vitamin C: Taking iron with vitamin C as a supplement or glass of orange juice can enhance absorption.

Substances to avoid

  • Calcium: This can inhibit absorption, so avoid taking iron with calcium-rich foods or supplements such as yogurt, milk, or antacids.

  • Caffeine and Tannins: Coffee, tea, and other caffeinated beverages, as well as foods containing tannins, can interfere with absorption, so try to avoid them around the time of supplementation.

  • High-fiber foods: These should also be avoided around the time you take iron.

Side effects of taking iron at night

The common side effects of taking iron can be constipation, nausea, stomach cramps or pain, and diarrhea. But can iron cause insomnia? Yes, if you are experiencing these symptoms, the side effects can disrupt your sleep.

If you experience side effects from iron supplementation, many healthcare professionals recommend taking iron supplements with food, as it might be necessary. 

This approach reduces absorption somewhat but will help minimize the adverse side effects associated with gastrointestinal issues.
