Iron Supplements How Soon Will I Feel Better

It’s common knowledge that iron is essential for our bodies. It helps transport oxygen in the blood, supports a healthy immune system, and is necessary for cell growth. 

Because of this, many people take iron supplements to ensure they are getting enough of this important nutrient. 

However, taking too much iron can actually have negative consequences.

Do you feel worse after taking an iron supplement?

If so, you’re not alone. Many people experience unpleasant side effects when they start taking iron supplements. This can be confusing and frustrating, especially if you’re trying to improve your health. 

In this blog post, we will discuss the most common side effects of iron supplementation and what you can do to reduce or eliminate them.

What is Iron Overload?

Many people are unaware of the dangers of iron overload.Iron overload occurs when there is too much iron in the body.

This can happen for a variety of reasons, including genetic disorders, multiple blood transfusions, or taking iron supplements when you don’t need them. 

While a small amount of iron is essential for good health, too much iron can be dangerous. Excess iron can build up in organs, causing damage and even death.

What Causes Iron Overload?

There are a few different ways that someone can develop iron overload. One way is through a genetic disorder called hemochromatosis. Hemochromatosis is an inherited condition that causes the body to absorb too much iron from the diet.

People with hemochromatosis require treatment to remove excess iron from their bodies as their iron absorption is not working properly.

Another way that someone can develop iron overload is by having multiple blood transfusions. Blood transfusions are often given to people with conditions like sickle cell disease or thalassemia. 

These transfusions help to treat these conditions, but they can also lead to iron overload if a person has them on a regular basis. However, this is much more rare.

Finally, taking iron supplements when you don’t need them can also lead to iron overload. People who take iron supplements without being diagnosed with an iron deficiency are at risk for developing this condition.

Symptoms of Iron Overload

The symptoms of iron overload can vary depending on the severity of the condition. In some cases, there may be no symptoms at all. 

However, if the condition is more severe, you may experience fatigue, weakness, weight loss, abdominal pain, and diabetes.

If you experience any of these symptoms after taking iron supplements, it’s important to see a doctor right away so they can determine if you have iron overload and develop a treatment plan accordingly.

If you suspect iron overload, you may want to order an online blood test for iron and anemia specifically (which will also tell you if your iron levels are too high).

Treatment for Iron Overload

If you’re diagnosed with iron overload, there are a few different treatment options available.

One option is phlebotomy, which is a medical procedure where blood is removed from the body in order to reduce the amount of iron in the blood.

Another option is chelation therapy, which is a medical procedure where medication is used to remove excess iron from the body.

Finally, making lifestyle changes such as changing your diet or taking iron supplements as directed by your doctor can also help to treat this condition. 

How Much Iron Do I Need Per Day?

recommended daily allowances for iron

According to the National Institutes of Health, most adults need between 8 and 18 milligrams (mg) of iron a day. Pregnant women need more—27 mg a day.

Children need different amounts depending on their age. For example, infants up to 6 months old need 0.27 mg a day, while children 9–13 years old need 8 mg a day.

The body needs iron to make hemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body. If you don’t have enough iron, your body can’t make enough hemoglobin, and you may develop iron deficiency anemia.

This is a common type of anemia that occurs when your blood doesn’t have enough healthy red blood cells. Iron deficiency anemia can make you feel tired and weak. 

Foods that Contain Iron


You can get the iron you need from food or from supplements. Foods that are high in iron include meats (especially liver), eggs, leafy green vegetables, beans, and fortified cereals.

Non-meat sources of iron are not as easily absorbed by the body as meat sources, so it is important to eat foods that are high in vitamin C along with non-meat sources of iron.

The body absorbs more iron from supplements if they are taken with vitamin C-rich foods or juices. Here is a list of iron rich foods from the Red Cross.

How to Tell If I Have Too Much Iron?

Having too much iron in your body can be harmful. One way to know if you have too much iron is to keep track of the amount you’re consuming each day through a mindful food journal.

Make sure to include not only the meals you’re eating, but also any snacks or drinks that contain iron. Supplements can also contain high levels of iron, so be sure to read the label and compare it to the amount you should have each day.

If you think you might have too much iron in your body, there are some things you can look out for. 

Excess iron can lead to headaches, joint pain, fatigue, gastrointestinal issues like constipation or diarrhea, and even heart problems. If you experience any of these symptoms, talk to your doctor to see if you might need to cut back on your iron intake.

Why do I feel weird after taking iron supplements?

As you know by now, iron deficiency can lead to a wide range of problems, including fatigue, anemia, and weakness. Iron supplements are often recommended for people who are deficient in this mineral, but they can also cause side effects such as nausea and constipation.

In some cases, people may also experience feelings of anxiety or irritability after taking iron supplements.

While these side effects are typically mild and disappear within a few days, they can be bothersome for some people. If you experience any negative side effects after taking iron supplements, be sure to talk to your doctor.

How long does it take for your body to adjust to iron supplements?

When taken as directed, iron supplements can be effective in treating anemia and restoring normal oxygen levels in the blood.

However, it is important to be aware that it can take several weeks or even months for the body to adjust to iron supplements and reach full saturation.

During this time, side effects such as nausea, constipation, and diarrhea are common. In most cases, these side effects will subside as the body adjusts to the supplement.

However, if they persist or become severe, it is important to speak to a doctor. With time and patience, iron supplements can be an effective treatment for iron deficiency anemia.

Types of Iron Supplements

There are a few different types of oral iron supplements available on the market. The most common is ferrous sulfate, which comes in tablet form. Ferrous sulfate is generally well-tolerated, but it can cause stomach upset in some people.

Another option is an iron pill, which is a smaller, easier-to-swallow tablet that contains a lower dose of iron. Iron pills are less likely to cause gastrointestinal side effects but may need to be taken more frequently to achieve the same result.


It’s important to make sure you are getting enough iron in your diet; however, it’s also possible to have too much iron in your system. Iron overload can occur for a variety of reasons and can lead to serious health problems if not treated properly.

If you experience any symptoms after taking iron supplements, be sure to see a doctor right away so they can determine if you have iron overload and develop a treatment plan accordingly.
