Worried that your diet is lacking in iron? Want to increase your iron intake? If so, you’ve come to the right place. In this guide we’ll discuss everything you need to know about iron, including what it is, why it’s important, and proven ways to increase your iron levels.

What is iron?

Iron is a mineral that has several roles throughout the body. Its main function is to carry oxygen in the hemoglobin of red blood cells. This enables the cells to produce energy. Iron also helps to remove carbon dioxide from the cells. It’s even needed to make certain hormones.

When the body doesn’t have enough iron, red blood cells aren’t able to carry oxygen efficiently. This condition is called iron deficiency anemia.

Iron found in food comes in two different forms: heme and nonheme. Plant foods, like vegetables, and iron-fortified food products, like cereal, contain nonheme iron. Poultry, meat, and seafood contain both heme and nonheme iron.

The body most efficiently absorbs iron from plant sources when eaten with poultry, meat, or seafood, as well as when eaten with foods that contain high amounts of vitamin C, including citrus fruits, strawberries, tomatoes, and broccoli.

How much iron do I need in a day?

There are many factors that dictate how much iron you need on a daily basis, including your age, sex, and your diet. Vegetarians, vegans, and others who don’t consume poultry, meat, or seafood, need about twice as much iron as the average person. This is because the body doesn’t absorb non-heme iron, which comes from plant foods, as well as heme iron, which is found in animal products.

Adult men aged 19-50 years old need around 8 mg of iron each day, while women of the same age need about 18 mg. Adults 51 years and older need 8 mg of iron each day to maintain healthy levels. It’s important to note that pregnant women need more iron and should consume around 27 mg a day.

What are the symptoms of low iron?

An iron deficiency rarely causes obvious symptoms. This is because the body stores iron in the muscles, bone marrow, and various organs, including the liver and spleen. When iron stores become low, iron deficiency anemia sets in.

When this happens, the red blood cells contain less hemoglobin because of their reduced size. This means that there’s less oxygen in the blood that’s carried from the lungs throughout the body.

Some of the most common symptoms associated with iron deficiency anemia include:

  • Weakness and tiredness

  • Lack of energy

  • Digestive problems

  • Inability to concentrate

  • Memory issues

If you experience any of these symptoms, it’s best to contact your doctor, who can perform testing to determine if you’re suffering from iron deficiency anemia.

Who is at risk of not getting enough iron?

Most people get plenty of iron from their diet alone. However, there are certain groups of people who are at a higher risk of being deficient in iron. These include:

  • Pregnant women

  • Teens and women with heavy periods

  • Frequent blood donors

  • Infants, especially premature or low-birth weight

  • People with certain health conditions (heart failure, cancer and GI disorders)

Vegetarians and vegans are also at an increased risk of an iron deficiency.

Are there different types of iron supplements?

There’s no shortage of health supplements available today, including iron supplements. Iron is found in most multivitamin supplements and there are also iron only supplements. Iron supplements can contain four types of iron: ferrous sulfate, ferrous gluconate, ferric citrate, or ferric sulfate.

NOTE: Taking too much iron can be toxic. Always talk with your doctor first before adding iron supplements to your daily regimen. Also, iron supplements can be deadly to young children, especially those under the age of 6. Be sure to safely store these products so that they are out of reach for children.

How to choose an iron supplement

There are plenty of iron supplements to choose from. Here are all of the factors you need to consider when choosing an iron supplement to add to your wellness regimen.

1. Don’t take an iron supplement just because

Iron isn’t a nutrient that you want to take just for the heck of it. The fact is that most people get the iron they need from the foods they eat. However, if you experience frequent headaches and fatigue, you may have an iron deficiency.

To determine your iron levels, schedule an appointment with your doctor. In some cases, a severe iron deficiency cannot be treated with a supplement alone. You may need to take additional supplements, such as vitamin A, to help your body better absorb iron.

2. Figure out your preferred form

Iron supplements are available in capsule, tablet, liquid, and even gummy form. There are also slow-release iron supplements that deliver iron over a longer period of time. The type of iron you take is totally dependent on your preferences. Some people like the convenience of a gummy while others prefer liquid supplements.

If you’re taking an iron supplement because of a doctor recommendation, they may recommend a specific type of supplement. Either way, you’re sure to find an iron supplement that’s quick, easy, and convenient to take.

3. Determine your dosage

Too much iron can cause all sorts of side effects and potential health issues. If you’re unsure of what your ideal dose is, the next step is to undergo blood testing. You should always take iron supplements as instructed. As discussed earlier, the average adult male needs 8 mg of iron while adult females need 18 mg a day. Pregnant women should take 27 mg of iron daily.

4. Check type of iron

Iron supplements can contain four different types of iron and they each have varying levels of elemental iron. While all four forms of iron are well-absorbed, some offer more elemental iron than others.

Out of the four, ferrous fumarate contains the largest amount of elemental iron, which may be too strong for some people. Typically, ferrous sulfate is the recommended type of iron. It offers a decent amount of elemental iron while also being quite affordable.

5. Choose between heme and nonheme iron

To recap: There are two types of iron: heme and nonheme. Heme iron is found in animal products, including poultry, meat, and seafood. Heme iron is most easily and efficiently absorbed by the body.

On the other hand, nonheme iron is found in plant products, but also found in meat. However, the absorption of nonheme iron can be negatively impacted by phytates and caffeine. If you’re taking a nonheme iron supplement, be sure that it’s formulated with vitamin C or take a vitamin C supplement.

6. Be aware of the side effects

Taking an iron supplement can cause a variety of side effects, including upset stomach, constipation, and dark stools. You may even have a strange taste in your mouth. If you experience severe and unpleasant side effects, you may need to switch to a different supplement.

Other ways to increase iron intake

Supplements are only one way to increase your iron intake. Iron is naturally found in a wide variety of foods. It’s also added to many fortified food products, such as cereals. Most people can get their recommended amounts of iron by eating a wholesome diet that includes foods like:

  • Iron-fortified cereals and breads

  • White beans, kidney beans, and lentils

  • Spinach

  • Peas 

  • Poultry, lean meat, and seafood

  • Nuts (ie. cashews)

  • Dried fruits, especially raisins

  • Dark chocolate

Eating two or three servings of the foods listed above will provide your body with the iron it needs. This is why it’s important to eat a varied diet of whole foods. A balanced wholesome diet typically provides all of the nutrients your body needs, including iron.

Can too much iron be harmful?

Yes, as with any nutrient, too much of a good thing can turn bad. Taking a high dose iron supplement can cause digestive issues like upset stomach, nausea, constipation, diarrhea, vomiting, and abdominal pain. Continuous large amounts of iron can also cause more serious effects, including ulcers and inflammation of the stomach lining.

High doses of iron may also interfere with zinc absorption. Extremely high doses of iron can be fatal, but this requires hundreds of thousands of mg. 

Does iron interact with other supplements and medications?

Yes, iron supplements can interact and/or interfere with other supplements and medications. This is why it’s important to consult with your doctor before adding an iron supplement to your daily health regimen.

Here are some interactions to be aware of:

  • Calcium supplements

  • Medications used to treat thyroid cancer, hypothyroidism, and goiter (active ingredient: levothyroxine)

  • Medications used to treat Parkinson’s disease and restless leg syndrome (active ingredient: levodopa)

  • Proton pump inhibitors (active ingredients lansoprazole and omeprazole)

If you take any of these medications or supplements, be sure to discuss adding an iron supplement to your routine with your doctor first.

Final thoughts

An untreated iron deficiency can have short- and long-term impacts on your health. If you suspect that you have iron deficiency anemia, it’s important to undergo blood testing, which is the only way to check your iron levels.

If you’re deficient in iron, taking a high quality iron supplement can have a huge impact. Eating the right foods can also help to increase your iron levels. With these tips and best products, you can boost your iron levels in a healthy range.
