Best Supplements for Iron Deficiency

Iron is an essential mineral for the human body, mainly for blood health. It supports hemoglobin and myoglobin production to oxygenate the blood and muscles, helps create enzymes that metabolize energy, and supports the immune system supporting white blood cell production. 

An iron deficiency can cause a range of health conditions, including anemia and fatigue. It’s a common issue for women of reproductive ages and athletes. Supplements can address low levels of iron in the body, but overuse can cause other adverse side effects. People typically take these supplements orally and as tablets, capsules, or liquids.

What Is an Iron Supplement?

An iron supplement is a pill, capsule, tablet, or liquid taken to provide people with extra iron. While it’s possible to ingest enough iron through food, some people require additional support to maintain healthy levels. 

It is beneficial to take iron supplements because they will help red blood cell formation, improving your immune system. People will also often notice they have extra energy. 

Taking iron supplements as suggested is typically safe, though some people experience minor digestive upset in the beginning.

There are risks associated with taking too many iron supplements. Overusing iron supplements can lead to toxic levels in the body, which can trigger vomiting, diarrhea, and extreme stomach pain. If left untreated, iron toxicity can damage the liver and brain. 

What Do Iron Supplements Do?

Iron supplements provide the human body with the iron it needs to function. Without iron, the body is unable to develop and produce hemoglobin for red blood cells. Hemoglobin is responsible for carrying oxygen throughout the body to the lungs and muscles.

Iron is necessary for hormone production. As a result, people with low iron may have fertility issues. So, iron supplements are often prescribed to people struggling to get pregnant.

How Many Iron Supplements Does Our Body Need?

The amount of iron a person needs in their daily diet depends on their age, sex, and diet. Women usually need more iron because they use more during menstruation. 

Diet is also a significant factor for many people who can’t get enough iron. It can occur because they don’t eat enough iron-rich foods or have an underlying medical condition that causes low iron. 

Notably, there is a myth that vegetarians and people who stick with plant-based diets struggle to get the iron they need. There’s a tendency to push these supplements on vegans and vegetarians to meet their daily iron requirements, but it’s not always necessary. It’s best to seek a physician’s opinion and have blood work done before starting an iron supplement.

How Much Will It Cost for Iron Supplements?

Iron supplements cost anywhere from $9 up to $25 for a month’s supply. It’s a generally inexpensive supplement with most suppliers providing them at $15 or less per month. Many companies and retailers offer additional discounts for those who sign up for subscriptions through their websites.

What Health Supplements Can You Take With Iron?
