Top 8 Best Iron Supplements for Runners

UpdatedMay 29, 2024

Iron is an essential mineral that is involved in several vital functions within the body. It plays a critical role in the production of hemoglobin, which is responsible for carrying oxygen to the body's tissues. Runners, in particular, require sufficient iron levels to maintain their performance and avoid the risk of anemia. However, many athletes struggle to meet their daily iron requirements through diet alone, making iron supplements a popular choice.

When it comes to choosing the best iron supplement for runners, there are several factors to consider. The most important of these is the type of iron used in the supplement. Iron supplements come in two main forms: heme and non-heme iron. Heme iron is derived from animal sources and is more readily absorbed by the body. Non-heme iron, on the other hand, is derived from plant sources and is less efficiently absorbed.

Other factors to consider when choosing an iron supplement for runners include the dosage, form (tablet, capsule, liquid), and any additional ingredients that may affect absorption or digestion. It's also important to note that excessive iron intake can be harmful, so it's essential to choose a supplement that provides the right amount of iron without exceeding the recommended daily intake.

We spent hours researching and testing various iron supplements to identify the best options for runners. In the next section, we'll share our top picks and explain why they stand out from the rest.

Buying Guide

When it comes to choosing the best iron supplement for runners, there are a few key factors to consider. We recommend looking at the following features before making a purchase:

Form of Iron

Iron supplements come in various forms, including tablets, capsules, liquids, and powders. Each form has its own advantages and disadvantages, so it's important to choose one that suits your needs and preferences.

Tablets and capsules are the most common forms of iron supplements and are easy to take on the go. Liquids and powders may be more convenient for those who have difficulty swallowing pills or prefer to mix their supplements into drinks or smoothies.

Dosage

The recommended daily dose of iron for runners varies depending on age, sex, and other factors. It's important to choose a supplement that provides the appropriate amount of iron for your needs.

Some supplements provide a high dose of iron in a single serving, while others provide a lower dose that can be taken multiple times throughout the day. We recommend consulting with a healthcare professional to determine the appropriate dosage for your individual needs.

Absorption

Iron supplements are not always easily absorbed by the body, which can lead to digestive issues and other side effects. Look for supplements that contain iron in a form that is easily absorbed, such as ferrous bisglycinate or iron glycinate.

Some supplements also contain other nutrients, such as vitamin C or folate, which can help improve iron absorption and provide additional health benefits.

Price

Iron supplements can vary widely in price, depending on the brand, dosage, and other factors. While it's important to choose a high-quality supplement, it's also important to consider your budget.

We recommend comparing prices and reading reviews from other runners to find a supplement that provides the best value for your money.
