What Are the Benefits of Iron for Developing Children?

Expert

Iron plays a role in our body's ability to fight infection, and deficiency can lead to cognitive impairments.

Iron is a crucial mineral for a child's development. When included in a balanced diet and paired with adequate sleep and exercise, it will contribute to a child's growth and physical development. As Katie Drakeford points out, it also has other benefits, such as mental development and fostering a robust immune system.

How to Choose Iron Supplements for Kids

In this guide, we’ll tell you what to look for when selecting an iron supplement that both meets your child’s nutritional needs and will be something they’ll be willing to take.

Choose a Supplement That Fits Your Child’s Age to Ensure a Proper Dose

Expert

Iron needs vary based on age and sex, so choosing an age-appropriate dose is vital.

Many supplements provide multiple dosage sizes depending on the number of drops or gummies administered, which can be helpful for parents looking for a single supplement that can be given to multiple children with proper dosing.

On the other hand, choosing a dosage for a different age group than your child runs the risk of the amount of iron they ingest being too low or too high. These nutritional needs depend significantly on the child's stage of development.

Look for Ferrous Iron for Better Absorption

Expert

Ferrous iron may be the preferred iron supplement because of its higher bioavailability.

When looking for any supplement, choosing a form the body can metabolize and use efficiently is essential. The fewer steps needed to metabolize a supplement within the body, the better. In the case of iron supplements, ferrous compounds are typically preferable. Katie Drakeford adds that Ferrous Sulfate and Ferrous Gluconate are two popular forms.

Ferrous Sulfate "has a higher bioavailability compared to other forms of iron supplements; thus your body can absorb more of the nutrients" and "Ferrous Gluconate may cause fewer gastrointestinal side effects than ferrous sulfate and ferrous fumarate because it contains less elemental iron.

Consider How Your Child Will Take the Supplement

Expert

Gummy candies have added flavors and sugars that make them more appealing to children.

Kids can be picky regarding their vitamins, and particularly young children shouldn't swallow pills or capsules. As such, most iron supplements for children come as liquids, chewables, or gummies. Katie Drakeford recommends liquid supplements for infants and particularly young children, as they can be mixed into the food and drinks that your child already enjoys and are thus the easiest to ingest.

After age two, many children are ready to move to gummies and chewables. Drakeford adds, "Most children learn to start taking pills between the ages of 5 and 10, but the exact time your child may be ready is very individualized." She also suggested this resource for parents who believe their children are ready to try pills and capsules.

Consider Iron Supplements With Added Vitamins to Maximize the Effects

Expert

Adding a source of Vitamin C (like citrus fruits, tomatoes, strawberries, etc) can help enhance iron absorption.

As with taking the proper form of iron, specific vitamins and minerals can also help the body utilize iron more efficiently. Our expert consultant has highlighted the following vitamins and minerals for your consideration:

Vitamin C to enhance iron absorption
Folic acid and B12 to "improve anemia in adolescent girls."
Drakeford adds, "Studies show that Vitamin A supplementation may improve hemoglobin and ferritin levels for people with low Vitamin A status."
Copper helps the body use iron.

Remember, consult your healthcare provider before adding supplements to your child's diet.

Look for Third Party Testing and Certifications as a Sign of Quality

Expert

Checking for a trusted brand with third-party testing gives insight into the safety, purity, and efficacy of the product.

Since there is such a wide variety of supplements on the market, it can be challenging to discern the quality of each one. After all, through the bottle, all those gummies look the same. Katie Drakeford recommends overcoming the hurdle by looking for brands and testing from reputable third-party organizations.
