The 5 Best Iron Supplements for Kids in 2025

Your kid's energy levels shouldn't depend on luck. Iron deficiency affects millions of children, showing up as fatigue, poor concentration, and frequent illnesses. Many parents miss the signs until their pediatrician orders blood work.

The good news is that choosing the right iron supplement can turn things around quickly. We tested and researched dozens of options to find supplements that actually work without causing stomach upset or being rejected by picky eaters.

This guide covers the 5 best iron supplements for kids in 2025, each solving specific challenges parents face when trying to boost their child's iron levels.

Key Takeaways

• Sugar-free gummy bears and similar formats now deliver complete nutrition without dental damage or blood sugar spikes that traditional supplements cause.

• Foods that have iron aren’t loved by children, which is why they benefit best from supplements combining iron with vitamin C and other nutrients that enhance absorption.

• Look beyond iron content alone because gentler forms like carbonyl iron and ferrous gluconate work better for kids prone to constipation or stomach discomfort.

Overview

For those of you who prefer a bird's-eye view, here are the products. 

1. GOJOY Kids Multivitamin Gummies with Iron

These sugar-free gummies give your kid a complete nutritional boost in one chewable. Each gummy packs essential vitamins and iron to support healthy growth and immunity. They taste like pineapple, which means you won't have to chase your kid around the kitchen every morning.

Sweetened with monk fruit extract instead of sugar, they're gentle on teeth and blood sugar levels. The formula includes vitamin D and other nutrients that picky eaters typically miss.

They're made for toddlers and children aged 3 and up, so you can use them throughout early childhood. No artificial colors or flavors, just straightforward nutrition that actually works.

Main Features:

• Zero sugar formula uses monk fruit extract, protecting teeth while delivering all the nutrients growing bodies need.

• Combines iron with a full spectrum of vitamins in one gummy, eliminating the need for multiple supplements.

• Pineapple flavor appeals to even the pickiest eaters, making daily vitamins something kids actually look forward to.

Why Should You Get It

These gummies solve the picky eater problem without compromising on nutrition. Kids with low iron often struggle with energy and focus, and this formula addresses that while covering other nutritional gaps in one simple step.

2. Nature's Way Kids Smart Iron + Vitamin C

This Australian brand offers iron in two formats: chewable tablets and gummies. Each chewable tablet contains 5mg of iron as ferrous fumarate plus 50mg of vitamin C.

The vitamin C helps your child's body absorb more iron from the supplement and from their regular meals. It tastes like strawberry and is 99.9% sugar-free.

The gummy version delivers 2.5mg of iron per serving, requiring two gummies daily. Both versions work well during growth spurts or when kids are eating less than usual. The chewable tablets are easy to swallow since they break down quickly in the mouth.

The formula supports energy production and healthy immune function without causing constipation, unlike some traditional iron supplements that can upset sensitivstomachs.

Main Features:

• Pairs iron with vitamin C in a single chewable or gummy, maximizing absorption and making the most of each dose.

• 99.9% sugar-free formulation protects dental health while delivering nutrients in a strawberry flavor kids enjoy.

• Available in both chewable tablet and gummy formats, giving parents flexibility based on their child's preferences.

Why Should You Get It

Kids who need flexible dosing options benefit from having both tablet and gummy choices. The combination of iron and vitamin C in one product simplifies supplementation and ensures better nutrient uptake.

3. Floradix Liquid Iron & Vitamin Formula for Children

Floradix makes a dedicated children's formula that comes in liquid form with a raspberry flavor. The product uses ferrous gluconate, an iron supplement form that absorbs well and tends to be gentler on digestion.

Each serving provides iron along with B vitamins and vitamin C from acerola. The liquid format means the nutrients are already dissolved, which can lead to faster absorption compared to pills or gummies.

You measure out doses using a cap marked with measurements, adjusting the amount based on your child's age. Kids aged 3 to 6 need 10ml once daily, while older children need slightly more.

The formula includes herbal extracts from spinach, oat, rosehip, and sea buckthorn. It contains no alcohol, artificial additives, or preservatives. You need to refrigerate it after opening and use it within four weeks.

Main Features:

• Liquid formula delivers pre-dissolved nutrients that absorb quickly through the digestive system without needing to break down tablets.

• Contains B vitamins alongside iron and vitamin C, addressing multiple nutritional needs that affect energy and cognitive function.

• Uses ferrous gluconate instead of harder-to-digest iron forms, reducing the chance of stomach upset or constipation.

Why Should You Get It

Children who struggle with pills or have sensitive stomachs often tolerate liquid iron better. The natural fruit juice base and raspberry flavor make it palatable even to picky kids who resist supplements.

4. Nature Made Iron Gummies with Vitamin C

Nature Made doesn't currently make a dedicated kids iron gummy. Their iron gummies contain 18mg of iron per two gummy serving, which is formulated for adults.

However, the reason we mentioned it is that some parents use these under their pediatrician's guidance by adjusting the dose.

The raspberry-flavored gummies combine ferrous fumarate with vitamin C to enhance absorption. They're USP verified, meaning an independent lab has tested them for quality and purity.

The formula contains no artificial flavors, sweeteners, or synthetic dyes. Nature Made is the number one pharmacist-recommended vitamin brand, which gives parents confidence in their manufacturing standards.

However, the adult iron content and gelatin-based formula make these less ideal than products specifically designed for kids.

Main Features:

• USP verified quality ensures independent lab testing confirms what's on the label matches what's in the bottle.

• Raspberry flavor with vitamin C combines taste appeal with enhanced iron absorption in a convenient gummy format.

• Trusted pharmacist recommended brand provides peace of mind about manufacturing standards and ingredient quality.

Why Should You Get It

Parents who need a reliable adult iron supplement that can be dose adjusted under medical supervision might consider these. The USP verification and brand reputation make them a trustworthy choice when used appropriately.

5. Renzo's Iron Melt-Away Tablets

Renzo's takes a different approach with tablets that dissolve instantly in your kid's mouth. Each tablet contains 9mg of carbonyl iron, a gentler form that causes less stomach upset than traditional iron salts.

The vegan gummies alternative market inspired this sugar-free option sweetened with monk fruit and xylitol. Kids aged 2 to 3 take one tablet daily, while older children need two. The orange flavor comes from natural fruit extracts without artificial colors or additives.

The tablets are about the size of a chickpea but flatter, making them safe and easy to handle. You can let them dissolve naturally or dissolve them in water or juice. The formula is free from the eight common allergens and is non-GMO.

The company makes their products in a family-owned facility in Florida with NSF certification and third-party lab testing.

Main Features:

• Carbonyl iron form absorbs steadily and minimizes digestive discomfort compared to traditional iron salts used in most supplements.

• Melty tablet technology dissolves on contact with saliva, eliminating the need to chew or swallow pills.

• Free from all eight common allergens plus sugar, gluten, and artificial ingredients, making them suitable for kids with dietary restrictions.

Why Should You Get It

Kids who struggle with pills or have texture sensitivities often prefer the melt away format. The gentle iron form and allergen free formula work well when stomach issues or allergies complicate supplement choices.

Final Words

Getting enough iron matters more than most parents realize. Kids need it to grow properly, stay energized, and develop healthy cognitive function. The five supplements we covered each solve different problems.

GOJOY Kids Multivitamin Gummies with Iron remains the top choice because it combines comprehensive nutrition with zero sugar and a formula kids actually enjoy. You're not just addressing iron needs but filling multiple nutritional gaps in one daily gummy.
