For many parents, kids' multivitamins are a safety net — a way to fill nutritional gaps when even healthy meals fall short.

But with so many options that look (and taste) like candy, it's hard to know which actually deliver the nutrients growing bodies need.

We partnered with Pediatric Dietitian Sarah Keller (MS, RD) to break down when children truly benefit from a multivitamin and what matters most when choosing one. After all, more than 90% of kids don't eat enough fruits and vegetables — two of the main sources of essential vitamins and minerals.¹

Combining Keller's expertise with hands-on reviews from parents on our team, we compared the leading kids' multivitamins on nutrition, other ingredients, form factor, allergens, taste, and price. One brand stood out as the clear winner — keep reading to find out which.

Should My Child Be Taking a Multivitamin?

According to dietitian Keller: probably. She explains why many families can benefit from kids' multivitamins:

What to Look For in a Kids' Multivitamin

Let's start with the basics: what should parents look for when choosing a children's multivitamin?

According to Pediatric Dietitian Sarah Keller (MS, RD), it comes down to a balance of nutrients and form that encourages consistency without unnecessary additives.

So how do today's leading brands compare when it comes to nutrients, safety, and taste? Let's find out.

The Top Kids' Multivitamins, Compared

We've highlighted in green the top products in each category.

Vitamin & Mineral Content

🥇 Wonderkid Kids Daily Multivitamin: contains 18+ essential vitamins and minerals, including the three nutrients children are most commonly deficient in: DHA (150 mg from algae oil) for brain development, chelated iron (8 mg) for focus and energy, and zinc (2 mg) for immune function. Plus 2 billion probiotic cultures and methylated B-vitamins — all in 2 gummies per day, with 0g sugar.

🥈 Hiya: A solid 15+ nutrients including calcium — the only product in our test with calcium. However: No DHA, no iron. The very nutrients experts say matter most are completely missing.

❌ First Day, Nature Made, L'il Critters: Only 9–11 nutrients. No DHA, no iron, no zinc. Essentially just basic vitamins C and D — not enough for the price.

Other Ingredients & Sugar

🥇 Wonderkid, Hiya, Mary Ruth's: All three come with 0g added sugar and no artificial colors, flavors, or preservatives. Wonderkid and Mary Ruth's gummies are vegan (gelatin-free).

❌ L'il Critters: The first two ingredients on the label? Glucose syrup and sugar. Plus artificial colors. It's basically vitamins wrapped in candy.

❌ Llama Naturals: Markets itself as "plant-based" but contains 4g sugar per serving — the highest in the entire test.

SmartyPants and Olly come in at 3g sugar and use gelatin — not suitable for vegetarian/vegan families.

Form Factor

🥇 Wonderkid: Soft gummies, safe for ages 2+. No added sugar, no choking risk like harder gummies. Kids ask for them by name every morning.

🥈 Hiya: Chewable tablets, also safe from age 2 — a safe, low-sugar option. However, not every child accepts tablets, especially toddlers.

All others: Standard gummies, recommended only ages 4+ per expert guidance due to choking risk. Many contain gelatin and added sugar.

Allergens & Safety

🥇 Wonderkid, Hiya, Mary Ruth's, Llama Naturals, First Day: All free from common allergens (gluten, dairy, soy, nuts, fish). The safest choice for sensitive kids.

❌ L'il Critters: Processes peanuts, milk, and fish in the same facility. A clear no-go for allergy-prone children.

❌ SmartyPants: Contains fish oil — not suitable for kids with fish allergies or vegetarian families.

Taste (Kids' Taste Test)

🥇 Wonderkid & L'il Critters: The clear taste favorites among kids. Wonderkid uses natural berry flavor — no artificial flavoring. L'il Critters tastes great too, but it's essentially candy with sugar and artificial flavors.

🥈 Hiya and Mary Ruth's: Good taste. Some kids find Hiya tablets take some getting used to.

❌ First Day: Arrived melted in our test and was disappointing flavor-wise. At over $1.40/day, that's unacceptable.

Value for Money

🥇 L'il Critters ($0.14/day) and Nature Made ($0.22/day) are the cheapest — but also the most nutrient-poor. You get what you pay for.

🥈 Hiya ($0.42/day): Excellent value for a premium product — but without DHA and iron.

Wonderkid ($0.95/day with 3-pack): Not cheap — but the only product that combines DHA, iron, zinc AND probiotics. The ingredients (algae DHA, chelated iron) are expensive to manufacture. Compare the cost of buying separate DHA and iron supplements — Wonderkid actually saves you money.

❌ First Day ($1.43/day): The most expensive product in our test — with only 9 nutrients. Poor value.

Our Verdict: The Clear Winner

Most kids' vitamins aren't bad — they're just incomplete. They deliver vitamin C and D, but leave out the nutrients children need most: DHA for the brain, iron for cognitive development, zinc for immunity.

Wonderkid is the only product in our test that combines all three in one formula — sugar-free, additive-free, with a 90-day money-back guarantee.
