Kids' vitamins and label accuracy: what the new Consumer Reports results mean

On November 10, 2026, Consumer Reports (CR) published lab results for 21 children's vitamins sold in the US, from brands including Flintstones, Hiya, Nature Made and SmartyPants. Every one of the 21 products had at least one nutrient outside the range CR used for label accuracy. Of 206 nutrient results across all products, 88, or 43%, fell outside that range, with some nutrients at more than five times the labeled amount. CR also found trace heavy metals in all of the products, none above the level its scientists treat as a concern, and it said every product was safe to take.

Short answer: this is a quality-control story more than a safety scare. Most healthy children do not need a daily multivitamin at all, according to the American Academy of Pediatrics. If a child does need one, a third-party certification mark, a dose close to the Daily Value for the child's age, and keeping gummies locked away matter more than the brand name or the flavor.

What Consumer Reports measured

CR bought one to three lots of each product and sent them to an accredited outside laboratory. Each was analyzed for 12 nutrients (vitamins A, C, D, E, B1, B2, B3, B5, B6 and B9, plus iodine and zinc) and for arsenic, cadmium, lead and mercury. CR compared the average amount found with the label and with the US Pharmacopeia (USP) tolerance range for each nutrient and product format. USP's minimum is typically 90% of the labeled amount; the upper end varies by nutrient and format. CR then checked whether any amount went above the tolerable upper intake level (UL) for the age group the product is sold for.

• Which nutrients drifted most. 85% of products containing vitamin B1 (thiamine) were out of range, as were 60% of those with vitamin A, 50% of those with iodine and 48% of those with folate.
• Gummies versus chewables. Gummies were more likely to land within or above the range. All nine chewables, tablets, capsules and powders had at least one nutrient below the threshold. In three of them, Flintstones Complete Chewable, Renzo's Picky Eater Kids Multi with Iron and Walmart's Equate Kids Chewable Complete Multivitamin, 11 of the 12 nutrients were outside the USP range.
• Large overages. USP allows vitamin C in gummies up to 250% of the label. CR found vitamin C from 50% of the label to 531%. The 50% figure is a chewable, and the 531% figure is a gummy. Vitamin B5 in gummies, which has no USP range, ran from 64% to 564% of the label.
• Above the upper limit. Two of the 21 products, from Equate (Walmart) and NaturesPlus, had at least one nutrient above the UL for some of the ages they are sold for. The nutrients involved were niacin, folic acid and zinc.
• Certified products did better as a group. Three products each had one nutrient out of range: Nature Made Kids First Multi + Omega-3 Gummies, Olly Kids Multi + Probiotic, and SmartyPants Kids Organic Multi & Omegas. All three carry third-party certification.

Several companies disputed the findings. Bayer, which makes Flintstones, said the batch CR bought met industry, regulatory and safety requirements at release and called CR's result an outlier. Amazon said the results for its Mama Bear product did not reflect the product's composition. Nestlé Health Science, Renzo's and SmartyPants pointed to differences in laboratory methods. Piping Rock said its own results for the same Li'l Critters lots met specification at release. CR said it stands by its methods. CR also notes that its results are a snapshot of the lots it bought, that it is not a regulator and that no legal conclusion can be drawn from its findings.

What the US rules require

FDA does not approve dietary supplements before they are sold, and a company generally does not have to show FDA its safety evidence. FDA does set rules for what the Supplement Facts panel must mean. For a vitamin or mineral that has been added to a product, the amount in a composite sample must be formulated to be at least equal to the amount declared on the label. The same rule allows reasonable excesses over the labeled amount within current good manufacturing practice, which is why many makers add extra to cover losses over shelf life. Several companies gave CR that reason for high results. USP's tolerance ranges are a voluntary industry standard unless a product carries USP certification.

One rule is not optional. Any dietary supplement in solid oral form, such as a tablet or capsule, that contains iron or an iron salt as an iron source must carry this warning: "WARNING: Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately." The National Institutes of Health says about 4,600 children go to an emergency room each year because of dietary supplements, most after taking a vitamin or mineral unsupervised. NIH also says child-resistant packaging is not required for supplements. That is not the rule for every iron product: a dietary supplement with 250 mg or more of elemental iron in one package must use child-resistant packaging, above set concentrations, with narrow exceptions for iron used only as a color and for some powders.

Upper limits for young children

The three nutrients CR found above the UL have low limits for small children, and two of the limits apply only to the forms added to supplements and fortified foods. The ULs, set by the National Academies and published by the NIH Office of Dietary Supplements, are:

• Zinc: 7 mg a day at ages 1 to 3, 12 mg at 4 to 8 and 23 mg at 9 to 13, from all sources.
• Folic acid: 300 mcg a day at ages 1 to 3, 400 mcg at 4 to 8 and 600 mcg at 9 to 13, counting only folic acid from supplements and fortified foods.
• Niacin: 10 mg a day at ages 1 to 3, 15 mg at 4 to 8 and 20 mg at 9 to 13, counting only supplemental niacin from supplements and fortified foods, not niacin naturally present in food. The limit does not apply when niacin is given under medical supervision.

Many children already get folic acid and niacin from fortified cereal, bread and crackers, so a multivitamin is added on top of that, not instead of it. A product dosed for adults, or two gummies where the label says one, can push a small child past these limits.

Does a child need a multivitamin?

Usually not. The American Academy of Pediatrics says healthy children eating a normal, well-balanced diet do not need vitamin supplements beyond the recommended dietary allowances, and that there is no evidence supplements boost immunity or prevent serious illness. The exceptions it lists are children on very limited or restrictive diets, children diagnosed with a deficiency and children with a medical condition that raises the risk of one. Its vitamin D advice is 400 IU (10 mcg) a day for infants under 1 year and 600 IU (15 mcg) a day for children over 1, and a pediatrician may recommend a supplement to reach that. CDC data from 2017 to 2018 show that 34.0% of US children and teens had used a dietary supplement in the past 30 days, and 23.8% had used a multivitamin-mineral product.

Our view

• Start with whether a supplement is needed at all. Ask your pediatrician, and bring a few days of what your child actually eats. A food diary tends to show that cereal, milk and bread already cover a lot.
• If you do buy one, look for a USP Verified or NSF certification mark. In CR's results, three certified products each had one nutrient out of range and were among the closest to their labels. Certification did not keep every product that close: Garden of Life Kids Multivitamin Powder, which is certified, had five nutrients outside the range. Claims such as "picky-eater approved" or "clean" are marketing terms, not certifications.
• Pick a dose close to 100% of the Daily Value for your child's age, not a product with several hundred percent. Check zinc, folic acid and niacin against the limits above, and remember fortified foods.
• Treat gummies like medicine. Store them out of reach, do not call them candy, and keep any iron-containing product locked away. If a child swallows a handful, call Poison Control at 1-800-222-1222.
• One lab report on the lots CR bought is not a verdict on a brand. The companies' own results and CR's results disagree in several cases. The pattern across 21 products is more useful than any single score.

FAQ

Were any of the kids' vitamins unsafe?

CR said every product it analyzed was safe to take. Heavy metals were present in trace amounts, none above CR's level of concern. Two products had a nutrient above the upper limit for some of the ages they are sold for, which is a reason to check the dose, not to panic about a past bottle.

Why would a vitamin contain more than the label says?

Vitamins break down over time, so makers often add more at manufacture so the product still meets its label by the expiration date. FDA rules require added vitamins and minerals to be formulated to at least the labeled amount and allow reasonable excesses. Very large overages, such as vitamin C at 531% of the label, go well beyond the USP range for that nutrient. Vitamin B5 in gummies has no USP range.

Is a gummy better than a chewable?

In CR's results gummies were more often at or above their labels and chewables more often below. That says more about how these products hold up than about which format a child needs. Gummies are also the format most easily mistaken for sweets.

Do kids need vitamin D drops?

The American Academy of Pediatrics recommends 400 IU (10 mcg) a day for infants under 1 year, and a pediatrician may suggest a supplement for breastfed babies. For older children it recommends 600 IU (15 mcg) a day, which many get from fortified milk and food.
