Gummy Vitamins: What FDA Scientists Want You to Know

Gummies have grown from a children's novelty into one of the largest supplement formats. In September 2026, FDA scientists published a perspective on the challenges of making and testing them, with a clear message: a gummy supplement should not be treated simply as candy [1][2]. Delivering the labeled amount from the first gummy to the expiration date is a real formulation challenge.

A Short History of the Supplement Gummy

According to NutraIngredients [1]:

• Late 1990s: The modern gummy supplement arrives with Yummy Bears from California-based Hero Nutritionals, after a two-year R&D effort to mask flavors, keep nutrients stable, and control texture and moisture.
• By 2017: Adults make up about 65% of the gummy supplement market.
• 2020 onward: The COVID-19 era adds momentum, as shoppers look for immune support and everyday self-care.
• 2024 to 2026: SPINS figures climb from $3.88 billion (2024) to $4.48 billion (2025) to more than $4.88 billion (52 weeks ending Sept. 6, 2026). Multivitamins ($748.8 million), children's supplements ($646.7 million), and sleep ($591.8 million) lead the way.

The law that governs supplements, the Dietary Supplement Health and Education Act of 1994, never required any particular dosage form. FDA scientists even describe the gummy as "an example of an innovative dosage format" [1].

How Gummies Are Made: The Gummy Matrix

FDA scientists describe a gummy as a matrix: a network of gelling agents, sugars, acids, and moisture [1]. The gelling agent may be gelatin, pectin, agar, or starch, and the vitamin or botanical has to be spread evenly through that structure and stay intact.

Several steps can work against the nutrient:

• Heat. The candy base is cooked. Some ingredients can break down while the matrix is heated [1].
• Water. Gummies can have higher water activity, which may make a product more vulnerable to microbes [1].
• Acidity and humidity. The FDA team names acidity, temperature, humidity, equipment, and moisture content as critical factors in the process [1].
• Stickiness. Even testing is harder. A sticky gel network can complicate lab analysis, and methods may need to be modified for gummies [1].

There is no single perfect gummy base for every ingredient, the FDA scientists wrote [1]. Different ingredients can call for different bases, amounts, and gelling processes [1].

The "overage" problem

Because some nutrients fade over time, manufacturers may add a little extra at the start (an "overage") so the product still meets its label claim at expiration. The FDA scientists accept that, with a firm limit: overages "must be constrained by safety considerations and should not be used to compensate for poor manufacturing practices" [1]. They point to newer tools, such as encapsulation techniques and heat-resistant microbial strains, as ways to need fewer overages [1].

What Independent Testing Has Found

The clearest peer-reviewed data come from melatonin.

In a research letter in JAMA, Cohen and colleagues bought 25 melatonin gummy products sold in the U.S. and measured what was actually inside [3]:

• 22 of 25 products (88%) were inaccurately labeled. Only 3 were within ±10% of the declared amount.
• In products that contained melatonin, the measured amount ranged from 74% to 347% of the labeled quantity.
• One product had no detectable melatonin but did contain 31.3 mg of CBD.

The authors were clear about the limits: the sample was small, only one sample per brand was tested, and the results may not apply to tablets, capsules, or other batches [3]. Still, it shows how much a gummy can drift from its label.

Industry is testing too. NOW Foods reported that it tested 25 vitamin C gummies bought on Amazon and that only 13 met their label claim, according to NutraIngredients [1]. That testing was done by a company, not published in a peer-reviewed journal, so it is a useful signal rather than settled science.

Can Gummies Deliver Their Nutrients?

When a gummy is well made, the format itself does not appear to be the problem.

• Vitamin D3. In a crossover study, healthy adults took a single 20,000 IU dose of vitamin D3 as either gummies or tablets, then switched. In the larger study (31 adults), blood vitamin D3 exposure (area under the curve) was higher with the gummies: 1,474 vs. 774 ng·h/mL [4]. The study was funded by an unrestricted grant from Church & Dwight, a gummy maker [4].
• Vitamin C. In a randomized crossover trial of 30 adults, a 1,000 mg vitamin C gummy and a 1,000 mg caplet showed similar absorption and were considered bioequivalent [5]. Four of the six authors worked for Church & Dwight, the maker of the tested gummy [5].

Both studies tested specific branded products and were industry-linked, so they tell us what a well-made gummy can do, not what every gummy does. As the FDA scientists note, quality depends on the maker [2].

Why This Matters at Home: Gummies and Kids

Because gummies taste like candy, storage matters. CDC researchers estimated about 10,930 emergency department visits for unsupervised melatonin ingestion by children aged 5 and under from 2019 to 2022 [7]. Gummies were the most commonly documented dosage form (47.3% of visits), and most visits (93.5%) did not lead to hospitalization [7]. Poison center calls for pediatric melatonin ingestions rose 530% from 2012 to 2021 [6].

The CDC's advice applies to every supplement, not just melatonin: keep all medicines and supplements, including gummies, up and away, out of children's reach and sight [7]. Child-resistant packaging is worth choosing in homes with young children [7].

What Researchers Are Still Asking

• How common are label gaps across gummy types? The JAMA study covered only melatonin and tested one sample per brand [3]. Broader, multi-batch testing of other gummy categories is still needed.
• Which gummy bases suit which ingredients? FDA scientists say there is no single perfect base, and they call for fit-for-purpose formulation and validated testing methods [1, 2].
• Can new technology cut overages? Encapsulation and heat-resistant strains are promising, but the FDA team frames them as areas of novel formulation, not solved problems [1, 2].
• Will guidance change behavior? NOW Foods called the FDA perspective "a valuable starting point" but argued that enforcement against bad actors is what will drive real improvement [1].

How to Choose a Quality Gummy

Under federal law, supplement companies are responsible for making sure their products are safe and properly labeled before they reach the market. FDA can act against adulterated or misbranded products after they are sold [8]. A practical checklist:

1. Be skeptical of mega-doses in tiny gummies. In NOW's testing, as reported by NutraIngredients, the five vitamin C gummies claiming 1,000 mg or more per gummy each contained less than 2 mg [1]. If a number seems too big for a small gummy, ask questions.
2. Buy from brands with a real business presence. NOW described some marketplace sellers as transient companies operating through P.O. boxes [1].
3. Check the expiration date and storage directions. Heat and humidity matter for gummies [1]. Keep the lid tight and store them somewhere cool and dry.
4. Read the whole label. Look at the serving size (often two or more gummies), added sugars, and any extra ingredients.
5. Store them like medicine, not candy. Up and away, out of children's reach and sight [7].
6. Consider other formats when precision matters. If you need an exact amount of a nutrient, ask your healthcare professional whether a capsule, softgel, or tablet makes more sense.

Frequently Asked Questions

Are gummy vitamins as effective as pills? They can be. Industry-funded trials found that specific vitamin D3 and vitamin C gummies were absorbed at least as well as tablets or caplets [4, 5]. But results depend on how each product is made, and label-accuracy testing shows quality varies [2, 3].

Why would a gummy contain more than the label says? Manufacturers sometimes add extra (an overage) to make up for nutrient loss over shelf life. FDA scientists say overages must be limited by safety and should never cover for poor manufacturing [1].

Does the FDA approve gummy supplements before they're sold? No. Companies are responsible for the safety and labeling of their products before marketing, and FDA can take action against adulterated or misbranded products once they're on the market [8].

Are gummies safe for kids? Only use products and amounts made for children, and talk with your child's healthcare provider first. Always store gummies out of reach; flavored products, including gummies, show up often in CDC data on unsupervised melatonin ingestion in young children [7].

A Note on NUTRIO Gummies

NUTRIO makes gummy supplements, and like every NUTRIO product, they are third-party tested.

The Bottom Line

Well-made gummies can deliver their nutrients, but label-accuracy testing shows quality varies widely [3][4][5]. FDA scientists describe the gummy as a complex product that needs careful formulation, validated testing, and accurate labels [1][2]. Choose brands that test their products, check serving sizes and storage directions, and keep gummies out of children's reach.
