The category leaders deliver what the label says. A growing slice of brands is asking the format to carry doses it can't hold.
Gummies won the supplement aisle. They are the largest delivery format in the US, they turned “remember to take your vitamins” into “remember to eat your candy,” and on Amazon they own entire subcategories. Nothing about that is changing this year.
What is changing is what some brands are trying to put in them. The format was built for vitamins measured in micrograms and milligrams. The fastest growth is now in ingredients measured in grams — creatine, protein, greens — and in mega-dose claims a gummy cannot physically carry. The bill for that shift is showing up in lab results, in court filings and, since March 31, in Amazon’s listing rules. Most of the category is not the problem. In NOW’s vitamin C test, all five established brands passed, and the gummies Amazon shoppers click most are largely established brands with realistic claims. The gap is concentrated in a slice of brands, mostly newer and mostly chasing gram-dose or mega-dose claims. This report covers where gummy growth went, where the label gap shows up, and what the brands winning the category are doing differently.
SPINS data reported by NutraIngredients puts US gummy supplement sales at more than $4.88 billion for the 52 weeks ending September 6, 2026, across multi-outlet and natural channels. That is up from $4.48B the year before and $3.88B the year before that — roughly 9% growth, down from roughly 15% (our calculations). The format is still growing — at not much more than half the speed.
The biggest gummy segments are the ones the format was made for: multivitamins ($748.8M), children’s ($646.7M) and sleep ($591.8M). The fastest-growing are not. Protein and meal-replacement gummies grew 749%, green foods 144%, creatine 70% and pre-workout 67%. Those growth rates come off small bases — but every one of them is an ingredient dosed in grams.
Nutrition Business Journal’s 2025 format breakdown, via Nutraceuticals World, tells the same story from the other side. Gummies are 24.6% of a $72.88B US supplement market, the largest single format. Powders are 18.7% — and growing fastest, at 11%.
Creatine is where the tension is sharpest on Amazon (we covered the category in depth in June). SmartScout’s August data has “creatine gummies” at an estimated 260,000 monthly searches, with an estimated cost per click of $6.66 — against $1.15 for “creatine monohydrate.” The number of creatine gummy products in the US grew 59% between January 2025 and January 2026, according to Nutrition Integrated, yet gummies cost nearly three times as much per gram of creatine as powder, and only 2% of creatine gummies use a branded ingredient, against 26% of powders.
Amazon’s own Product Opportunity Explorer data — the 360 days to mid-October — shows two very different shelves. In the “creatine” niche, the 21 most-clicked products are all powders or capsules: not one gummy. Three listings (Nutricost and two Optimum Nutrition sizes) take about half of all clicks, almost every product launched before 2025, and ratings run 4.4 to 4.8 stars. Amazon Basics added its own creatine powder in February. In the “creatine gummies” niche, the top 65 products split clicks far more widely — the biggest single listing takes under 9%. Fifty of the 65 launched in 2025 or later and take 60% of clicks. Thirteen gummies rated below four stars hold 26% of clicks. And the price per labeled serving is several times higher: about $0.21–0.25 for the leading powders against roughly $1.60 for the leading gummies.
Search is still growing where the new buyer is. Over the same period, “creatine gummies” drew about 4.7 million searches on Amazon but grew less than 6% in the latest 90 days. “Creatine gummies for women” drew 1.2 million and grew 33% over 90 days and 62% over 180.
Protein gummies — the fastest-growing segment in the SPINS data — are almost entirely new on Amazon. Forty-nine of the 53 most-clicked products in Product Opportunity Explorer’s “protein gummies” niche launched in 2025 or later, and they take 86% of clicks. Most titles claim 10 to 20 grams of protein per serving. The same kind of product is listed across sports-nutrition, collagen, candy and fruit-snack categories — a supplement on one listing, a snack on the next — which is the line we looked at in August.
Put the niches side by side and the split is hard to miss. Where gummies carry the doses they were built for, the shelf is settled, dominated by established brands and well rated. Where they carry gram-dose ingredients, the shelf is new, crowded and less well rated.

The physics. A daily creatine dose is 3–5 grams. The creatine gummies NOW Foods tested in 2024 claimed between 250 and 1,700 mg per piece, which is why servings in that set ran from one to five gummies. Creatine also converts to creatinine in the presence of water, heat and acid — the exact conditions of a gummy cook, which often reaches 100°C or more. Vitamin C is destroyed by heat, and NOW measures gummy vitamin C losing around 20% a year on the shelf. Magnesium has a different problem: the compound is heavy. Magnesium glycinate is roughly 14% elemental magnesium by our calculation (forms vary), so “200 mg magnesium glycinate” is only a few dozen milligrams of actual magnesium.
The testing. When independent labs check, the high-dose and gram-dose gummies fail most often. In June 2026, NOW — which sells competing products — bought vitamin C gummies from 25 brands on Amazon, plus five legacy brands for comparison, and had them tested by HPLC at Alkemist Labs and in-house. Twelve of the 25 had almost no detectable vitamin C. All five products claiming 1,000 mg or more per gummy contained under 2 mg. All five legacy brands in the test passed. (NOW has run 24 of these testing rounds since 2017.)
Amazon’s own click data puts that in proportion. In Product Opportunity Explorer’s “vitamin C gummies” niche, the shelf shoppers actually click is dominated by long-established national brands with mid-range claims: Nature Made, Amazon Basics and Vitafusion account for roughly three-quarters of clicks among the top 21 products, with per-serving claims mostly between 250 and 1,000 mg and prices mostly under $15. The liposomal mega-dose segment is a sliver — two listings claiming 2,000 mg liposomal vitamin C hold about 2% of clicks, at roughly twice the price of the leaders. The label gap is concentrated in the long tail, and the long tail is where new brands launch.
Across three independent test rounds (NOW 2024, SuppCo 2025 and a UK-sourced Eurofins-tested round in 2025), 15 of 27 creatine gummy samples failed the tester’s label check, most with little or no creatine; all five powders SuppCo tested passed, at 98–101%. These rounds used different methods and samples, so read them as a pattern, not a market-wide failure rate.
The economics. Because actives degrade, gummy makers add overages — one formulator told SupplySide she has seen 20–60% — to stay at or above label through a typical two-year shelf life. That is expensive, and in our experience it is the first thing a cheap brand cuts.
The regulators, the competitors and the plaintiffs. FDA’s rule is stricter than most brands assume. For added vitamins, minerals and other added dietary ingredients, 21 CFR 101.36 applies the Class I standard: the product must test at no less than 100% of the declared amount. In September, scientists from FDA’s Office of Dietary Supplement Programs published a perspective on gummy manufacturing in the Journal of Dietary Supplements, stressing that label claims must hold through end of shelf life and that overages “should not be used to compensate for poor manufacturing practices.” An FDA spokesperson put it more bluntly: gummies “should not be treated simply as candy.”
The National Advertising Division got there first on magnesium. In April, on a challenge from competitor Pharmavite, it recommended Nature’s Truth stop claiming “200 mg magnesium per serving” on gummies whose Supplement Facts panel declared 22 mg; the advertiser agreed to comply.
The same ambiguity runs across Amazon’s magnesium gummy shelf. In Product Opportunity Explorer’s “magnesium glycinate gummies” niche, the established brands — Nature Made, Qunol, Vitafusion, Nature’s Bounty, Goli — state 100–125 mg of magnesium per serving in their titles; together they take about 29% of clicks among the top 30 products. Roughly 40% of clicks go to products whose titles headline 400 to 1,000 mg. A title alone does not say whether that figure is the compound or the elemental magnesium, which is exactly the question Amazon’s listing rule and the NAD decision turn on. For scale: if 1,000 mg meant elemental magnesium, it would take roughly seven grams of magnesium glycinate per serving (our calculation). The broader “magnesium glycinate” niche looks nothing like it: capsules dominate, only one gummy appears among the top 21 products, and just three of those 21 launched since 2025. Half the gummy shelf’s top 30 launched in that time. And the plaintiffs’ bar has found the format. In 2026 alone, class actions have targeted gummy dose shortfalls (Create Wellness creatine, which the company disputes), front-label doses that require multiple gummies (Target’s up&up ashwagandha, Vitamatic fiber), fiber and niacin shortfalls (Grüns greens), and “sugar-free” claims on gummies sweetened with allulose (Grüns, Goli). All are allegations, none decided. They are not fringe products: Goli’s Zero Sugar apple cider vinegar and ashwagandha gummies — part of the line the September suit targets — each draw about 11% of clicks in their Amazon niches.
Amazon. Since March 31, per its January seller notice as reported by PPC Land, Amazon has required that ingredient weights on supplement detail pages match the Supplement Facts panel exactly, and its third-party verification criteria, as quoted by testing labs, reference FDA’s nutrient tolerance rules. A title that says “1000mg” over a panel that says 500 mg per gummy is now a listing problem before it is a lab problem — and NOW’s vitamin C test found three products with “1000mg” in the name against a 500 mg per-gummy claim — whether that matches per serving depends on the panel.
They keep the claim inside the gummy. The vitamin C gummies that passed NOW’s test claimed 45–500 mg per gummy, most of them 125 mg. None of the mega-dose claims passed. A smaller number that holds through shelf life beats a bigger number that fails before expiry.
They state the dose the way the panel does. Per gummy and per serving side by side, with the gummy count next to the number. Elemental magnesium, not compound weight. The Target and Vitamatic suits are what happens when the front label does arithmetic the panel doesn’t.
They lead with verification. Legacy brands passed NOW’s round “with extra overages.” Create, even while disputing its lawsuit, says Eurofins tests every order, and it carries NSF Certified for Sport. Verification is becoming a conversion asset, not a back-office cost.
They move gram-dose ingredients out of gummies. Some creatine brands now sell lower-moisture chews rather than gummies. Soft chews grew 34% in SPINS’s 2025 data; powders are the fastest-growing format overall. The format decision is becoming a product strategy decision.
The brands doing this well show the format works. If you sell gummies on Amazon, the honest question is whether every listing says exactly what your panel says — and whether the gummy still says it on its last day of shelf life.
Audit every gummy ASIN against its Supplement Facts panel. Title, bullets, images and front-of-pack: per gummy versus per serving, compound versus elemental, and any number on the main image.
Ask your manufacturer for end-of-shelf-life data, not release COAs. Overage rationale, stability results, and a lab that has gummies in its validated method scope. An ISO 17025 certificate means little if the lab has not validated the gummy matrix.
Decide format before you decide flavor. For creatine, protein or high-dose vitamin C, price per gram, cost per click and lab risk may all point to a powder, chew or capsule.
Review “sugar-free” claims with counsel if your gummy uses allulose. The current suits argue it still counts as sugar for claim purposes.
Plan heat. If your ASIN is flagged as meltable, Amazon’s FBA window runs mid-October to mid-April. Check reviews for “melted” and “stuck together” either way — they are both a quality signal and a conversion leak.
If you want to see which of your listings no longer match your panel, Verid8 checks titles, bullets and images against Amazon’s supplement rules — start with a free listing scan. For a full catalog review of claims, certificates and margin, order an audit.
