If you’ve seen headlines about a magnesium glycinate recall in 2026, here’s what actually happened: on May 12, 2026, a company called Dkiru LLC recalled specific lots of Adndale Magnesium Glycinate Gummies, roughly 13,920 bottles, because they contained undeclared melatonin, an ingredient not listed on the label at all. The FDA classified it as a Class II recall, meaning exposure could cause temporary or medically reversible health effects, not life-threatening ones, but it’s still a real, documented case of a sleep supplement not containing what its label claimed. This sits alongside a broader, ongoing pattern independent testing organizations have flagged for years: some products labeled “magnesium glycinate” actually contain the cheaper “oxide” form instead, and separate independent lab testing in 2025 found detectable lead in magnesium glycinate products from multiple brands, including at least one major, well-regarded supplement company. This is educational information, not medical advice.
From the Practice
[RILEY: add a real observation here, for example how you help clients evaluate whether their specific magnesium brand is trustworthy, or a question you get repeatedly since this recall made news.]
What Actually Happened With the 2026 Recall
On May 12, 2026, Dkiru LLC recalled specific lots of Adndale Magnesium Glycinate Gummies (400 mg, sold in 90-count bottles) because they contained undeclared melatonin. The FDA’s enforcement report on this recall was published on June 18-19, 2026, and it was categorized as a Class II recall, the FDA’s designation for a situation where product exposure may cause temporary or medically reversible adverse health consequences, or where the probability of serious harm is remote.
The practical concern here is straightforward: someone taking magnesium glycinate specifically because they wanted a mineral, not a hormone, would have been unknowingly taking melatonin as well, which could compound sedative effects, particularly relevant for anyone also taking a separate melatonin supplement, prescription sleep medication, or other sedating substance without realizing they were effectively double-dosing.

This Isn’t an Isolated Incident, It’s Part of a Pattern
This is the part worth understanding beyond the single recall, since it points to a recurring, structural issue rather than a one-off mistake. Independent supplement testing organizations have repeatedly flagged that magnesium glycinate specifically is prone to a different kind of quality problem: some products marketed and labeled as “magnesium glycinate,” a specific chelated form of the mineral, actually contain magnesium oxide instead, a cheaper, less bioavailable form. In at least one documented case, a supplement company reportedly admitted to this substitution after independent testing raised the issue.
Separately, independent third-party lab testing conducted in 2025 tested multiple magnesium glycinate products, including capsules from a well-regarded national supplement brand, and found detectable levels of lead in the tested products. The tester noted this particular product tested positive for lead at a lower level than roughly half of the other magnesium products in their broader comparison, meaning even a “better than average” result in this space still meant detectable lead was present, not zero contamination.
Why Does This Keep Happening?
This comes back to a structural reality about how dietary supplements are regulated. Unlike prescription medications, dietary supplements in the US aren’t required to undergo FDA approval or pre-market testing to verify they contain exactly what the label claims, at the stated purity, before being sold. This is the same underlying regulatory gap that’s produced well-documented labeling accuracy problems with other sleep-related supplements, including melatonin, where independent testing has found similarly wide discrepancies between labeled and actual content, discussed in more detail in Melatonin Dosage. Magnesium glycinate isn’t uniquely troubled, it’s a visible example of an industry-wide quality-control gap.
What Actually Helps: Practical Steps
Given this pattern, a few concrete steps can meaningfully reduce your risk:
- Check for third-party testing certification. Look for seals from organizations like USP, NSF, or ConsumerLab specifically, these indicate independent verification of label accuracy, not just a manufacturer’s own claim.
- Check current recall listings before buying or continuing to use a product. The FDA maintains public enforcement reports, and independent organizations like ConsumerLab track recalls and warnings specifically for supplements.
- Be specifically cautious with gummies. Several of the most publicized supplement labeling and contamination issues, in magnesium and in melatonin, have involved gummy formulations specifically, worth factoring into your choice of product form.
- Don’t assume a well-known brand name guarantees purity. Independent lead testing in 2025 found detectable lead even in a product from a well-regarded national brand, brand reputation alone isn’t a substitute for checking actual test data.

What the Research Shows
A real, documented magnesium glycinate recall occurred in 2026 due to undeclared melatonin. The FDA classified this as a Class II recall affecting roughly 13,920 bottles, a concrete example of a labeling failure with a real potential for compounded sedative effects in unaware consumers.
Magnesium glycinate has a documented history of form-substitution issues beyond this single recall. Independent testing organizations have found some products labeled “glycinate” actually contain magnesium oxide, a cheaper and less bioavailable form, with at least one manufacturer reportedly acknowledging this after testing.
Independent lab testing has found detectable lead in magnesium glycinate products, including from well-regarded brands. 2025 testing found lead present across multiple tested products, illustrating that contamination risk isn’t limited to obscure or unknown manufacturers.
These quality issues reflect a structural gap in dietary supplement regulation, not isolated manufacturer failures.Because supplements don’t require pre-market FDA verification of label accuracy or purity, similar problems have been documented across other sleep-related supplement categories, including melatonin, making third-party testing verification a meaningfully protective step for consumers.

Frequently Asked Questions
What happened with the magnesium glycinate recall in 2026?
On May 12, 2026, Dkiru LLC recalled roughly 13,920 bottles of Adndale Magnesium Glycinate Gummies (400 mg) because they contained undeclared melatonin, an ingredient not listed on the label. The FDA classified it as a Class II recall, and the enforcement report was published in June 2026.
Is all magnesium glycinate affected by this recall?
No, this recall was specific to certain lots of one product, Adndale Magnesium Glycinate Gummies, manufactured by Dkiru LLC. That said, it’s part of a broader, documented pattern of quality issues across the magnesium supplement category, including form-substitution and contamination concerns with other brands.
How do I know if my magnesium glycinate actually contains glycinate and not a cheaper form?
Independent testing organizations have found some products labeled “magnesium glycinate” actually contain magnesium oxide instead. Checking for third-party testing certification (such as USP, NSF, or ConsumerLab verification) is the most reliable way to confirm a product contains what its label claims.
Has lead been found in magnesium glycinate supplements?
Yes. Independent third-party lab testing conducted in 2025 found detectable lead in magnesium glycinate products from multiple brands, including at least one well-regarded national supplement company, though at varying levels compared across products tested.
Why do supplement quality problems like this keep happening?
Dietary supplements in the US aren’t required to undergo FDA pre-market approval or testing to verify label accuracy or purity before being sold, unlike prescription medications. This regulatory gap has produced similar documented issues across other supplement categories, including melatonin, not just magnesium.
When to Work With a Sleep Consultant
Supplement quality issues like this recall are a real, recurring risk, not a rare fluke, and they’re a good reminder that what’s on the label isn’t always what’s in the bottle. If you want a sleep routine built on products you can actually trust, it’s worth getting guidance.
