Migliaccio & Rathod LLP is investigating whether magnesium gummy supplements are marketed in a way that misleads consumers about how much magnesium each serving provides.
Many magnesium gummies display a large milligram figure on the front of the package, such as “200 mg” or “400 mg.” That figure often refers to the weight of a magnesium compound, such as magnesium glycinate, rather than the amount of magnesium itself. The Supplement Facts panel on the back may disclose a much smaller amount of elemental magnesium.
In April 2026, the National Advertising Division (NAD) of BBB National Programs reviewed one such product. NAD found that a front-label claim of 200 mg could reasonably lead consumers to believe they were getting 200 mg of magnesium, when the product provided 22 mg per serving. NAD noted that even a literally true claim may convey a misleading message.
Consumers often choose magnesium supplements based primarily on dosage. If the front label creates a misleading impression of how much magnesium each serving contains, consumers may have paid more than they otherwise would have.
Potential concerns may include:
- Misleading dosage representations
- Front labels that conflict with Supplement Facts disclosures
- Price-premium injury
Signs You May Be Affected:
- You purchased magnesium gummies based on the milligram amount shown on the front of the package;
- You believed that figure was the amount of magnesium in each serving;
- The Supplement Facts panel lists a substantially lower amount of magnesium.
Potential Claims May Include:
- Violations of state consumer protection laws;
- False advertising;
- Breach of express and implied warranty;
- Unjust enrichment.
