- Attorneys are actively investigating whether NOW Magnesium Citrate Softgels contain the amount and type of magnesium advertised on the product label.
This page was last reviewed and updated in September 2026 to reflect the latest case developments.
Why the math on the NOW Magnesium Citrate label matters
When it comes to supplements, magnesium is never sold in its pure form. Instead, it is combined with other substances to create compounds such as magnesium citrate, magnesium glycinate or magnesium malate. For example, 100 mg of magnesium citrate does not contain 100 mg of actual magnesium.
Each of these compounds contains a different percentage of actual magnesium:
- Magnesium citrate: 11.23% magnesium
- Magnesium glycinate: 14.10% magnesium
- Magnesium malate: 15.54% magnesium
The NOW Magnesium Citrate Softgels label states that each serving contains 2,018 mg of a blend of these three magnesium compounds. The label also indicates that this blend provides 400 mg of magnesium.
However, based on the percentages above, the numbers do not appear to add up. Even if the entire 2,018 mg blend were magnesium malate — the form that provides the most magnesium of the three — it would provide about 314 mg of magnesium, not 400 mg.
Because the label states that the blend also contains magnesium citrate and magnesium glycinate, which provide even less magnesium by weight, attorneys are investigating whether the product can provide the advertised 400 mg from the ingredients listed.
The Supplement Facts panel
What federal law says about supplement labels
Magnesium supplements and other dietary supplements do not need FDA approval before they are sold. However, that does not mean supplement companies can make any claims they want on their product labels. Companies are still required to follow federal labeling requirements.
These requirements are intended to give consumers accurate information about what a supplement contains. Product labels cannot contain false or misleading information, and the Supplement Facts panel must accurately state the amount of minerals, such as magnesium, in each serving.
As part of the NOW supplements lawsuit investigation, attorneys are examining whether the product’s claims about the amount and type of magnesium meet these federal labeling requirements.
