At a glance
Summary
This magnesium supplement contains magnesium oxide, which is a cost-effective but less bioavailable form of magnesium. The presence of carrageenan, a controversial thickening agent linked to potential digestive issues, and lecithin, a processed emulsifier, slightly detracts from its overall quality. While the formulation is functional, the inclusion of these additives impacts its rating.
