Solaray Magnesium Glycinate has the highest dose in our comparison: 350 mg of elemental magnesium from bisglycinate in four VegCaps, backed by in-house and independent testing in an NSF-certified GMP facility. It also adds BioPerine black pepper extract. Earth Energy gives a more moderate 275 mg in three capsules, with glycinate only.
