Magnesium Glycinate 400 mg
Analysis updated October 2026 · How Scout scores
At a glance
Summary
This magnesium supplement uses magnesium glycinate, a highly bioavailable form that is well-absorbed and gentle on the stomach, which is a positive aspect. However, the presence of magnesium stearate, a common additive that may inhibit nutrient absorption, and several other processing agents like microcrystalline cellulose and maltodextrin, contribute to a moderate level of processing. While these additives are typical in supplements, they slightly detract from the overall formulation quality.
