About Douglas Labs - Magnesium Glycinate 240 capsules

Douglas Labs Magnesium Glycinate delivers elemental magnesium bound to glycine, a chelated form associated with enhanced absorption and gentle gastrointestinal tolerability compared to oxide or sulfate forms. This practitioner-grade formulation supports muscle relaxation, restful sleep, and healthy nervous system function. It's designed for adults seeking a well-tolerated magnesium supplement for daily use.

Why It's Worth Considering: Douglas Labs formulates to practitioner standards, and the glycinate chelate is a preferred form among clinicians for patients who need higher magnesium intake without digestive discomfort.
