Source Naturals Magnesium Malate 90 Tabs
Analysis updated August 2026 · How Scout scores
At a glance
Summary
This magnesium supplement contains several additives such as stearic acid, acacia gum, and modified cellulose gum, which are common in tablet formulations but contribute to a moderate level of processing. While these ingredients are not harmful, they do not enhance the supplement's nutritional value. The absence of artificial sweeteners, dyes, or seed oils is positive, but the formulation lacks the high-quality, bioavailable forms of magnesium that would elevate its score.
