Overview

Life Extension Magnesium Caps provide 500mg of elemental magnesium from three different forms: magnesium oxide (highest elemental content), magnesium citrate (well-absorbed), and magnesium succinate (Krebs cycle intermediate). This multi-form approach provides both high elemental magnesium content and good bioavailability. Life Extension is the longevity-focused supplement brand that has been at the forefront of anti-aging research since 1980, funding over $175 million in scientific research.

Our Verdict

8.0/10 — Very Good
