Pros

  • Incredible value for 180 servings
  • 400mg elemental dose in one capsule
  • Uses a blend of three magnesium types
  • Vegetarian-friendly capsule

Cons

  • Heavily relies on magnesium oxide
  • Lower systemic absorption than pure organic chelates

Warnings

  • High dose in a single capsule may cause digestive speed-up
  • Take with food to minimize stomach upset

Nutrient quality

86 Highest impact

The blend of three magnesium forms provides a robust total dose but relies significantly on less-absorbable oxide. A 400mg elemental level is effectively dosed to support systemic mineral requirements across several health goals.
