Analysis

While magnesium oxide is less absorbed than organic chelates, its high elemental yield makes it a very efficient way to pack 400mg into a single softgel. The softgel format can be easier to swallow for people who dislike dry tablets.

It is an ideal fit for someone looking for an easy-to-find, budget-friendly magnesium supplement for basic mineral status. It also works effectively for those who need a mild digestive aid to support regularity.

Pros

  • Full 400mg dose in one softgel
  • Softgel format is easier to swallow
  • Excellent price for 150 servings
  • Reputable and widely trusted brand

Cons

  • Magnesium oxide has the lowest systemic absorption
  • May cause digestive upset for sensitive individuals
  • Contains soy and bovine gelatin

Warnings

  • Avoid if you have a soy allergy
  • Expect a mild laxative effect from the oxide form
