Product Description

Thorne uses pure magnesium bisglycinate delivering 200 mg elemental magnesium per 2 capsules. The chelate form is well-tolerated and causes less GI upset than oxide forms.

What We Like

  • NSF Sport clearance for professional athletes
  • High bioavailability from chelate structure
  • Free from gluten, soy, and dairy
  • Capsules can be opened and mixed into drinks

What We’re Missing

  • Only 90 servings per container, no bulk sizes
  • Significantly more expensive than standard magnesium

Usage Recommendation

2 capsules in the evening before sleep or after intense training. If needed, open capsules and dissolve in warm water.
