420 mg

Other ingredients: citric acid, potassium bicarbonate, natural lemon flavor, modified food starch.

Dosage and Use
  • Take 1/2 to 1 scoop daily, preferably in the evening. If loose bowels or diarrhea occurs, simply reduce dose until bowel movements are normal.
  • How to make a drink: Add 2-3 ounces of boiling water (preferably spring, filtered, or distilled) per scoop, and stir until dissolved. Add cold water if desired, or drink as a hot tea.

Though the magnesium citrate dissolves, a small portion of the natural lemon flavoring may not dissolve completely. This is normal.
