Magnesium is a mineral that is critical for energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization. It is a required cofactor for an estimated 300 enzymes. Among the reactions catalyzed by these enzymes are fatty acid synthesis, protein synthesis, and glucose metabolism. Magnesium status is also important for regulation of calcium balance through its effects on the parathyroid gland.

Suggested Use

Mix 1/4 level teaspoon of powder into at least 6 oz. of cold water or clear liquid. Take once daily with a meal. Pure Magnesium Oxide Powder can increase the temperature of liquids upon contact; therefore, the recommended serving must be mixed into at least 6 oz. of cold liquid to neutralize this reaction prior to ingestion.

Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.


Store in a cool, dry place after opening.
