Product Information

📋 Directions for Use

Suggested Usage: Mix 1 level teaspoon of powder into at least 8 oz. of cold water or clear liquid until fully dissolved. To fully dissolve, add powder slowly while stirring. Once prepared, this mixture may be added to smoothies or juices as desired. Take once daily with a meal. Pure magnesium citrate powder can increase the temperature of liquids upon contact; therefore, the recommended serving MUST be mixed into at least 8 oz. of cold liquid to neutralize this reaction prior to ingestion.

🧪 Formulation Notes

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.
