Summary
This product is based on purified water, which is beneficial for hydration but lacks the natural purity of spring or glacial sources. The addition of minerals like calcium chloride and magnesium chloride enhances its nutritional profile, but the use of municipal water as a base results in a penalty. The absence of harmful contaminants is positive, but the processing involved in purification and mineral addition slightly reduces its overall score.
