Is AdvaCAL more effective with added magnesium?
Not necessarily. A study published in the 1999 American Journal of Nutrition suggests that the bone benefit of magnesium results from its alkalinity (i.e. high pH). Because the AAACa calcium in AdvaCAL is already highly alkaline, it likely offers the same alkalinity bone benefit as magnesium.* Those who desire to take magnesium with their AdvaCAL should use AdvaCAL Ultra 1000 which contains 600 mg of magnesium per daily serving.
