  • Carbonated soft drinks including diet sodas contain Phosphoric Acid, which interferes with Calcium absorbtion; as a result most of the Calcium ingested in the diet is passed through in the urine.
  • exercise in combination with adequate Calcium intake is the ideal combination to help lay down strong bone in growing children.
  • Taking calcium with food in dosages of 500 mg or less increases absorption.
  • Calcium Citrate is absorbed better than Calcium Carbonate.
  • Read labels and purchase foods with added Calcium
