Study Summary
This study has two research arms: The purpose of the 1st is to determine if a smaller particle size calcium carbonate supplement (than that which is now commercially available) improves calcium absorption and retention in adolescents girls. The purpose of the 2nd is to determine if vitamin D supplementation improves calcium absorption and retention in adolescents girls.
Primary Outcome
Total calcium(Ca) retention will be calculated - Ca retention/d = Ca intake/d - Ca excretion/d (urine + feces)
