Dicalcium phosphate combines calcium with phosphorus in one salt. Each gram supplies roughly 230 mg of calcium and 180 mg of phosphorus. Many people who need to boost both minerals choose this form because it adds phosphorus that plain calcium carbonate or citrate does not provide. Take it with food to improve absorption.
Separate it from certain antibiotics and thyroid medicines by at least two hours. Calcium can bind those drugs and reduce how much your body absorbs. If you have kidney problems or take other supplements, ask a healthcare professional before starting. High doses of either mineral can be harmful when kidneys do not filter properly.
