Additional notes

"Why it is here: To fill a measured gap between your usual food calcium and your target, not to supply the whole target. How to take: With or without food. Published evidence: Calcium citrate is 21% calcium by weight and is less dependent on stomach acid than calcium carbonate. Absorption is highest at 500 mg or less per dose and falls as single doses get larger. Clinical experience (observation): Calcium citrate is my preferred form. In my practice, patients taking it have had fewer complaints and side effects. Caution: Each capsule supplies 150 mg of elemental calcium. Keep each dose to 3 capsules (450 mg) or fewer, and count calcium from every source, including multivitamins and antacids. Calcium can interfere with levothyroxine, bisphosphonates, iron, and some antibiotics; ask your pharmacist about spacing. Review: Once or twice a year, or when your diet, a diagnosis, or your medicines change, ask whether this supplement is still filling a measured gap."
