Calcium palmitate combines the mineral calcium with palmitic acid, a saturated fat. Some supplements and fortified foods include it as a calcium source. Very little research compares how well this form absorbs or how comfortable it is on the stomach versus common forms like calcium citrate or calcium carbonate. No clear evidence shows it works better than those options.
Take calcium palmitate with food. Eating stimulates stomach acid, which aids absorption and can cut down on stomach upset. Elemental calcium levels differ from product to product, so follow the label. Also tally your total daily calcium from food and any other supplements you take.
High calcium intake can raise kidney stone risk in people who are prone to them. These supplements can also block the absorption of some antibiotics (like tetracyclines and quinolones) and thyroid medications. Talk to your doctor before you start if you have kidney problems or take prescription drugs.
