Direct answer: Compare calcium supplements by elemental calcium per serving, citrate versus carbonate, dose size, meal instructions, tolerance, and fit with the complete daily target.
Calcium citrate and carbonate
- ASMBS guidance favors calcium citrate after bariatric surgery; citrate may be taken with or without meals.
- Calcium carbonate should be taken with meals and provides more elemental calcium by weight.
- For sleeve gastrectomy, prevention guidance commonly uses 1,200–1,500 mg of elemental calcium daily from all sources in divided doses.
- Keep supplemental calcium apart from iron according to the care team's instructions.
What to do next
Do not choose from the front-label milligrams alone. Confirm whether the number is elemental calcium and how many tablets or chews make a full dose.
For procedure-specific supplement amounts, use the ASMBS guideline summary and compare the complete regimen with the plan from the bariatric surgeon or registered dietitian.
