Our recommendation
Before starting this supplement, check with your healthcare provider to determine if you need additional calcium. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Take this supplement at a different time than these medications. Start with a low dose and monitor for any side effects like constipation or nausea [NIH ODS].
