Our assessment

Our assessment: The evidence shows that Chief Originals Magnesium Comfort contains calcium, and while calcium is essential for bone health, you need to be aware of specific risks and interactions. The data does not provide a specific dosage of calcium in this product, so we cannot confirm how much you are getting per serving [NIH ODS].

How it works

Think of calcium as a key structural component for your skeleton. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS].

Safety profile

FDA has received 592,059 total adverse event reports across all supplements, though specific reports for this product are not available. High calcium intakes might increase the risk of heart disease and prostate cancer. Very high levels in the blood can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].

Our recommendation

Our recommendation: Since the exact calcium content is not provided on the label, data not available for a precise dose. If you are taking calcium supplements from other sources, be cautious about total intake. You should also be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your pharmacist or doctor to review your total calcium intake and medication schedule.
