Our assessment
The evidence shows that this supplement contains calcium, a mineral essential for bone health. You should be aware that while calcium supports bone density, high intakes from supplements might increase the risk of heart disease and prostate cancer [NIH ODS]. FDA has received a total of 592,059 adverse event reports for this product category, though the specific number of reports linked to calcium alone is data not available [FDA data].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation by helping your muscles relax and your nerves signal properly [NIH ODS]. This makes it important for daily function and long-term bone strength.
Safety profile
High levels of calcium in your blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your dietary calcium intake before adding a supplement. You should consult your healthcare provider to determine if you need extra calcium, especially if you take any of the medications listed above. Choose a dose that aligns with your individual needs, and do not exceed the recommended daily allowance without medical guidance [NIH ODS].
