Our assessment
The evidence shows that this product provides a meaningful amount of calcium, which is essential for bone health. However, based on the FDA adverse event data, there are significant safety considerations you must be aware of. Our assessment is that this supplement can be beneficial for you if your dietary intake is low, but it requires careful dosing and medical supervision to avoid serious risks [NIH ODS] [FDA data].
How it works
Think of calcium as a structural building block for your skeleton. It works primarily through bone mineralization, supporting bone density and mineral deposition. Additionally, it plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports across all supplements, which includes data for calcium. For this specific ingredient, high intakes might increase your risk of heart disease and prostate cancer. 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] [FDA data].
Our recommendation
Start by assessing your daily calcium intake from food. Do not exceed the Tolerable Upper Intake Level without your doctor's guidance. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take calcium supplements at least two hours apart from these medications. We recommend you consult your healthcare provider before starting this supplement [NIH ODS].
