Our assessment

The evidence shows that calcium is a critical mineral for your health, but it comes with important safety considerations. Our assessment is that you should prioritize getting calcium from food sources first, and only use supplements like this one to fill a verified gap in your diet. The data does not provide specific dosage information for this product, so you must follow the label instructions carefully.

How it works

Think of calcium as the building block for your skeleton. It works through bone mineralization to support bone density and mineral deposition, essentially keeping your frame strong [NIH ODS]. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after they fire [NIH ODS].

Safety profile

FDA received 592,059 total adverse event reports across all supplements, but specific report counts for this product are not available. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium in the 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]. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Start by evaluating your daily calcium intake from food. If you are not meeting the recommended amount, this supplement can help. Take it with food to improve absorption, and separate it from any of the listed medications by at least two hours [NIH ODS]. Do not exceed the dosage on the label, as the risks increase with higher intakes. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before starting [NIH ODS].
