Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. For a general audience looking to support bone density, calcium is a well-established nutrient. However, the data indicates that high intakes may carry risks, so you should approach supplementation with caution [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling. Your body needs consistent amounts to maintain these critical functions [NIH ODS].
Safety profile
Data not available on specific side effect reports for this product. However, based on the ingredient data, high calcium intakes might increase the risk of heart disease and prostate cancer. High levels 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]. The total adverse event reports for all products in the FDA database is 592,059, but this number is not specific to this supplement [FDA data].
Our recommendation
Start by assessing your dietary calcium intake from food sources like dairy, leafy greens, and fortified foods. Do not exceed the tolerable upper intake level without medical supervision. Be aware that calcium can reduce the absorption of certain medications, including bisphosphonates and tetracycline antibiotics, so take it separately from those drugs [NIH ODS]. Consult your healthcare provider before starting this supplement.
