Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function. Our assessment: For most adults, meeting the recommended intake for calcium through diet is preferable, but supplementation can be helpful if you are not getting enough from food. However, the data does not provide specific dosing information for this particular product, so you should follow the label instructions carefully [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It supports bone density and mineral deposition, and it also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all products in this category. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very 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] [FDA data].
Our recommendation
We recommend you take this supplement exactly as directed on the label. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. If you take any of these, separate your doses by at least two hours [NIH ODS]. Start with the lowest effective dose and consult your healthcare provider before use, especially if you have a history of kidney stones or heart conditions.
