Our assessment
Our assessment: The evidence shows that calcium is a critical mineral for bone health, but it must be used with careful attention to dosing and medication timing. For most adults, the goal is to meet — not exceed — the recommended intake through diet and supplements [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation by helping your muscles and nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, very high intakes may lead to poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Additionally, some research suggests high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Start by assessing your dietary calcium intake before adding a supplement. If you take calcium, be aware that it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Space your calcium supplement at least two hours apart from these medications. Data not available for specific dosing recommendations for this product.
