Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function. Our assessment is that calcium is a well-researched supplement, but you need to be precise about your dosage and timing to avoid potential risks and interactions [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineralization, and it also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
Data not available for specific side effect counts for this product. However, FDA received 592,059 total adverse event reports across all supplement categories. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. 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
Start by checking your total daily calcium intake from food and other supplements. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should take this supplement at a separate time from those medications. Given the potential for serious side effects at high doses, do not exceed the recommended dose on the label without consulting your doctor [NIH ODS].
