Our assessment
Our assessment: The evidence for this product is based on its single ingredient, calcium. Calcium is essential for bone health and muscle function, but the data does not support using it without medical need. You should not rely on this supplement without first evaluating your dietary calcium intake [NIH ODS].
How it works
Calcium acts as a master regulator for your bones and nerves. It supports bone mineralization and density, while also helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
The FDA received 592,059 total adverse event reports across all supplements, but specific report counts for calcium alone are not available. Data shows that high calcium intake may increase the risk of heart disease and prostate cancer. High levels in the blood can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS]. Calcium can also reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you get your calcium from food first. If you do need a supplement, keep total intake from all sources below the upper limit. Always take calcium supplements separately from other medications by at least 2 hours [NIH ODS].
