Our assessment
The evidence shows that calcium is essential for bone health, and this product provides a foundational mineral for your skeleton. However, the data reveals important safety considerations you need to know before taking a calcium supplement. Our assessment: this supplement can be beneficial if you have a confirmed low dietary intake, but it is not for everyone [NIH ODS].
How it works
Think of calcium as the primary building block for your bones. It works through bone mineralization, directly supporting bone density and the deposition of minerals into your skeleton. Additionally, it 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 for products in this category. The data shows high intakes of calcium might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high levels in the blood and urine include 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by evaluating your dietary calcium intake before adding a supplement. If you take this product, be aware of the potential interactions with common medications and the serious side effects from excessive intake. We recommend consulting your healthcare provider to check your calcium levels and ensure this supplement is safe and appropriate for you [NIH ODS].
