Our assessment

The evidence shows that calcium is a well-studied mineral, but it comes with important safety considerations.

Our assessment: you should be aware of the potential risks associated with high calcium intake, which include constipation, nausea, weight loss, and abnormal heart rhythms [NIH ODS].

How it works

Calcium acts as a master regulator for your body's structure and function. It supports bone mineralization, helping to build and maintain strong bones, and it plays a key role in neuromuscular relaxation, which is essential for proper muscle relaxation and nerve signaling [NIH ODS].

Safety profile

FDA has received 592,059 total adverse event reports. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high blood and urine levels 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

Based on the data, you should consult your healthcare provider before taking calcium supplements, especially if you have a history of kidney disease or heart conditions. Be mindful of the potential interactions with your medications. For the Natures Plus KalmAssure Magnesium Powder Unflavored, data for magnesium is not available in the provided section. You should always follow the label instructions and discuss any supplement regimen with a clinical pharmacist or your doctor [NIH ODS].
