Our assessment
The evidence shows that calcium is essential for bone health, but it is the ingredient in this product that requires careful consideration. Our assessment: Calcium is a critical mineral for bone mineralization and neuromuscular relaxation [NIH ODS]. However, the data indicates that high calcium intakes might increase the risk of heart disease and prostate cancer, and high levels in the blood and urine can cause serious health issues [NIH ODS].
How it works
Calcium acts as a master regulator for your body's foundation. It supports bone density and mineral deposition, and it also plays a key role in muscle relaxation and nerve signaling [NIH ODS]. Think of it as the building block for your skeleton and a calming influence on your nervous system.
Safety profile
Data not available for this specific product's adverse events. General data shows a total of 592,059 adverse event reports for this ingredient category [FDA data]. Known side effects from high calcium levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: You should be aware of your total calcium intake from both food and supplements. Do not exceed the Tolerable Upper Intake Level without medical supervision, and be mindful of the serious risks associated with high levels [NIH ODS]. If you take any of the listed medications, take calcium at a different time of day to avoid absorption issues [NIH ODS].
