Our assessment
The evidence shows that NOW Full Spectrum Mineral Caps provides calcium, a mineral essential for bone health. However, you should be aware of the significant safety considerations associated with high calcium intake [NIH ODS].
How it works
Calcium acts as a master regulator for your body's structure and function. It supports bone mineralization and density, and is critical for neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
Data not available for this specific product's side effects. However, the FDA has received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium 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]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our assessment is that you should be cautious with calcium supplementation. Do not exceed the recommended dietary allowance without medical supervision. If you take any of the medications listed, separate your calcium dose by at least two hours or consult your doctor [NIH ODS].
