NOW Coral Calcium Plus
Brand: NOW · Form: CAPSULE [E0159]
Our assessment
The evidence shows that NOW Coral Calcium Plus is a source of the essential mineral calcium, which plays a critical role in bone health. However, the data requires a careful look at both benefits and risks before you decide to use it [NIH ODS].
How it works
Calcium functions as a key structural component for your bones. It supports bone mineralization and density, and it is also essential for neuromuscular relaxation and nerve signaling. Think of it as the raw material your body uses to keep your skeleton strong and your muscles functioning properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for products in this category, though data for this specific product is not available [FDA data]. Be aware that high calcium intake may increase the risk of heart disease and prostate cancer. Very high levels in the blood and urine 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 [NIH ODS]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Before taking this supplement, we recommend you evaluate your total daily calcium intake from all sources, including food. If you are on any prescription medications, take them at a different time of day than the calcium supplement to avoid absorption issues. Consult your healthcare provider to determine if supplementation is right for you, especially given the potential risks at high intakes [NIH ODS].
