NOW Coral Calcium 1,000 mg
Brand: NOW · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium is essential for bone health, but the specific form found in NOW Coral Calcium 1,000 mg does not offer unique benefits over standard calcium supplements. Our assessment is that this product provides 1,000 mg of calcium, which is a significant dose, but you should be aware of the potential risks and interactions associated with high calcium intake.
How it works
Calcium is a mineral that acts as a critical building block for your bones. It supports bone mineralization and density, and also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the primary structural material for your skeleton and a regulator for your muscles and nerves.
Safety profile
Data not available for NOW Coral Calcium specifically. However, for calcium in general, the FDA has received a total of 592,059 adverse event reports across all products. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium in the blood and urine 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].
Our recommendation
We recommend you consider your total daily calcium intake from all sources before taking this supplement. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult with your healthcare provider to determine if this supplement is appropriate for your specific needs and to ensure it does not interfere with any medications you are taking.
