Nora Ross Okinawa Coral Calcium

Our assessment

The evidence shows that Nora Ross Okinawa Coral Calcium is a calcium supplement, and calcium is a mineral essential for bone health. However, the specific claims about "coral calcium" are not supported by unique data in the provided information. Our assessment is that you should focus on the well-documented benefits and risks of calcium supplementation, not on the source of the calcium [NIH ODS].

How it works

Think of calcium as a key structural component for your bones. It supports bone density and mineral deposition, which is critical for maintaining strong bones as you age. It also plays a role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS].

Safety profile

The FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from very high calcium levels in the blood and urine include 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 several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

If you choose to take this supplement, be aware that your total calcium intake from food and supplements should not exceed the upper limits established by experts. Data not available on the exact dosage per serving from the provided information. Because of the potential interactions and risks, we recommend you discuss this supplement with your doctor, especially if you take any medications listed above [NIH ODS].
