Nature's Plus Activated Coral Calcium
Brand: Nature's Plus · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium is essential for your bone health, but the form in this supplement—coral calcium—does not offer unique benefits over standard calcium carbonate. Our assessment: you can meet your calcium needs with more conventional supplements, and you should be aware of potential risks at high intakes [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It supports bone density and mineral deposition, which is critical for preventing fractures as you age. Calcium also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes can cause constipation, nausea, and weight loss. More serious risks include poor kidney function, abnormal heart rhythms, and a higher risk of death from heart disease. High calcium levels in the blood can also lead to extreme tiredness and frequent need to urinate [NIH ODS] [FDA data]. Note: Data on the exact number of reports specific to coral calcium is not available.
Our recommendation
We do not recommend Nature's Plus Activated Coral Calcium over standard calcium supplements. If you choose to take calcium, aim for 1,000–1,200 mg daily from all sources, and be cautious with dosing. Calcium can reduce absorption of medications like bisphosphonates, thyroid medication, and certain antibiotics, so take it at a separate time from those drugs [NIH ODS].
