Swanson Coral Calcium Complex
Brand: Swanson · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that calcium is essential for bone health, but the benefits of a coral calcium complex are not supported by unique data beyond standard calcium sources. You should understand that this product provides calcium, and the data on its specific form is not available [NIH ODS].
How it works
Think of calcium as a structural builder — it supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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] [FDA data]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start with your dietary calcium intake first. If you need a supplement, choose a standard calcium product with a clear dose. Data not available for coral calcium specifically. Take calcium separately from thyroid medication or antibiotics [NIH ODS].
