Nature's Answer Coral Calcium 1000 mg
Brand: Nature's Answer · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that coral calcium, at 1000 mg per serving, is primarily a source of the mineral calcium. Our assessment: for most people, standard calcium carbonate or citrate supplements are equally effective and often more affordable. The data does not support unique health benefits from coral calcium beyond what is provided by other calcium sources.
How it works
Calcium works as a master regulator for your body. It supports bone mineralization and density, and it helps your muscles relax and your nerves signal properly [NIH ODS]. You need adequate calcium daily to maintain these critical functions.
Safety profile
FDA received a total of 592,059 adverse event reports for this product category. Specific side effects from high calcium intake include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [FDA data] [NIH ODS]. Some research also 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, and low phosphate levels [NIH ODS].
Our recommendation
If you need a calcium supplement, choose a standard product from a reputable brand. Be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Do not exceed the recommended daily intake without consulting your doctor. Data not available for specific coral calcium benefits beyond standard calcium.
