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 in this product — coral calcium — does not offer proven benefits over standard calcium supplements. Our assessment: You should focus on meeting your calcium needs through food and standard supplements, as the data does not support unique advantages from coral calcium sources [NIH ODS].
How it works
Calcium is a master regulator for your body. It supports bone mineralization and density, and it helps with neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the key mineral your body uses to keep your skeleton strong and your muscles functioning properly.
Safety profile
Data not available for coral calcium specifically. However, for calcium in general, high 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]. FDA received 592,059 total adverse event reports for this product category [FDA data].
Our recommendation
Our recommendation: Get your calcium from dietary sources first. If you need a supplement, choose a standard calcium product with a known form (like calcium carbonate or citrate) and dosage. Talk to your doctor before starting, especially if you take medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, as calcium can reduce their absorption [NIH ODS].
