Our assessment
The evidence shows that calcium is essential for bone health, but the specific form in GNC Coral Calcium does not provide proven advantages over standard calcium supplements. The data confirms that calcium supports bone mineralization and neuromuscular function [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It works by depositing into bone tissue to maintain density and also helps your muscles relax and nerves send signals properly [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports across all products. High calcium intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive intake include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. High levels in blood and urine can also cause poor muscle tone, poor kidney function, and low phosphate levels [NIH ODS].
Our recommendation
Start by assessing your total calcium intake from food before supplementing. Be aware that calcium can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for specific coral calcium benefits. Talk to your doctor to determine if a standard calcium supplement is right for your needs.
