Our assessment
Our assessment: GNC Pro Performance Amino is a product that contains calcium, but the data does not provide specific dosage information for this ingredient. The evidence shows that calcium is essential for bone health, but the benefits depend entirely on your total daily intake from all sources [NIH ODS]. Without a specific amount on the label, you cannot reliably determine if this product contributes meaningfully to your daily needs.
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization, helping to maintain strong bone density, and it assists with neuromuscular relaxation, which is crucial for proper muscle relaxation and nerve signaling [NIH ODS]. Think of it as the structural component for your skeleton and a key signal for your muscles to function smoothly.
Safety profile
Data not available for this specific product. The FDA has received a total of 592,059 adverse event reports across all dietary supplements, but no specific side effects or report counts are linked directly to this GNC product in the data provided [FDA data]. However, for calcium in general, very high intakes can cause poor muscle tone, constipation, nausea, and abnormal heart rhythms [NIH ODS]. You should also be aware that calcium can reduce the absorption of medications like thyroid medication and certain antibiotics [NIH ODS].
Our recommendation
Our recommendation: Do not rely on this product as a primary calcium source unless the label provides a specific milligram amount. If you are taking any prescription medications, take this product at least two hours apart to avoid absorption issues [NIH ODS]. For general health, you should aim to meet your calcium needs through food sources first, and only use supplements when your diet falls short. Without a labeled dose, the value of this supplement is unclear.
