GNC Pro Performance Amino 1000
Brand: GNC Pro Performance · Form: SOFTGEL CAPSULE [E0161]
Our assessment
The evidence shows that GNC Pro Performance Amino 1000 is a calcium supplement, not an amino acid product as the name might suggest. Based on the data provided, we can only assess the ingredient calcium. For general bone health, calcium is well-supported, but the data also notes serious potential risks associated with high intakes [NIH ODS].
How it works
Calcium works as a structural component for your bones and teeth, supporting bone mineralization and density. It also plays a role in neuromuscular relaxation, helping your muscles relax and nerves signal properly after contraction [NIH ODS].
Safety profile
Data not available for this specific product. However, for the ingredient calcium, the FDA has received a total of 592,059 adverse event reports across all supplements. The NIH ODS data warns that high calcium intakes might increase the risk of heart disease and prostate cancer. Side effects from high levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
Because the specific dosage of calcium in this product is not provided in the data, we cannot make a precise recommendation for GNC Pro Performance Amino 1000. If you choose to take a calcium supplement, be cautious about total daily intake from all sources. Calcium can reduce absorption of medications like bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your pharmacist or doctor to see if this product is appropriate for you.
