GNC Pro Performance Amino 1000
Brand: GNC Pro Performance · Form: SUPPLEMENT FORM, OTHER [E0172] On Market
Our assessment
The evidence shows that GNC Pro Performance Amino 1000 contains calcium as its primary active ingredient. For general health, calcium is well-supported for bone mineralization and neuromuscular function [NIH ODS]. However, you should be aware that this product’s specific amino acid formulation is not detailed in the available data.
How it works
Calcium acts as a master regulator for your body. It supports bone density through mineral deposition and helps your muscles relax and nerves signal properly after exercise [NIH ODS]. This makes it a key player in recovery, though the product’s amino acid blend is not described in the data provided.
Safety profile
FDA received 592,059 total adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels can cause 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]. Calcium also reduces absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for the specific amino acid content of this product, so we cannot recommend it as a primary supplement. For calcium, you should not exceed the tolerable upper intake level without medical supervision. If you take any of the medications listed above, separate calcium intake by at least 2 hours [NIH ODS].
