Our assessment
The evidence shows that GNC Pro Performance Amino 1000 contains calcium as its primary active ingredient. Our assessment is that calcium is essential for bone health and nerve function, but the specific benefits of this product depend entirely on whether you are meeting your daily calcium needs through diet. Data on this specific product's efficacy is not available beyond the ingredient profile.
How it works
Think of calcium as a building block and a signal. It supports bone mineralization, helping to deposit minerals into your skeleton for density and strength. It also plays a key role in neuromuscular relaxation, allowing your muscles to relax and nerves to signal properly after activity [NIH ODS]. This mechanism is why calcium is often linked to both bone health and muscle function.
Safety profile
Safety data for this specific product is not available. However, for the ingredient calcium, FDA has received 592,059 total adverse event reports across all products. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive calcium include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Start by assessing your dietary calcium intake before adding this supplement. Most adults get enough calcium from food. If you choose to use this product, take it with meals and separate it from any medications by at least two hours. Do not exceed the daily tolerable upper intake level for calcium without medical supervision. For specific dosing, consult your healthcare provider, as data on the optimal serving for this product is not available [NIH ODS].
