GNC Pro Performance Amino Energy Advanced Fruit Punch

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health. However, based on the data provided, we cannot assess the specific benefits or risks of the GNC Pro Performance Amino Energy Advanced Fruit Punch formula itself, as the label and ingredients list are incomplete. For the calcium component, our assessment is that it supports bone density and muscle relaxation [NIH ODS].

How it works

Think of calcium as a key building block for your bones and a messenger for your nerves and muscles. It helps with bone mineralization, which is the process of depositing minerals into your bones to keep them strong [NIH ODS]. It also supports neuromuscular relaxation, meaning it helps your muscles relax and your nerves send signals properly [NIH ODS].

Safety profile

Data not available for the specific product's side effects. However, for the calcium ingredient, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available [FDA data].

Our recommendation

Because the full ingredient list and amounts for this product are not provided, we cannot make a specific recommendation for the GNC Pro Performance Amino Energy Advanced Fruit Punch. If you are taking calcium for bone health, you should be aware of potential interactions with medications and the risks of excessive intake [NIH ODS]. Consult your doctor or a pharmacist before starting any new supplement, especially if you take prescription medications.
