Frequently Asked Questions
Q. Why do I need a protein supplement?
A. Everyone should have all 20 amino acids available to the body through the bloodstream all of the time. If the body does not have
adequate amounts, it will break down muscle and other tissues to get the amino acids it needs for vital, life-sustaining functions −
this is known as a catabolic state. Protein is the best way to get all of the essential amino acids that the body needs. However, it can
be difficult for some people to get high-quality protein daily through whole foods alone. Supplementing can thus be a good option for these.
Even if you are able to get the sufficient amount of protein through your diet, protein-rich foods take time to digest and may be moderately
high in calories. If you are counting calories and require fast-digesting protein, you should consider a protein supplement.
Q. What is the difference between GNC Amp Gold Whey and other GNC whey protein supplements?
The main source of whey protein in GNC Amp Gold is Whey Protein Isolate (WPI). Isolate contains about 80-90% of protein gram-for-gram, is
fast-absorbing and has low fat with little to no lactose. Contrastingly, other whey protein
supplements may use Whey Protein Concentrate which contains about 70-80% protein. Thus, by only WPI, this supplement ensures that anyone
involved in fitness and training can get the purest protein that possible.
Q. How do I know whether I should be using the GNC Pro Performance protein supplements or the GNC Pro Performance Amp protein supplements?
The GNC Pro Performance range is for those whose goal is to stay fit, active, and healthy and who partake in light to moderate resistance
training. The Pro Performance Amp range is for those who prioritize increased strength, improved performance, and more muscles. These
individuals would partake in weight training, crossfit, or competitive sports.
Q. How is the real protein amount determined?
We at GNC guarantee that every one of our protein products contains the full amount of protein stated on the label and is 100% Real Protein with NO protein spiking.
- Determining the amount of real protein in a supplement comes down to accurate testing and measurement.
- To accurately calculate the amount of real protein in a protein supplement, the nitrogen from other ingredients such as amino acids, betaine and creatine, are subtracted from the total.
- Some companies use these ingredients to spike protein test results by not subtracting the nitrogen from these other sources.
- This practice is referred to as “protein spiking” or “amino spiking.” It is when ingredients that are not whole proteins are being used to spike protein test results.
- Many of these ingredients have a specific purpose and benefit, but they should not be counted as protein grams.
