If you live in the United States, you almost certainly know the brand GNC. The supplement store giant has over six thousand stores in America and locations in about fifty other countries.
There’s a good chance you already buy your supplements at GNC. If you’re like me, you might think twice about buying the generic whey protein that’s made by the supplement store.
I decided to put my assumptions to the test. Could GNC Pro Performance Whey actually be a great protein powder?
GNC Pro Performance Nutrition Info
One scoop delivers 140 calories: 24 grams of protein, 6 grams of fiber (1 gram of fiber and 2 grams of sugar) and 2 grams of fat (1 gram of saturated fat).
It’s relatively low in sodium with 3 percent of the recommended daily intake, but a little high in cholesterol with 20 percent of the RDI.
GNC Pro Performance Ingredients
The first ingredient is whey concentrate, which is cheaper and has more fat and carbs than whey isolate. This is probably why one serving has twice as many carbs compared to competitors like Optimum Nutrition Gold Standard and MusclePharm Combat Whey, which have whey isolate as the first ingredient.
So first on the ingredients label is whey concentrate, then whey isolate, then cocoa powder, natural flavors, cellulose gum (a thickener and stabilizer), soy lecithin (to improve mixability), xanthan gum, the artificial sweetener acesulfame potassium, sodium chloride (that’s just salt), and sucralose, also called Splenda®.
GNC Pro Performance Benefits and Effectiveness
There are no real shocks in this ingredients list, though it is a little unusual to have more acesulfame potassium (or Ace-K) than sucralose. It’s typically the last ingredient on a label and it’s one of the more controversial sweeteners you’ll find in a protein powder due to some (debatable) links between Ace-K and impaired insulin response.
It’s probably fine for you, but if you’re wary of it, most of its competitors contain it in lower doses.
Otherwise, it’s worth noting that GNC and Optimum Nutrition and Isopure all get their whey from Glanbia, one of the largest-scale producers of American style cheeses — whey can be a byproduct of cheesemaking, and Glanbia uses it to make protein supplements. So the quality of the whey itself should be on par with those more popular brands.
That said, there are a few things you might take issue with: GNC’s whey has the aforementioned artificial sweeteners, it contains soy (which some athletes worry can affect their hormones), and it has twice as many carbs as its “sister brands” Optimum Nutrition and Isopure.
On top of that, it doesn’t contain any digestive enzymes. Optimum Nutrition and most protein powders that contain whey concentrate include digestive enzymes like lactase and aminogen in their ingredients in order to reduce digestive issues among people with lactose sensitivities. (Whey isolates often don’t contain enzymes because they’re usually lactose-free.) If you have trouble with lactose, this might not be for you.
GNC Pro Performance Price
You can pick up a 1.96-pound tub of 25 servings for $20. That’s 80 cents per serving or 3.33 cents per gram of protein.
That’s very, very cheap. When looking at 2- or 3-pound tubs, it’s cheaper than MuscleTech’s Premium Gold (3.4 cents per gram of protein), MusclePharm’s Combat Whey (3.84 cents per gram), Isopure Low Carb (3.86 cents per gram) and Optimum Nutrition (4.31 cents per gram).
For a protein powder that contains whey isolate (which increases the price), it’s one of the cheapest on the market.
It dissolves quickly and easily, but it dissolved better in water than in milk. With milk, I found it was just a little grainy in parts.
GNC Pro Performance Taste
What’s unusual about this product is that it has no artificial flavors but it does have artificial sweeteners. The flavor, in the end, is very mild and reminds me of naturally sweetened protein powders like Xwerks and Muscle Feast: tasty with milk, bland with water.
This is a fine product that tastes great, mixes well, and is very, very cheap. It has the same issues a lot of cheaper protein powders in that it contains soy and artificial sweeteners, which you may want to avoid.
When compared to other cheap protein powders, the main difference is that it contains more whey concentrate than whey isolate, which increases the calories, carbs, and fat by a small amount. But if you can find room for them in your macros, it’s a pretty decent supplement.
