Why we rated GNC Pure Isolate our #4

Contains only micro-filtered Whey Isolate, meaning it's very quick and easy to digest

Most diverse BCAA components of any protein on this list

Very low price per serving, making it a good value


GNC Pure Isolate Protein Powder

We were really excited to dive deeper into this brand of protein. It’s the second-best-selling protein at GNC, and pretty cheap for an entire container. GNC has a great public perception, so we were curious to see if it could stand up next to its competition on a granular level.

What’s in GNC Pure Isolate?

GNC Pure Isolate is unique in that the powder is made up almost entirely of whey isolate. Whey isolate is a quick-release and fast-absorbing form of protein that aids in muscle growth and performance. To add to this, their whey isolate is micro-filtered, which enhances its ability to be absorbed effectively by the body. When my SO and I tried this powder out, we noticed that it was extremely easy on the gut, probably because of the micro-filtering process that it went through.

In one serving of GNC Pure Isolate, there are 25 grams of protein and 5 grams of BCAAs. This is a great amount of protein for the value of each scoop, which falls just below a dollar. The BCAA profile in this protein powder is also the biggest and has the best variety of any other protein on this list.

Unfortunately, like many of the other protein powders on this list, it does contain soy and sucralose (aka. Splenda). Soy is an allergen that seems to be omnipresent, but it’s really important to try to avoid, especially for men. Since soy contains plant estrogens that closely mimic the human body’s naturally-occurring estrogen hormones, these plant estrogens can wreak havoc on the body’s natural hormone balance. In men, this can look like infertility, gynecomastia, or erectile dysfunction. Sucralose is linked to an increased risk of cancer (study link: https://pubmed.ncbi.nlm.nih.gov/27078173/) though more studies are needed to confirm this.

GNC Pure Isolate also is made up of almost exclusively milk ingredients, so it is not recommended for those with dairy allergies, or those that choose to stay away from dairy.

What Are the Flavors Like?

The few flavors that GNC offers with this protein powder are not super original, like some of the other powders in this list, but most of them taste great. My SO thought that the Vanilla Custard flavor was way too sweet, which I have to agree with; but our favorite was the Cookies and Cream flavor.

Though the flavors are good for the most part, we can’t get over that there are only 4 options. We also think that it’s important to note that the texture and mixing ability of this protein powder was the worst of the 5 on this list. While it wasn’t “bad” per se, we have just reviewed several others that mix much better than this one.

The Bottom Line

This protein powder was made for those that want a fast, easy way to fuel their body and aid the generation of muscle mass immediately before or after an intense workout. The value of this powder is great: less than $1 per serving and one of the better ones on this comparison list. Despite the efficacy and value of the powder, the flavor profile is limited, and we could say more about the texture of the finished product once it is mixed.
