Best Protein Powders at GNC (Detailed Review)

We are reviewing three different types of protein powders-

• Whey Protein Powders
• Casein Protein Powders
• Plant-Based Protein Powders

Best GNC Whey Protein Powders

Whey Protein is a high-quality protein powder supplement. It is extracted from the liquid whey during the cheese-making process and then processed into powder form using advanced filtration methods.

After analyzing more than 15 whey protein powders, I found these seven whey protein powders for best use. You can use these supplements if you are looking for quality whey protein at GNC.

1. Optimum Nutrition Gold Standard 100% Whey Protein

Whey Optimum Nutrition is a leading supplement brand for a very long time all around the world. ON gold standard 100% whey is one of the most sold whey isolate protein supplements of all time. It’s number one on amazon and tops almost all supplement sites.

But is it worth buying??

Let’s find out!!!

ON Gold Standard 100% Whey Comes in more than 14 flavors. We will review its Double Rich Chocolate flavors.

ON Whey Gold Standard Ingredients

• Protein Blend(Whey protein isolate, whey protein concentrate, whey peptides)
• Cocoa Powder
• Lecithin
• Natural & Artificial Flavors
• Acesulfame Potassium
• Aminogen
• Lactose

First of all, It’s not a pure whey protein isolate. It’s a blend of whey protein concentrate and whey protein isolate. 

Whey protein isolate has the leanest protein among all these three whey proteins.

Whey protein concentrate has the most carbs, fat, and low protein content.

It also contains soy and lactose, which could be issued for people struggling with lactose intolerance. However, It contains lactase and Aminogen, which can help digest lactose and minimize discomfort due to bloating and gas.  

ON Gold Standard Nutritional Information

One serving(30.4gms) of ON Gold Standard 100% provides

• Calories = 120
• Protein = 24 gms
• Carbohydrates = 3 gms
• Sugar = 1 gm
• Fat = 1 gm

Bioavailability of Protein

= 24/30*100

= 77 % (approx)

One serving provides you with 24 grams of protein. 77 % protein bioavailability in a whey protein blend is quite good.

ON Whey Protein Taste & Mixability 

Optimum Nutrition’s gold standard is probably the only supplements that come in more than 15 flavors. The chocolate flavor alone has ten different versions. So, you have tons of options to choose your favorite flavor, which is a positive for the brand.

The double-rich chocolate flavor tastes great with milk, and it tastes OK with water. ON also offers extreme milk chocolate if you prefer intense chocolate flavors.  

It mixes well with both water and milk. ON has used soy lecithin, an emulsifier, and it improves the mixability of the protein powder supplement.

ON Whey Protein Pros & Cons

If you are looking for a 100% pure whey isolate, you’ll have to look for other options available at GNC. However, If you are OK with a protein blend and don’t have any lactose issues, Gold Standard 100% whey is a pretty good protein powder for you. 

Optimum nutrition is a leading supplement brand for a long time now because of its product line. You’ll rarely find any faulty ON supplement. ON gold standard whey protein is a budget-friendly, tasty, and quality GNC whey protein powder supplement.

2. Ghost 100% Whey Protein

GHOST lifestyle is a renowned name among supplements brands. They have been producing whey protein powder, pre-workouts, and vegan protein powders.

GNC has a vast range of whey protein powder supplements, and GHOST whey protein is one of them. It’s one of the best whey protein powders at GNC. Apart from a few things, Ghost whey protein powder is one of the top whey protein supplements. 

Ghost whey protein comes in seven different flavors, and we are going to review its milk chocolate flavor.

GHOST Whey Protein Ingredients

• Whey Protein Isolate, Concentrate, and Hydrolyzed
• Natural and Artificial Flavors
• Digestive Enzymes
• Cellulose & Xanthan Gum
• Sucralose
• Cocoa Powder

One thing I loved is that ghost does, and not every other supplements brand does this, they fully disclose the ingredients profile and what’s in their whey protein blend.

It’s a mix of three different whey, whey protein isolate, whey concentrate, and whey hydrolyzed. Each protein has its benefits; whey hydrolyzed has zero carbs. 

One serving of ghost whey contains 14.53 grams of whey protein isolate, 13.16 grams of whey concentrate, and 2.98 grams of hydrolyzed protein. All three whey types have their own benefits.

Hydrolyzed protein is the fastest to digest, whey isolate has the maximum number of proteins, and whey concentrate has overall health benefits.

Ghost Whey Protein Nutritional Information

One serving(35grams) of ghost whey protein provides

• Calories = 130
• Protein = 25 gms
• Carbohydrates = 4 gms
• Sugar = 2 gm
• Fat = 1.5 gm

Bioavailability of Protein 

= 25/35*100

= 72% (approx)

72% of protein bioavailability is not as high as the ON gold standard, but still, it has many benefits. Soy-free quality gives it an edge over the Optimum nutrition whey protein supplement.

You will not find any soy, gluten, or any other allergens in the protein powder.

It contains artificial sweetener “Sucralose.” However, It doesn’t have other sweeteners like acesulfame potassium, available in many different protein powder supplements. 

GHOST Whey Taste & Mixability

Ghost lifestyle has used thickeners like cellulose and xanthan gums for better mixability. Some people have issues with lactose and thickeners; to fix this problem, they have also added Digestive enzymes like proteases, bromelain, and lactase to help with digestion.

3. Isopure Low Carb Protein Powder

Isopure is a well-known protein brand in the fitness industry. It is popularly known for its two protein brands Isopure zero carb and Isopure low-carb supplements.

If you are looking for a low Carb GNC whey protein powder, Go with Isopure zero carb, It’s best for people following a low-carb diet/meal plan.

Why I Picked Isopure Low Carb over Isopure Zero Carb?

Isopure Whey Protein Ingredients

• Whey protein isolate
• Cocoa Powder
• Soy Lecithin
• Xanthan Gum
• Natural & Artificial Flavors
• Sucralose
• 20 Different vitamins & Minerals Blend

Most of the whey protein powder brands use a protein blend of whey isolate, concentrate, and whey protein hydrolyzed.

However, Isopure only uses whey isolate protein as the primary source of protein. It helps to keep the low supplement calorie, low fat, and low carbs as well.  

Whey protein isolate is a pure form of high-quality whey protein. You can use it for shakes, smoothies, cakes, cookies, etc. It’s easy to absorb and fast to digest as well.

Twenty-plus vitamins and minerals blend make it a micronutrient-rich protein supplement. Thickeners like soy lecithin and xanthan gum are for mixability. Isopure has used natural and artificial ingredients for different flavors.

Isopure Whey Nutritional Information

One serving(34gms) of Isopure low carb whey provides

• Calories = 110
• Protein = 25 gms
• Carbohydrates = 2 gms
• Fibers= 1gm
• Sugar = 0 gm

Bioavailability of Protein= 25/34*100

The lesser amount of fat in protein powder results in faster absorption of protein. Isopure zero fat; that’s why it is quick to digest. You got 25 grams of protein at just 110 calories, making it one of the best protein powders for fat loss at GNC.

Isopure low carb is one of the best or maybe the only Whey protein powder supplement at GNC that delivers more than 20 micronutrients.

Isopure Low Carb Taste & Mixability

It mixes very well, probably because Isopure has used Soy lecithin and xanthan gum as thickeners.

It doesn’t contain any digestive enzymes, which could be problematic if you have a sensitive stomach. 

Isopure low carb comes in six different flavors; the chocolate flavor and peanut butter flavor taste too sweet with milk. You can use water if you don’t like sweet protein shakes.

Isopure Whey Protein Pros & Cons

If you are looking for a low carb, fast-digesting, tasty, great mixability, and cost-effective GNC protein, Isopure low carb protein powder is the right GNC Protein supplement for you. 

4. GNC Pro Performance 100% Whey Protein

GNC has a wide variety of international, protein powder supplement brands. A multichain store rarely produces its protein supplement.

Brands like optimum nutrition and Isopure are well known to the general public, so people don’t hesitate to buy them. Still, when it comes to generic GNC protein like GNC pro performance, people can doubt before buying them.

That’s why I decided to pick this supplement for you, what are the pros and cons of this supplement?

What are the things that give GNC pro performance an edge over the other gnc protein supplements?

Is it worth purchasing?

Let’s Find out.

GNC Pro Performance Whey Ingredients 

GNC pro whey comes in seven different flavors. We are going to review its chocolate supreme flavor.

• Whey Protein Blend (Concentrate, Isolate)
• Cocoa Powder
• Maltodextrin
• Artificial Sweeteners, Salt
• Thickeners

It’s not a 100% whey protein isolate, GNC pro performance whey is a blend of two different whey proteins; whey isolate and whey concentrate. 

Their primary protein source is whey concentrate which has a higher number of fats and carbs than whey isolate and whey hydrolyzed.

GNC has used INS 415 also known as Xanthan gum as a thickener. Thickener enhances the mixability of protein powder supplements.

Artificial sweeteners like INS 955 (Sucralose) and common salt for different flavors.

GNC Pro Performance Nutritional Profile

One serving(36gms) of GNC pro why provides

• Calories = 134
• Protein = 24 gms
• Carbohydrates = 5.4 gms
• Sugar = 4.3 gm
• Fat = 1.8 gm

Bioavailability of Protein 

= 24/36*100

= 66.67%

One serving of 36 grams provides you with 24 gms of protein.

GNC pro whey has quite many carbs and fat compared to other GNC protein supplements like ON whey gold and Isopure whey.

Fat slows down the absorption of protein and raises the overall calorie intake per serving.

GNC has used whey protein concentrate as the primary source of protein with a higher number of carbs and fat than whey isolate and whey hydrolyzed.

This is why GNC pro performance has higher carbs and fat than other brands like optimum nutrition and Isopure.

A high number of sugar, carbs, and fat can be overwhelming for some people. However, if your diet plan allows, You can adjust these extra calories in your meal/diet plan.

GNC Whey Taste & Mixability

It comes in seven different flavors; they have used artificial sweetener “Sucralose” for different tastes. The good thing is, It has no artificial flavors. 

Mixability is okay. However, It doesn’t mix as well as other protein powders at GNC. GNC has used xanthan gum thickener for better mixability. 

You’ll have to use a blender ball or shaker ball to mix it properly.

GNC Pro Performance Price

Pro performance is the cheapest among all other GNC protein supplements. A pack of 1.87 pounds costs only $20 (approx). That’s 82 cents per serving only.

Eighty-two cents for a serving makes it the cheapest whey protein powder in the US market. If you have budget restrictions, this supplement is a good option for you.

GNC Pro Performance Pros & Cons

If you are okay with some carbs and fat in your protein shake, this GNC protein is a good option for you. Yes, Thickeners and artificial sweeteners are a problem for some people, but if you don’t have any issues, you can add this to your supplement stack. 

Twenty-four grams of protein at just 80 cents is a fantastic deal. You can use the following link for exciting deals and additional discounts.

Although, They have used artificial sugar INS 955, also known as “Sucralose.”

Alani Nu Whey Mixability & Taste 

Alani nu has used a combination of different thickeners. They have used soy lecithin, sunflower lecithin, and a blend of guar gum, gum acacia, and xanthan gum.

Thickness improves the mixability of a protein powder supplement, but it can create digestion issues if you have weak digestion.

To make it digestible, companies use digestive enzymes in protein powders. Alani nu has used a combination of five different digestive enzymes to make it more digestible.

Alani nu is probably the only GNC protein that offers unique and creative flavors. There is one blueberry muffin, fruity cereal, and peanut butter brownie available.
