What does it take to be an elite in the whey protein powder industry? With so many claiming to be the best, you could get lost with all the scientific jargon and promises of better gains and fast absorption.
COR-Performance whey protein powder wants to be part of some of the truly elite in this industry. However, it’s a silent underdog compared to some of the powders we’ve seen.
Do note that COR-Performance is sold by Cellucor, a reputable company that’s built a name for itself for the last two decades.
How will COR-Performance fare against our intensive review? Will it work as advertised? Read on to find out!
Who Makes It?
Cellucor is the big brand name that’s behind COR-Performance . They sell pre-workouts, fat burners, post workouts, testosterone boosters, protein powders, and even apparel and some gym accessories.
Marketing Claims Made
COR-Performance Whey Isolate Protein is described as an optimal source of protein when you’re looking to maintain lean muscle, replenish nutrients after a workout, and indulge your sweet tooth guilt-free.
The company further states that for every two scoops of COR-Performance Whey Isolate Protein Powder, you get a whopping 24g of fast-acting whey protein and digestive enzymes.
This serving of potent ingredients can help satisfy your protein needs any time of the day.
The following claims were made about Cellucor COR-Performance:
- Fast-acting protein: Having a fast-acting protein is not clear cut for COR-Performance. That’s because it makes use of two different types of whey protein: Whey protein isolate and whey protein concentrate. Between the two, whey protein isolate is the one absorbed the fastest. Whey protein concentrate isn’t considered a fast protein, but it is a fast ingredient compared to other protein sources.
- Digestive enzymes: The presence of protease and lactase tells us the people behind COR-Performance mean it when they say they want to have a fast-acting type of protein. However, enzymes work in ways we sometimes can’t measure. So, it will be up to the person if the protein powder digests and gets absorbed fast or not.
- Minimal fat and carbs: The 3 gram carb serving may be already high for some, especially if they’re following a low-carb or ketogenic diet. However, we do like that it only has 1.5 grams of fat.
What’s in it?
Now, let’s take a closer look at what’s inside COR-Performance:
- Whey Protein Isolate: When it comes to whey protein, whey protein isolate comes out as the more expensive and more sought after compared to whey protein concentrate. This is because whey protein isolate is 90% protein per gram compared to whey protein concentrate that is only 70%. The difference is due to the “impurities” in whey protein concentrate. Unlike whey protein concentrate, whey protein isolate has a reduced cholesterol content, carb, and basically devoid of lactose. This makes whey protein isolate a better whey protein form for those who have trouble with dairy products. And because whey protein isolate is much more pure, it’s also much more efficiently absorbed by the body.
- Whey Protein Concentrate: Whey protein concentrate is the basic form of whey protein. In fact, many users consider whey protein concentrate as raw whey protein. It’s the form right after skim milk is processed for its whey protein content, so it still has high cholesterol, carbs, and of course lactose. Whey protein concentrate is easily manufactured, cheap, and perhaps the most abundant form of whey out in the market today. The problem is, it’s also only available at 70% purity. Not to mention it’s not ideal for those who are sensitive to dairy or prone to digestive problems. However, many say whey protein concentrate tastes better than its expensive counterpart, whey protein isolate.
- Protease, Lactase: These are what you call digestive enzymes. Enzymes in general help the gut absorb nutrients faster. Digestive enzymes added to supplements are not new, but many say they’re supposed to be staples in protein powders. This is because protein powders are generally harder to digest than other types of supplements. Enzymes help the system work faster in absorbing the proteins as well as breaking them down into their amino acid building blocks. On top of proteins, digestive enzymes could also help with undigested foods in our stomach which is beneficial for those who have general issues with digestion.
Supplement Facts Label
Since the nature of COR-Performance is of a protein powder, we can narrow the benefit down to just three things:
- Bulk: Protein powders are bought to help the body grow bigger muscles. The science is solid for this one benefit. The more protein you have stored while training, the better muscle growth you’ll have.
- Recovery: Muscle recovery and growth go hand in hand. The more amino acids your body has, the faster recovery will be. Faster recovery leads to bigger gains.
- Performance: While proteins are better known for their bulking properties, they can also have a good effect on overall performance. Whey protein powders are much easier to digest than meat or eggs, making them efficient sources of energy and explosiveness.
Added to those benefits is the presence of digestive enzymes which allow for easier gut digestion and protein breakdown.
Here’s the kicker: COR-Performance could set you up for a good bout of bloating. It’s not the fault of the company as much as it is the very nature of protein powders.
Generally speaking, protein powders take time to digest and when they come into contact with stomach acids, they produce gases.
The gases may or may not build up in your belly or you may have trouble with indigestion if you’re particularly prone to them.
Then, there’s also the issue of having quite a high amount of sodium. At 8% per serving, it’s certainly among the highest we’ve seen. We’re not saying 8% is enough to trigger problems, but we already take a good amount of salt through regular food already. Adding that may just have a compounded effect, especially if we take the supplement every day.
We always recommend you speak with your doctor before taking any supplements featured on this site.
How to Take It
Cellucor recommends taking COR-Performance with two scoops added to 6 to 12-ounce cold water or any beverage of choice. They also recommend up to twice daily, but that can easily deplete your can.
Currently, COR-Performance has seven flavors:
- Molten Chocolate
- Whipped Vanilla
- Cinnamon Swirl
- Peanut Butter Marshmallow
- Cookies N’ Cream
- Chocolate Chip Cookie Dough
- Strawberry Milkshake
Number of Servings
One can of COR-Performance contains 28 servings. Ideally, this 28-serving can will last 28 days, but if you follow the twice-daily recommendations, then you might end up with just two weeks worth of protein powder. This also makes COR-Performance cost twice as much.
Top Alternative to This Product
Cellucor COR-Performance Whey vs MusclePharm Combat Powder
Based on protein content and formulation, the best alternative to COR-Performance Whey is MusclePharm Combat Powder.
Like COR-Performance Whey, MusclePharm Combat Powder made use of a combination of protein powders to produce what they deem is ideal for muscle growth and recovery.
The difference is, where COR-Performance Whey used two (whey protein isolate and whey protein concentrate), MusclePharm Combat Powder used five different protein sources under their Microfiltered Protein Blend:
- Whey Protein Concentrate
- Whey Protein Isolate
- Egg Protein
- Whey Protein Hydrolysate
- Micellar Casein
We already know what whey protein concentrate and whey protein isolate are, so let’s focus on egg protein, whey protein hydrolysate, and micellar casein.
Egg protein is pretty easy to understand: It’s simply protein sourced from eggs. Some companies don’t like egg proteins because they’re dairy by default and bring unnecessary allergens. Also, because egg proteins might have more than their fair share of cholesterol especially when processed for purity.
Whey Protein Hydrolysate is like whey protein isolate but filtered and micronized. This is considered the most expensive and fastest absorbed form of whey protein, but also the least used due to its manufacturing costs.
Micellar Casein is one of the slowest digestible proteins out there. To act as a counterbalance to whey protein hydrolysate, MusclePharm Combat Powder was formulated with Micellar Casein for those who like to have an appetite suppressant effect on their beloved protein powders.
Based on the formulations and other ingredients, it seems both COR-Performance Whey and MusclePharm Combat Powder have a lot in common. The dosages aren’t also that far apart, especially since both protein powders provide 25 grams of protein per serving.
It will then all boil down to preference. Some will definitely like COR-Performance Whey for its simple whey protein blend, while others may prefer MusclePharm Combat Powder for its unique approach to protein powder formulations.
The general consensus on Amazon and most online review sites score it a 4/5.
Some of its fans say they like the flavors available, its good mixing consistency, and the lack of a chalky aftertaste. They also seem to like the chocolate flavor compared to the other flavors in its line. Others like its price point.
Then, of course, we have critics who hit it for its possible side effects, difficulty in swallowing, and just not enjoyable in certain mediums such as regular protein shakes.
Cellucor COR-Performance is the kind of protein powder that could be divisive among long-time users.
On one hand, it carries a tried and tested combination of whey protein forms that are known for their ergogenic and muscle growth benefits. It also contains ingredients that help the overall experience, especially when it comes to better digestion.
On the other, it can appear not as efficient compared to single-ingredient protein powders, the number of fillers it has may not bode well with the general consumer, and we also have the problem with the salt content as well as tub size availability.
Regardless, COR-Performance isn’t pricey and doesn’t try to sell itself as the best or that of a premium made. It’s still a decent looking protein powder which should work if taken properly. If you find the formula to your liking, by all means, go for it.
