Creatine is considered one of the most studied sports performance ingredients in the world. It’s estimated that there are over 200 studies dedicated to creatine. And as it would happen, most of those studies are all pointing towards creatine as an effective performance-enhancing ingredient.
Cellucor is a popular company that sells a variety of supplements as well as other fitness good. Naturally, they also have plenty of products that use creatine as one of the key ingredients. However, one of their more popular items is COR-Performance Creatine, a single-ingredient supplement.
How good is COR-Performance Creatine? Will it work as advertised? Read on to find out!
Who Makes It?
The company behind COR-Performance Creatine is Cellucor. They are by no means a small supplement company. They have a lot of stores all over America and employ a lot of international partners from Australia to the United Kingdom.
While the company does sell a lot of protein powders, fat burners, and other types of gym supplements, they’re known for offering a vast array of pre-workouts including creatine formulas such as COR-Performance Creatine. They are probably most well known for their most popular pre-workout product: C4.
Marketing Claims Made
Creatine is first and foremost known as an ingredient that can boost gym performance, and it does so in many was. COR-Performance Creatine focused on just three essential fitness claims:
- More muscle energy for intense exercise: Creatine touches on the entire process that produces ATP. With more ATP comes higher energy levels. Higher energy levels can give you the kind of gym performance you’ve always dreamed of.
- More lean muscle mass: Creatine affects protein synthesis, so more creatine means faster muscle recovery and muscle gains.
- High solubility: The micronization helps the creatine powder to be easier to stir, dissolve, and digest. This also helps reduce bloating and other digestive problems.
These are the basic benefits of creatine. Without stimulants, it can help you get better at lifts, enhance muscle composition, and just overall make you feel better.
What’s in it?
Now, let’s take a closer look at what’s inside COR-Performance Creatine:
As we mentioned, COR-Performance Creatine is a single-ingredient creatine powder. While many pre-workouts have since transitioned far from being a single-ingredient tub, there are still users who either prefer pure creatine or buy creatine powder because they’re into making their own pre-workouts.
Creatine, on its own, also works very well as a post workout ingredient.
The form we have is creatine monohydrate, also known as the most popular form of creatine. Many of the 200+ studies revolved around this form of creatine and of course, positive results were based on creatine monohydrate as well.
However, COR-Performance Creatine separates itself from other creatine monohydrate products because it makes use of a micronized form.
Why does a micronized form of creatine matter?
Creatine monohydrate particles can be quite large. Large particles tend to clump together easily, and this property makes it difficult to dissolve in water (or other liquids for that matter). Undissolved powders will affect not only the drinking experience but also how efficient the powder gets digested and later absorbed.
Undissolved creatine is just hard and annoying to swallow and is often responsible for the digestive issues creatine fans often experience. This is where creatine micronization comes in. 
The micronization process grinds large creatine particles into smaller ones, making the powder finer in the process. Being a fine powder helps prevent it from lumping, improves its solubility, and overall enhances absorption.
More importantly, micronization lowers the risks of having digestion problems including diarrhea and bloating. 
“There is no reason to believe that short-term oral creatine supplementation for 28 days has any detrimental effect on the gastrointestinal tract if taken in a recommended amount (10 g per day in two equal doses). The risk of diarrhea may be increased, however, following intake of 10 grams of creatine per single serving.”
Other than the benefits of micronization, creatine is also known to benefit users with:
- Produce more energy: Creatine supplementation is correlated to adenosine triphosphate or ATP production. ATP is the key molecule our cells utilize to produce energy for everything we do. In terms of exercise, ATP is broken down to produce energy. To make up for this, the body tries to synthesize more ATP but how fast it does this depends on how much creatine you have stored. So, if you have a surplus of creatine coming in (such as when you ingest it), your body becomes an efficient ATP producer. 
- Muscle mass: Creatine has been shown to protein formation to help create new muscle fibers. It can also raise hormones known to be anabolic (or pro muscle). It also enhances muscle water content which is known to boost muscle size. 
- Speeds up muscle recovery: One of the reasons why creatine is so good at building muscle is how it greatly enhances muscle recovery. Every time we exercise hard, we break down muscle tissue. This causes muscle soreness. To prevent this type of pain and damage, the body undergoes a process of muscle recovery that also strengthens it. Creatine helps this process go about its way faster. 
Supplement Facts Label
One good serving of creatine provides:
- Natural Energy: Natural energy means energy that wasn’t sourced from an artificial stimulant like caffeine anhydrous. Creatine boosts ATP production and this enhances energy everywhere else.
- Recovery: Adding creatine as a pre-workout and post-workout greatly reduces recovery time and enhances muscle growth.
- Performance: Adding energy and muscle growth helps users improve their lifting (or even cardio) performance and even break their PRs.
While creatine works well on its own, many say it works best when combined with other ingredients such as those found in pre-workouts or whey powders.
The primary concern is the digestion problems associated with creatine. The micronization process should help reduce this problem, but it doesn’t guarantee to totally remove it.
We always recommend you speak with your doctor before taking any supplements featured on this site.

Cellucor COR-Performance Creatine vs Optimum Nutrition Micronized Creatine
Both Cellucor COR-Performance Creatine and Optimum Nutrition Micronized Creatine offer the same single ingredient creatine. They also used the same science behind micronization.
The big differences are the price, serving variety, and the company itself.
On price, Optimum Nutrition sort of comes out cheaper because they can offer bigger tubs that show better serving sizes relative to their price.
Optimum Nutrition has 150, 300, 600, 1200, and 2000 gram tubs, with the last one costing only $40 and good for 380 servings.
Optimum Nutrition is also considered one of the best supplement companies and the number of athletes and celebrity endorses it’s had over the last few years has only made it sound more premium. Against Optimum Nutrition, Cellucor just doesn’t have that much clout.
Across all the points mentioned, Optimum Nutrition seems to be the more superior brand. However, if you know people who swear by Cellucor, then it’s the brand you should get.
The general consensus on Amazon and most online review sites score it a 4.3/5.
Those who love it praise it for the muscle pumps they experienced, how it dissolves well in plain water, and how the Unflavored tub goes well with their protein shakes and other sports drinks.
Critics cite how even the Unflavored one has a bad bitter taste. Some felt nauseous after using it for the first time.
Inside the gym, you always want to improve your energy, break your records, and have a good lifting experience. Of course, you also want to look and feel better.
Cellucor COR-Performance Creatine promises to do all of those for you and more. If you follow their protocol and pair it with a good diet and exercise routine, you’ll hit your goals in no time.
