Cellucor COR-Performance BCAA Review – Worth The Money?

Cellucor’s COR-Performance BCAA supplement delivers the three essential amino acids: leucine, valine, and isoleucine. Why do you need more of these amino acids? According to the Cellucor website, BCAAs taken before, during, and after your workout can increase your rate of protein synthesis. BCAAs can also help you recover faster and support your immune system. That all sounds great, but later in this review, we’ll take a critical look at the research to see if science backs these claims. Other ingredients included in this BCAA supplement are beta-alanine, citrulline malate, and alpha hydroxyisocaproic acid. At the time of writing, a container with 30 servings costs US $39.47 on Amazon.com. Bodybuilding.com lists 234 brands of BCAA supplements with prices ranging from $5 to $75. Cellucor COR-Performance costs a little more than average compared to its competitors. Each scoop of Cellucor COR-Performance contains a 2:1:1 ratio of leucine to valine to isoleucine. Research supports leucine as the powerhouse amino acid responsible for most of the benefits BCAAs can offer you (1). One scoop of Cellucor COR-Performance provides:
  • 2.5g of leucine
  • 1.25g of isoleucine
  • 1.25g of valine
In this post, we’ll look at:

What Are BCAAs And What Can They Do?

BCAAs seem to be one of those supplements that people either swear by or hate. There’s some research supporting BCAAs for preserving muscle mass while cutting weight, but they likely won’t help you gain muscle if you’re already trained. A product like Cellucor’s COR-Performance BCAA supplement isn’t going to turn you into Ronnie Coleman, but it may have subtle benefits for you. Research supports that a product like COR-Performance may do the following:
  • Help novice lifters gain muscle faster (2)
  • Increase aerobic endurance in untrained or lightly trained individuals (3, 4, 5).
  • Reduce fatigue post workout when taken in dosages around 10g (6, 7)
  • Increase fat oxidation during prolonged exercise (8, 9)
  • Reduce muscle soreness post-workout (10)
  • Help you preserve muscle when in a calorie deficit (11)
BCAAs occur naturally in high-protein foods. For example, a scoop of high-quality whey contains roughly 14% leucine and 26% BCAAs (12). A 30g scoop of whey provides roughly 4.2g of Leucine and 7.8g of total BCAAs.

Ingredients In Cellucor BCAA

Let’s examine each ingredient to see how Cellucor’s BCAA supplement can help your body.


Leucine is the most widely studied of the three BCAA amino acids. Research on leucine shows that it may benefit you if you’re trying to maintain muscle mass while cutting weight (2). Most published research examines all three amino acids together, but one study found that a BCAA blend containing 76% leucine preserved muscle during a caloric defect (13).

Isoleucine and Valine

These two amino acids won’t do much for you without leucine. That being said, they seem to strengthen leucine’s effects on your body. One study found that a blend of all three BCAAs increased protein synthesis more than leucine by itself (14).


Beta-alanine, along with creatine, is one of the most studied supplements. Its benefits are similar to the benefits of BCAAs: reducing fatigue and increasing muscular endurance (15).

Citrulline Malate

Citrulline malate seems to have complementary effects to BCAAs. One study found that it may reduce muscle soreness (16). It may also reduce workout induced fatigue (17).

Alpha Hydroxyisocaproic Acid

Alpha Hydroxyisocaproic Acid, otherwise known as leucic acid, is a product of leucine metabolism. One study shows that it increased muscle mass in soccer players over four weeks (18).

Cellucor COR-Performance BCAA Reviews

Cellucor COR-Performance has over 200 reviews on Amazon.com. Most of the reviews are positive, with an average rating of 4.2/5 stars. Most of the one and two-star reviews are because customers found the taste overwhelming. JPM and Chuck recommend staying away from the lemon-lime and watermelon flavors. On the flipside, some customers say that they love the taste. It’s possible that customers who are used to drinking highly sweetened drinks don’t find the taste overwhelming. However, for people who drink mostly water, the taste becomes overbearing. Thomas mentioned that COR-Performance is great as a late-night pre-workout if you’re avoiding caffeine. He rated Cellucor four-stars because there are cheaper options on the market. Some people are complaining that it give them an upset stomach too:

Cellucor COR-Performance BCAA Bottom Line

Overall, you can expect most of the same benefits from taking Cellucor COR-Performance that you’ll notice with other BCAA products. If you’re looking for a caffeine-free pre-workout or a whey powder alternative, this product may be worth a try. The dosage of each BCAA amino acid in this product are in line with the amounts used in research that show it may reduce post-workout fatigue. Cellucor’s BCAA mix also includes several other ingredients that have complementary effects to BCAAs You’re probably not going to notice a huge difference in your workout. However, this product may help you when you’re cutting or if you are trying to keep your insulin levels low. It’s priced a little higher than average, but most people who have left reviews on Amazon seem to like it. The biggest complaint on Amazon was that some customers found the taste too strong.
