What Are Branched Chain Amino Acids and How do BCAAs Work?

Posted at 11:00 • 4 Apr • Modern Sports Nutrition • Branched Chain Amino Acids (BCAAs)


Branched Chain Amino Acids or BCAAs are well-studied and are amongst the most popular sports nutrition dietary supplements today.


Athletes supplement with BCAAs to help build muscle,
improve recovery, increase hydration and decrease exercise induced muscle soreness.

Branched Chain Amino Acid Supplements often also include additional ingredients, like electrolytes and ergogenic aids, to increase the benefits from and to improve the efficacy of the overall formulation.

What are BCAAs?


Branched-chain Amino Acids or BCAAs are small, individual units that become "chained" together and that sometimes have side chains that "branch off". These Amino Units come together to form various chains that eventually create Proteins.

There are Many Amino Acids, but only three are Branched Chain Amino Aids (BCAAs): L-Leucine, L-Valine and L-Isoleucine.

BCAAs are Essential Amino Acids

All BCAAs are Essential Amino Acids or EAAs, but not all EAAs are BCAAs. There are 9 EAAs and 3 of these Amino Acids are BCAAs - Leucine, Valine, and Isoleucine.

Why are BCAAs Essential?

BCAAs are called "Essential" because our bodies cannot produce them, making it essential to consume BCAAs through food or supplements in order to meet our requirements for them.

Because of your body's inability to make BCAAs on its own, you'll have to make sure to consume enough of them to fulfill your individual needs and to achieve your intake goals.

Can I Get Enough BCAAs from my Diet?

BCAAs are found in many common foods, but dietary BCAA intake is inefficient and often times insufficient as well.

Food has to be broken down in the gut and then it makes its way through the liver in a time consuming process that's not terribly helpful when you're trying to Fuel Your Workout Now!

BCAAs, Especially Leucine, are Responsible for Stimulating Muscle Growth

Leucine is by far the most important BCAA Amino for Increasing Muscle.

Leucine is most responsible for activating a complex process called mTOR that increases protein synthesis and; therefore, muscle tissue growth.*[6]

 

BCAA Supplements are Quickly Absorbed and Fast Acting

Direct Supplementation of individual BCAAs through a High Quality, Leucine Rich BCAA Powder allows the Amino Acids to be quickly absorbed by bypassing both the gut and the liver.

Faster absorption and availability of Amino Acids floods the muscles with the BCAAs You Need Exactly When You Need Them!

 

What is the Best BCAA Ratio?

We already know that Leucine is the Star, but supplementing with just Leucine can lead to a BCAA imbalance that doesn't maximize results making it important to supplement with all 3 BCAAs. [4]

If Leucine is the most important BCAA, but you need to supplement with all 3 BCAAs to Maximize Results, don't you want to get more Leucine than anything else?

For the Best BCAA, look for a BCAA Ratio that includes all three BCAAs, but that is high in leucine, like the Legendary 8:1:1 BCAA Ratio Contained in Modern BCAA.
