EAA’s have grown in popularity over the last several years, and for good reason. Though what’s the difference between EAA’s (essential amino acids) vs. BCAA’s (branch chain amino acids) and how do you know which one is best for you?  

First, the basics. EAA’s, or essential amino acids, contain the nine essential amino acids that cannot be produced by the human body. These include histidine, lysine, methionine, phenylalanine, threonine, tryptophan, leucine, isoleucine, and valine. BCAA’s, or branch chain amino acids, contain a subset of the above, including leucine, isoleucine, and valine. 

So, where do we go from here?  

Understanding EAA’s: 

If your goal is general health and wellness, an EAA supplement can best suit your needs for a few reasons. Taking all nine amino acids helps with protein synthesis, workout recovery and muscle repair, muscle soreness, hormone balance and energy production.  

Those who don’t consume a diet that’s rich in animal protein, especially that from fish, can greatly benefit from adding this supplement to their stack. It’s also gained traction in the endurance world for helping athletes take on long and strenuous activities when whole foods aren’t an option.

In a single 10g serving, you get 5.2g of BCAAs at a 2:1:1 ratio of leucine, isoleucine, and valine; plus, histidine, methionine, phenylalanine, threonine, and tryptophan; as well as electrolytes: sodium, potassium, magnesium, and calcium for proper hydration.  

Understanding BCAA’s: 

It might be easy to rule out the effectiveness of BCAA’s when a supplement that offers all nine essential amino acids exists. Though, there is an added benefit of singling out the main three branch amino acids found in BCAA’s- muscle building.  

Leucine is the largest trigger of protein synthesis, isoleucine plays a crucial role in energy production and post exercise recovery, and valine acts as a muscle preserving amino acid plus helps reduce fatigue during prolonged exercise.  

BCAA’s also have a faster absorption rate than EAA’s. BCAA’s are absorbed in the small intestines, bypassing the liver and moving directly into the bloodstream whereas EAA’s must pass through the liver.
