BCAAs or EAAs? What's the difference?
BCAAs (Branch Chain Amino Acids) are actually EAAs (Essential Amino Acids). BCCAs include Leucine, Isoleucine and Valine and are just 3 of the 9 EAAs.
A high-quality EAA will have at least 5 grams of BCAAs in a 2-1-1 leucine to isoleucine to valine ratio. Taking this during your workout will ensure blood amino acids remain elevated and enable you to continue to perform as strong at the end of your workout as you were at the start.
Each of the 6 other EAAs contribute synergistically to muscle protein synthesis and muscularity. This is especially apparent when EAAs are used under caloric restriction or intermittent fasting.
Interestingly, research has shown subjects going under strenuous exercise who are given BCAAs before training report significantly lower rating of perceived exertion and mental fatigue than those given a placebo.
As well, BCAA supplementation can augment brain function. Those who regular ingest BCAAs before exercise find that mood and mental function is enhanced.
Research has shown that BCAAs support proper immune system function. Finally, it has been shown that BCAA restriction results in increased susceptibility to pathogens leading to increased infection rate.
Taking BCAA's immediately before or during a strenuous workout or cardio session will increase performance. Taking them after with a post work out meal or recovery drink will help speed the replacement of BCAA's in the muscles, increasing muscle recovery and preventing overtraining.
BCAA's and EAA's are great for anyone looking to increase muscle growth and recovery, or anyone looking for a non-caffeine boost. BCAA's and EAA's are a staple in our supplement stack. Haven't tried one yet? Check out our options in our BCAA section!
Thinking of trying out an EAA or BCAA but are not sure which one to use? One of our favourites at Superior Supps is the Axe & Sledge Supplements The Grind. With 5 grams of BCAAs and 2.5 grams of EAAs it will cover all your amino needs. This formula also ha electrolytes and coconut water for hydration!
