What are BCAAs?

Branched Chain Amino Acids (BCAAs) are three amino acids, Leucine, Isoleucine, and Valine that have branched chains. Evidence shows that these three amino acids, in combination, have a synergistic way of helping the body make muscle and recover.

When most people eat, they are able to receive sufficient BCAAs levels; however, for the sake of the fasted workout, BCAA should be taken 15-30 minutes prior to work out so that your muscles can be fed. BCAAs help keep your body from feeling fatigued. Most pre-workout mixes contain BCAA.

Many bodybuilders and athletes who work out for extended periods of time (over 1 hour) may take BCAA in middle of their workout so that they can continue to feel energy and anti-fatigue for the latter portion of their workout. I don’t suggest this unless you want to be Brolly mode.

Personally, I like working out fasted so I take BCAA supplementation 20 minutes before my workout.

BCAA is NOT a steroid or a hazardous supplement. BCAA is naturally found in most protein sources that we consume.

Additionally, because all three BCAAs are essential amino acids, our bodies do not naturally make them. This means we need to consume them one way or another (protein source or supplementation). One reason why BCAA is promoted for fasted workouts is because when our muscles are being stressed, our muscle absorb BCAAs very rapidly (more rapidly than most other amino acids).
