BCAA: leucine, isoleucine, valine are essential amino acids, this means they cannot be synthesized in the human body, and must be consumes via dietary sources. BCAA metabolic process is different from other amino-acids, while most amino-acids are metabolized in the liver, BCAA are metabolized primarily by muscles.
Metabolizing in muscle tissues allows BCAA to be oxidized (used as an energy source by your body during any kind of exercise.) There is a significant increase in BCAA metabolism during prolonged exercises, just because the body requires more energy, that’s why a lot endurance athletes (long distance runners and bikers, triathlon athletes, etc.) can clearly benefit from using BCAA as a dietary supplement.
BCAA are hugely popular among the lifting and bodybuilding community since it increases muscle retention and decreases catabolism (by way of increasing testosterone level and improving testosterone/cortisol ratio, cortisol being a catabolic hormone, which breaks muscles down).
We opted for just simple BCAA with the most proven leucine, isoleucine, valine ratio as 2:1:1 and we are not in favor of adding much BCAA to protein powders, since when mixed with Whey proteins BCAA will take several hours before it can become available to the body, since it needs to be liberated from Whey protein, because BCAA in whey are peptide bound to other amino-acids.
Alone BCAA is free and requires no digestion and absorbed in bloodstream very rapidly and reason for this it’s unique way of metabolism of BCAA by muscles rather than liver or small intestine. We do think BCAA are very useful supplementation to a diet of any physically active person.
