Studies & Information
What are BCAAs?
The group of Branched Chain Amino Acids L-Leucine, L-Isoleucine & L-Valine are referred to as BCAAs. BCAAs comprise approximately 35% of the amino acids from which muscles are formed. A branch chain amino acid is an amino acid having aliphatic side-chains with a branch (a carbon atom bound to more than two other carbon atoms).
What foods contain BCAAs?
The following are some good foods sources for each individual BCAA:L-Isoleucine
- Red Meat
- Brewers Yeast
- Brown Rice Bran
- Soy Flour
- Cottage Cheese
- Red Meat
Why should someone supplement with a BCAAs?
As mentioned, BCAAs make up 35% of the amino acids that form muscle. If you are an athlete, you need BCAAs!
BCAAs are metabolized for the most part in muscle tissue and are used as an energy source for muscle during exercise. BCAAs have been long studied for protein synthesis, but more recently we have discovered that L-Leucine also serves as a regulator that activates protein synthesis through the mTOR (mammalian target of rapamycin). When you exercise, protein degradation occurs causing muscle damage. Ingesting BCAAs before exercise or after exercise has shown to significantly inhibit tissue damage.
When BCAAs are ingested prior to exercise, lactate generation is inhibited because the corresponding coenzyme A compounds are ultimately metabolized and BCAAs directly enter the tricarboxylic acid cycle without the formation of pyruvic acid. BCAA ingestion prior to exercise has also been reported to provide an increase in energy since it is an energy source and preventing fatigue.
