Oral BCAA (Branched Chain Amino Acids) are king
Key roles of BCAA
There is extensive research documenting the key role(s) of branched-chain amino acids (BCAA’s) on the activity and composition of muscle tissue. Their anti catabolic/anabolic effects are a result of the fact that BCAA’s are precursors to keto acids, glutamine, alpha-ketoglutrate and other key metabolites in cellular energy production. The benefits of BCAA’s, like many other compounds, may vary according to the route of administration. Numerous compounds yield greater biological activity and therefore efficacy if administered intravenously.
Not so with the BCAA’s. Research reveals that oral BCAA’s are in fact superior to injectable BCAA’s in regard to anabolism, immune function and gastrointestinal tract integrity. Moral of the story – for maximum anti catabolic/anabolic and immune function support, ensure adequate branched chain amino acid intake by supplementing with a BCAA supplement or by using whey protein, which is naturally rich in BCAA’s, as your protein powder of choice.
