Inner Armour Blue Amino Recovery 4:1:1 contains an elite ratio of branched-chain amino acids. While all BCAAs play an important role in muscle growth, it is Leucine that has been shown to critically impact muscle protein synthesis. Leucine has been suggested to increase glucose and amino acid uptake in muscle and is often regarded as the single most powerful muscle synthesizing amino acid.
Glutamine is suggested to have a regulatory role in whole-body protein synthesis as its levels inside the muscle govern protein synthesis and nitrogen balance and therefore muscle building. Research shows that when adequate amounts of Glutamine are ingested, the body increases the rate of protein synthesis, speeds recovery time and increases the rate at which lean body mass is gained.
