Study Shows Taking Sustamine® L-Alanyl-L-Glutamine May Reduce Muscle Protein Breakdown After Resistance Exercise

Sustamine® from Kyowa Hakko taken post exercise might reduce muscle protein breakdown.

“Sustamine® altered, immediately post exercise the phosphorylation state of signaling proteins in a manner that theoretically should reduce muscle protein breakdown"

A University of Texas at Austin study showed taking Sustamine® L-Alanyl-L-Glutamine inhibits signaling proteins that activate protein degradation, which helps to maximize muscle protein build-up after resistance exercise. 1

The study published April 3rd in the Journal Amino Acids, included 89 male Spraque-Dawley rats 2-3 months of age who performed resistance exercise. Immediately post exercise, the rats were given either whey protein (.4g/kg), low-dose Sustamine (.1g/kg), high-dose Sustamine (.5g/kg) or placebo, in random order. Sixteen rats were used as sedentary controls.

The primary findings from the study were that Sustamine® altered, immediately post exercise the phosphorylation state of signaling proteins in a manner that theoretically should reduce muscle protein breakdown, while whey protein accelerated the phosphorylation of proteins in the mTOR-dependent signaling pathway thereby theoretically activating muscle protein synthesis.

Sustamine is a dipeptide of glutamine that provides several substantial benefits such as enhanced recovery, immune system support, and increased metabolic rate. This was one of the first studies to demonstrate its benefit on inhibiting muscle protein breakdown.

About Sustamine® L-Alanyl-L-Glutamine
Sustamine® L-Alanyl-L-Glutamine is a stable dipeptide of L-Alanine and L-Glutamine. Sustamine is more easily absorbed by the body than complex protein molecules. This makes Sustamine a highly effective ingredient for hydration, endurance and recovery.* Vegetarian, allergen-free and the only GRAS L-Alanyl-L-Glutamine, Sustamine is also tasteless, odorless, and stable in liquids.
Sustamine is an ingredient that works on multiple levels to help rehydrate the body and sustain energy levels during exertion. Sustamine combines L-Glutamine (the most important amino acid for stimulating muscle protein synthesis) and L-Alanine (an amino acid needed for rebuilding your body’s glycogen stores). Sustamine enhances performance and recovery in three primary ways. It helps:

  • Replace lost electrolytes and fluids
  • Repair damaged muscle proteins
  • Refill the body’s energy stores
