Sustamine is a revolutionary dipeptide that combines pure L-Glutamine and L-Alanine to create an ingredient that is more effective than Glutamine alone for rehydration and recovery.*
Sustamine enhances electrolyte and water absorption in the intestines.* It also stimulates glycogen synthesis, inhibits muscle protein breakdown and promotes the synthesis of muscle protein.* Sustamine has also been shown to help protect the integrity of the gastrointestinal tract, contributing to better nutrition absorption.*
A dipeptide is a bonded chain of two amino acids, in this case. L-Glutamine and L-Alanine. Much smaller than a complete protein, a dipeptide can be transported directly into intestinal cells. The muscles get nutrients faster because dipeptides are more efficiently absorbed.
Research shows that a combination of L-Alanine with L-Glutamine is more effective than Glutamine alone for increasing electrolyte and water absorption lost during exercise. L-Glutamine is also the most important amino acid for stimulating muscle protein synthesis, while L-Alanine is an amino acid needed for rebuilding glycogen stores in the body. 1
