About Sustamine:
  • Sustamine is a revolutionary dipeptide that combines pure L-Glutamine and L-Alanine.
  • Ultra-pure, clinically tested, Sustamine® is produced through a novel enzymatic process that creates a unique dipeptide which is more easily absorbed than a complex protein.* A dipeptide is a bonded chain of two amino acids.
  • Much smaller than a complete protein, a dipeptide can be transported directly into intestinal cells.*
