Facts for Health Care Professionals

Clinically-tested, pure & stable

Sustamine® is a highly bio-available combination of L-Glutamine and L-Alanine that is better absorbed than glutamine alone.* L-Glutamine begins to degrade when mixed with liquids, but Sustamine® is a unique dipeptide form that's been designed for maximum stability to support hydration and other recovery functions in the body.*

For improved compliance, you can recommend brands with ultra-pure, clinically tested Sustamine® to your patients with confidence.

A superior form of glutamine

Sustamine® is manufactured through a novel enzymatic process that creates a true dipeptide. 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.

Dipeptides are even more efficient than single amino acids. To get into cells, dipeptides and amino acids must wait for a “transporter.” There are only three specific transporters, so the 20 amino acids and their dipeptide combinations compete for available transporters. Since a single transporter can carry a dipeptide, the dipeptide conveys two amino acids through the cell barrier at once. Through coupling for transport, dipeptides drastically reduce the time and energy needed for cellular recovery.

Why combine glutamine with alanine?

Combined into a single dipeptide, Sustamine® L-Alanyl-L-Glutamine is more bioavailable and suports hydration better than glutamine alone.* 

  • Studies show that Sustamine® increases blood levels of glutamine 224% greater than glutamine alone*
  • Sustamine® is more bioavailable that L-glutamine alone*
  • Sustamine® supports the integrity of the gastrointestinal tract and helps maintain healthy intestine function*
  • Research indicates that combining glutamine with another amino acid to form a substrate is more stable and less subject to degradation at high temperatures than glutamine alone. This prolongs shelf life and increases quality*
