GI Sustain is a medical food formulated to provide specialized nutritional support, including amino acids and prebiotic fiber, combined with readily digestible, low-allergenic-potential macronutrients for patients with leaky gut syndrome. Featuring L-glutamine and isomalto-oligosaccharides (IMO), this formula supports intestinal mucosal integrity and promotes the growth of beneficial bacteria to address dysbiosis associated with leaky gut syndrome.

  • Supports microbial balance.
  • Nourishes the cells of the colonic mucosa.
  • Features low-allergy-potential rice protein concentrate supplemented with L-lysine HCl and L-threonine for an improved protein source.
  • Provides rice syrup solids as a natural energy source.
  • Provides a readily absorbed and metabolized lipid source.
  • Provides the prebiotic IMO to selectively nourish beneficial bacteria, including lactobacillus and bifidobacteria.
  • IMO is a gentle fiber that is naturally sweet but has a low-glycemic index.
  • Formulated with nutrients such as zinc gluconate and L-glutamine to nutritionally support gastrointestinal mucosa integrity.
