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.
