GI Sustain


Gastrointestinal Nutritional Support

GI Sustain is a medical food formulated to provide specialized nutritional support, including amino acids and prebiotic fibre, combined with readily digestible, low-allergenic-potential macronutrients for '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 (more bad bacteria than good/beneficial bacteria in the intestines) associated with 'leaky gut' syndrome.
