Nutritional Support for the Management of Compromised Gut Function

Formulated to nutritionally manage leaky gut syndrome, Metagenics GI Sustain is a medical food that provides specialized nutritional support, including amino acids and prebiotic fibre, combined with readily digestible, low-allergenic-potential macronutrients for patients with compromised gut function and malabsorption. This formula supports intestinal mucosal integrity and promotes the growth of beneficial bacteria to address dysbiosis associated with high intestinal permeability, and features L-glutamine and isomalto-oligosaccharides. Metagenics GI Sustain works by targeting the potential underlying causes with scientifically demonstrated nutrients that may be difficult to obtain through normal dietary means.

Started this 10 days ago and the results have been amazing to say the least. As a sufferer of IBS for 27 years I didn't have much hope that this would make any difference but to my surprise it has drastically improved my issues. The taste is pretty awful however if you disguise it in a healthy breakfast smoothie then it's no problem at all. Definitely recommend this to anyone battling with chronic stomach issues!
