Sustamine® L-Alanyl-L-Glutamine is clinically tested

Sustamine has been shown to enhance electrolyte and water absorption in the intestines, stimulate glycogen synthesis, promote the synthesis of muscle protein and even to help stimulate the immune system.* Sustamine has also been shown to protect the integrity of the gastrointestinal tract, contributing to better nutrient absorption.*
