GastroThera™ provides intensive nutritional support for the entire GI tract by addressing four key areas of intestinal function: energy requirements of intestinal mucosa, structural composition of intestinal and colonic cells, microorganism balance, and regulation of protective intestinal mucous secretions. Large amounts of the amino acid glutamine, the primary fuel for intestinal cell function, are included to meet the high energy demands of the GI tract, liver, and immune system during periods of physiological stress. Glutamine also transports potentially toxic ammonia concentrations to the kidneys for excretion. Acacia contributes soluble, non-bulking fiber that is readily fermentable into acetic, butyric, and propionic short chain fatty acids that create a supportive environment for growth of beneficial Lactobacillus bacteria, assist water absorption, and support colonic cell function. Inulin supplies non-digestible oligosacharides to further encourage growth of beneficial microorganisms. N-Acetyl-D-Glucosamine is used as a structural component of intestinal mucous secretions that protect intestinal tissues and help food pass through the GI tract. GastroThera™ capsules can be taken regularly or periodically whenever nutritive support of GI function and associated immune modulation is warranted.
