Supports muscle, intestinal and immune function
This amino acid is a primary energy source for your intestinal cells and is widely present in muscle tissue. Supplementation may be beneficial during physiological stress.† Supplementing with L-glutamine may also support a healthy intestinal lining and immune function.†
Glutamine is the most abundant amino acid in your body and helps form other amino acids, glucose, protein, and glutathione. Stored in your muscles, it is the primary metabolic fuel for cells in your small intestine, fibroblasts that make collagen, and cells in your immune system.† Supplementing with glutamine can support cells that make up your gut lining, resulting in less intestinal permeability and better immune function.

Glutamine-rich, prebiotic formula supports GI and immune function
Benefits and Features
Powerful support for your entire GI tract and gut microbiota with a blend of supporting nutrients, prebiotics, and glutamine.
Detail Overview
GastroThera™ provides extensive support for the entire GI tract by addressing energy requirements of the intestinal mucosa, structural composition of intestinal and colonic cells, microorganism balance, and production of protective intestinal mucus secretions.† GastroThera™ augments the actions of MultiThera® multivitamin formulas with the amino acid glutamine, the primary fuel for intestinal cell function, to help meet the high energy demands of the GI tract, liver, and immune system during periods of physiological stress and transport ammonia to the kidneys for excretion.† Acacia and inulin add soluble fibers that are readily fermentable into short-chain fatty acids that support the growth of beneficial bacteria, assist water absorption, and support colonic cell function.† N-Acetyl-D-Glucosamine helps form intestinal mucous secretions that protect intestinal tissues and help food pass through the GI tract.† GastroThera™ can be taken regularly or periodically for nutritive support of GI function and is often used with probiotic supplementation. The powder is neutral in taste and readily soluble in water.
