Diverse Prebiotic Support
Benefits and Features
Ther-Botic® BiotaGen® works synergistically with probiotics to ensure intestinal microbiota balance†
- Good source of fiber
- Promotes normal colon transit times while enhancing the absorption of calcium and magnesium†
- Supports gut mucosal barrier and immune function by regulating intestinal epithelial cell growth and increasing populations of butyrate-producing species†
Detail Overview
Ther-Biotic® BiotaGen® is a distinctive formulation of soluble dietary fiber with prebiotic activities that stimulate the growth of colonic populations of beneficial bacteria and enhance gastrointestinal and systemic immune function.† BiotaGen® combines chicory inulin with the immunomodulating actions of larch arabinogalactan and purified yeast beta-glucan.†
Chicory-derived inulin is an inulin-type fructan best known for its ability to sustain increases in populations of Bifidobacterium, Lactobacillus, and Eubacterium, an important butyrate-producing species indigenous to the bowel.† By escaping digestion and absorption in the small intestine, inulin-type fructans arrive largely intact in the colon where they selectively feed beneficial gut microbiota. In addition, inulin-type fructans promote normal colon transit times, enhance absorption of calcium and magnesium, favorably modulate lipid levels, support gut mucosal barrier and immune function, regulate intestinal epithelial cell growth, and reduce the number of potentially undesirable bacterial species.†
Arabinogalactan, a polysaccharide derived from the Western Larch tree, is a highly soluble dietary fiber that enhances immune function by promoting cytokine production and increasing the number of natural killer cells.† Indigestible by human enzymes, arabinogalactan exerts prebiotic properties including the ability to selectively stimulate Lactobacillus species. Arabinogalactan is metabolized to short-chain fatty acids (acetate, butyrate, and propionate) and reduces ammonia production.†
Beta-glucan, a glucose polysaccharide prebiotic fiber, has broad, beneficial effects on immune function through the enhancement of monocytes and macrophages. Beta-glucan stimulates immune responses to a wide spectrum of fungal, and undesirable microorganisms.†
Ther-Biotic® BiotaGen® is recommended to nutritionally support optimal gastrointestinal function, promote populations of healthful colonic bacteria, and enhance gastrointestinal and systemic immune function.† Ther-Biotic® BiotaGen® works synergistically with probiotics to assure intestinal microbiota balance.†

Supports insulin function and glucose regulation
Benefits and Features
D-chiro-inositol has been studied for its role in supporting healthy insulin and glucose metabolism, maintaining normal lipid profiles, and promoting healthy cardiovascular and ovarian function.†
Detail Overview
This stereoisomer of inositol is a critical second messenger mediating cellular responses to insulin. Embedded in cell membranes, D-chiro-inositol is part of a glycosyl phosphatidylinositol complex that is hydrolyzed into two bioactive molecules upon exposure to insulin. These molecules regulate glucose disposal by activating pathways in which glucose is either converted to glycogen for storage or oxidatively metabolized to produce energy.† Studies show D-chiro-inositol is involved in proper insulin and glucose metabolism and may have a role in maintaining normal lipid profiles, cardiovascular function, and ovarian function.† It may also help regulate inflammatory stress and modulate serotonin activity.† Derived from carob pods, D-Chiro-Inositol is recommended to support normal insulin function and blood sugar metabolism.

Supports gut barrier health
Benefits and Features
- Helps protect your stomach and small intestine lining.
- Promotes digestive comfort.
Detail Overview
Zinc carnosine has been shown in multiple clinical trials to help protect the stomach lining and promote gastrointestinal comfort.† Studies show zinc carnosine promotes healthy mucus secretion, exerts antioxidant properties, and modulates cytokine expression, thus helping protect the stomach and small intestine.† L-glutamine promotes small intestinal cell function and mucosal integrity to further support gastric function and protect tissues.†
Research
This patented, 1:1 chelate of zinc and l-carnosine provides a unique configuration that accounts for this compound's unique functions in the GI tract. Zinc-carnosine has a slow dissociation rate and adheres to the stomach lining, allowing for prolonged protection.1 When zinc and carnosine are separated, they provide synergistic antioxidant protection, support the stomach's mucosal defenses, buffer gastric acid, and maintain healthy cytokine release.2 According to studies, this combination is more effective than either ingredient alone in maintaining the integrity of the gastric lining.3 A Japanese multi-center, double-blind study involving 299 subjects found improvements in objective and subjective parameters of normal gastric health and repair, particularly after 8 weeks of daily supplementation.4 Seven additional clinical trials involving over 550 volunteers yielded similar results. In vitro and in vivo studies show that zinc-carnosine promotes cellular repair in the intestine by promoting healthy cell reproduction and villous function.5 Zinc-carnosine maintained healthy gut barrier function in a double-blind, randomized, crossover trial.6 This zinc-carnosine combination has been extensively researched and used in Japan, and it has an excellent safety profile.
