The gut microbiome is essential to normal health and well-being all over the body. Probiotic-3 is a unique synergistic probiotic formula that contains three bacterial species with specific health-promoting attributes: Enterococcus faecium T-110, Clostridium butyricum TO-A, and Bacillus subtilis TO-A. While these three strains are newer to the North American market, they have been widely used in hospitals and pharmacies throughout Asia since the early 1960’s.

C.butyricum TO-A is a natural resident of the human gastrointestinal tract. It breaks down dietary fibre into short-chain fatty acids (SCFAs); butyrate, propionate and acetate. The benefits of these SCFAs include reduced inflammation, protection against intestinal damage,1 thereby preventing “leaky gut” syndrome, improved insulin resistance and immune support.2 E. faecium T-110 is a natural resident of the human gastrointestinal tract that works with C. butyricum to create a balanced microbiome. It produces lactic acid, which reduces the gastrointestinal pH, thus preventing the growth of harmful bacteria.3 It has also been shown to reduce the severity of acute diarrhea. B. subtilis TO-A is a prebiotic that supports the growth of E. faecium and C. butyricum, to increase their growth by 10 times.

Clinical studies have shown wide-ranging health benefits including allergy reduction,4-6 improved immunity, reduced bloating, constipation and diarrhea, positive effects on cognition, depression, anxiety and even enhanced detoxification. Additionally, Probiotic-3 is the only probiotic product in Canada that contains a strain of bacteria from the Clostridium family, which has been shown to have antagonistic effects against several pathogenic bacteria such as C. difficile, H. pylori, and E. coli.

AOR Advantage

Probiotic-3’s unique symbiotic formula combines three human strains that have been clinically studied in more than 40 human studies. It is stable at room temperature and is highly resistant to bile and gastric acids. Additionally, this formula has 60 years of use in hospitals and pharmacies throughout Asia. Each strain was carefully chosen to ensure synergy and safety with the others.

Treatment of Ulcerative Colitis

Study #1:

A single-arm pilot study was designed to evaluate the effect of Probiotic-3 against symptoms associated with treatment-refractory ulcerative colitis. Twenty patients with mild to moderate colitis took three Probiotic-3 capsules, three times a day, for four weeks. The primary outcome measure was resolution of symptoms. In total, 45% of patients exhibited complete remission, with 10% showing partial remission. Analysis of their colonic microbiota showed that populations of Bifidobacteria increased significantly in most patients. Furthermore, this positive response was associated with a normalization of intestinal populations of other commensal bacteria.

Study #2:

A subsequent randomized, placebo-controlled trial evaluated the use of Probiotic-3 to maintain remission, in ulcerative colitis patients previously treated with the standard of care. Here, 46 patients were randomized to receive three Probiotic-3 tablets twice a day, or placebo, for 12 months. The primary outcome measure was incidence of relapse. There were 50% fewer relapses in the Probiotic-3 group than in the control group.

 Gastrointestinal Infections

 Study #1:

 A randomized, double-blind, placebo-controlled trial was designed to test the ability of Probiotic-3 to reduce symptoms associated with acute infectious diarrhea. The study focused on 304 children between three months and six years of age admitted to a primary care centre with viral or bacterial infections. The primary outcome measure was the duration of diarrhea. The children either received a daily dose of Probiotic-3 for seven days, or a placebo. Duration of diarrhea was 30% shorter in children receiving Probiotic-3, and was associated with a 30% shorter hospital stay. Probiotic-3-supplemented children had elevated stool counts of Bifidobacteria, increased production of the tolerogenic IL-10 cytokine, and decreased production of the inflammatory TNFα cytokine.

Study #2:

The standard of care to resolve Helicobacter pylori infections involves administration of a proton pump inhibitor along with an antibiotic cocktail. However, this failed to clear the infection in about a third of patients. In a clinical study designed to assess the effect of Probiotic-3 supplementation on H. pylori clearance, 182 patients were randomized to standard of care supplemented with daily Probiotic-3, or to standard of care alone, for 14 days. The clearance rate with Probiotic-3 supplementation was 84%, as compared to 63% for standard therapy.

 No studies have directly assessed the extent of intestinal colonization by the bacteria in Probiotic-3; however, it is possible to use various biomarkers to obtain similar information. In a clinical study in which participants received daily Probiotic-three capsules for seven days, stool samples were collected on days two, four, and seven for bacteriological analyses. Bifidobacteria and Lactobacilli counts were significantly elevated by day seven. Production of TNFα by patient peripheral blood mononuclear cells was reduced by day two, and IL-10 production was elevated by day six. This data suggests a two to seven-day timeline to action for Probiotic-3 supplementation.
