From the day you were born your digestive tract (alimentary track) has been introduced to a steady stream of bacteria – some helpful, some harmful. The key to intestinal health is maintaining the presence of helpful bacteria to suppress mass colonization of harmful bacteria. Studies have long shown correlations between certain gut bacteria and common digestive disorders such as Irritable Bowel Syndrome (IBS), lactose intolerance, antibiotic-associated diarrhea, gas, and bloating. , ,
More recent studies have found that the type of bacteria in the gut also affects hormone production and correlates with the incidence of obesity, depression, the overgrowth of disease-causing bacteria and yeasts such as Candida albicans, Staphylococcus aureus, E. coli, Yersinia enterocolitis, & Clostridium difficile, etc. , , , , , , 
Probiotics have been shown in the studies cited are designed to:
- Aid in restoring probiotic balance in the alimentary tract following antibiotic treatment, surgery or chemotherapy, and thereby reduce inflammation and promote healthy healing.
- Increases ability to assimilate the nutrients from food.
- Enhance immune system response.
- Reduce incidence of hormonal disorders, yeast infections, vaginitis and candidiasis.
- Alleviate digestive disorders, such as constipation, diarrhea, IBS and lactose intolerance.
