Bifidobacterium and Lactobacillus are bacteria found in the human gastrointestinal tract. Supplementation with these bacteria restores normal microbial balance and reduces pathogenic bacteria. Saccharomyces cerevisiae is a non-pathogenic yeast strain used for the treatment and prevention of diarrhoea. Prebiotic fibre are polysaccharides that support the growth of bacteria and gastrointestinal health. Digestive enzymes support healthy digestion and breakdown of toxins to support gastrointestinal health. When ingested on a regular basis, probiotics should improve or normalise the microbial balance in human intestines and thereby improve the functioning of the digestive tract.
