Probiotic Powder for toddlers through teens is a shelf-stable, family-friendly, multi-species and multi-strain powdered probiotic formula. Probiotics are beneficial bacteria or live microorganisms that work by colonizing the small and large intestines. They inhibit the growth and activity of harmful organisms. Research shows that certain strains of probiotics can be helpful for restoring a healthy gut flora after the use of antibiotics and cases of diarrhoea. Orange Naturals Probiotic Powder is formulated with species naturally found in the human intestinal microflora and frequently documented in the research for their therapeutic action.
