Origin of BioGaia’s Reuteri®: The commercial strain of Reuteri® (a lactic acid bacterium) for human use known as Lactobacillus reuteri Protectis or ATCC 55730 was isolated from the breast milk of a woman living in the Peruvian Andes—someone living in perfect harmony with nature. The fact that Reuteri occurs naturally in humans makes it truly a human probiotic.* It is one of very few species of lactobacilli that is uniquely adapted to reside in the gastrointestinal (GI) tract of man.* Most species have their natural living environment outside the human body and are therefore just temporary residents derived from food.*
