Bifidobacteria were discovered and isolated from the stool sample of a breastfed baby in 1899.1 The Chr. Hansen Bifidobacterium, BB-12® originates from our collection of dairy cultures, and is used in baby formula, dietary supplements and fermented milk products (such as yogurt) worldwide.
The BB-12® strain has been described in over 300 scientific publications, making the BB-12® strain the world’s most documented probiotic bifidobacterium. More than 100 of these publications are from human clinical trials that have investigated the impact of BB-12® across various areas of health, in people ranging from newborn preterm babies to the elderly.
BB-12® is safe for human consumption and has been granted QPS17 (Qualified Presumption of Safety) status in Europe and been the subject of a GRAS (Generally Recognized as Safe) notice to the US Food And Drug Administration.18 It has been tested in human clinical studies at levels use of up to at least 100 billion CFU/day (colony forming units), with no adverse events.
