Health Benefits of BB536

Prepared from Wong et al., 2019. Journal of Functional Foods

For half a century, BB536 has been the superior Human-Residential Bifidobacteria (HRB) probiotic strain that helps people achieve optimal health from the inside out. Ingestion of BB536 can provide a consistent beneficial effect in improvement of gastrointestinal conditions, maintenance of intestinal microflora balance, regulation of immune response, anti-allergy, and protection against microbial infections. It is evidenced that BB536 acts in concert with the gut microbiota to drive a fine-tuned intestinal and immune balance.

Global Use of BB536

BB536 has gained world recognition. BB536 has been used as a functional food ingredient in various products such as milk-based drink, yogurt, infant formula, and nutritional supplements and has been marketed in over 30 countries for more than 40 years.
