Evidence is accumulated that the physiological benefits of probiotics bifidobacteria are not only strain-specific but also dependent on their residential origins. New research by Morinaga Milk reveal that Human-Residential Bifidobacteria (HRB) have superior physiological traits which non-HRB do not have. Among HRB strains, BB536, M-16V, and M-63 possess prevalent beneficial effects in promoting human health, particularly in infants, for which their effects are more remarkable when combined as Triple Bifidus. Given these facts, Morinaga HRB probiotics are ideal for human consumption.
