Although individual probiotic species are still available as supplements, the trend is moving toward probiotic formulas that include multiple bacteria species or multiple strains of the same species. Meanwhile, research increasingly focuses on less-known strains of probiotics, which are obtained from human subjects and tested and could be patented. Even if a probiotics label doesn’t suggest refrigeration, it is still recommended to slow natural bacteria die-off.
