While it may be tempting to assume that a larger CFU automatically translates to greater probiotic benefits, this is not necessarily the case for every individual or health indication. For some health conditions, a lower dose may work as well or even better than a higher dose, whereas, for other health conditions, higher amounts (50 billion+ CFU) are necessary to provide a clinical effect. Because not everyone needs very large amounts of probiotic bacteria to help restore intestinal balance, the Nordic Flora line offers a range of CFUs designed to satisfy different microbiome needs.
In short, a daily dose of 10-20 billion CFU is likely sufficient for individuals in relatively good health, whereas larger CFUs may be beneficial for people who’ve experienced a significant alteration to their gut microbiome due to illness, use of antibiotics, or other lifestyle factors.
