Many probiotic supplements contain 1 to 10 billion CFU per dose, but some products contain up to 50 billion CFU or more. However, higher CFU counts do not necessarily improve the product’s health effects. So in this case we can say, more is not necessarily better. This is also stated by the National Institute of Health (NIH). Harvard University has even stated that a dose higher than the recommended range from 1 billion to 10 billion CFUs might even cause health issues.
The 2 cultures we use in Pyour Active, namely Lactobacillum rhamnosus GG (2 billion CFU) and Bifidobacterium lactis BL-04 (1 billion CFU), are very well researched probiotic cultures and are among the best researched cultures on improving the immune system.
