The probiotic drinks and live yogurts in the shops contain microbes but generally only from one or two families such as lactobacillus and streptococcus. They may also contain sugar and preservatives. Of course, they are better than fizzy drinks or processed food, but it will take a long time and a lot of them to benefit your digestive system. Our probiotic contains a wide range of microbes from 15 main families of bacteria, and within that there are many subcultures so it is a more complex and wide-ranging mix.
