I'm not taking them now. I just try to maintain what is established. You shouldn't need to take them at all. The modern processed food diet, antibiotics, and other "toxins" cause our biome to die off. Some of the strains are not replaced by our food. There is a laundry list of strains in the high quality pills. Essentially, once you have it, you have it. Unless you fail to nourish it. It takes a while for the digestive track to rebuild itself after biome is restored. It has those cilia-like fingers that operate in a mucus layer, and those die back or recede as does the mucus layer. That takes a while to reestablish.
