Think about your body, and how bacteria cells outnumber human cells by 10 to 1. EEK? This is not science fiction, this is science fact! It is estimated that 100 trillion bacterial cells are living on me, and 100 trillion bacterial cells living on you. We live in harmony and balance until something throws it out of balance, like antibiotic use or even poor diet, leading to other health problems. You can get it back into harmony with the right probiotic strains and good food choices.
