I'm so confused and definitely need some help. So ive come acrossed some articles which state that Antibiotics can potentially permanently alter beneficial bacteria after the course is done. Antibiotics -may-be-permanently-altering-our-friendly-gut-microbes">https://www.popsci.com/science/article/2011-09/ Antibiotics -may-be-permanently-altering-our-friendly-gut-microbes this is just one. Now if this is true they tell you to just take a probiotic which in most cases is transient and doesn't really colonize the gut. And also you'd only be supplying ten strains compared to hundreds that got destroyed during treatment. Is this true? I'm asking because I want to take antimicrobial s for parasites but I don't want to permanently kill my good bacteria. So depressed right now..
