There are pros and cons with probiotics, which some doctors recommend, but some do not with people with a compromised immune system, like cancer, AID's, terminal illnesses, and infants, being it only introduces more bacteria to the body, which may not be good, and can cause an fatal lactibuillius Septicemia (sp). My doctor just told me to take them with my antibiotics, which could cause C-Diff, which I already had, so I took a few, but stopped. They say in people with a normal immune systems it may be fine, but check the expiration dates being it's live bacteria, and forget the count it should be above, like billions lol, and refrigerated types are better. There are a few good articles I had, but can go to google search. Dangers of probiotics, compromised immune system and probiotics.
Hope this helps.
