I tried them, they didn't seem to be a marked improvement and it is claimed that there are several different types, I lost interest, have a go, you have nothing to lose (except a few quid).
I have been taking them
for months, at the advise of my urologist to help keep UTI at bay. Seems to help, I haven’t had one (UTI) for a while. Apparently a good idea to take them if you are in antibiotics.
Further to my original question, I have just finished my first m onthly probiotics and I felt some positive effects after a week. I am continuing the treatment but paying £10 per month compared with the original price of £30. I get my soluble powders from Bimuno, try to Google it. Hugh.
