http://www.usprobiotics.org/ I believe after a year of trying to get my body straight after menopause I've found a wonder pill in probiotics. Many of you may not know that during perimenopause and menopause the PH balance of the vagina may be thrown off causing a woman to be more UTI and yeast infection prone. After 6 straight months of on and off yeast infections, I've finally found a solution through my pharmacy's menopause specialist. My obgyn never mentioned this as a solution!!! Wanted to share with all of you. This stuff also seems to be helping with my occasional IBS, too. It is recommended that anytime antibotics are used, probiotics should be used also to replace the good bacteria. I believe this goes for children as well so discussing with a pediatrician may be beneficial. These are purchased from Health Food stores or Health internet sites.
