The probiotics that I am promoting has undergone trials with members of the National Candida Society of UK. Preliminary results have been very positive and members who were on the trials were very enthusiastic! Therefore to say that probiotics are not proven is rather an uninformed statement.
Furthermore these probiotics had been used for more than 15 years in Asia and countless have benefited from them. It is statements like yours that cause many to continue to suffer, sad to say.
Besides, not sure if you appreciate or understand what exactly is probiotics! The Ontario (Canada) government is currently funding research into probiotics to encourage the people to use probiotics. Even the United Nations - Health Section is working with scientists and researchers on classifying probiotics - whether a food or supplement or otherwise. They recognise the usefulness of probiotics to the digestive system. All these reports are out there on the Internet...
So I would suggest to Vladamir and with due respect to you to read up widely first before making "sweeping comments"!!
