I had suddenly got diarrhoea, from where I have no clue. So I waited for almost a week, hoping it would clear. Eventually went to the doctor and was immediately put on antibiotics. I even asked for IV delivery since I feel awful when taking them. Well, I got worse, finished the course. It got even worse, so I had already ordered these probiotics so started taking them. Within 24 hours I was 70% improved and within 48 hours everything was normal.
In the past have tried OTC probiotics - did nothing. For me, these were fantastic.
