Acidophilus was recommended to me by a GP as I took antibiotics for 10 months. It worked well, apparently you would have to eat gallons of yoghurt to get the same effect as 1 acidophilus.
I tried Yakult after a course of antibiotics and they gave me even worse diarrhoea than the antibiotics had done. I learned afterwards that this is quite a common effect.
I have been on antibiotics for a long time and eventually come off them today, hurray. I feel jucky as I am taking all my usual tablets plus some pain killers after a tooth extraction and generally need to take something to get my body back on track. Can anyone recommend a probiotic which may do the trick ?
