After ruling out other conditions I was diagnosed with IBS about 7 months ago. Over the years as the IBS got worse, it really affected my life to the point that I was not sure whether I could risk going on holiday. 

I kept a food diary, read as much about suggested remedies as possible, and decided that probiotics sounded good as a natural way to restore gut health. Having been helped by Linda in the past I turned to her for advice. Linda rung me back and spent 30 mins on the phone suggesting which probiotics to take. 

The probiotics have made such a difference, I have actually got ‘normal’ days now. There is the odd flare-up, mainly caused by stress or too much of certain fruits, on the whole the result is better than I had hoped for. A big thank you to Linda, I would certainly recommend trying probiotics if you suffer from IBS

No refrigeration necessary.
