Seems to help with IBS symptoms

5 stars out of a maximum of 5

Hard to know exactly what's working and what isn't with IBS. However, when I began taking Bio-kult S. boullardi my IBS-D symptoms improved around 90%.

Game Changing!

5 stars out of a maximum of 5

One by one, my family and friends have all started taking these wonder-tablets. After many years of nausea and sickness due to stomach problems, trying all medical tests and treatments, my Mother was cured by these tablets. They have been a game changer for everyone I know.

Game changer!

5 stars out of a maximum of 5

I had been struggling for some months with various problems, reflux, bloating and stomach problems, I had various tests and everything was coming back negative, nothing was helping to relieve the symptoms either. I was talking to a friend who told me about Bio Kult and how it had helped her mum with diverticulitis and went on to explain good gut health. She ran round with a box of bio kult that day and all my symptoms disappeared overnight and I have not had a flare up since. It really did change everything for me, I am no longer in constant discomfort and I am sleeping at night. I would recommend this to anyone, I have also got my partner to take them who has had a recent diagnosis of colitis and they have helped to relieve some symptoms.

Life Changing

5 stars out of a maximum of 5

These little miracle workers saved my mother from years of sickness; the doctors tried everything, nothing worked until a dietician suggested these.She’s a changed woman! I started taking them too and I feel so much healthier. More recently a couple, close friends, asked me what my Mum now takes as they were having gut problems. I gave them each a box of these and they are both cured & will be sticking with these S.Boulardii too! Thank you Bio-Kult!
