Yes and its no exaggeration when I say they have changed my life!
I had become really food sensitive, lethargic, feeling down, bloated and had piled on weight. My diet wasn’t awful but too much processed food had just upset the balance I believe – I think its called dysbosis, my doctor told me about it after blood tests etc came back fine. I had to cut out more food than I could actually eat without feeling rubbish, inc bread etc.
Started on Optibac Probiotics about 18 months ago and felt better quite quickly. Lost a stone in weight, suffered from less colds etc and now can pretty much eat what I want without negative effects and feel miles better.
Interestingly my mum started on them too and after 2 years of constant colds/viruses she is feeling lots better and her only winter cold came during a week where she had ran out. Could totally be coincidence but she feels loads better so I’m not questioning it!
