Since starting these tablets my health has really improved. I was always feeling tired and tried a range of vitamins that never changed anything. I asked in my local health shop and explained how I was feeling. And was offered optibac it took 3 week's to get into my system, I'm starting into my 4 month and my whole body function is better than it ever was. Getting a full night's sleep and feel so much energy that I can get on with life. As a diabetic I suffered to keep my suger levels under control. But with always being tired I couldn't get out much. That drive my suger up and having bowl syndrome made me feel worse. These tablets has taken over and my lifestyle has improved. These really work and it's best to take one first thing in the morning. And you will start noticing a difference on week 3.
