  • Best taken with a meal, preferably with breakfast.

  • Absolutely amazing! My 2 yr old son has suffered from chronic ear infections since birth. Doctors would constantly throw antibiotics at us to no avail. We seemed to be back at our GP every 3 weeks if we were lucky!

    He has had 2 sets of grommets and his adenoids removed which did not help either. His ears were constantly inflamed and he was in agony.

    I started him on Optibac a few months ago, popping one in his glass of morning milk. To be honest, I didn't hold much hope but felt I had to try something. Anyway, we had our ENT checkup a few weeks ago and although one of his grommets has come out, his ears look perfect. No redness or inflammation. Our next appointment is in 6 months time as his consultant is happy not to replace the grommet with the current condition of his ears.

    Thank you so much Optibac. You have given my little boy a better quality of life. He is now a happy child, meaning he has a very happy Mummy & Daddy.

  • People think I work for Optibac as I’m constantly telling my friends with children how fantastic they are! Not only did it completely clear my daughters eczema up (she’d been given steroid cream, it was that bad) which has never returned since, it has cured many of my friends children’s complaints, including suspected colic and bad tummy’s. I now give my children them every time they’re ill, have vaccinations or just for an extra boost. I’ve also read elsewhere that health begins in the gut, so it’s vital that we keep our tummies as healthy as possible.

  • My 3 month old son had to be given IV and oral antibiotics. The antibiotic associated diarrhoea last several weeks after the antibiotics stopped. His stools were constantly runny and smelled bad.
