It contains the strains L. rhamnosus Rosell-11 & L.acidophilusRosell-52 which are both proven to reach the gut alive, even during a course of antibiotics. Suggested for daily use, each capsule provides 4 billion live microorganisms guaranteed until end of expiry. The strains within OptiBac Live Cultures 'For those on antibiotics' are extremely well-researched alongside antibiotics, and are even safe to take at the same time as antibiotics. Each pack contains 10 capsules. It is important to note that this supplement, unlike many products containing live cultures, does not require refrigeration, due to improvements in freeze drying techniques as well as the strains within the product being naturally robust and able to survive harsher conditions. All OptiBac Live Cultures strains are thoroughly researched and documented, so you can be confident you're getting a high quality supplement, which is proven to reach the gut alive. The OptiBac Live Cultures brand was created in 2004 by three siblings and their father, all with a passion for health & wellbeing. The brand specialises entirely in live cultures and considers this to be their expertise, with a particular emphasis on how different strains (specific types of live cultures) work in different ways. The strains found within OptiBac Live Cultures are of the highest quality, and each strain undergoes rigorous testing - so you can be confident you'll find a high quality supplement for your individual needs.1 Ingredients Stabiliser: potato starch; vegetarian capsule: hydroxypropyl methylcellulose; Live cultures: Rosell-11, Bifidobacterium lactis Lafti B94, Lactobacillus acidophilus/helveticus Rosell-52; anti-caking agent: vegetable magnesium stearate; antioxidant: ascorbic acid.

Review: Impressed - Bought these after a severe infection that saw me admitted and 4 different antibiotics pumped into me several times a day for a week. Needles to say my gut biome was in bad shape. I started taking them once back home and after finishing the antibiotics however the improvement in my stomach/ bowels/ overall wellbeing was noticeable after the first 24hrs and then day on day I had noticeable improvement. I highly recommend these and would use them again. Review: Great product - Great product. Felt better as soon as I started them. Good price .
