unique delayed release live bacteria supplement,long term use,children and during pregnancyacidophilus extra 4 billion is one of our top-selling formulas, with each easy-to-swallow capsule delivering 4 billion live bacteria. we often recommend our acidophilus capsules to people who want to take a live bacteria product long-term. acidophilus extra 4 billion is also safe for children and can be taken during pregnancy. our acidophilus capsules contain strains of live bacteria originally isolated from humans and widely used in clinical studies: lactobacillus acidophilus and bifidobacterium. these bacteria are far more at home in our digestive system than the live bacteria found in yoghurt. we\'ve encapsulated acidophilus extra 4 billion in unique delay-release capsules to protect the acid-sensitive bacteria from the low ph of the stomach. the sophisticated properties of our acidophilus capsules slow the rate at which they open, ensuring the complete release doesn\'t occur until 56 minutes after consumption. the capsules\' low moisture content further enhances the live bacteria\'s stability, which means it only releases in the small intestine, where conditions are ideal for growing and replicating. we prefer acidophilus capsules because capsules preserve the delicate \'live\' bacteria. on the other hand, acidophilus tablets are compressed into moulds, which create heat and compromise viability. supplementing with acidophilus only works if the bacteria are kept active in a state of \'suspended animation\' in other words, they\'re still viable after swallowing. so we\'ve designed an advanced, high-density, moisture-resistant pot to protect our capsules from moisture and light, which keeps the live bacteria viable in their packaging. that\'s why we can confidently guarantee a 24-month shelf life. to ensure our strict quality standards are always met, we manufacture and package our formula in uk factories working to good manufacturing practice (gmp). still unsure if our acidophilus extra 4 billion is the right choice for you? then, please have a chat with one of our expert |nutrition advisors//aadvice//class=f-brand !important|. just click the \'nutrition advice\' button located at the bottom right-hand corner of our website to start a live chat with a member of our nutrition team.discover more about eating for a healthy gut |here//b478//class=f-brand !important|.
