Why We Love It
  • Promotes good gut bacteria balance.
  • Enhances friendly bacteria colonization.
  • Natural, allergen-free and vegan.
Main Highlights
  • PROBIO 7 RESTORE: Probio7 Restore is a 30-day programme made up of two phases, and was formulated specifically for those on antibiotics, to reboot and replenish their gut microbiome. These gut health supplements helps to re-establish the good bacteria in your gut, and can be used during and after a course of antibiotics
  • PHASE 1: Phase 1 (the first 15 days) is to be taken during your antibiotics to replenish your gut microbiome with good bacteria. Each capsule in Phase 1 contains 100 billion live bacterial cultures that have been proven to reach the gut alive from 8 well researched strains of friendly bacteria, and a strain of friendly yeast, Saccharomyces boulardii.
  • PHASE 2: Phase 2 (the remaining 15 days) is to be taken after your antibiotics have finished to help return your gut microbiome to its former state. Each capsule in Phase 2 delivers 10 billion friendly bacteria to your gut alive, plus a friendly strain of yeast Saccharomyces boulardii. Phase 2 of these gut health supplements also contain added natural fibre that acts as a food source for your friendly bacteria, helping them to grow and thrive in your gut.
  • SUPPORT YOUR GUT HEALTH: Your gut microbiome is home to trillions of bacteria that play a vital role in digestion, immunity, mood, skin and sleep. Antibiotics can disrupt the balance of our gut microbiome, which may lead to certain digestive symptoms during or after an antibiotic course. Therefore, it is considered vital to protect the balance of your gut microbiome during an antibiotic usage.
  • SUITABLE FOR: Probio 7 Restore is suitable for those aged 12+ years, and for best results, start Probio 7 Restore the same day as your antibiotic course starts and continue for 2 weeks after. Take one capsule with a meal 2-4 hours after you have taken your antibiotic, the capsules can either be swallowed whole or pulled apart and mixed with cold food or drink.
