How SMART STRAINS® works

Specifically designed with the science in mind

  • The Right Strain

    Lactobacillus rhamnosus, LGG® is the most scientifically researched bacterial strain in the world. Clinically proven and specifically recommended by the World Gastroenterology Organisation Guidelines on Probiotics, for those on antibiotics.

  • The Right Time

    Starting on the first day of antibiotic treatment, take daily for the duration of the course and continue for 7 days after treatment has ended or until you finish the pack.

  • The Right Way

    Directions: Swallow each capsule whole with a glass of water. For children, open capsule and mix content into cold food or non-fizzy drinks. Preferably take 2 hours apart from antibiotics.
    Dosage: For children and adults from 4 years of age: 2 capsules per day (ideally morning and evening). Provides the recommended 20 billion live LGG®.
