Session Outlines and Learning Objectives

About the session

Probiotics are widely consumed for a diversity of applications. Their effect is either direct on e.g. the immune system, indirect through an impact on the microbiota or a combination of both. Deciphering the mode of action of probiotics therefore is challenging, but recent technologies in looking not only “who is there”, but also “what are they doing there” has helped to lift a tip of the veil. This presentation will cover the latest in probiotics science to help understanding the practical application of probiotic products.

Watch this session to:


  • The definition of probiotics
  • Some modes of action of probiotics
  • The research tools necessary to support the understanding of probiotic activity


  • The complexity of studying the health impact of the microbiota (and therefore of probiotics) due to the many confounding factors
  • Strain specific effects in probiotic activity
  • The availability of different probiotic options for different types of application


  • Discriminate probiotic products from fermented products
  • Understand differences in probiotic application fields (e.g. immune regulation versus immune fortification)
  • Better read labels of probiotic products
