A Unique Portfolio of Strains

Alimentary Health possesses a unique and extensive portfolio of human origin probiotic strains.
The activity of our strains is being studied in some of the most exciting areas of microbiome research, including the use of bacteria and their components in key areas such as inflammation, infection and brain-gut interaction.

We are applying this to innovative products and ingredients in disease areas such as:

  • Gastrointestinal Health: AH continues to build and support its position in gut health and further advance our science in IBS and related conditions.

  • Stress & Sleep: with recent advances and interest in the gut-brain axis, supported by our discovery of the 1714-Serenitas® strain, AH is focused on the development of further evidenced based probiotics for the management of stress, stress-related fatigue, cognition and learning.

  • Metabolic health: AH is investigating applications of bacterial strains in metabolic conditions and liver health, including fatty liver disease.

We are also developing unique products targeting key life stages, including

  • Pregnancy & early Life: building on new research about the importance of appropriate microbiome seeding of new born babies and the impact on later life, we are studying interventions with well characterised strains for mum and baby to set a child's future health on the right path.

  • Healthy Aging: knowledge is growing on the role of inflammation in aging and of the gut-brain axis on cognition. AH is researching the impact that selected strains have on these key processes.
