70-80% of the human immune system resides in the gastrointestinal system. Research shows when the bacteria in the gut system is in balance you feel good.

Lactose is the natural sugar found in milk, and is the combination of galactose (prebiotic) and glucose. Around 6% of Australians are lactose intolerant, with others reporting feelings of some discomfort after consuming foods containing lactose. As people age the lactose enzyme we naturally retain within our gastrointestinal system diminishes and we become less tolerant.

To help with the digestion of Aziva Kefir, the lactose is broken down into its subcomponents of galactose and glucose during the fermentation process. The lactic bacteria’s within Aziva’s formulation consume the glucose during fermentation to grow, whilst the galactose remains in solution as a feed source for the probiotics to consume in the gastrointestinal system.






Adhesion of probiotic microorganisms to the intestinal mucosa is considered important for many of the observed probiotics that may impact health. Adhesion is also considered a prerequisite for colonisation, pathogen inhibition, immune interactions and barrier function enhancement. Therefore, adhesion is one important criteria to choosing the most appropriate probiotic microorganisms.

Bifodobacterium has been used worldwide for over 30 years as an ingredient in food with no reported consumer illness or injury. Described in over 300 scientific publications and supported by more than 150 clinical studies in persons ranging from new-born preterm infants to the elderly, with no reported serious adverse event.

Clinical studies

The large number of clinical studies and scientific publications indicate that the Bifidobacterium  probiotic strain – alone or in combination with other of our probiotic strains – may provide beneficial effects regarding the gastrointestinal and immune areas.

Published clinical studies indicate that the Bifidobacterium strain when used in isolation and at various dosage rates:

  • May reduce the risk of an upset stomach
  • May enhance the immune response
  • May reduce respiratory tract infections
  • May support bowel function
  • May reduce crying, fussiness and irritability in infants

Combined, the clinical studies also indicate that the Bifidobacterium and Lactobacillus acidophilus strains:

  • May reduce the duration of stomach upset
  • May support the re-colonization of the intestinal microbiota
