The Beneficial Bacteria in Kefir: What Are They?
Kefir is a naturally fermented beverage born from the fermentation of water and sugar with tibicos grains — a living biofilm housing a complex microbial community. At Rokabo we use heirloom tibicos grains and ferment twice for 24 hours each cycle to achieve a stable, high‑viability probiotic profile. Every 280 ml bottle contains a dense population of living microorganisms, including key strains such as Lactobacillus, Bifidobacterium, Streptococcus, Saccharomyces, and Kefiranofaciens — each playing a distinct role in rebalancing the large intestine’s microbiome.
The Microbial Diversity of Kefir
What sets kefir apart from conventional probiotic products is its sheer strain diversity. Rokabo’s kefir harbours up to 36 strains, spanning lactic‑acid bacteria, yeasts, and bacteria that produce antimicrobial compounds like kefiran — a polysaccharide that helps inhibit pathogenic microbes. This diversity enables synergistic action: efficient fibre breakdown, production of short‑chain fatty acids (SCFAs), and reinforcement of the intestinal mucosal barrier.
Effects on the Digestive System
Once kefir enters the digestive tract, its abundant live microorganisms — in every 280 ml bottle — help create an environment that favours the growth of beneficial gut bacteria. Notably, Lactobacillus acidophilus and Bifidobacterium longum assist in breaking down difficult‑to‑digest sugars and proteins, and may reduce bloating and constipation in some individuals. The kefir’s pH of 4.32 also offers a degree of protection against pathogens such as E. coli and Salmonella.
Designed for Gut Health
Rokabo’s double‑fermentation process ensures that the microorganisms remain highly viable and genetically diverse, while keeping residual sugar at just 2.1 g per bottle — far lower than typical fermented drinks. This makes it suitable for those watching their sugar intake, while still delivering ~12 billion live CFU per millilitre. Regular consumption may support the absorption of B‑vitamins and vitamin K, and bolster immune function via the gut–brain axis.
