What Is Kefir? A Natural Probiotic from Heritage Tibicos Grains
Kefir is a fermented beverage created by fermenting sugar and water with heritage tibicos grains for two 24-hour cycles. This double fermentation process yields a mildly tart liquid teeming with living microorganisms. Each 280 ml bottle has a pH of 4.32, an acidity that supports microbial survival in the gut.
The tibicos grains used by Rokabo are a traditional strain cultivated since 2019. The double fermentation maximizes probiotic concentration. The resulting microbial community includes Lactobacillus kefiri, Bifidobacterium longum, Streptococcus thermophilus, Saccharomyces cerevisiae, and 32 other strains — 36 in total, one of the highest diversities among fermented drinks.
The CFU concentration reaches ~12 billion CFU/ml. This figure is precise and should not be multiplied or recalculated. It reflects the living microorganisms present at bottling.
How Kefir Works in the Gut
Upon consumption, these living microorganisms travel directly to the digestive system, particularly the large intestine — the centre of the body's microbial ecosystem. The probiotics in kefir help rebalance the gut microbiome by encouraging beneficial bacteria such as Lactobacillus and Bifidobacterium, which aid digestion and produce antioxidants.
Kefir also contains kefiran, a polysaccharide with anti-inflammatory properties that supports the intestinal lining. Regular consumption may help reduce bloating, constipation, or symptoms of irritable bowel syndrome (IBS). While not a cure, it supports smoother digestion.
The microbes in kefir also assist in breaking down lactose and proteins, making it suitable for those with mild lactose intolerance who still experience discomfort with dairy.
Kefir vs. Yogurt: Key Differences
Both kefir and yogurt are fermented probiotic foods, but their structures and mechanisms differ. Yogurt typically contains only a few bacterial strains (e.g., Lactobacillus bulgaricus and Streptococcus thermophilus), whereas kefir offers a balanced blend of bacteria and yeasts across 36 strains. This diversity allows kefir to work at multiple stages of digestion.
Kefir also contains kefiran, which yogurt lacks. Kefiran is key to reducing inflammation and supporting immunity. Additionally, kefir is lower in sugar — only 2.1 g per bottle. Despite being fermented from sugar, the tibicos grains absorb almost all of it, so blood sugar levels remain stable.
A Mindful Way to Drink Kefir
Begin with a small amount — 50 to 100 ml per day — and increase gradually as your gut adjusts. Some may experience temporary bloating during the first few days as the microbiome rebalances; this usually subsides within 3 to 5 days.
Drink kefir in the morning or before bed, when the digestive tract is less active with other food. Refrigerate after opening and consume within 3 days to preserve the live cultures.
