What Are Probiotics and Prebiotics in Kefir?
Kefir produced in Nonthaburi using heritage tibicos grains is more than a mild fermented drink—it is a living reservoir of probiotics and prebiotics that work in precise harmony. Probiotics are live microorganisms that, when ingested, support the gut ecosystem by balancing microbial populations, reducing inflammation, and reinforcing immune function at the cellular level.
Our kefir contains 36 microbial strains, including Lactobacillus kefiri, Bifidobacterium longum, Streptococcus thermophilus, and Saccharomyces kefir—each with a distinct role in digestion and microbial regulation. At a concentration of ~12 billion CFU/ml, the probiotic density is sufficient to influence the gut microbiota. After 24-hour double fermentation, the pH settles at 4.32—a level that helps the strains survive the acidic environment of the stomach.
Prebiotics in Kefir: Fuel for Good Bacteria
Prebiotics are indigestible food ingredients that become nourishment for beneficial bacteria in the colon. Kefir naturally contains prebiotics from residual lactose after fermentation, along with amino acids, B-complex vitamins, and certain fibers generated during milk breakdown. These compounds selectively feed probiotics, enabling Lactobacillus and Bifidobacterium to thrive and function optimally.
Each 280 ml bottle contains only 2.1 g of sugar—remarkably low compared to conventional drinks. During the double fermentation, most of the lactose is consumed by the microbes. The remaining sugar is not fuel for pathogens but a targeted substrate for beneficial bacteria, encouraging their sustained proliferation in the gut.
The Synbiotic Relationship: How Probiotics and Prebiotics Work Together
Probiotics and prebiotics in kefir interact through a synbiotic effect. Probiotics are the active agents colonizing the gut; prebiotics are the structural support that sustains their life and multiplication. This two-way relationship creates an environment where beneficial microbes can establish long-term residence.
Daily consumption of 280 ml of kefir delivering ~12 billion CFU/ml, paired with natural prebiotics, does more than introduce microbes—it cultivates a gut terrain that welcomes them. This synergy may help reduce bloating, constipation, and diarrhea associated with microbial imbalance.
How to Drink for Maximum Benefit
To allow probiotics and prebiotics to work at their full potential, consume kefir when stomach acidity is low—such as before sleep or early morning on an empty stomach. Avoid drinking with hot food or alcoholic beverages, as these can impair live microorganisms.
Consistency matters: one bottle daily gives the microbes regular access to the large intestine, where they begin continuous activity. The pH 4.32 of our kefir helps the resilient strains withstand gastric acid, increasing the chance of safe passage and colonisation.
