AB-Kefir, marketed under the ABKEFIR™ brand, is a patented, symbiotic-fermented probiotic and postbiotic formula developed by SynbioTech for everyday digestive health. It reimagines kefir, one of the world's oldest fermented foods, as a stable, standardized, and clinically studied ingredient for modern gut-health products.

A heritage of longevity

For centuries, kefir has been part of daily life in the Caucasus mountains, a region long associated with remarkable longevity. In 1908, the Nobel laureate Élie Metchnikoff connected the fermented foods of the region to the long, healthy lives of the people who ate them, helping to lay the foundation of modern probiotic science. AB-Kefir carries that heritage forward, capturing the natural symbiosis of kefir and translating it into a functional ingredient for today's supplement brands.

More than a probiotic blend

Most probiotic products blend strains that were grown separately. AB-Kefir is made differently. Its strains are cultured together in a single symbiotic fermentation using SynbioTech's proprietary SYNTEK™ technology, so they interact the way they naturally do in traditional kefir. This does two things at once. It generates a rich pool of postbiotic metabolites, such as organic acids, bioactive peptides, polysaccharides, B-group vitamins, folic acid, and amino acids. It also strengthens the strains themselves, improving their stability and their tolerance to stomach acid and bile.

The formula: five plus two

AB-Kefir combines seven probiotic strains. Five are co-cultured together in the symbiotic fermentation, and two more, Lactobacillus acidophilus and Bifidobacterium longum, are then added to complete the formula. These two give AB-Kefir the "A" and the "B" in its name.

Symbiotic fermentation strains

• Lacticaseibacillus rhamnosus LRH10 (formerly Lactobacillus rhamnosus)
• Lacticaseibacillus paracasei LPC12 (formerly Lactobacillus paracasei)
• Limosilactobacillus fermentum LF26 (formerly Lactobacillus fermentum)
• Lactobacillus helveticus LH43
• Streptococcus thermophilus ST30

Added strains

• Lactobacillus acidophilus LA1063
• Bifidobacterium longum BL986

How AB-Kefir supports gut health

By pairing live probiotics with the postbiotic metabolites created during fermentation, AB-Kefir works on gut balance from more than one angle. In everyday terms, it helps:

1. Relieve common digestive discomfort such as constipation, diarrhea, abdominal pain, and bloating
2. Support appetite and ease nausea and difficulty swallowing
3. Modulate the gut microbiota and maintain a balanced digestive environment
4. Deliver postbiotic value that goes beyond live cells alone

Research and recognition

AB-Kefir is supported by five peer-reviewed publications, including two human clinical studies, and is protected by three patents covering its symbiotic composition and encapsulation. It has also earned international invention awards. See Scientific Evidence.

Formats and use

AB-Kefir is designed for easy formulation across powder, stick-pack sachets, and capsules, at a typical daily dose of around 10 billion CFU. It is suitable for food and dietary supplements for the whole family, from daily digestive maintenance to on-the-go routines.
