This gold standard efficacy is made possible by the "quorum sensing" state of microbiota in each product, which can only be obtained in an active, biologically correct fermentation state. get deep: to explore rye kvass science, click on underlined text for scientific works cited Organic, wild fermented kvass is a naturally carbonated "rye soda" containing powerful synbiotics for unmatched gut microbiome support: probiotics: 40+ naturally occurring living species of bacteria (billions of CFUs) and beneficial microorganisms in a quorum sensing state - full of robust, effective communities that integrate into the microbiome prebiotics: soluble & insoluble rye fiber to feed existing & new health gut microbiome bacteria postbiotics: vital microorganism metabolites that promote microbiome, immune system, metabolism and hormonal health not found anywhere except living, correctly fermented foods Volgin's custom created wild rye kvass culture is comprised of native rye microorganisms from freshly germinating organic rye grain berries. This ensures powerful & complete rye fermentation, the same way it would happen spontaneously in nature. Native rye microorganisms make up a vital part of a diverse, healthy human gut microbiome and work symbiotically with other correctly fermented foods. Rye kvass specializes in: high levels of bioavailable B vitamins: wealth of vitamins B12 (19% DV), B3 (19% DV), B2 (15% DV), B1 (14% DV), selenium (7% DV), manganese (7% DV) & microelements for nervous system, brain health & metabolism high bioactivity: bioactive compounds made by active microbiota provide anticarcinogenic, antidiabetic, hypoglycemic, antioxidative properties metabolism boost: high bioactivity and lower carbohydrate load due to high fiber which help offset already low naturally occurring sugars digestion: promotes digestive health & helps stomach function/motility
