Our Beneficial Bacteria

Caya has six carefully selected and studied bacteria.

We use six bacteria that have been collectively researched in over 3,500 studies and connect to form a powerhouse of support for gut health, oral health, brain health, immune health and beyond.

Streptococcus Thermophilus

Streptococcus Thermophilus adapts exceptionally well to plant-based fermentations and is a strong producer of bioactive EPS.These EPS naturally function as a prebiotic feeding beneficial gut bacteria, improving digestion, and strengthening the intestinal barrier, while also helping to scavenge free radicals, protect cells from damage, and produce anti-inflammatory effects in your system.

Lactobacillus Bulgaricus

Lactobacillus bulgaricus ensures a clean and stable fermentation, helping to aid in digestion, maintain microbial balance, and improving nutrient absorption, especially for lactose intolerant individuals, while also boosting immunity, by producing lactic acid and beneficial compounds that inhibit pathogens and support the gut barrier.

Lactobacillus Plantarum

Lactobacillus Plantarum is a powerful plant-origin probiotic that produces antioxidants, peptides, and biome-active metabolites.It remains highly active in plant-based fermentations and supports gut resilience, digestive comfort, and microbiome diversity.This strain contributes strongly to overall wellness and metabolic balance.

Lactobacillus Casei

Lactobacillus Casei thrives in plant-derived environments and is widely studied for its role in enhancing immune resistance.It produces beneficial postbiotics that help modulate immune function and maintain a healthy biome ecosystem, while also helping to reduce bloating, and discomfort, regulate digestion and some studies showing benefit to the oral biome in the way it fights negative bacteria in the mouth.

Lactobacillus Rhamnosus GG

LGG is one of the most researched probiotic strains globally and supports gut and immune wellness.Clinical research shows LGG can help individuals with atopic dermatitis by improving the gut–skin connection.It also strengthens the body’s natural barrier by supporting tight-junction repair and reducing unwanted gut permeability.In plant-based fermentations, LGG stays highly active, making it a powerful contributor to biome balance and skin health.

Bifidobacterium BB-12

BB-12 is a leading bifidobacterium known for improving gut transit, digestive comfort, and immune support.It contributes to the formation of SCFA precursors, helping butyrate-producing microbes thrive in the colon.In gentle plant-based fermentation, BB-12 remains highly active and delivers reliable digestive and wellness benefits.
