Our Liquid Synbiotic

What is Caya?

Caya is a live and active liquid synbiotic that contains live probiotics, naturally occurring prebiotics and amplified postbiotic metabolites. Unlike pills and powders that need to be awoken in your stomach and intestines, Caya begins to work as soon as it touches your mouth. By targeting the oral microbiome in addition to your gut biome, Caya considers your entire metabolic health—oral health, immune health, gut health, and even brain health.

Caya is unlike anything out there.

No single solution in the market addresses the whole biome.
