Caya is not just adding bacteria—we're supporting your entire ecosystem.

Live Probiotics

Introduce live and active beneficial bacteria into your system.

Natural Prebiotics

Feed and support those bacteria so they can thrive.

Postbiotic Metabolites

Deliver active compounds your body can use immediately.

Why traditional probiotics are not enough.

Many do not survive digestion.

Most do not deliver active metabolites.

Typically focus only on the gut.

A new approach to biome support, designed to go beyond traditional probiotics.
01

Caya is alive and active.

Delivers both beneficial bacteria (natural probiotics) and the compounds they produce (postbiotic metabolites).
02

Liquid format for better delivery.

Easier for your body to absorb and utilize than traditional capsules.
03

Advanced precision fermentation process.

Carefully crafted to create a consistent, high-quality synbiotic system.
04

Designed for daily use.

Simple to integrate into your routine for consistent, lasting support.

What to expect over time.
