Thaena

Thaena is a private Portland, Oregon microbiome-focused health company developing and selling human-derived complex postbiotic products. Its flagship product, ThaenaBiotic, is marketed as the world’s first stool-derived complex postbiotic supplement and is produced from rigorously screened healthy human donor material that is sterilized, refined, and shelf-stabilized. The company positions its approach as restoring missing postbiotic signals to support gut ecosystem recovery, resilience, and broader health outcomes including longevity-related biology. In addition to commercialization of ThaenaBiotic, Thaena appears to be building an IP-backed platform around fecal-derived sterilized postbiotic compositions and related applications in anti-aging and neurotherapeutic settings. The business sits at the intersection of microbiome science, consumer health, and emerging biotech-enabled wellness.
