B2B biotechnology company Verb Biotics has published two peer-reviewed studies in the journal Beneficial Microbes that validate the efficacy and mechanism of action for its Keystone Postbiotic, an oat-derived ingredient designed for targeted microbiome support.
Verb Biotics' first study is a four-week randomized, double-blind, placebo-controlled trial involving 76 healthy adults. It demonstrated that daily supplementation with Keystone selectively enriched 33 beneficial keystone bacterial species, including notable increases in Akkermansia by up to 243-fold and Bifidobacterium by 9.6-fold. The ingredient also reduced 38 taxa associated with gastrointestinal distress. Beyond these microbial shifts, the trial also recorded that 68% of participants reported improvements in emotional well-being, with additional benefits including a healthier morning cortisol profile, a significant reduction in the inflammatory chemokine IL-8, and a favorable shift in the albumin to globulin ratio.
The companion mechanistic study details how two specific probiotic strains ferment oats to produce bioactive metabolites at a low daily dose of just 300 milligrams.

What Makes This Trend Stand Out
- Oat-derived Postbiotics
- Validated oat-fermented ingredients signal new potential for low-dose microbiome products that combine digestive, immune, and emotional wellness benefits.
- Keystone Microbiome Targeting
- Selective enrichment of high-value bacterial species such as Akkermansia and Bifidobacterium creates opportunities for more precise gut health formulations.
- Mood-gut Supplementation
- Clinical links between microbiome modulation, cortisol patterns, inflammation, and emotional well-being point to broader positioning for functional wellness ingredients.
Sectors Adopting This
- Biotechnology
- Peer-reviewed validation of postbiotic mechanisms strengthens the commercial path for science-backed ingredient platforms in health and nutrition markets.
- Functional Foods
- Bioactive oat fermentation can expand product development across snacks, beverages, and supplements with microbiome-focused wellness claims.
- Nutraceuticals
- Low-dose postbiotic ingredients with measurable microbial and systemic effects support differentiated supplement formats for daily gut and immune health.
