[Verb Biotics'](https://www.trendhunter.com/trends/probiotic-ingredient) 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](https://www.trendhunter.com/trends/greenvit-aronvit).
