Keystone Postbiotic is a food-first, oat-substrate postbiotic clinically demonstrated to improve microbial diversity. Unlike most postbiotics on the market (heat-killed cells fermented on generic substrates), Keystone is engineered around bioactive output and backed by human clinical data. Here’s what that means, and why it matters.
LP815 is a clinically studied, GABA-producing probiotic shown to increase endogenous GABA levels, improve deep and restorative sleep, and deliver particularly strong benefits for women—supporting sleep, stress resilience, immune health, and overall recovery through the gut–brain axis.
The first correlative study connecting the diversity of the gut microbiome to sleep in humans found that people with a diverse gut microbiome correlates with many sleep benefits.
Dive into the fascinating world of the gut microbiome, exploring its functions, its surprising influence on our overall well-being, and how we can nurture this vital “organ” for optimal health.
