Mechanisms of Action
Functional redundancy from Keystone Postbiotics’ intentionally selected ingredients delivers three synergistic mechanisms of action in the GI tract that together help support and strengthen foundational gut microbiome health.

Combining strains and grains for functional redundancy
Keystone Postbiotic® is produced through the precision fermentation of oats using two carefully selected probiotic strains—Lactiplantibacillus and Lacticaseibacillus—chosen for their ability to work together and create health-supporting compounds. This process helps deliver targeted benefits for gut health and microbiome balance.

How Keystone Postbiotic® works
Keystone bacteria
Keystone bacteria, such as Bifidobacteria, are important players in overall gut microbiome health. Bioactives found in Keystone Postbiotic™ increase keystone bacteria in the GI tract.
Metabolite driven
Keystone bacteria enhance the production of beneficial metabolites, such as butyrate, that have been shown to promote intestinal epithelial health and help balance digestive microflora.
Intestinal barrier integrity
Intestinal barrier integrity is paramount to a healthy gut and pivotal for a healthy immune response. Keystone Postbiotic tightens the intestinal barrier by promoting short chain fatty acid production, regulating tight junction proteins, and supporting the growth of keystone bacteria, such as Bifidobacteria that are correlated with a healthy intestinal barrier.
Immune function
Keystone Postbiotic regulates levels of cytokines that play a crucial role in our immune system education, epithelial health, and inflammation response. By modulating these cytokines, Keystone Postbiotic helps protect barrier maintenance and wound repair in times of stress, while promoting a responsible immune response.
Shelf-stable for a wider range of applications
Stability
Keystone Postbiotic is both shelf and ‘process stable’ and does not need refrigeration.
Applications
Keystone Postbiotic is heat-inactivated, making it highly versatile for use across a wide range of functional foods, beverages, and dietary supplements.
