Collection: Keystone Probiotics
An elite, multi-tiered structural system. Heavily strained options concentrate vital proteins and medium-chain triglycerides (MCTs), while the specialized clinical series introduces targeted, imported live bacterial cultures to isolate health breakthroughs across the gut-brain, gut-skin, and gut-oromucosal axes.
Specialized Clinical Series (Keystone Yogurt Jars)
Thick, glass-jar strained Greek formulations utilizing isolated probiotic cultures.
L. Reuteri Greek Yogurt (Jar)
The Gut-Brain Axis: Communicates directly with the central nervous system via the vagus nerve to stimulate paraventricular neurons in the hypothalamus, triggering systemic releases of oxytocin (the bonding, trust, and calm hormone). This dampens over-activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis, lowering serum cortisol to manage sensory overload, anxiety, and environmental stress.
The Gut-Oromucosal Axis: Actively populates the oral cavity long before it reaches the lower GI tract. By introducing this strain via a thick, sticky medium like our strained A2 Greek Yogurt, the bacteria adheres to oral tissues. It produces reuterin—a potent antimicrobial compound that selectively inhibits cariogenic pathogens like Streptococcus mutans. Users report complete freedom from new cavities, rapid reductions in gum bleeding, and a visible reversal of chronic gum inflammation. Also optimizes anti-aging parameters by supporting skin thickness, dermal glow, and bone mass protection.
L. Reuteri + B. Infantis Greek Yogurt (Jar)
The Pediatric Neuro-Gut Standard: Specifically engineered for pediatric neuro-behavioral protocols. Combines the vagal-calming and oxytocin-stimulating power of L. reuteri with B. infantis, a strain crucial for sealing structural gut barrier integrity and calming the central nervous system. Because our pure A2 milk base creates zero brain-fogging, opioid-mimicking peptides (BCM-7), it prevents inflammatory food allergens from crossing into a child's bloodstream, directly supporting focus, speech development, language development, and behavioral calm in neurodivergent children (Autism/ADHD).
L. Reuteri + Akkermansia M. Greek Yogurt (Jar)
Advanced Metabolic Shield: Connects brain signaling directly to body fat regulation. While L. reuteri manages neurological neurotransmitter availability to suppress stress-eating triggers, Akkermansia muciniphila restores the vital mucin wall layer of your gut. Tightening these cell junctions prevents systemic endotoxemia, providing advanced defense for reversing insulin resistance, decreasing systemic inflammation, and shifting stubborn weight.
Liquid Subset: Keystone Clinical Probiotic Drinks
Clinical-grade, liquid-fermented counterparts matching the exact therapeutic properties, strain selections, and neuro-metabolic mechanisms of the Keystone Jars, formatted into highly bioavailable 240ml beverage bottles.
Pure L. Reuteri Probiotic Drink (240ml)
Clinical Target: Liquid-fermented neuro-endocrine and oral-mucosal delivery. Perfect for coating the teeth, gums, and tongue surfaces to maximize anti-cavity, anti-bleeding reuterin production while traveling down the vagus nerve pathway to activate oxytocin releases for stress and anxiety regulation.
L. Reuteri + B. Infantis Probiotic Drink (240ml)
Clinical Target: Liquid pediatric neuro-gut rehabilitation. A highly absorbable, pourable multi-strain beverage designed for seamless inclusion into children's daily routines. Actively patches leaky gut linings, subdues childhood allergic immune flares, and optimizes focus and behavioral calm.
L. Reuteri + Akkermansia M. Probiotic Drink (240ml)
Clinical Target: Liquid advanced metabolic and mucin-layer restoration. Provides immediate therapeutic fluid delivery to repair internal gut wall integrity, suppress systematic fat-tissue inflammation markers, and actively combat stubborn insulin resistance.
