ORAL & UPPER-AIRWAY PROBIOTIC
Seed the
mouth microbiome.
Most probiotics live in the gut. This one colonizes the mouth, throat, and upper airway — with clinically studied Streptococcus salivarius strains that crowd out the pathogens behind bad breath, tooth decay, and periodontal stress.

PROFESSIONAL GRADE · 60 CHEWABLES · S. SALIVARIUS · L. REUTERI · L. PARACASEI

Built for the mouth.
Streptococcus salivarius K12 and M18, plus L. paracasei and L. reuteri, are selected specifically for oral and upper-airway adherence — not gut survival. They colonize where bad breath and decay begin.
Occupy the niche.
Beneficial strains work by crowding out pathogenic ones on the same tissues. Chewing slowly before bed lets the probiotics settle into biofilms during the long window when salivary defenses drop.
Ramp, then maintain.
Practitioners may direct up to three or four chewables daily during active support for 90 days, then one nightly for maintenance. No refrigeration required.

Phases of liver detox: glucuronidation, sulfation, methylation, and taurine conjugation
Phase I and Phase II aren't marketing terms — they're specific biochemical steps your liver runs to clear drugs, hormones, and environmental toxins. Here's what drives glucuronidation, sulfation, methylation, and taurine conjugation, and where the pathway typically gets stuck.
