Lactobacillus / Bifidobacterium multi-strain blends
Live beneficial bacteria that colonize the gut, modulate immune responses via gut-associated lymphoid tissue (GALT), produce short-chain fatty acids, compete with pathogens, and maintain intestinal barrier integrity
Typical longevity dose: 10-50 billion CFU/day

Interaction Warnings
Antibiotics
Antibiotics kill probiotic organisms; take 2+ hours apart and continue probiotics after antibiotic course
Immunosuppressants
In severely immunocompromised patients, live probiotics carry theoretical infection risk
Synergies
Prebiotics (fiber/FOS)
Prebiotic fibers feed probiotic bacteria, enhancing colonization and SCFA production
Vitamin D
Vitamin D supports gut barrier integrity, creating a favorable environment for probiotic colonization
