Probiotics (Multi-Strain)
Beneficial bacteria supporting gut microbiome diversity, digestion, and immune function.
Projected serum levels — 10 B CFU (≈ 10 mg), once daily
Maintenance schedule: 10 B CFU (≈ 10 mg) once daily (oral).
Modeled steady state after ~7 days: peak ≈ 0 mg, trough ≈ 0 mg body load. Population-based estimate over 15 days for a reference dose at a 70 kg reference body mass — the interactive app scales curves to your doses, timing, and body mass.
