For long-term use, choose evidence-based, affordable options. Multi-strain probiotics with ≥10 billion CFU plus a prebiotic are adequate. Options like VSL-3 sachet (alternate days) or Econorm Plus / Sporolac DS are reasonable.
Benefits plateau after 2–3 months; higher-priced brands are not necessarily superior.
