1-2 billion CFU (spores) daily. The IBS-D and gas/bloating trials used 2 x 10^9 CFU/day of MTCC 5856 (LactoSpore); the GBI-30 6086 (BC30) studies used 1 x 10^9 CFU/day.

Tablet or capsule delivering a named strain — MTCC 5856 (LactoSpore) for IBS, GBI-30 6086 (BC30) for the exercise and amino-acid claims
10-20 billion CFU
With or without food (strain-dependent), Same time daily for consistency
Capsules with multiple strains
Redundant rather than harmful. The advantage is delivery, not a distinct benefit — under 10% of spores germinated in the in vitro gastric model, and the organism is only metabolically active after germination.
Choose one. Pick the spore former when refrigeration is impractical, not because it is inherently more effective.

Based on meta-analyses showing benefits for IBS and digestive symptoms. Effect sizes varied considerably between studies with low to very low certainty of evidence. Initial GI symptoms common when starting but typically resolve within 1-2 weeks.
AI-estimated from published studies. Interpret as directional guidance.
Probiotics has a higher evidence score (9/10 vs 5/10) and wins in 2 of 3 categories.
For improve digestion, Probiotics has a higher relevance score (85 vs 58).
