Effectiveness scores 77 due to promising RCTs on B. longum 1714 for stress/anxiety at matching 1e9 CFU dose, but evidence limited to small trials without large meta-analyses confirming serotonin or cognitive claims. Safety is near-perfect (97) as strain is well-tolerated with no serious risks. Quality at 82 reflects good transparency but lack of third-party verification; overall 82 (77*0.6 + 97*0.25 + 82*0.15) merits 'Good' for targeted use but not broad replacement for therapy.

Excellent (83/100) - Effectiveness scores 77 due to promising RCTs on B. longum 1714 for stress/anxiety at matching 1e9 CFU dose, but evidence limited to small trials without large meta-analyses confirming serotonin or cognitive claims. Safety is near-perfect (97) as strain is well-tolerated with no serious risks. Quality at 82 reflects good transparency but lack of third-party verification; overall 82 (77*0.6 + 97*0.25 + 82*0.15) merits 'Good' for targeted use but not broad replacement for therapy. Dr. Amen endorsement adds credibility, yet claims exceed evidence (e.g., mood stabilization). Dosages align with studies, supporting targeted gut-brain benefits over generic probiotics.
