    Across all 3 studies in the database, Bacopa showed beneficial effects on improved attention span, with 2 studies reporting small effect sizes and 1 reporting a moderate effect. The only study reporting a dose used 160 mg/day, and effects were observed in a clinical population with mild cognitive impairment at a median duration of 60 days. The evidence base is very small, so findings should be considered preliminary.
