Evidence map: Focus & memory

Explore clinical evidence across memory, attention, mental speed, and executive function.

Across 83 ingredients and 4 outcomes, this map shows 190 studied pairs covering 149 distinct clinical trials.

Where cells are blank, the (ingredient, outcome) pair has not been studied — 142 such gaps remain on this map.

Methodology

Each studied pair shows its V2 verdict, GRADE certainty, contributing-trial total, and source evidence. Where an audited standardized effect is available, the receipt shows the estimate and its confidence interval when available. Generated 2026-10-24 from 149 contributing trials.
