Ashwagandha KSM-66 Extract

Ashwagandha may reduce cortisol, which can impair memory consolidation when chronically elevated. Clinical studies using KSM-66 extract at doses around 300mg twice daily have found improvements in memory, executive function, and information processing speed over several weeks, with effects strongest in people reporting high stress. It does not appear to boost cognition in people who are already calm and unstressed.
