Five ingredients, graded by evidence strength — here's what each one is and what the research actually shows.
One of the best-evidenced nootropic botanicals available. Multiple randomized trials show improved memory consolidation with consistent use over 8-12 weeks.
A well-studied adaptogen with trials supporting reduced mental fatigue and stress resilience; effects on memory specifically are more modest.
Solid evidence for calm, relaxed alertness, particularly paired with caffeine. Standalone cognitive-enhancement evidence is more modest.
A traditionally used root with modest, inconsistent evidence for reaction time and reduced mental fatigue.
Well-evidenced for muscle recovery and exercise performance; evidence for direct memory or cognitive benefits is considerably thinner.
