C
Evidence

Schisandra chinensis is a traditional Chinese adaptogenic berry standardized for schisandrin content, used to support stress resilience, mental clarity, and physical endurance. Limited but promising clinical evidence suggests benefits for cognitive performance and stress-related fatigue, though larger human studies are needed.

Evidence notes

Schisandra has centuries of traditional use and preliminary human studies support cognitive and stress-related benefits, but rigorous RCTs in Western populations remain limited. Standardization to 3% schisandrins is evidence-informed but not universally established. Grade reflects moderate preliminary evidence without large-scale RCT validation.

Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
