Adaptogen

Schisandra chinensis Extract (Seed)

Also known as: Schisandra chinensis, Chinese magnolia vine, Five-flavor berry, Wu Wei Zi

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.

Primary uses

  • Stress and anxiety management
  • Mental clarity and focus
  • Physical endurance and athletic recovery
  • Liver support
  • Fatigue reduction

How it works

  • Modulation of stress hormones (cortisol, catecholamines)
  • Antioxidant and hepatoprotective activity via schisandrin lignans
  • Potential dopamine and serotonin system modulation
  • Adaptogenic balancing of HPA axis

Dosage

Typical range
500–2,000 mg daily (standardized extract with 3% schisandrins)
Timing
Morning or split morning/afternoon to avoid evening stimulation
With food
May be taken with or without food; consistent timing recommended
Duration
Adaptogens often benefit from consistent use over 4–12 weeks; effects may build over time
Special populations
Pregnant/nursing women should avoid; caution in patients with seizure disorders or on sedating medications

Forms

  • Capsule· 70/100
  • Powder extract· 70/100
  • Liquid extract· 70/100

Contraindications

  • Seizure disorders (theoretical risk from lignans)
  • Acute illness with high fever

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.
