CategoryAdaptogensAdaptogens
Standard Dose500-1000mg daily (standardized to >2% schisandrins)

Evidence LevelModerate (preclinical strong, human emerging)moderate_human

Mechanism

Desert plant extract containing echinacoside and acteoside that support testosterone via LH stimulation, enhance neurogenesis via BDNF upregulation, and improve gut microbiome composition. Traditional use as 'desert ginseng' for vitality and cognition.

Contraindications

  • Autoimmune conditions (immunomodulatory)

Mechanism

Schisandra berries contain lignans (schisandrin A, B, C; gomisin A, N) that are the primary bioactives. Schisandrin B is a potent inducer of hepatic Phase I (CYP450) and Phase II (glutathione S-transferase, UDP-glucuronosyltransferase) detoxification enzymes. Schisandra activates Nrf2/ARE pathway, increases glutathione synthesis, and has hepatoprotective effects by stabilizing hepatocyte membranes. It modulates the HPA axis, reduces cortisol, enhances mental performance under stress via cholinergic and catecholaminergic modulation, and improves mitochondrial function through enhanced cytochrome c oxidase activity.

Standard Dosing

500-1000mg daily (standardized to >2% schisandrins)
