Schisandrin is a bioactive lignan from *Schisandra chinensis* fruit. People take it in standardized capsules or extracts, usually with a meal to improve absorption. It helps maintain normal liver function and supports the body's natural stress response.
Typical use centers on liver detoxification pathways and steady mental and physical performance during occasional stress.
Key cautions: Schisandrin can interact with drugs processed by CYP3A4 and CYP2D6 liver enzymes. Mild sedation is possible, so use care with alcohol or other central nervous system depressants. Pregnant or nursing people should speak with a healthcare provider before use.
