What Is Schisandra Berry?

Schisandra (five-flavour berry) is unique in containing all five basic tastes — sour, sweet, bitter, pungent, and salty — a distinction recognised in Traditional Chinese Medicine. Schisandrins (dibenzocyclooctadiene lignans) are the primary actives, with significant hepatoprotective and adaptogenic effects demonstrated in both animal and human research.

How It Works: The Science

Schisandrins induce hepatic phase I and II detoxification enzymes, increasing capacity to neutralise toxins and oxidative by-products. They modulate cortisol secretion via HPA axis feedback, reduce inflammatory cytokine production (TNF-α, IL-6), and support mitochondrial function via antioxidant protection of the electron transport chain.

Dosage Guide

Effective Dose

500–2000mg / day

500–2000mg/day of dried berry or standardised extract. Can be taken as a tincture (2–4ml daily). Allow 4–6 weeks for full adaptogenic effect.

Safety Profile & Side Effects

Well tolerated. May cause heartburn or GI upset in some individuals. Schisandra significantly induces CYP3A4 — interacts with many drugs metabolised by this enzyme (statins, certain antivirals, immunosuppressants). Important drug interaction consideration.

Who it's for

Athletes with heavy training schedules who want liver and stress support. Particularly relevant for those taking medications metabolised by CYP3A4 — check with a doctor first.
