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.

Mechanism

Shilajit is a mineral-rich exudate containing fulvic acid (60-80%), dibenzo-alpha-pyrones (DBPs), and over 85 minerals in ionic form. Fulvic acid acts as an electron shuttle in mitochondrial electron transport, enhancing CoQ10 function and ATP production. DBPs protect CoQ10 from oxidation, extending its functional half-life. Shilajit increases total and free testosterone by stimulating steroidogenesis and reducing SHBG. It also enhances mitochondrial membrane potential, acts as a potent antioxidant (fulvic acid neutralizes free radicals), and improves mineral absorption by forming bioavailable fulvic acid-mineral complexes.

Standard Dosing

250-500mg purified shilajit daily (standardized to >50% fulvic acid)

Timing

Morning with warm water or milk (traditional Ayurvedic method). Can be split AM/PM.

Cycle Duration

Cycle 8-12 weeks on, 2-4 weeks off

Side Effects

  • GI discomfort
  • Dizziness
  • Increased heart rate (rare)
  • Allergic reaction (rare)
  • Metallic taste

Contraindications

  • Hemochromatosis (iron content)
  • Active gout (may increase uric acid)
  • Sickle cell disease
  • Thalassemia
