Key Takeaways

  • Address metabolic health first – Fix insulin resistance and inflammation before targeting brain-specific interventions.
  • Prioritize sleep quality – Aim for 7-9 hours of deep, uninterrupted sleep to support glymphatic system clearance.
  • Incorporate dual-task exercises – Combine physical movement with cognitive challenges (e.g. counting backwards while walking).

Supplements & Protocols Mentioned

  • Omega-3s (EPA/DHA) – 2-4g daily for reducing neuroinflammation.
  • Lion’s Mane Mushroom – 500-1000mg daily to support nerve growth factor.
  • Time-restricted eating – 12-16 hour fasting windows to enhance autophagy.

Bottom Line

Start with foundational metabolic fixes (diet, sleep, exercise), then layer on targeted nootropics and cognitive challenges. Consistency matters more than perfect protocols.
