Executive Performance

Cognition + resilience for high-demand professionals

Why this is good for you

Sustained cognitive output, stress resilience and metabolic durability for leaders running long, high-stakes weeks.

  • Lower chronic cortisol — a primary driver of accelerated biological ageing
  • Preserved hippocampal volume and prefrontal performance into the 60s+
  • Reduced cardiometabolic risk from stress-driven visceral fat

Overview

A 12-week stack engineered for executives: protect prefrontal cortex bandwidth, blunt cortisol spikes, defend sleep architecture under travel load, and keep glucose stable through long days.

Who this is for

  • ·Founders and senior operators logging 50+ hour weeks
  • ·Frequent travellers crossing 3+ time zones monthly
  • ·Anyone whose income is tied to clarity, judgement and stamina

The four pillars

Sleep priority

Fixed wake time, 0.4 lux evening light, 19°C bedroom, no caffeine after 12:00.

Cognitive load management

Two 90-min deep-work blocks, then a hard stop. Walk between meetings.

Adaptogenic stress buffer

Daily ashwagandha + rhodiola cycle; L-theanine with morning caffeine.

Metabolic stability

Protein-forward breakfast, no refined carbs solo, walk 10 min after meals.

Phased timeline

Phase 1 · Weeks 1–4

Foundation

Sleep + light + caffeine discipline

  • Lock wake time
  • Cut alcohol
  • Install blue-light blockers post-sunset
Phase 2 · Weeks 5–8

Load

Add cognitive + adaptogenic stack

  • Introduce Lion's Mane + Rhodiola
  • Begin HRV tracking
  • Two deep-work blocks/day
Phase 3 · Weeks 9–12

Compound

Optimise & retest

  • Reassess HRV, RHR, glucose
  • Adjust dosing
  • Add peptide layer if warranted
