Emergency PEM Prevention Protocol

WarningPractical Warning

This is a mechanistic speculation (certainty 0.30), not an established clinical protocol. No RCTs validate this approach. The doses below are extrapolated from general metabolic biochemistry, not ME/CFS trials. Discuss with your physician before considering any component.]

Post-exertional malaise (PEM) represents a metabolic crisis in ME/CFS. The emergency PEM prevention protocol aims to intervene during the critical 0–72 hour window after exertion to prevent entry into prolonged crash state.

Core principle: Provide exogenous metabolic substrates that bypass damaged production machinery during the period when endogenous synthesis fails.

1 Emergency PEM Intervention Details

Immediate phase (0–6 hours post-exertion):

  • D-ribose: 15 g immediately, then 5 g every 4–6 hours for 24 hours. Provides ATP backbone when mitochondrial synthesis fails.
  • NAD+ precursors: 1000–2000 mg NR or NMN immediately post-exertion, then 500 mg twice daily for 3–5 days. Replenishes NAD+ depleted by PARP activation during DNA repair.
  • High-dose antioxidants: Vitamin C 1000–2000 mg, ALA 300–600 mg, NAC 600–1200 mg. Reduces oxidative repair burden.

Acute phase (6–72 hours post-exertion):

  • MCT oil: 30 mL daily. Provides ketones that bypass damaged mitochondrial complexes.
  • CoQ10: 300–600 mg ubiquinol. Supports remaining electron transport chain function.
  • Magnesium: 400–600 mg chelated form. Essential for ATP synthesis.

Important warnings:

  • This protocol is speculative and based on mechanistic reasoning, not clinical trials.
  • High-dose supplements may cause gastrointestinal side effects.
  • Discuss with physician before attempting, especially for severe patients.
  • May not prevent PEM in all cases; individual variation in response is expected.
