Mitochondrial-oriented micronutritional interventions show mechanistic plausibility but limited clinical efficacy in ME/CFS and fibromyalgia

This narrative review examines the evidence for micronutrient-based therapies targeting mitochondrial dysfunction in ME/CFS and fibromyalgia. It finds that while mechanistic plausibility is strong for several interventions (e.g., NAD+ precursors, CoQ10, magnesium), disease-specific randomized controlled evidence remains limited. The review calls for future RCTs, with one planned for 2027.

Mechanism Graph

Mitochondrial dysfunction and oxidative/nitrosative stress are implicated in ME/CFS and fibromyalgia
↓
Micronutrients are essential for mitochondrial bioenergetics and antioxidant defense
↓
Supplementation may restore mitochondrial function and reduce oxidative stress
↓
Potential improvement in fatigue and related symptoms

Limitations

  • ⚠Narrative review, not systematic, may have selection bias
  • ⚠Limited disease-specific RCT evidence for most interventions

Frequently Asked Questions

What micronutrients are reviewed for mitochondrial support in ME/CFS and fibromyalgia?▼

The review covers NAD+ precursors, B-complex vitamins, magnesium, coenzyme Q10, alpha-lipoic acid, GlyNAC, L-carnitine, pyrroloquinoline quinone, taurine, and creatine.

Is there strong clinical evidence for these micronutrient interventions?▼

No, the review states that disease-specific randomized controlled evidence remains limited for several interventions, despite mechanistic plausibility.

What is the planned future research?▼

A randomized, double-blind, placebo-controlled trial in fibromyalgia patients with clinically significant fatigue is planned for 2027, subject to ethics approval and registration.

What are the key mechanisms targeted by these micronutrients?▼

They target mitochondrial bioenergetics, antioxidant defense, and immune-metabolic regulation, addressing mitochondrial dysfunction and oxidative stress.
