The Role of Mitochondria in Energy, Ageing, and Chronic Illness
Feeling tired, sluggish, or ageing faster than you should? It could be down to your mitochondria — tiny structures inside your cells that produce energy. Without healthy mitochondria, your body can’t generate the power it needs for every function, from thinking clearly to maintaining muscle and immune health.
Research in Cell Metabolism and Nature Reviews Molecular Cell Biology confirms that mitochondrial dysfunction plays a role in conditions like fatigue, fibromyalgia, diabetes, cardiovascular disease, and neurodegenerative diseases(Source 1, Source 2).
Why Do Mitochondria Decline?
Chronic stress and high cortisol
Nutrient deficiencies (CoQ10, B vitamins, magnesium)
Toxin exposure (heavy metals, mould)
Poor sleep and lack of movement
Ageing — mitochondria naturally decline with age
Symptoms of Mitochondrial Dysfunction:
✅ Persistent fatigue or exercise intolerance
✅ Brain fog and memory problems
✅ Muscle weakness
✅ Increased sensitivity to stress
✅ Premature ageing
How to Support Mitochondrial Health:
✔ Eat a nutrient-dense diet rich in antioxidants
✔ Support with targeted supplements like CoQ10, magnesium, alpha-lipoic acid
✔ Improve sleep quality
✔ Exercise regularly — even gentle movement stimulates mitochondria
✔ Reduce exposure to toxins and heavy metals
Protecting Your Mitochondria Protects Your Future Health
Mitochondrial health is central to energy, resilience, and healthy ageing. Addressing it can improve fatigue, cognitive function, and disease risk.
