Chronic Fatigue Explained: Hormones, Micronutrients & Mitochondrial Testing
Chronic fatigue is more than just feeling tired— it’s a persistent lack of energy that doesn’t improve with rest. Many patients are told their blood tests are “normal,” yet symptoms continue. This is where advanced fatigue testing becomes essential, focusing on deeper physiological imbalances. Hormonal health plays a central role in energy regulation. Imbalances in thyroid hormones, cortisol, or sex hormones such as testosterone and oestrogen can significantly impact metabolism, mood, and stamina. Even subtle disruptions can lead to ongoing fatigue. Micronutrient deficiencies are another overlooked cause. Key nutrients like iron, vitamin B12, magnesium, and vitamin D are critical for cellular energy production. Standard tests may miss borderline or functional deficiencies that still affect performance and wellbeing. At the cellular level, mitochondrial function is crucial. Mitochondria are responsible for ...
