Fatigue Bundle

Comprehensive assessment to help uncover the underlying causes of persistent tiredness or low energy by evaluating key biomarkers related to energy production, metabolism, and hormone balance. Persistent fatigue can significantly impact daily life and may stem from various underlying health issues. The Fatigue Bundle is designed to identify potential causes such as nutrient deficiencies, thyroid imbalances, or chronic inflammation by analysing specific biomarkers.
