This module focuses on interpreting hormonal and metabolic blood markers by integrating laboratory results with clinical history and symptoms. It covers thyroid, glucose-insulin, adrenal, reproductive, lipid, inflammatory, and nutritional biomarkers, along with key patterns of hormonal resistance. The module also explains conventional versus functional ranges and the importance of recognizing interconnected biomarker patterns rather than isolated values. Emphasis is placed on evidence-based nutrition and lifestyle strategies to address metabolic dysfunction, inflammation, stress, and micronutrient deficiencies.
