Vitamin levels in the body serve as crucial biomarkers of nutritional status and overall health. Adequate levels of vitamins are essential for various physiological processes, including metabolism, immune function, and cellular repair. Monitoring vitamin levels through blood tests helps assess nutritional adequacy and identifies deficiencies or excesses that could impact health.

Biomarker measurements of vitamin levels guide dietary recommendations, supplementation strategies, and clinical interventions to optimize health outcomes and prevent deficiencies or toxicities associated with imbalanced vitamin status. Regular monitoring ensures that individuals maintain optimal vitamin levels essential for overall well-being.
