Nutrient & Vitamin Lab Tests
Nutrient and vitamin lab tests measure your body’s actual stores, like vitamin D and iron (ferritin), rather than what you eat, revealing shortfalls that food logs miss. Deficiencies in these markers are among the most common and most correctable findings on routine blood work. This hub explains the key nutrient biomarkers, commonly used cutoffs, and when retesting makes sense.
