About Nutritional Status Markers

Nutritional status markers assess your body's levels of essential vitamins, minerals, and nutrients. Key markers include iron studies (ferritin, serum iron, TIBC, transferrin saturation), vitamin D, vitamin B12, folate, magnesium, zinc, and calcium.

Deficiencies in these nutrients can cause a wide range of symptoms including fatigue, weakness, cognitive issues, immune dysfunction, and mood disturbances. Many deficiencies are common even with adequate diet, particularly vitamin D, B12, and iron. Regular testing helps identify and correct deficiencies before they cause significant health problems.

Frequently Asked Questions

What are the most common nutritional deficiencies?
Vitamin D, iron (especially in women), vitamin B12 (especially in vegetarians/vegans and elderly), and magnesium are among the most common deficiencies, even in people eating balanced diets.
What vitamin D level is optimal?
While "normal" is often listed as 50-125 nmol/L (20-50 ng/mL), many experts suggest optimal levels are 75-125 nmol/L (30-50 ng/mL) for best health outcomes. Levels below 50 nmol/L (20 ng/mL) indicate deficiency.
How is iron deficiency different from anemia?
Iron deficiency occurs when iron stores (ferritin) are low. Anemia occurs when hemoglobin is low. You can have iron deficiency without anemia, experiencing fatigue and symptoms before hemoglobin drops.
Which B12 test is most accurate?
Active B12 (holotranscobalamin) is more accurate than total B12, as it measures the biologically active form. Total B12 can appear normal even when active B12 is deficient.
