Introduction
If you’ve recently had a blood test and your Mean Corpuscular Volume (MCV) was low, you might be wondering what it means and how to improve it. MCV measures the average size of your red blood cells, and low levels can indicate certain health concerns. With the right diet and lifestyle changes, you can often increase your MCV levels naturally.
What Is MCV?
MCV stands for Mean Corpuscular Volume, which is a part of your Complete Blood Count (CBC) test. It tells doctors about the size of your red blood cells:
Normal MCV (80–100 fL): Healthy-sized red blood cells.
Low MCV (<80 fL): Smaller than normal (microcytic anaemia).
High MCV (>100 fL): Larger than normal (macrocytic anaemia).
A low MCV often suggests iron deficiency or chronic disease, while a high MCV may indicate vitamin B12 or folate deficiency.
Causes of Low MCV
Several factors can lead to smaller red blood cells (low MCV), including:
1. Iron Deficiency Anaemia – The most common cause, often due to poor diet, blood loss, or poor absorption.
2. Chronic Diseases – Conditions like kidney disease or inflammatory disorders can affect red blood cell production.
3. Thalassemia – A genetic condition affecting haemoglobin production.
4. Lead Poisoning – Rare but can interfere with red blood cell formation.

How to Increase MCV Naturally
If your MCV is low, here are some effective ways to improve it:
1. Eat Iron-Rich Foods
Iron is essential for healthy red blood cells. Include:
Heme Iron (better absorbed): Red meat, chicken, fish, especially liver.
Non-heme Iron (plant-based): Spinach, lentils, beans, tofu, nuts, and fortified cereals.
Pair iron-rich foods with vitamin C from oranges, bell peppers, and tomatoes to boost absorption.
2. Increase Vitamin B12 & Folate
Deficiencies in these vitamins can also affect MCV.
Vitamin B12 sources: Eggs, dairy, fish, fortified cereals.
Folate sources: Leafy greens, citrus fruits, beans, whole grains.
3. Avoid Iron Blockers
Some foods and drinks can reduce iron absorption:
Coffee & tea are best consumed between meals, not with iron-rich foods.
Avoid taking calcium-rich foods like milk and cheese with iron-rich meals.
4. Consider Supplements (If Needed)
If diet alone isn’t enough, your doctor may recommend:
Iron supplements like ferrous sulphate or ferrous gluconate.
B12 injections or supplements, if deficiency is severe.
5. Manage Underlying Conditions
If chronic illness (like kidney disease or inflammation) is causing low MCV, treating the root cause is essential.
6. Stay Hydrated & Exercise Moderately
Proper hydration supports blood health, while moderate exercise improves circulation and oxygen delivery.
When to See a Doctor
If your MCV remains low despite dietary changes, consult a doctor to rule out:
Internal bleeding (e.g., ulcers, heavy periods).
Malabsorption issues (e.g., celiac disease, Crohn’s disease).
Genetic conditions (e.g., thalassemia).

Final Thoughts
A low MCV is often linked to iron or vitamin deficiencies, but with the right diet and medical guidance, it can be corrected. Focus on nutrient-rich foods, avoid iron blockers, and monitor your health with regular check-ups.
