🍽️ Dietary Causes of B12 Deficiency

Vitamin B12 is naturally found in animal products such as meat, poultry, eggs, dairy, and fish. Individuals who follow vegan or vegetarian diets are more prone to deficiency because plant-based foods lack adequate B12.

Solution: Consider fortified foods or a high-quality B12 supplement, especially if you follow a plant-based lifestyle.

🧬 Malabsorption Causes

Even with a balanced diet, some people experience B12 malabsorption due to:

• Pernicious Anemia: An autoimmune condition preventing the stomach from producing intrinsic factor, necessary for B12 absorption.

• Digestive Disorders: Conditions like Crohn’s disease, celiac disease, or bacterial overgrowth in the small intestine interfere with nutrient absorption.

• Gastrointestinal Surgeries: Procedures such as gastric bypass, gastrectomy, or bowel resection can limit B12 absorption.

💊 Medication-Induced Deficiency

Certain medications can interfere with your body's ability to absorb vitamin B12, including:

• Proton Pump Inhibitors (PPIs) and H2 Blockers: Reduce stomach acid needed for B12 absorption.

• Metformin: A diabetes medication known to reduce B12 levels over time.

Tip: If you're on long-term medication, ask your healthcare provider to monitor your B12 levels regularly.

🍷 Other Contributing Factors

• Alcoholism: Chronic alcohol use disrupts nutrient absorption and liver function.

• Aging: As we age, stomach acid production naturally declines, affecting B12 absorption and increasing the risk of deficiency in older adults.
