Are you taking vitamin B12 supplements?

Certain foods can interfere with the absorption or utilization of vitamin B12. If you're taking vitamin B12 supplements, consider moderating or avoiding the following foods:

Avoid foods rich in fiber

Foods high in fiber, particularly soluble fiber, can interfere with the absorption of B12. Fiber binds with B12 and prevents its absorption in the small intestine.

Avoid coffee and tea

Substances found in coffee and tea, such as tannins, can inhibit the absorption of B vitamins, including B12. Consuming these beverages around the same time as your B12 supplements may reduce their effectiveness.

Calcium-rich foods

Calcium competes with B12 for absorption. High-calcium foods, like dairy products and fortified plant-based milks, may interfere with B12 absorption.

Avoid having antacids

Medications used to reduce stomach acid, such as antacids and PPIs, can interfere with the release of B12 from food.

Do not consume alcoholic beverages

Chronic alcohol consumption can impair the absorption and utilization of B12. Alcohol may damage the stomach lining, reducing its ability to produce intrinsic factor, a substance necessary for B12 absorption.

Stop eating spicy foods

Spicy foods, particularly those containing hot peppers, can irritate the stomach lining. Chronic irritation may impact the stomach's ability to produce intrinsic factors, affecting B12 absorption.

Certain medications inhibit absorption of the vitamin

Some medications may interfere with B12 absorption or utilization. These include certain antibiotics, colchicine (used to treat gout), and certain anticonvulsant medications.

Avoid high protein consumption

Very high protein intake, especially from animal sources, may affect the absorption of B12. While protein is essential, balance is key.

Avoid processed foods

Highly processed foods may lack the natural B12 found in whole foods. Relying on a diet high in processed foods may contribute to nutrient deficiencies, including B12.
