What are the causes of vitamin B12 deficiency?

Vitamin B12 deficiency occurs when the body does not have enough B12 to function properly. This can happen when a person does not consume enough B12 in their healthy diet or if their body cannot properly absorb it. Some of the common causes of B12 deficiency include:

Vegan or vegetarian diet

Since B12 is primarily found in animal products, those who follow a vegan or vegetarian diet may not get enough B12 in their diet.

Gastrointestinal disorders

Conditions that affect the digestive system, such as celiac disease, Crohn's disease, or other gastrointestinal disorders, can affect the body's ability to absorb B12.

Aging

As people age, their stomachs may produce less acid, which can also decrease the body's ability to absorb B12.

Certain medications

Some medications, such as proton pump inhibitors and metformins, can affect the absorption of B12.

Primarily Vitamin B12 is found in animal-based foods, here are some of them:

Meat

Beef, liver, lamb, and pork are all good sources of B12.

Fish

Salmon, trout, and tuna are good sources of B12.

Poultry

Chicken, turkey, and eggs contain B12.

Dairy products

Milk, cheese, and yogurt are good sources of B12.

Vegetarian and vegan sources of B12 are limited, but some plant-based foods are fortified with B12, including:

Nutritional yeast

A type of yeast that is commonly used as a cheese substitute and is often fortified with B12.

Fortified cereals

Some cereals are fortified with B12.

Plant-based milk alternatives

Some plant-based milk alternatives, such as soy milk and almond milk, are fortified with B12.

It is important to note that these fortified sources may not provide enough B12 for people who have a deficiency or follow a strict vegan or vegetarian diet. In these cases, B12 supplements or injections may be necessary to meet daily B12 requirements.
