Are you feeling tired all the time, experiencing numbness and tingling in your hands and feet, or struggling with memory lapses? You might be surprised to learn that these symptoms could be related to a simple yet common deficiency: vitamin B12.
The Causes of Vitamin B12 Deficiency
Vitamin B12 is an essential nutrient that plays a crucial role in the production of red blood cells, nerve function, and DNA synthesis. However, many people are unaware that they may be deficient in this vital vitamin. In fact, according to the National Institutes of Health, as many as 20% of people over the age of 50 may have vitamin B12 deficiency.
The First Key Cause: Age
As we age, our bodies’ ability to absorb vitamin B12 from food decreases. This is because older adults produce less hydrochloric acid in their stomachs, which is necessary for breaking down the protein-bound vitamin B12 into a form that can be absorbed by the body.
Research has shown that after the age of 50, the risk of vitamin B12 deficiency increases significantly. In fact, a study published in the Journal of Gerontology found that more than half of adults over the age of 60 had low levels of vitamin B12. This is especially concerning for older adults, as vitamin B12 deficiency can increase their risk of cognitive decline and dementia.

However, many people are unaware that they may be deficient in this vital vitamin. In fact, according to the National Institutes of Health, as many as 20% of people over the age of 50 may have vitamin B12 deficiency.

This is especially concerning for older adults, as vitamin B12 deficiency can increase their risk of cognitive decline and dementia.
The Second Key Cause: Diet
Vitamin B12 is primarily found in animal-based foods, such as meat, poultry, fish, eggs, and dairy products. However, a diet that is heavily reliant on plant-based foods or lacks these animal-based sources can increase the risk of deficiency.
This is because many plant-based foods are naturally low in vitamin B12 or contain compounds that inhibit its absorption. For example, some plant-based milk alternatives may not be fortified with vitamin B12, leaving those who consume them at a higher risk of deficiency.
Additionally, some people may have difficulty absorbing vitamin B12 from food due to gastrointestinal disorders such as Crohn’s disease, celiac disease, or gastrectomy. This can lead to a deficiency in this essential nutrient even if they are consuming enough through their diet.
The Third Key Cause: Lifestyle
A sedentary lifestyle and lack of sun exposure can also contribute to vitamin B12 deficiency. Research has shown that people who spend more time indoors and have limited sun exposure may be at a higher risk of deficiency due to the reduced production of intrinsic factor, a protein necessary for vitamin B12 absorption.
Furthermore, certain medications such as proton pump inhibitors (PPIs) and histamine-2 (H2) blockers can reduce stomach acid production, making it more difficult for the body to absorb vitamin B12 from food.
The Final Key Cause: Medical Conditions
Certain medical conditions, such as pernicious anemia, can also cause vitamin B12 deficiency. Pernicious anemia is a condition where the body cannot produce intrinsic factor, making it impossible for the body to absorb vitamin B12 from food.

The Second Key Cause: Diet
Another common cause of vitamin B12 deficiency is a diet that is severely lacking in animal-based foods. Vitamin B12 is found primarily in animal products such as meat, poultry, fish, eggs, and dairy products. Vegetarians and vegans who do not consume these foods may be at risk for deficiency.
A study published in the Journal of Nutrition found that vegetarians who did not consume fortified plant-based milk were more likely to have low levels of vitamin B12 compared to those who did consume such milk. This highlights the importance of a well-planned vegetarian or vegan diet that includes vitamin B12-fortified foods.
The Final Key Cause: Gut Health
A third key cause of vitamin B12 deficiency is poor gut health. The small intestine is responsible for absorbing vitamin B12 from food, and an imbalance in the gut microbiome can impede this process. Research has shown that individuals with irritable bowel syndrome (IBS) or other gastrointestinal disorders are at increased risk for vitamin B12 deficiency.
Now that we’ve explored the causes of vitamin B12 deficiency, it’s time to take action! If you’re experiencing symptoms such as fatigue, numbness, and memory lapses, consult with your healthcare provider about getting tested for a vitamin B12 deficiency. With proper treatment, including supplementation or dietary changes, you can alleviate these symptoms and improve your overall health.
Conclusion
Vitamin B12 deficiency is a common and often overlooked condition that can have serious consequences if left untreated. By understanding the causes of this deficiency – age, diet, and gut health – we can take steps to prevent or address it. Remember, taking care of your overall health starts with a simple blood test.
