What Causes Vitamin B12 Deficiency and How Can We Address It?

In the intricate tapestry of nutrients that sustain our bodies, B vitamins are essential players, each with a unique role in fostering health and vitality. Among these vital nutrients, vitamin B12, also known as cobalamin, holds a unique position because of its crucial involvement in preserving nerve health, supporting blood cell formation, and enabling DNA synthesis.

However, despite its significance, many people face shortages of this vital vitamin, leading to a range of health issues.


What is Vitamin B12?

Vitamin B12, a crucial water-soluble nutrient, is unique as it's not produced by plants or animals but by certain bacteria in soil and water. Animals obtain it by consuming these bacteria or plants containing them, making meat, fish, eggs, and dairy rich sources of this essential vitamin.


What Causes Vitamin B12 Deficiency?

Dietary Insufficiency: A primary cause of vitamin B12 deficiency is inadequate dietary intake, particularly among individuals following vegetarian or vegan diets who may not consume sufficient amounts of B12-rich foods.Natural foods such as nutritional yeast, yeast spreads, certain mushrooms, and some algae are rich sources of this essential vitamin. For a convenient boost, just one shot of our organic outdoor-grown wheatgrass juice provides more than enough Vitamin B12 to meet your daily recommended intake. 


  1. Malabsorption Issues: Certain medical conditions, such as pernicious anemia, celiac disease, Crohn's disease, and atrophic gastritis, can impair the body's ability to absorb vitamin B12 from food. In pernicious anemia, for instance, the stomach lacks intrinsic factor, a protein necessary for B12 absorption, leading to deficiency despite sufficient dietary intake.
  2. Medications and Procedures: Long-term use of certain medications, such as proton pump inhibitors and metformin, can interfere with B12 absorption. Additionally, surgical procedures involving the removal of parts of the stomach or intestines can compromise B12 absorption, necessitating supplementation to prevent deficiency.
  3. Age-related Decline: As individuals age, their ability to absorb vitamin B12 diminishes, increasing the risk of deficiency, especially among older adults. Consequently, older individuals may require higher B12 intake or supplementation to maintain optimal levels.
  4. Lifestyle Factors: Lifestyle choices, such as excessive alcohol consumption or smoking, can contribute to vitamin B12 deficiency by impairing nutrient absorption or increasing metabolic demand.


Addressing Vitamin B12 Deficiency

Addressing vitamin B12 deficiency entails adopting strategies tailored to the underlying cause:

  • Dietary Modifications: Incorporating B12-rich foods into the diet, such as meat, fish, eggs, dairy, and fortified foods, can help prevent deficiency, particularly for individuals following vegetarian or vegan diets.
  • Supplementation: In cases of malabsorption or dietary limitations, supplementation with vitamin B12 tablets, sublingual formulations, or intramuscular injections may be necessary to ensure adequate intake and prevent deficiency-related complications.
  • Medical Management: Individuals with underlying medical conditions affecting B12 absorption should work closely with healthcare providers to manage their condition effectively and prevent deficiency-related complications.
  • Lifestyle Changes: Adopting a healthy lifestyle, including moderating alcohol consumption, quitting smoking, and managing stress, can support overall well-being and enhance nutrient absorption, including vitamin B12.

Vitamin B12 deficiency can have far-reaching consequences on health, impacting energy levels, nerve function, and red blood cell production. By understanding the various factors contributing to deficiency and implementing targeted interventions, individuals can safeguard their health and vitality.
