Vitamin B12 is an essential nutrient that supports several processes your body needs to function properly. It helps form healthy red blood cells and DNA, supports the nervous system, and participates in metabolic reactions that allow your body to use nutrients from food.
While most people get enough B12 through their diet, certain health conditions, medications, dietary patterns, and age-related changes can contribute to low levels. Understanding Vitamin B12 benefits and the signs of a possible deficiency can help you recognize when testing or supplementation may be appropriate.
What Does Vitamin B12 Do for Your Body?
Vitamin B12, also called cobalamin, is a water-soluble vitamin found naturally in animal-derived foods such as meat, fish, eggs, and dairy products. It is also available in fortified foods, supplements, and wellness injections.
Your body needs adequate B12 to maintain normal blood and nerve cells and produce DNA. B12 also supports metabolic reactions involved in processing carbohydrates, fats, and proteins. However, taking additional B12 does not necessarily increase energy when your B12 levels are already adequate.
Key Vitamin B12 Benefits for Your Health
Vitamin B12 contributes to several essential functions, including:
-
Healthy red blood cell production: B12 helps your body produce properly developed red blood cells, which transport oxygen throughout the body.
-
Nervous system function: Adequate B12 supports healthy nerve cells and normal neurological function.
-
DNA synthesis: Your cells require B12 to make DNA, the genetic material found throughout the body.
-
Normal energy metabolism: B12 participates in metabolic processes that help your body use nutrients from food.
Because these functions affect multiple systems, insufficient B12 can produce a wide range of symptoms.
What Causes Vitamin B12 Deficiency?
A vitamin B12 deficiency can develop because of inadequate dietary intake or problems absorbing B12. People who eat little or no animal-derived foods, including some vegans and vegetarians, may be at greater risk. Older adults can also have difficulty absorbing naturally occurring B12 from food.
Other risk factors include pernicious anemia, gastrointestinal conditions such as celiac disease or Crohn’s disease, and certain stomach or intestinal surgeries. Long-term use of some medications, including metformin and acid-reducing medications, can also interfere with B12 absorption.
Because the body stores substantial amounts of B12, deficiency symptoms can sometimes take years to develop.
What Are the Symptoms of Low Vitamin B12?
Possible symptoms of B12 deficiency include:
-
Persistent fatigue or weakness
-
Pale skin
-
Numbness or tingling in the hands and feet
-
Problems with balance
-
Difficulty concentrating
-
A sore or swollen tongue
-
Heart palpitations
Deficiency can cause megaloblastic anemia, which can contribute to fatigue and weakness. Neurological symptoms can also occur even without anemia. Because fatigue has many possible causes, patients seeking fatigue treatment should receive an appropriate medical evaluation rather than assuming low B12 is responsible.
How Do B12 Injections Work?
B12 injections deliver vitamin B12 directly into the body, bypassing the digestive tract. They may be used to correct a diagnosed deficiency, particularly when absorption is impaired or a deficiency is severe.
However, injections aren’t necessary for everyone with low B12. High-dose oral supplementation can also be effective in some cases. A healthcare provider can evaluate your symptoms, medical history, and laboratory results to determine whether injections, oral supplements, or another form of vitamin therapy is appropriate.
