The most accurate way to know if your B12 level is low is by getting a blood test. B12 is a nutrient that is found mostly in animal proteins, so if you are vegetarian or follow a vegan diet, you may be at risk for a B12 deficiency.
Signs and symptoms of a B12 deficiency can include feeling exhausted even after a good night’s sleep, tingling or numbness in the arms and legs, difficulty balancing, difficulty thinking clearly, anxiety, depression, a sore and red tongue, pale skin, and anemia.
A blood test can measure your B12 level and help to determine if you are deficient. Your doctor may also order other tests to look for signs of anemia, which can occur if your B12 level is low. If your B12 level is low, your doctor may recommend dietary changes to increase your B12 intake, as well as supplements if necessary.

What is the main cause of low B12?
The main cause of low B12 levels is a dietary deficiency – either not consuming enough B12-rich foods or not absorbing enough of it from food. People following a plant-based diet, such as vegans and some vegetarians, are easily prone to B12 deficiency since this vitamin is mainly found in animal-based foods, like meat, eggs, dairy, and seafood.
The inability to absorb vitamin B12 from the gut can also be a cause of insufficient amounts of the nutrient. This occurs when someone has a limited ability to absorb Vitamin B12 due to a condition known as atrophic gastritis.
This is the inflammation of the stomach wall and can lead to a decreased production of certain chemical components needed to extract B12 from food effectively.
Others may suffer a deficiency due to medication like antacids, proton pump inhibitors, and H2 receptor blockers which are prescribed to reduce stomach acid and thus can reduce the body’s ability to absorb Vitamin B12 from food.
Additionally, alcoholism, parasites, and gut infections can diminish the body’s ability to absorb B12 from foods that contain it, resulting in deficiency.
Finally, as we age, our bodies may have a harder time absorbing B12. This is why it is important for people over 50 to get a blood test to check their B12 levels.
Why would a persons B12 be low?
A person’s B12 could be low for a variety of reasons. Generally, B12 deficiency is caused by a lack of the vitamin in the diet, or difficulty absorbing it from food — a problem called malabsorption. Malabsorption can be caused by conditions such as Crohn’s disease, celiac disease, bacterial growth in the small intestine, and pernicious anemia—an autoimmune disorder that destroys the stomach cells needed to absorb the B12 vitamin.
People who have had intestinal surgeries, such as weight loss surgery, may also not absorb enough B12.
Other causes of B12 deficiency can include long-term use of acid-reducing medications such as proton pump inhibitors or H2 blockers, heavy drinking, anemia, and conditions that affect the immune system such as HIV/AIDS and lupus.
Vegans and vegetarians also tend to have a higher risk of B12 deficiency due to limited food sources. Elderly people are also at an increased risk, since their bodies may not absorb B12 as well.
Should I be worried if my B12 is low?
Yes, it is important to be concerned if your B12 levels are low. B12, or cobalamin, is a vital nutrient that helps your body function properly on multiple levels. It is particularly important for energy production, brain and nerve functioning, red blood cell formation, and other metabolic processes.
Low levels of B12 can lead to a variety of health issues such as anemia, fatigue, memory loss, and nerve damage. Therefore, it is important to get tested for B12 deficiency, and if it is found to be low, talk to your doctor about the best course of treatment.
This can include changes in diet, supplementation, or other recommendations. It is important to stay vigilant with B12 levels and address any deficiencies as soon as possible, in order to prevent any long-term health risks.
What happens if vitamin B12 is low in adults?
If an adult has a vitamin B12 deficiency, they can experience a variety of symptoms. These include fatigue, weakness, constipation, loss of appetite, weight loss, tingling and numbness in the hands and feet, balance problems, depression, confusion, dementia, and soreness of the mouth or tongue.
A vitamin B12 deficiency can also cause anemia, which can lead to pale skin, shortness of breath, and a faster heart rate.
If the deficiency is not corrected, long-term health problems can occur such as nerve damage and other irreversible changes in the brain or spinal cord. A vitamin B12 deficiency can also increase the risk for some types of cancer, heart disease, and stroke.
It is important to address a vitamin B12 deficiency quickly to avoid the potential long-term health risks. A doctor can diagnose a vitamin B12 deficiency through a physical exam and blood test. Treatment involves taking supplements and adding more vitamin B12-rich foods to the diet.
Foods that are especially high in B12 include meats, fish, shellfish, eggs, and dairy products.
How can I raise my B12 levels fast?
In order to raise your B12 levels fast, it is important to focus on lifestyle changes that can help you increase your intake of B12. Here are some tips to help you raise B12 levels quickly and safely:
1. Increase your intake of B12-rich foods. Some of the top B12-rich foods are beef, lamb, fortified breakfast cereals, salmon, tuna, oysters, dairy products, and eggs. Additionally, certain plant-based milks, such as almond and soy, are fortified with B12.
Eating foods like these on a daily basis can help you maintain healthy B12 levels.
2. Take B12 supplements. You can purchase B12 supplements in pill or liquid form at many health food stores and pharmacies. Taking a daily B12 supplement can help ensure you’re getting an adequate amount of B12.
3. Have your doctor check your B12 levels. If your diet doesn’t provide adequate amounts of B12, your doctor may be able to help. Your doctor may recommend that you take a B12 injection or prescribe B12 supplements to you.
By following these tips, you can help raise your B12 levels quickly and safely. It is important to note, however, that it is always best to talk with your doctor before beginning any new supplements.
What prevents the absorption of vitamin B12?
The absorption of vitamin B12 can be prevented by various conditions including pernicious anemia, atrophic gastritis, prior gastric surgery, malabsorption syndromes such as Crohn’s disease, and long-term use of certain medications such as metformin, proton pump inhibitors (PPIs), and histamine H2 receptor blockers.
Pernicious anemia, for example, is an autoimmune disorder where the body does not produce enough intrinsic factor to facilitate the absorption of B12, resulting in vitamin B12 deficiency. Atrophic gastritis is a degenerative condition in which the inner lining of the stomach gets thinner due to inflammation, further reducing the production of intrinsic factor, gastric acid and pepsin, which are all essential for B12 absorption.
In addition, long-term use of certain medications such as PPIs and H2 receptor blockers can interfere with B12 absorption due to reduction in stomach acid, while Crohn’s disease and other malabsorption syndromes create difficulty in absorbing vitamins, minerals, and other nutrients due to inflammation and destruction of the small intestine.
In all of these cases, obtaining adequate levels of vitamin B12 through diet or supplementation may be necessary in order to prevent health complications related to vitamin B12 deficiency.
What does low B12 feel like?
Low B12 can cause many different symptoms and signs that can vary greatly person to person. Some of the most common signs of low B12 include feeling tired and weak, having difficulty thinking clearly, having anemia, having a decrease in appetite and weight loss, feeling tingling or numbness in the hands and feet, having difficulty walking or balancing, pale or yellowish skin, and having a sore, red tongue.
In more severe cases, low B12 can cause confusion, dementia-like symptoms, and depression. If you suspect you may have low B12, it is important to speak to your healthcare provider and get tested since anemia or other conditions can also cause some of these symptoms.
Treatment for low B12 includes B12 injections or taking B12 supplements. It is important to follow your healthcare provider’s instructions for treatment and monitor for any changes in symptoms.
What autoimmune disorders cause low B12?
Autoimmune disorders that can cause low vitamin B12 levels include pernicious anemia, Addison’s disease, Graves’ disease, Hashimoto’s thyroiditis, celiac disease, and lupus. Pernicious anemia is caused when the immune system attacks the cells in the stomach that produce intrinsic factor, which is a protein necessary for proper absorption of vitamin B12.
Addison’s disease causes inflammation and destruction of the cells in the adrenal glands that produce hormones needed for vitamin B12 absorption and utilization. Graves’ disease leads to overactive thyroid and decreased absorption of B12.
Hashimoto’s thyroiditis is an autoimmune disease of the thyroid gland and can result in reduced ability to absorb vitamin B12. Celiac disease is an immune-mediated disorder which can impair absorption of B12 and lead to low B12 levels.
Lupus is an autoimmune disorder in which inflammation of the small intestine can also lead to deficiency of B12. All of these autoimmune conditions can cause a deficiency of B12 which can cause symptoms such as fatigue, shortness of breath, memory problems, weak muscles, and balance problems.
Which fruit is rich in vitamin B12?
Vitamin B12 is found naturally in animal-sourced foods such as beef liver, fish, egg yolks, beef, shellfish, chicken, and yogurt. While you won’t find any fruits that contain more than trace levels of B12, dried nori is a type of seaweed commonly consumed in Japan that contains good amounts of this essential nutrient.
Other plant-based sources of B12 include nutritional yeast, fortified plant-based milks, and some breakfast cereals.
Can B12 deficiency make you feel unwell?
Yes, B12 deficiency can make you feel unwell. B12 is an essential vitamin that plays an important role in red blood cell formation and brain/nervous system function. When you’re deficient in B12, you can experience a variety of physical and mental symptoms related to anemia and nerve damage.
Common signs and symptoms of B12 deficiency include fatigue, depression, numbness and tingling in the extremities, nerve damage, cognitive difficulties, pale skin, shortness of breath, and digestive problems.
In severe cases, B12 deficiency can even lead to anemia and even permanent nerve damage if left untreated. If you think you may be deficient in B12, it’s important to speak to your doctor to have your levels tested.
Do you feel dizzy with B12 deficiency?
Yes, people with B12 deficiency can feel dizzy and lightheaded. B12 deficiency can cause anemia, which occurs when the body does not have enough healthy red blood cells. Red blood cells are responsible for carrying oxygen and other nutrients throughout the body.
When there isn’t enough oxygen being delivered to the brain, an individual can experience dizziness and lightheadedness. B12 deficiency can also lead to neurological symptoms such as difficulty walking, balance problems, confusion, memory problems and tingling or numbness in the hands and feet.
If you are experiencing any of these symptoms, it is important to contact your healthcare provider to have your B12 levels tested.
What blocks B12 absorption?
The absorption of Vitamin B12 can be blocked due to a variety of factors, such as chronic gastritis or an autoimmune disorder called pernicious anemia. Gastritis is an inflammation or irritation of the lining of the stomach, which can interfere with the body’s ability to produce certain digestive enzymes (called intrinsic factor) that are required for the digestion of Vitamin B12.
Likewise, pernicious anemia is an autoimmune disorder in which the body’s immune system attacks the cells that produce intrinsic factor, which can also interfere with the digestion of Vitamin B12.
Additional causes of Vitamin B12 malabsorption can include celiac disease, gastric bypass surgery, use of antacid medications, and Helicobacter pylori infection, to name a few. Additionally, certain genetic mutations can impair absorption of Vitamin B12, or lead to an increased dietary requirement for this essential nutrient.
In such cases, the inability to absorb Vitamin B12 can cause Vitamin B12 deficiency and produce a variety of symptoms, including fatigue, difficulty concentrating, and anemia.
What is B12 in blood test called?
A B12 blood test is a laboratory test that measures the amount of vitamin B12 in your blood. It can detect deficiency, which can lead to anemia and other medical issues. The test is also used to evaluate levels in people with conditions that affect B12 absorption, such as certain digestive disorders, or conditions which prevent the body from adequately utilizing the vitamin, such as certain autoimmune disorders.
A healthy B12 level is important for overall health and wellbeing. Lack of B12 can cause anemia, neurological issues, and difficulty with learning and memory. As such, getting a B12 blood test is important for diagnosing any issues related to B12.
What does CBC look like with B12 deficiency?
A CBC (complete blood count) can provide a snapshot of how your body is functioning. It includes a test of the different types of blood cells and gives information on red blood cells, white blood cells, and platelets.
When someone has a B12 deficiency, a CBC can indicate a low red blood cell count (anemia), as well as a low hemoglobin and hematocrit. A CBC can also detect abnormal levels of certain types of white blood cells.
If a patient has a B12 deficiency, their white blood cell count may be reduced, due to a decrease in production of certain types of white blood cells. Additionally, a CBC may show an increase in the mean corpuscular volume (MCV).
This is an indicator of the size of the red blood cells, and an increase in MCV can be seen in cases of B12 deficiency. A CBC can also indicate the platelet count, which may be lower in B12 deficiency, as platelet production is affected.
