When the body has an excess amount of vitamin B12, it is known as hypervitaminosis B12. This condition is relatively rare, and it can occur when someone takes high doses of vitamin B12 supplements or has an underlying health condition that causes them to absorb more B12 than they need.
The primary function of vitamin B12 in the body is to help create DNA and red blood cells, as well as support the normal functioning of the nervous system. However, when someone takes excessive amounts of this vitamin, it can lead to a range of symptoms and health problems.
Some of the symptoms associated with hypervitaminosis B12 include:
– Skin rash
– Nausea and vomiting
– Diarrhea
– Fatigue
– Headaches
– Anxiety
– Insomnia
– Joint pain
In severe cases, high levels of vitamin B12 can affect the functioning of the nervous system, leading to neurological symptoms such as difficulty walking, confusion, and numbness in the limbs.
While rare, hypervitaminosis B12 can occur, so it is important to be mindful of how much vitamin B12 you are getting from your diet and any supplements you may be taking. Generally, it is safe to consume B12 through food sources, such as meat, fish, and dairy products, but supplements should only be taken under the guidance of a healthcare provider.
If you suspect you may be experiencing symptoms of hypervitaminosis B12, it is important to speak with your doctor to determine the underlying cause and develop an appropriate treatment plan.

What happens if your B12 is too high?
Vitamin B12 is an essential nutrient that plays a crucial role in maintaining normal body function, including the development of red blood cells, nerve cells, and DNA synthesis. However, having too much of this vitamin in the body can lead to potential health risks.
High levels of vitamin B12 in the bloodstream, also known as hypercobalaminemia, can be caused by several factors, including excessive intake of vitamin B12 supplements, liver disease, and kidney failure. In some cases, it can also be a sign of underlying medical conditions, such as leukemia, lymphoma, or other blood disorders.
One of the significant risks associated with high B12 levels is the potential for masking an underlying deficiency in folate (vitamin B9). Because both vitamins are involved in the formation of red blood cells, excessive B12 intake can lead to a high red blood cell count, while folate deficiency may go unnoticed.
Another potential risk of high levels of vitamin B12 is its impact on the nervous system. Although rare, high levels of B12 have been linked to neurological symptoms such as numbness, tingling sensations, and nerve damage.
Furthermore, studies have suggested that elevated levels of vitamin B12 may be associated with an increased risk of developing certain types of cancers, such as prostate, lung, and colon cancer. However, more research is needed to confirm this link.
While vitamin B12 is a necessary nutrient for the human body, having too much of it can pose potential health risks. If you suspect that you have elevated levels of this vitamin in your bloodstream, it’s recommended that you seek medical advice to determine the underlying cause and appropriate treatment.
Should I be worried if my B12 is high?
The answer to this question largely depends on why your B12 is high. In some cases, elevated B12 levels may be a sign of a health problem, while in other cases, they may simply be indicative of dietary or supplement habits.
One possible cause of high B12 levels is liver disease. The liver is responsible for storing excess B12, and if it is damaged or diseased, it may release large amounts of B12 into the bloodstream. Similarly, some types of cancer can cause elevated B12 levels, as the cancer cells often produce large amounts of the vitamin.
However, in many cases, high B12 levels may simply be the result of dietary or supplement choices. Certain foods, such as meat and dairy products, are high in B12, and taking B12 supplements can also contribute to elevated levels. Even though it is not likely to cause any harm, if you are not deficient in Vitamin B12, supplementing in excess can have side effects such as nausea, vomiting, diarrhea, and skin rashes.
It is important to consult your healthcare provider to understand the underlying cause of your high B12 levels. If they are due to liver disease or cancer, it is important to address these underlying conditions. On the other hand, if your B12 levels are simply the result of dietary or supplement habits, your healthcare provider may recommend adjusting your diet or supplements to reach a healthy balance.
Regardless of the cause, it is prudent to regularly discuss blood test results with your healthcare provider to ensure that you are overall in good health.
How can I reduce my B12 levels?
Before answering the question on how to reduce B12 levels, it is essential to understand that B12 is an essential vitamin required by the body for various functions. The recommended daily intake of B12 for adults is 2.4 mcg, and anything above this is considered normal. However, if a person has B12 levels above the normal range or is experiencing symptoms of B12 toxicity, they may need to take measures to lower their B12 levels.
One of the most effective ways to reduce B12 levels is to decrease the intake of B12-rich foods, such as meat, shellfish, eggs, and dairy products. If a person is a vegan or vegetarian and relies heavily on fortified foods or supplements for B12, they can reduce their intake of these products or switch to a lower dose supplement to decrease their B12 levels.
Another way to reduce B12 levels is to stop taking B12 supplements. While B12 supplements are generally safe, taking high doses of B12 supplements can lead to elevated B12 levels. If a person is taking a B12 supplement due to a deficiency, they should consult with their healthcare provider to determine the appropriate dose.
It is also essential to avoid B12 injections unless prescribed by a healthcare provider. B12 injections deliver a high dose of B12 directly into the bloodstream, which can cause B12 levels to rise quickly.
Lastly, people with high B12 levels should consider undergoing genetic testing to determine if they have a rare condition called CBL C deficiency or transcobalamin deficiency. These genetic conditions affect the body’s ability to metabolize B12 and can cause elevated B12 levels. If a person is diagnosed with one of these conditions, their healthcare provider can develop a treatment plan tailored to their specific needs.
While B12 is an essential vitamin, elevated B12 levels can be harmful. To reduce B12 levels, a person can decrease their intake of B12-rich foods, stop taking B12 supplements, avoid B12 injections, and undergo genetic testing to determine if they have an underlying health condition. However, it is important to discuss any concerns or changes in diet or supplements with a healthcare provider before making any significant changes.
Does high B12 mean liver damage?
No, high B12 levels in the blood do not necessarily indicate liver damage. Vitamin B12 is a water-soluble vitamin that is essential for the proper functioning of the nervous system and the production of red blood cells. It is primarily derived from animal-based foods such as meat, dairy, and eggs, and is stored in the liver.
Liver damage can cause an elevation in liver enzymes such as ALT, AST, and ALP in the blood. However, B12 levels are not a direct indicator of liver function or damage. Rather, high B12 levels may be due to other factors such as excessive intake of B12 supplements, underlying medical conditions such as leukemia, liver disease, or kidney dysfunction, or certain medications that can interfere with the absorption and metabolism of B12.
In addition, some people may have a genetic condition known as transcobalamin II deficiency, which causes B12 to accumulate in the blood and result in elevated B12 levels. Therefore, it is important to evaluate high B12 levels in conjunction with other clinical and laboratory parameters to determine the underlying cause and potential significance.
While liver damage can cause abnormal laboratory values, high B12 levels do not necessarily indicate liver damage and require further examination by a healthcare provider.
What cancers cause high B12 levels?
Cancer is a group of diseases that are characterized by uncontrolled growth and spread of abnormal cells. While cancer can cause various complications in the body, it is not typically associated with increased levels of vitamin B12 and can be characterized by normal, elevated, or even low levels.
However, in rare cases, some types of cancer may cause an elevation in serum vitamin B12 levels due to the overproduction of certain proteins related to metabolism, inflammation, and cell growth. Some of these cancers include:
1. Liver Cancer:
Liver cancer, also known as hepatocellular carcinoma, is a type of cancer that develops in the liver cells. This type of cancer can cause high levels of vitamin B12 due to its ability to synthesize certain proteins involved in vitamin B12 metabolism.
2. Leukemia:
Leukemia is a cancer of blood cells that affect the production of bone marrow cells. High levels of vitamin B12 can occur in cases of chronic myelogenous leukemia due to the overproduction of vitamin B12-binding proteins, which can cause an increase in serum vitamin B12 levels.
3. Lymphoma:
Lymphoma is a cancer of the lymphatic system which includes the lymph nodes, spleen, and bone marrow. High levels of vitamin B12 can occur in certain cases of lymphoma due to the production of certain types of immune cells that can produce vitamin B12 in the body.
4. Pancreatic Cancer:
Pancreatic cancer is a type of cancer that affects the pancreas, an organ responsible for producing digestive enzymes and hormones such as insulin. High levels of vitamin B12 can be observed in some pancreatic cancers due to the production of certain proteins in the pancreas that are involved in vitamin B12 metabolism.
Although high levels of vitamin B12 are not typical of most cancers, certain types of cancers such as liver cancer, leukemia, lymphoma, and pancreatic cancer can cause elevated levels of vitamin B12 due to the overproduction of certain proteins related to metabolism, inflammation, and cell growth. It is important to note that other medical conditions such as liver and kidney diseases, as well as vitamin B12 supplementation, can also contribute to increased levels of vitamin B12 in the body.
What level of B12 is concerning?
The level of B12 in the blood that is considered concerning may vary depending on the individual’s age, overall health, and any underlying medical conditions they may have. Generally, a B12 level below 200 pg/mL is considered low and may indicate a deficiency. However, some doctors may consider levels between 200-350 pg/mL as borderline low and may recommend further testing and monitoring for symptoms of deficiency.
People who are at a higher risk of B12 deficiency, such as vegetarians and vegans, elderly individuals, those with gastrointestinal disorders, and those who have undergone weight loss surgery, may have lower baseline levels compared to the general population. In such cases, even levels above 350 pg/mL may be considered concerning if there are symptoms of deficiency or if the individual’s levels have significantly decreased over time.
Symptoms of B12 deficiency may include fatigue, muscle weakness, numbness or tingling in the hands and feet, difficulty walking or maintaining balance, mood changes, and cognitive deficits. If left untreated, severe deficiency can result in irreversible nerve damage and other serious health complications.
Therefore, it is important to monitor B12 levels regularly and discuss any concerning results with a healthcare provider to determine the appropriate treatment and management plan. Depending on the individual’s level of deficiency, treatment may include dietary changes, oral supplements, or injections.
Is B12 a tumor marker?
B12, also known as vitamin B12, is not typically considered a tumor marker. Tumor markers are substances that can be detected in the blood, urine or tissue of individuals with cancer, which may indicate the presence or progression of cancer. These markers are specific to certain types of cancer and are used alongside other diagnostic tools such as imaging tests and biopsies.
B12, on the other hand, is an essential vitamin that plays a crucial role in the proper functioning of the nervous system, red blood cell formation, and DNA synthesis. It is primarily obtained from animal-based foods and is vital for maintaining a healthy body. However, it is possible that B12 levels may be altered in cancer patients as some cancers can interfere with the absorption of nutrients in the digestive system, including vitamins like B12.
While B12 itself is not considered a tumor marker, some studies have examined the association between B12 levels and various types of cancer. For instance, low B12 levels have been linked to increased risk of developing gastric cancer, and several studies have suggested that low B12 levels may also be associated with an increased risk of breast cancer.
However, more research is needed to determine the precise relationship between B12 and cancer.
While B12 is not typically used as a tumor marker, changes in B12 levels may be indicative of other health conditions, including some forms of cancer. Anyone with concerns about their B12 levels or overall health should speak with their healthcare provider for guidance on appropriate testing and treatment options.
Can multiple myeloma cause high B12?
Multiple myeloma is a type of blood cancer that occurs when plasma cells, a type of white blood cell found in the bone marrow, start to grow uncontrollably, leading to the overproduction of abnormal proteins. This can eventually lead to the development of tumors in the bone marrow, which can cause a range of symptoms such as bone pain, anemia, fatigue, and impaired kidney function.
In terms of B12 levels, multiple myeloma can interfere with the body’s ability to absorb and utilize this essential vitamin, leading to deficiencies. This is because the abnormal proteins produced by cancer cells can bind with and sequester B12, preventing it from being absorbed by the body.
However, in some cases, multiple myeloma can also cause elevated levels of B12, a condition known as hypercobalaminemia. This is thought to occur because cancer cells produce large amounts of a protein called transcobalamin II (TC II), which binds with B12 to transport it through the bloodstream. As a result, higher levels of TC II can lead to higher levels of B12 in the blood.
It’s important to note, though, that hypercobalaminemia can also be caused by other factors such as liver disease, kidney disease, and certain medications, so additional tests may be needed to confirm a diagnosis of multiple myeloma.
While multiple myeloma can interfere with B12 absorption and lead to deficiencies, it can also cause elevated levels of B12 due to the overproduction of TC II. However, further tests may be required to confirm a diagnosis, since hypercobalaminemia can also be caused by other underlying conditions.
How do you get rid of too much B12 in your body?
Getting rid of too much B12 in the body can be a bit tricky since B12 is a water-soluble vitamin, and its excess gets excreted through the urine. However, there are a few ways to lower the B12 levels in the body, and they include:
1. Stop taking B12 supplements: If you have been taking B12 supplements, it’s important to talk to your doctor before discontinuing them abruptly. They may advise you on how to gradually taper off the dosage or switch to a lower dose.
2. Change your diet: If you get too much B12 from your diet, you can adjust your food intake to lower it. For instance, you can reduce your intake of meat, eggs, dairy products, shellfish, and fortified breakfast cereals which are rich sources of vitamin B12.
3. Drink more water: Since B12 is excreted through urine, increasing your water intake can help flush out any excess in the body.
4. Consult a doctor: If the B12 levels in your body are too high, your doctor may run some tests to determine if there’s an underlying condition that’s causing it. Depending on the cause, they may propose some treatment options like medication or dietary changes.
If you suspect that you have too much B12 in your body, it’s essential to consult a doctor for proper diagnosis and treatment. Trying to lower the B12 levels on your own without proper guidance can lead to more harm than good.
How long does it take to flush out B12?
Vitamin B12 is a water-soluble vitamin that is an essential nutrient for the body. It is responsible for the production of red blood cells, proper functioning of the nervous system, and the metabolism of food. The body does not produce vitamin B12 naturally, and it is only acquired through the consumption of certain foods or supplements.
The half-life of B12 in the bloodstream is approximately 6 days. This means that if a person stops taking B12 supplements or consuming B12-rich foods, half of the B12 in their bloodstream will be eliminated in about 6 days. However, it can take several months to completely flush out all the B12 from the body.
The rate at which B12 is eliminated from the body can be influenced by a person’s age, gender, diet, and overall health. For example, older adults may have a more difficult time absorbing B12 due to decreased stomach acid production, while individuals with certain medical conditions such as Crohn’s disease or celiac disease may also experience difficulties absorbing B12.
It is important to note that B12 deficiency is a serious health condition that can lead to nerve damage, anemia, and other health problems. Therefore, it is recommended that people who are at risk for B12 deficiency or have been diagnosed with a deficiency seek medical advice and follow the recommended treatment plan.
The length of time it takes to flush out B12 from the body can vary depending on individual factors. However, it is essential to ensure that an adequate amount of B12 is consumed through diet or supplements to maintain proper health and prevent deficiency.
Should I worry about high B12 levels?
If you have found out that you have high levels of vitamin B12, it is important to understand why this has occurred before worrying about it since there could be multiple reasons as to why your B12 levels have increased. While vitamin B12 is essential for the overall functioning of the body, higher levels of this vitamin might indicate an underlying health issue.
One potential reason for high B12 levels is excessive supplementation of the vitamin. Some people may take vitamin B12 supplements to treat a deficiency or to improve their overall health. However, if the supplements are taken unnecessarily, consistently or in large doses, it can lead to a build-up of the vitamin in the body, increasing the B12 levels.
Alternatively, high levels of B12 can be caused by underlying health conditions such as liver disease, leukemia, or even diabetes. It can also be indicative of kidney or bone marrow disorders. In these cases, it is important to consult a healthcare professional to identify and treat the root cause.
While it is necessary to investigate the underlying cause of high levels of B12, some symptoms that might accompany this condition include dizziness, palpitations, joint pain, and skin rashes. If you experience these symptoms, it is important to seek medical attention immediately.
High levels of vitamin B12 should be taken seriously, and it is essential to identify and treat the underlying cause of the condition. In case of excessive supplementation, adjusting the dosage or discontinuing the supplement may be necessary. Therefore, it is essential to consult a healthcare professional to determine the reason behind high levels of vitamin B12 before resorting to worrying.
How to decrease B12 levels?
Before discussing the methods to decrease B12 levels, it is important to understand why one may want to do so. B12 or vitamin B12 is an essential nutrient required by the body for various vital functions, including the formation of red blood cells, DNA synthesis, and proper functioning of the nervous system.
However, excessive levels of B12 in the body may be harmful and can lead to various health problems.
High levels of B12 in the body can be caused by various reasons, including excess intake of B12 supplements or foods rich in B12, liver diseases, kidney problems, or certain medical conditions like leukemia, lymphoma, or bone marrow disorders.
To lower B12 levels, the first step is to identify the underlying cause of increased B12 levels. If the elevated levels are due to excessive intake of B12 supplements, reducing or stopping the supplementation can help. Similarly, if the cause is dietary intake, reducing the intake of foods rich in B12, such as eggs, milk, beef, and fish, can help decrease B12 levels in the body.
If the high B12 levels are due to underlying health conditions, treating or managing the underlying condition is essential. In some cases, medications or therapies may be prescribed to reduce B12 levels in the body, depending on the severity of the condition.
It is important to note that reducing B12 levels should only be done under the supervision of a healthcare professional. Since B12 is an essential nutrient, reducing levels too much can have adverse health effects. Therefore, it is critical to determine the underlying cause and manage it properly to avoid any complications.
High levels of B12 can be harmful, and reducing the levels should be done under the guidance of a healthcare professional. Identifying the underlying cause and managing it appropriately, along with reducing B12 intake, can help lower B12 levels.
Is there any medicine to reduce B12?
Vitamin B12 or cobalamin is an essential nutrient needed for nerve function, DNA synthesis, and the formation of red blood cells. It is obtained through dietary sources or supplements and is stored in the liver.
While there may be instances where an excess of vitamin B12 can be harmful, the body has a natural mechanism to regulate its absorption and excretion. Therefore, there is no medication available to reduce vitamin B12 levels in the body.
However, certain medical conditions, such as liver disease or kidney disease, may result in elevated levels of B12. In such cases, the underlying condition needs to be addressed, and vitamin B12 levels are generally managed through dietary changes or supplements.
Moreover, other factors such as age, genetics, and lifestyle habits can also affect B12 levels in the body. Therefore, it is always advisable to consult a healthcare professional if there are concerns about B12 levels in the body.
There is no medication to reduce vitamin B12 levels in the body, and it is vital to maintain an appropriate balance of this essential nutrient for optimal health. Therefore, individuals must ensure they are consuming sufficient vitamin B12 through their diet or supplements and consult a healthcare professional for any related concerns.
What medications can lower B12?
There are several medications that can potentially lower B12 levels in the body. One of the most commonly known culprits is PPIs (proton pump inhibitors), which are used to treat various gastrointestinal disorders such as acid reflux and ulcers. These medications have been shown to decrease the absorption of B12 from food, leading to lower levels of B12 in the body over time.
Metformin, a medication used to treat type 2 diabetes, is another medication that has been linked to lower B12 levels. Studies have shown that the use of metformin can interfere with the absorption of B12 in the body, leading to reduced levels of the vitamin.
Other medications that can potentially lower B12 levels include H2 blockers (used to treat acid reflux and ulcers), as well as certain antibiotics and anticonvulsants. The mechanism by which these medications lower B12 levels is not entirely clear, but it is thought to be related to interference with the absorption or transport of the vitamin.
It is important to note that while these medications can potentially lower B12 levels, not everyone who takes these medications will experience a deficiency. Factors such as diet, age, and other underlying medical conditions can also play a role in B12 levels. Anyone who is concerned about their B12 levels or who is taking medications that may lower B12 should talk to their doctor about monitoring their B12 status and potentially supplementing with B12 if necessary.
