The amount of time B vitamins remain in your system typically depends on the type of B vitamin and how much of it is taken. B Vitamin B12 may remain in your system for several days, however, the effect of B Vitamin supplementation may last in the body for several weeks or even months.
Vitamin B1 (thiamin) stays in the body for somewhat shorter periods of time than many other B vitamins, usually around 1-3 hours. Vitamin B6 (pyridoxine) is similarly eliminated from the body in a short time, around 4-5 hours.
Vitamin B9 (folate or folic acid) may stay in the body for up to 48 hours after ingestion. Vitamin B3 (niacin) is a water-soluble vitamin as well, and can remain in the body for up to 4 hours.

How long does it take for B12 to leave your system?
The time it takes for B12 to leave your system depends on several factors, including how much B12 was initially consumed, the individual’s biochemical makeup, other dietary influences, and the type of B12 consumed.
On average, most individuals with no B12 deficiency will retain B12 within their system for 1-3 days. If a deficiency is present, then B12 might take 6-7 days to leave the system. Some studies have suggested that B12 can remain in the body for over a month if an overdose.
Does your body get rid of excess vitamin B?
Yes, your body can get rid of excess vitamin B. Your body doesn’t need to store large amounts of water-soluble vitamins such as B vitamins. When you ingest more than your body needs, the extra is simply excreted in your urine.
Consumption of vitamin B supplements is not harmful, but it is important to note that excessive intakes can lead to adverse effects. Signs and symptoms may include nausea, stomach pain, loss of appetite, increased urination, tingling or numbness in the hands and feet, and changes in the way you process fats.
If you are taking a vitamin B supplement, it is important to check the label for the recommended daily allowance.
Does your body flush out extra B vitamins?
Yes, the body typically has a capacity to flush out excess B vitamins when they are not needed. B vitamins are water-soluble, meaning that they can be easily dissolved in water and easily excreted from the body through urine.
When people take a large amount of B vitamins in supplement form or in fortified foods, the body will absorb only what it needs and then excrete the rest. This is beneficial, especially for those who want to avoid any potential overconsumption of B vitamins.
For this reason, it is generally safe to take high doses of B vitamins without risk of toxicity. In some cases, people may experience side effects such as nausea and vomiting, but this is usually temporary and not dangerous.
It is important to keep in mind, however, that a balanced diet is the best way to ensure optimal levels of B vitamins in the body.
What happens if you have too vitamin B?
If you consume too much vitamin B, it can lead to a range of unwanted side effects. This can include heightened energy levels, increased urination, blurred vision, itching, skin rashes, and nausea. Excess vitamin B also increases the risk of nerve damage and heart problems, as well as an elevated level of homocysteine, which is linked to an increased risk of cardiovascular disease.
In some cases, too much B vitamins can also cause anemia. It’s important to be mindful of how much vitamin B you consume, as it is a water-soluble vitamin and any excess will not be stored in the body and will be flushed out through urine.
It’s best to talk to your healthcare provider to make sure you’re getting the right amount of B vitamins and ensure you don’t suffer any serious side effects.
Does vitamin B accumulate in the body?
Yes, some forms of vitamin B can accumulate in the body. While most water-soluble vitamins, including B vitamins, are easily absorbed and eliminated, some can stay in the body for a long period of time, allowing it to store small amounts of them for future use.
In particular, Vitamins B12 and B6 can build up in the liver, and Vitamin B12 can also be stored in the kidneys. However, it is important to note that most people do not need to worry about storing too much vitamin B12 since it is a very stable vitamin and is unlikely to reach dangerous levels.
The body only stores very small amounts and will naturally excrete any extra amounts not needed.
What can happen if your B12 level is too high?
If your B12 levels are too high, it is rarely a cause for concern as long-term serious health effects are not typically seen. High B12 levels can indicate certain medical conditions or lifestyle choices, such as being a regular consumer of dietary supplements.
Because B12 is a water-soluble vitamin, it is not stored in your body and the excess is eliminated through urine or in bile. Generally, the risks of a high B12 level are minimal, but some studies have found a relationship between a high level of B12 and cancer progression.
Additionally, high B12 levels can also mask a vitamin B9 (folate) deficiency, which can lead to deficiencies in other nutrients. If someone has an elevated B12 level, they should speak with a doctor to understand any potential underlying causes and ensure that any other deficiencies are addressed.
How to reduce B12 level?
Reducing B12 levels requires a few lifestyle changes and potentially some supplements. Eating a diet lower in animal products and processed foods and opting for more whole grains, non-meat proteins, fruits, and vegetables can significantly lower B12 levels.
Additionally, avoiding foods high in certain B-vitamins can also help reduce B12 levels. Additionally, incorporating various B12-blocking supplements, such as chlorella, spirulina, and certain herbs, can further help reduce B12 levels.
Lastly, limiting the intake of multivitamins which contain B12, as well as reducing the amount of alcohol consumption, can lower B12 levels.
How long does it take to get rid of vitamin B6 toxicity?
The duration of vitamin B6 toxicity depends on the amount and duration of the intake. Generally, it takes months to clear a toxic amount of vitamin B6 from the body. However, with high doses, the body may require more time to return to vitamin B6 homeostasis.
If the individual has been receiving high levels of vitamin B6 for prolonged periods, it may take as long as a year to return to a safe level. It is important to discontinue use of any vitamin B6 supplements and minimize foods that are high in vitamin B6.
Additionally, it is important to consume adequate amounts of fluids to flush the kidneys and liver of the extra vitamin B6. If an individual’s vitamin B6 levels remain elevated despite discontinuing supplementation and dietary changes, a doctor may prescribe an agent that helps to clear out the excess vitamin B6.
Can too much vitamin B make you feel weird?
Yes, it is possible to experience negative side effects from having too much vitamin B in your system. Vitamin B is water-soluble, meaning that it will not build up in the body and excess amounts must be excreted through urine.
When too much Vitamin B is consumed, it can cause symptoms such as headaches, tiredness, loss of appetite, vomiting and abdominal pain. It may also cause skin rashes, anemia, elevated heart rate, and decreased cognitive function.
Overdosing on Vitamin B can also cause fever, confusion, and seizures in some cases. It is important to note that vitamin B toxicity is very rare, but if too much is taken, it can be dangerous. Therefore, it is always best to be mindful of the amount of vitamin B being consumed and to speak with a healthcare professional before beginning a supplementation regimen.
How do B vitamins leave the body?
The body expels B vitamins from the body through a variety of pathways. When these vitamins are not actively being used in the body, they are released in the urine and feces. Most B vitamins are water-soluble, meaning that they are quickly absorbed by the body and released in the urine.
B vitamins that are not actively used by the body are generally stored in the liver and released as needed. Additionally, some of the B vitamins are fat-soluble, and are eliminated via bile produced in the gallbladder, which is transported to the small intestine and released in the feces.
In some cases when there is an excess of B vitamins in the body, it may be eliminated through the sweat, in the breath, and in breast milk. Ultimately the body’s main goal is to maintain a healthy balance and in order to do this, it will excrete vitamins when it is necessary.
How is B12 removed from the body?
The body naturally removes vitamin B12 from the bloodstream through a process called enterohepatic circulation. As blood passes through the liver, the organ removes the vitamin for reuse. Kidneys also play a role in this process, as they can filter out incoming B12 from the food that’s eaten.
Any excess that the body doesn’t need is expelled from the body through urine. Additional B12 may also be dispensed via sweat if the body is exposed to high temperatures.
How do I know if I’m taking too much vitamin B12?
It is important to speak with your doctor or health care provider before taking any dietary supplement, including vitamin B12. They will be able to give you personalized advice about how much of the supplement you should be taking, based on your overall health and dietary needs.
Taking too much vitamin B12 can be dangerous. It is important to be aware of the signs of too much vitamin B12, which include feeling jittery or having a metallic taste in your mouth. Additionally, too much vitamin B12 can lead to symptoms such as nausea, stomach pain, loss of appetite, diarrhea, headaches, and dizziness.
You should also be aware of other health complications like liver or kidney damage, which can occur if you take too much vitamin B12. Additionally, if you take a supplement, it is important to monitor your levels of the vitamin, since excessive levels can indicate that you have taken too much.
Can too much b12 cause flushing?
It is possible for too much B12 to cause flushing, but it is unlikely. Flushing is a common reaction to taking high doses of vitamins and minerals, and B12 is no exception. However, it is important to note that flushing is usually caused by taking a single, large dose of B12 or a combination of supplements with B12, rather than moderate or low doses of B12 over the long term.
When taking B12, it is recommended to start with low doses and then increase to the optimal level, rather than taking a single large dose.
Since B12 is water-soluble, it is not possible to overdose on it so any excess will just be excreted in the urine. If you experience flushing while taking B12, it is advised to reduce the dose or if you prefer not to, to take it with food or spread it out over a few doses throughout the day.
It is also important to check with your doctor to make sure it is safe for you to take the B12, particularly if you have any pre-existing health conditions.
Can you take too much of any of the B vitamins?
Yes, it is possible to take too much of any of the B vitamins. Taking too much of one or more B vitamins can lead to a condition called hypervitaminosis B, which can have serious side effects depending on which B vitamin is over-consumed.
For example, consuming high doses of B6 can cause nerve damage, while taking large amounts of B1 (thiamine) can cause an irregular heartbeat. Even within the daily recommended limits for B vitamins, it is important to be aware that certain medications can interact with them, so it’s important to make sure you talk to your doctor before taking any type of supplement.
Additionally, because the B vitamins are water-soluble, they are excreted through urine and any excess amounts not used by the body will pass through the body. Therefore, it is generally not recommended that you take more than the daily recommended limit of B vitamins.
