People use vitamin B for its ability to reduce stress, fatigue, and weakness. It’s also used as a cognitive enhancer. This vitamin also helps with DNA repair and cell production in the body. Vitamin B also plays an important role in keeping your skin, hair, eyes, and nervous system healthy. A deficiency of this essential vitamin may lead to conditions like beriberi or pellagra. While you can get enough vitamin B from foods like chicken liver, eggs, fish, soybeans, sunflower seeds, and split peas; some people require supplementation for optimal results. How long does vitamin B stay in your system after taking it?
How Long Does Vitamin B Stay In Your System?
1) Vitamin B12 (sometimes called cobalamin) is a water-soluble vitamin that’s usually found in food and taken as a supplement. Its other names include cobalamine and cyanocobalamin.
2) Vitamin B12 has many important functions in the body. It’s an important antioxidant; it helps with DNA repair and cell production; it maintains healthy nerves, muscles, immune system, and nervous system; and it helps your body produce red blood cells.
3) Vitamin B12 is made by bacteria in your gut or through the recycling of foods high in animal protein, like meat, fish, eggs and cheese. To get enough vitamin B12 from food sources alone, you need to eat foods that are fortified with this vitamin. Examples of these include certain cereals (such as Cheerios), soy milk for those who don’t eat dairy products (soymilk), beef liver capsules for vegans (liver health pills), nutritional yeast flakes for those who do not have a problem digesting dairy products (non-dairy fermented product), and fortified breakfast cereal products such as Shreddies on the health food store shelf. However, some people may also require vitamin B12 supplementation from supplements or medicines because they may not consume enough vitamin B12 from their diet alone or may be vegan or vegetarian since dairy products contain high levels of this nutrient. See our article on Vitamin D vs Vitamin D Supplementation for further information about which vitamins and minerals you need in your diet, and how much of them.
4) It’s important to note that supplements are not as efficient at providing vitamin B12 as food sources, which is why we recommend vitamin B12 from food sources first when you’re trying to get enough of this nutrient in your body, and why our product is a good choice for those who are vegan or vegetarian. See our article on Vitamin D vs Vitamin D Supplementation for more information about the dietary sources of vitamin B12, including foods like whole eggs (but not only), raw dairy products (in trace amounts), sushi, nutritional yeast flakes, and beef liver pills. We hope you find value in learning all you can about vitamins and minerals! Next month we’ll be going over some of the other essential nutrients you might want to know more about such as vitamin K2: MK-7.
What’s The Recommended Dosage Of Vitamin B?
1) For adults over the age of 50, the recommended daily intake (RDI) of vitamin B is 2.4 mcg/day. The RDI for children ages 1-3 years is 2.5 mcg/day; for children ages 4-8 years is 3 mcg/day; and for children ages 9-13 years it’s 3.4 mcg/day.
2) Most people don’t need to take a vitamin B supplement and can get all the vitamin B they need from their diet or from food sources that are fortified with this nutrient, such as fortified cereals and nutritional yeast flakes (a popular vegan product).
3) Some people may also require vitamin B12 supplementation from supplements or medicines because they may not consume enough vitamin B12 from their diet alone or may be vegan or vegetarian since dairy products contain high levels of this nutrient. See our article on Vitamin D vs Vitamin D Supplementation for further information about which vitamins and minerals you need in your diet, and how much of them.

How Long Does Vitamin B Stay In Your System?
1) Vitamin B is stored in the liver.
2) Vitamin B is hydrolyzed in the small intestine to release the active form of this nutrient called 5-methyltetrahydrofolate (5-MTHF). 5-MTHF is then converted to formaldehyde and then methylcobalamin, which are both active forms of vitamin B12.
3) Methylcobalamin cannot be used by the body without being converted to 5-MTHF first.
4) When food is consumed, a portion of it is digested and absorbed into the body, and a portion passes through the digestive tract undigested and excreted in feces. This undigested portion has no effect on vitamin B status because it’s not absorbed into the bloodstream.
5) The amount of methylcobalamin that can be absorbed depends on a variety of factors including: age, gender, race, genetics, health status (e.g., malabsorption), gut health (e.g., leaky gut or high intestinal permeability), stress levels (e.g., chronic stress), etc.
6) As with all nutrients that are absorbed by the body there will always be some level of variability between individuals when it comes to how efficiently they absorb vitamins and minerals such as vitamin B12 from food sources such as whole foods or food supplements like multivitamins or certain supplements containing multiple vitamins and minerals such as vegan multivitamins.
7) Vitamin B12 is not stored in the body in significant concentrations, so once it is absorbed it will be completely used up within a matter of hours.
Which Foods Contain Vitamin B?
1) Most vitamin B12 foods come from animal products such as eggs, dairy products, and seafood.
2) Vitamin B12 is not found in plant foods such as most fruits and vegetables.
3) There are a few plant-based sources of vitamin B12, but they are not recommended at this time because they have not been thoroughly researched to ensure that they contain sufficient amounts of vitamin B12 to be considered effective sources of this nutrient.
4) The best sources of vitamin B12 for vegans are supplements containing methylcobalamin (as opposed to 5-MTHF).
5) Some vegan multivitamins contain 5-MTHF instead of methylcobalamin. However, it’s generally believed that supplements containing 5-MTHF do not provide adequate amounts of active form of this nutrient so the recommendation is to take vegan multivitamin supplements that contain only methylcobalamin.
6) Vitamin B12 is found in animal products and plant foods. However, the best sources of vitamin B12 for vegans are supplements containing methylcobalamin (as opposed to 5-MTHF).
When Does Vitamin B Show Up On A Drug Test?
1) Vitamin B12 is not found in many foods, so it’s very unlikely that you’ll ever come into contact with it in your diet.
2) The only way to be exposed to vitamin B12 is through a drug test.
3) Many drug tests can detect vitamin B12, including: urine tests, hair tests, oral fluid tests, and blood tests (blood work).
4) The amount of vitamin B12 that is detectable in a drug test depends on the specific drug test being used.
5) For example, a hair test will not detect any amount of vitamin B12 because it detects proteins that are similar to the proteins produced by the body as part of normal detoxification processes.
6) However, a urine test will detect significant amounts of active form of this nutrient since the urine contains waste products from the body and these include forms of vitamin B12 which are normally produced by the body in order to detoxify various drugs and toxins from our systems (e.g., alcohol).
7) The amount of vitamin B12 that is present in the urine of an individual will depend on the amount of alcohol consumed and the amount of vitamin B12 that is stored in the liver.
8) The presence of this nutrient in a urine test will not indicate whether a person has been abusing drugs or not, but it may indicate that they have abused drugs.
9) A hair test also detects proteins which are similar to those produced by the body as part of normal detoxification processes.
10) Therefore, a hair test will not detect any amount of vitamin B12 since it detects proteins that are similar to those produced by the body as part of normal detoxification processes.
Conclusion
The above information shows that vitamin B stays in your system for a short time. While a urine test is unlikely to detect vitamin B, a blood test is more sensitive. Vitamin B stays in your blood for three days, and in your urine for three days as well. If you’re taking vitamin B in the form of a supplement, it’ll show up in your urine for about three days. If you’re taking vitamin B in the form of a suppository, it would take a week for the drug to show up in the urine.
