Can you overdose on vitamin B12? Overdosing on vitamin B12 is unlikely. Because vitamin B12 (cobalamin) is a water-soluble vitamin and your body excretes it daily in your urine, it doesn't build up in the body like fat-soluble vitamins—like vitamin D—do.
Vitamin B12 has a low risk of causing harm, even at high doses. Because of this, there's currently no maximum dose that's widely recommended.
Water soluble vitamins, like B12, can be tolerated at higher doses without adverse effects upon the body, and the National Academy of Medicine has not established an upper limit of Vitamin B12 intake.
Even the lowest doses in B12 supplements are many times the recommended dietary allowance. Doses up to 1,000 mcg, though unnecessary, aren't harmful.
You can swallow a pill or take a tablet that melts under your tongue. The doctor may start you out at 1,000-2,000 micrograms a day. Once your levels are normal, you may need 100-500 micrograms a day or 1,000 micrograms one or two times a week.
Vitamin B12 is a nutrient that helps keep your body's blood and nerve cells healthy and helps make DNA, the genetic material in all of your cells. Vitamin B12 also helps prevent megaloblastic anemia, a blood condition that makes people tired and weak.
Vitamin B12 is an essential nutrient. Fish, shellfish, meat, eggs, and dairy products are good sources of vitamin B12. The amount that should be consumed on a daily basis is called the recommended dietary allowance (RDA). The RDA is 2.4 mcg daily for people 18 years and older.
Once you begin treating your vitamin B12 deficiency, it can take up to six to 12 months to fully recover. It is also common to not experience any improvement during the first few months of treatment. If you can, it's a good idea to address what's causing the deficiency.
Interactions between your drugs. No interactions were found between Vitamin B12 and Vitamin D3. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.
Disturbed or blurred vision can also occur as a result of a Vitamin B12 deficiency. This happens when the deficiency causes damage to the optic nerve that leads to your eyes. The nervous signal that travels from the eye to the brain is disturbed due to this damage, leading to impaired vision.
Vitamin B12 deficiency can have distressing neuropsychiatric symptoms. It can have an etiological role in clinical presentations like depression, anxiety, psychosis, dementia, and delirium, requiring screening of at-risk populations.
A serum B12 above 300 pg/mL is interpreted as normal. Patients with B12 levels between 200 and 300 pg/mL are considered borderline, and further enzymatic testing may be helpful in diagnosis. Patients with B12 levels below 200 pg/mL are considered deficient.
Foods high in vitamin B12
Vitamin B12 deficiency can cause anemia which is one of the most common causes of low blood pressure. Adding more vitamin B 12 can help you fight several health issues as well as low blood pressure.
Using high doses of vitamin B12 (cyanocobalamin) to treat anemia can lead to low levels of potassium and/or high platelet counts in the blood. Severely low potassium levels can cause life-threatening heart problems, and high platelet counts can lead to issues with too much blood clotting.
Vitamin B12
According to health experts at Click Pharmacy, as a general rule of thumb, take your B vitamins in the morning or with a meal. Vitamin B12, for example, should definitely be taken in the morning. This is because it is important for energy metabolism, which may interrupt your sleep if taken at night.
If you have any of the following health problems, consult your doctor or pharmacist before using this medication: a certain eye disease (Leber's optic neuropathy), a certain blood disorder (polycythemia vera), gout, iron or folic acid deficiency anemia, low potassium blood levels (hypokalemia).
Fatigue. Megaloblastic anemia due to vitamin B-12 deficiency may lead to a person feeling fatigued. Without enough red blood cells to carry oxygen around their body, a person can feel extremely tired.
Diet. Some people can develop a vitamin B12 deficiency as a result of not getting enough vitamin B12 from their diet. A diet that includes meat, fish and dairy products usually provides enough vitamin B12, but people who do not regularly eat these foods can become deficient.
Apples Aside from being an important inclusion in a list of vitamin B12 fruits, apples are also rich in fibre, antioxidants, and flavonoids. Apples also comprise polyphenols that are found in both the peel and the pulp of the nutrient-dense fruit.
Vitamin B12 is considered an important brain and nervous system micronutrient and is often used for anxiety. It helps to ensure normal function for your nerves, which can help combat physical symptoms of anxiety.
