Vitamin B12 is an essential nutrient that helps to produce red blood cells, maintain nerve tissue, and regulate energy levels. It’s found in animal-based foods such as meat, fish, poultry, eggs and dairy products. While most people can get enough vitamin B12 from their diet alone, some may need additional supplementation due to certain medical conditions or lifestyle choices.

For those who should not take Vitamin B12 supplements include: individuals with a rare genetic disorder called Imerslund-Gräsbeck syndrome; people with low stomach acid (hypochlorhydria); those taking proton pump inhibitors for gastroesophageal reflux disease (GERD) or other stomach ailments; vegans/vegetarians who do not consume animal sources of food; pregnant women at risk of deficiencies due to poor dietary intake; elderly individuals whose bodies are less efficient at absorbing the vitamin from food sources; and anyone with signs of a deficiency such as fatigue, weakness or difficulty concentrating.
The form of supplement used will vary depending on the person’s individual needs. Generally speaking though it comes in either pill form or injections administered by a healthcare professional. Pills come in various doses ranging from 50 mcg up to 1 mg per dose taken daily for several weeks until symptoms improve before stopping use altogether. Injections can be given intramuscularly if necessary but usually oral administration is preferred since it has fewer side effects than injections including pain around the injection site and potential skin discoloration where injected over time if used too often.
When considering Vitamin B12 supplements one must remember that everyone’s body is different and what works for one person might not work for another so consulting with your doctor prior to starting any type of supplementation regimen is important in order to ensure safety and effectiveness while also avoiding any adverse reactions which could occur if taken incorrectly or without proper guidance from a medical professional first hand.
Children
When it comes to children, vitamin B12 supplements are generally not recommended. The body’s ability to absorb this essential nutrient is typically developed in early childhood, and as such, most children do not need supplementation. The dosage of a supplement would be difficult to accurately calculate for an individual child based on their age and size. Consuming too much of certain vitamins can lead to health problems for young people. For example, ingesting excessive amounts of Vitamin B12 could lead to skin rashes or diarrhoea.
It is also important that parents pay close attention if they believe their child may have a deficiency in Vitamin B12 due to dietary restrictions or underlying medical conditions like Crohn’s disease or Coeliac disease. In these cases, consulting with a doctor regarding appropriate treatment options should be the first step before considering any supplementation plan for your child.
When taking into consideration dietary sources of Vitamin B12 it should be noted that animal-based products are the only reliable source for this vital nutrient; however vegan and vegetarian diets provide other healthy alternatives which should also be taken into account before making any decisions about supplementation in children.
Individuals with High B12 Levels
Vitamin B12 is an essential vitamin that plays a role in many bodily functions. It’s important for healthy blood cells and DNA, as well as nerve function. However, it can be dangerous if taken in too large of doses or by individuals who already have high levels of the nutrient. Individuals with naturally high levels of B12 should not take additional supplements to avoid toxicity.
Some conditions can cause higher than normal concentrations of B12 including liver disease, certain types of cancer, and overactive thyroids. Patients with any these conditions should speak to their doctor before taking additional vitamin b12 supplements to ensure safe intake amounts are determined based on their individual needs. Similarly, pregnant women should consult a medical professional before supplementing with vitamins as some nutrients may be contraindicated during this time period due to potential risks associated with excessive consumption during pregnancy.
In addition to existing health issues that may contribute to elevated b12 levels, dietary choices such as eating fortified foods like breakfast cereals and nutritional yeast can also lead to increased concentrations within the body and make it unnecessary for individuals who consume these items regularly take extra supplementation measures beyond what they’re already getting from their diets alone.
People with Leber’s Disease
People with Leber’s Disease should be especially careful when considering taking vitamin B12 supplements. This is because those with this inherited eye disorder can have a genetic defect that causes them to be unable to properly metabolize the nutrient, resulting in potentially dangerous buildup of it in their bodies. This can lead to severe health problems, including nerve damage and anemia. As such, people with Leber’s Disease should speak with their doctor before taking any kind of supplement containing vitamin B12 or its derivatives.
Even if someone without Leber’s Disease is considering taking a vitamin B12 supplement for other reasons (such as energy enhancement), they may still want to consider speaking with a physician first as well. While there are generally few risks associated with taking extra amounts of this essential nutrient, certain individuals may need additional monitoring depending on their particular medical situation and history – something only a healthcare professional can advise on adequately.
In addition to consulting one’s doctor prior to beginning any type of dietary supplementation regimen, people should also make sure they understand what exactly each pill contains in terms of vitamins and minerals; reading labels carefully is important here too since not all products will contain just pure vitamin B12 or its derivatives alone but rather combinations of various substances as well.
Those Taking Metformin
Metformin is a widely prescribed drug for type 2 diabetes, and those taking it should not take vitamin b12 supplements. Metformin interferes with the absorption of this nutrient, so additional supplementation can lead to dangerously high levels in the blood. Metformin works by decreasing the amount of glucose produced in the liver and increasing insulin sensitivity which helps control blood sugar levels; adding vitamin b12 can interfere with these effects.
For those who are on metformin, it’s important to get their B12 level tested regularly as part of routine health care screenings. If tests show that their B12 level is low, they may need an alternative form of supplementation such as a liquid or patch rather than tablets or capsules. Individuals should talk to their doctor about any other medications they are taking that could also be affecting their B12 absorption before starting any kind of supplement regimen.
Eating foods rich in B vitamins like fortified cereals and eggs may help some people meet their daily needs without having to take supplements at all – especially if dietary changes alone aren’t enough to bring one’s B12 levels up into normal range.
People With Vitamin Overload
When it comes to taking vitamin B12 supplements, those who already have an overload of the nutrient should take caution. Vitamin B12 is naturally found in animal products like meat and dairy, but can also be taken as a supplement. While this nutrient is essential for many body functions, including red blood cell production and nerve health, too much can lead to adverse effects on your health.
People with conditions that affect their ability to absorb vitamins from food or who are taking medications that interfere with the absorption of vitamin B12 may need extra supplementation. However, if you already have adequate levels of the vitamin in your system then taking additional doses could result in a condition known as hypervitaminosis – essentially having too much of this vital nutrient stored up in your body’s tissues.
Symptoms of hypervitaminosis include fatigue, headaches, nausea and even depression due to an imbalance between other nutrients such as calcium or magnesium. In extreme cases it can cause kidney damage or liver failure which require immediate medical attention. Therefore it’s important for anyone considering supplementing their diet with additional sources of vitamin B12 to first consult with their doctor and get tested for any existing deficiencies before starting any new regimen.
Those Taking Immunosuppressants
Immunosuppressants are powerful drugs used to prevent the body’s immune system from attacking itself. These drugs can be used to treat autoimmune diseases such as lupus, rheumatoid arthritis and multiple sclerosis. People who take immunosuppressant medications should avoid taking vitamin B12 supplements because it can interact with their treatment.
Taking vitamin B12 supplements while on immunosuppressive medications may reduce the effectiveness of the medication in managing symptoms or treating the underlying condition. This could potentially lead to further health complications for those affected by an autoimmune disorder that require treatment with immunosuppressants. High doses of Vitamin B12 have been associated with an increased risk of infection in people taking immuno-suppressive treatments, which can be dangerous if left untreated or unmanaged properly.
For those taking immuno-suppressive treatments, there is a need for careful monitoring of any potential interactions between vitamin B12 supplementation and other medication they might be prescribed. It is best practice to consult with a doctor before beginning any new supplement regimen while on these types of medications so that potential adverse reactions are avoided and monitored closely.
Pregnant Women
Pregnant women should avoid taking vitamin B12 supplements unless they are recommended to do so by a medical professional. This is because the body needs more nutrients during pregnancy, and these additional nutrients can come from food sources instead of supplements. High doses of vitamins can be harmful for both mother and baby. Taking too much Vitamin B12 could cause the baby to become malnourished or even suffer birth defects.
Another reason why pregnant women should not take Vitamin B12 supplements is that it may interfere with other medications they may be taking during their pregnancy such as prenatal vitamins or iron supplements. There have been reports that excessive amounts of Vitamin B12 have caused nausea and vomiting in some pregnant women which can further complicate matters during this already delicate period of time in a woman’s life.
If a pregnant woman does feel like she needs an extra boost in her Vitamin B12 levels then she should discuss this with her doctor first who will be able to recommend alternative solutions such as dietary changes or other forms of supplementation before resorting to taking higher doses than necessary via supplement form.
