Can I Take Vitamin B12 With High Blood Pressure?

Vitamin B12 is a water-soluble vitamin that helps keep the body’s nerve and blood cells healthy. It also helps make DNA, the genetic material in all cells. Vitamin B12 can be found naturally in animal products such as fish, meat, poultry, eggs, milk and milk products. For those who don’t eat enough of these foods or follow vegan diets they may need to take supplements to ensure adequate intake of this important nutrient.

For people with high blood pressure (hypertension) taking supplemental vitamin B12 is generally considered safe; however it’s always best to consult with your doctor before taking any supplement or making changes to your diet as there could be potential interactions with other medications you are already on.

There are several different forms of Vitamin B12 available including tablets/capsules, sublingual tablets/lozenges which dissolve under the tongue, oral sprays and injections administered by a healthcare professional if needed. The most common form used for supplementation is cyanocobalamin – an artificially produced form which has been shown to raise serum levels more effectively than its natural counterpart methylcobalamin which is found in food sources such as seaweed and tempeh. Cyanocobalamin needs no further processing by the body so it is often recommended for those with absorption issues or pernicious anaemia where less than half of ingested vitamins can be absorbed due to inadequate stomach acid production caused by age or autoimmune disease like Graves’ Disease or Crohn’s Disease.

Vitamin B12 also plays an important role in maintaining energy levels throughout the day as it helps convert carbohydrates into glucose – fuel for our bodies. As well as supporting red blood cell formation it can help reduce symptoms associated with depression & anxiety while aiding cognitive function & memory retention – key components when studying & exams come around! But certainly not least we cannot forget how essential this vital nutrient is when forming new cells so incorporating into your daily routine should become part of a regular maintenance program if you want optimal health & wellbeing.

Overview of Vitamin B12

Vitamin B12, also known as cobalamin, is a water-soluble vitamin found naturally in some foods. It helps to produce red blood cells and keep the nervous system healthy. It can be taken as a supplement or injected for people with certain health conditions that make it difficult to absorb enough of the vitamin through their diet alone.

The recommended daily intake (RDI) of Vitamin B12 is 2.4 micrograms per day for adults over 19 years old. However, this amount may vary depending on age and other factors such as pregnancy or breastfeeding status. For those taking medication that affects absorption, they may need more than the RDI suggests.

Vitamin B12 deficiency can cause anemia, fatigue, poor memory and concentration problems, vision loss and depression if left untreated. Symptoms usually develop slowly over time and can be mild at first but worsen without treatment. Taking supplements of Vitamin B12 is one way to prevent deficiency and replenish stores in people who are already deficient due to medical conditions or dietary restrictions.

Relationship to High Blood Pressure

Vitamin B12 is an essential vitamin for the human body, but it has not been widely studied in relation to high blood pressure. While it can be taken with medications for hypertension, research suggests that Vitamin B12 may have a unique relationship to this condition.

Recent studies show that people with higher levels of Vitamin B12 tend to have lower rates of high blood pressure compared to those who are deficient in the vitamin. This could indicate that maintaining adequate levels of Vitamin B12 might help reduce the risk of developing hypertension or lessen its severity if already present.

Though further research is needed, evidence so far suggests there may be a link between optimal levels of Vitamin B12 and healthy blood pressure readings. For individuals with hypertension, supplementing their diet with foods rich in this nutrient could be beneficial as part of a larger health plan involving other lifestyle changes and medications prescribed by their healthcare provider.

Potential Benefits of Supplementation

Vitamin B12 is an essential nutrient, and its supplementation may offer a number of potential benefits for those with high blood pressure. This vitamin plays an important role in the functioning of your brain, nervous system and metabolism. It helps to create red blood cells that transport oxygen around the body, as well as supporting a healthy immune system.

In terms of cardiovascular health, research has suggested that taking B12 supplements can help reduce homocysteine levels in people with hypertension. Homocysteine is an amino acid which increases risk for heart attack or stroke if present at higher levels than normal in the bloodstream. Vitamin B12 can help keep this level within a healthy range by breaking down the homocysteine into harmless molecules such as cystathionine and methionine.

Studies have also indicated that supplementing with vitamin B12 might be able to lower systolic blood pressure (the top number) by up to 10 mmHg after 8 weeks of use when compared to placebo groups who did not take any supplements during this time frame. Further research suggests that combining B12 supplementation with other vitamins such as folate may produce even greater results on reducing high blood pressure numbers over time.

Possible Risks Involved

Vitamin B12 is a nutrient that has been shown to have many health benefits, however it is important to be aware of the potential risks associated with taking this vitamin if you are already taking medication for high blood pressure. While there are some studies which suggest that Vitamin B12 may help reduce blood pressure levels, these results have not yet been conclusively proven. Therefore, it is best to err on the side of caution and talk to your doctor before starting any supplement regimen involving Vitamin B12 if you have high blood pressure.

It should also be noted that people who take diuretics or “water pills” as part of their treatment plan for high blood pressure can actually increase their risk of Vitamin B12 deficiency due to increased urination caused by these medications. If you take diuretics for your hypertension, then it may be beneficial to discuss supplementation with your healthcare provider in order to prevent potential deficiencies from occurring.

Individuals who suffer from certain conditions such as pernicious anemia or gastrointestinal disorders like celiac disease or Crohn’s Disease may require higher doses of Vitamin B12 in order to maintain adequate levels in the body and therefore need special consideration when considering adding this vitamin into their diet while they are managing hypertension. It is always best practice to check with a qualified medical professional before making any changes related to dietary supplements when suffering from a pre-existing condition like high blood pressure.

Doctors’ Recommendations

When it comes to taking vitamin B12 with high blood pressure, doctors may recommend that people take this supplement with caution. This is because there are some potential risks associated with taking a large dose of the vitamin. Taking too much can cause an increase in blood pressure and other side effects. Therefore, it is important to speak with your doctor before starting any new supplements or increasing your current dosage.

Those who have been diagnosed with hypertension should monitor their intake of Vitamin B12 closely when they start taking a supplement as part of their treatment plan. High doses may cause an increase in heart rate and blood pressure, so if you experience these symptoms while taking the supplement it is best to stop using it and consult your physician right away. It’s also important for individuals on medications for high blood pressure to discuss all dietary changes including Vitamin B12 supplementation with their doctor first before making any major changes in order to avoid potential drug interactions or side effects from combining drugs and supplements.

Although studies suggest that Vitamin B12 may help reduce inflammation which could improve cardiovascular health, more research needs to be done in order for healthcare professionals to make definitive recommendations regarding its use for treating hypertension specifically. Speaking with your doctor about whether or not you should take Vitamin B12 if you have high blood pressure is always recommended as each individual case will vary depending on other factors such as age, weight and overall health status among others things.

Interactions with Medication

When it comes to managing high blood pressure, many people take prescription medications as a way of controlling their condition. When taking these medications, it is important to understand how other substances may interact with them. This includes vitamin B12, which can be taken in supplemental form or obtained through dietary sources such as fortified cereals and dairy products.

Interactions between vitamins and medications can vary depending on the type of medication being used to treat high blood pressure. For example, calcium channel blockers are commonly prescribed for this condition but they may interfere with the absorption of certain vitamins including B12 if taken at the same time. As such, people taking these drugs should consult their doctor before supplementing with additional B12 or making any major changes to their diet that could affect its intake level.

In some cases, doctors may recommend increasing one’s consumption of foods rich in vitamin B12 while avoiding supplements in order to reduce the risk of interactions with other medications being taken for hypertension control. Eating plenty of fruits and vegetables can also help ensure adequate levels of this essential nutrient while potentially reducing the risk associated with combining multiple drugs or supplements together when treating high blood pressure symptoms.


Vitamin B12 is a beneficial nutrient that has been found to have several health benefits. It can be taken in supplement form or obtained through food sources such as meat, fish, eggs and dairy products. While Vitamin B12 has many potential benefits, it is important to remember that it should not be taken if you have high blood pressure. If you do take vitamin B12 supplements, make sure to talk to your doctor about the right dosage for you and any possible side effects or interactions with other medications. Taking too much vitamin B12 may lead to an increase in blood pressure which could cause serious health problems. So while Vitamin B12 is generally safe and beneficial for most people, those with high blood pressure should consult their healthcare provider before taking any supplements of this essential nutrient.
