How Much CBD Oil To Take For High Blood Pressure

High blood pressure affects the lives of millions of Americans. CBD oil may be able to help reduce blood pressure and foster a healthier lifestyle. Trying to figure out how much CBD oil to take to lower your blood pressure, how much it will drop, and how long it wil last? Here’s an informative guide.

High Blood Pressure and CBD Oil: Managing Hypertension

CBD oil is making waves in the medical world due to its wide range of potential health benefits, including its ability to help with high blood pressure.

High blood pressure, or hypertension, is usually caused by a combination of lifestyle and genetic factors, and generally worsens with increasing age. If not managed properly, high blood pressure is usually caused by a combination of lifestyle and genetic factors, and generally worsens with increasing age.

Below, you’ll find information on how CBD oil can help reduce hypertension and the research that’s been done on the topic, as well as recommended CBD dosage and delivery methods for lowering blood pressure. Please note that hypertension is a serious disease. If you decide to use CBD oil in the management of your high blood pressure, you should always do so in conjunction with your regular doctor.

Effectiveness of Using CBD Oil to Lower Blood Pressure

Used in Eastern countries for centuries, the cannabis plant is well known for its disease-fighting properties and health benefits. It contains over 100 plant compounds known as phyto cannabinoids, which act upon our body’s endocannabinoid system . The phytocannabinoids we know the most about are THC and CBD , both of which have antioxidative and anti-inflammatory properties.

There are a number of studies available that indicate CBD oil can lower blood pressure; this is why CBD oil carries the caution that it may not be suitable for pre- or post-operative patients. But, if you are suffering from hypertension, this could make CBD oil your saving grace.

One of the ways CBD oil reduces high blood pressure is by widening, or dilating, blood vessels. A 2017 study by the University of Nottingham found that just a single dose of CBD oil significantly lowered blood pressure in test subjects under stress and at rest.

Also in 2017, there was an i n-depth review of 25 previous studies that examined the use of CBD oil on hemodynamics (the dynamics of blood flow). The review concluded that while “Data from human studies investigating the effects of CBD on hemodynamics is still very limited … CBD may be used as a treatment for various cardiovascular disorders, such as hypertension, myocardial infarction, and stroke.” On the flip side, the study found that CBD mainly reduces BP and HR under stress conditions:

From the limited data available, we conclude that acute and chronic administration of CBD had no effect on BP or HR under control conditions, but reduces BP and HR in stressful conditions, and increases cerebral blood flow (CBF) in mouse models of stroke.

Finally, if your high blood pressure is due to high stress levels, CBD oil may be of good use to you. Cortisol, known as the “stress hormone,” is released by your body in times of stress. Between work, family, self-care, finances, and a mountain of other concerns, stress can become a constant in everyday life. This means your cortisol levels could be elevated, causing a physical stress response in your body that could be raising your blood pressure. In a 1993 study , CBD effectively lowered cortisol levels in test subjects, and lower cortisol levels lead to decreased blood pressure.

As more clinical trials and observational studies are conducted, CBD oil’s effectiveness in treating high blood pressure will become clearer.

Benefits of Using CBD Oil for Hypertension

High blood pressure can be brought on by a variety of factors, from diets high in salt and fat to stress to family genetics. High blood pressure damages artery walls, which can cause arteriosclerosis (where cholesterol plaques form). These plaques narrow the vessels and interfere with blood flow. When the plaques rupture, they can occlude the arteries completely, stopping blood flow and oxygen delivery to vital organs, which can be fatal.

While CBD oil has many well-documented benefits , there are other supplemental changes you can make to your lifestyle that may significantly reduce hypertension, like:

  • Adopting a healthy diet focussing on vegetables, fruits, nuts, meat, and fish, while avoiding processed foods and sugar.
  • Exercising regularly to strengthen your heart (this could be something as simple as taking a 30-minute walk each day).
  • Finding ways to manage stress, which could include seeing a therapist, meditating, journaling, or making art.

If you have high blood pressure, you may be taking one of the following medications:

  • Angiotensin II receptor blockers (ARBs) like Diovan which dilate blood vessels but can have side effects like:
    • Headaches.
    • Diarrhea.
    • Nausea.
    • Flu-like symptoms.
    • Back and joint pain.
    • Skin rash.
    • Diarrhea.
    • Constipation.
    • Vomiting.
    • Fatigue.
    • Insomnia.
    • Depression and anxiety.
    • Shortness of breath.
    • Decreased libido and other sex-related issues.
    • Dizziness.
    • Headaches.
    • Diarrhea.
    • Dry cough.
    • Skin rash.

    While effective in treating the symptoms of hypertension, the possible side effects these medications carry can make lowering your blood pressure an unpleasant experience. Cannabidiol (CBD), on the other hand, has little to no known side effects, and is “generally well tolerated with a good safety profile,” according to the World Health Organization .

    Cannabidiol is a cannabinoid derived from the cannabis plant, as is tetrahydrocannabinol (THC). While CBD and THC share some similarities, there are also key differences between the two. One of the biggest misconceptions about CBD oil is that it will get you high, when in reality CBD has none of the intoxicating, mind-altering properties associated with THC and marijuana consumption. In short, taking CBD oil will not get you high , making it a practical and popular choice for individuals who want to manage their high blood pressure with a more natural treatment option.

    However, because cannabidiol oil can react to certain medications (e.g. antidepressants and antibiotics), always talk to your doctor before testing out CBD oil as a potential treatment for hypertension.

    How to Use CBD Oil for High Blood Pressure

    Before you start experimenting with different CBD products and dosages, it’s imperative you speak to your doctor about using CBD oil for treating high blood pressure. If you’re still looking for more information on CBD as a medical supplement, you might also consider speaking with a cannabis doctor who specializes in the subject.

    When you have the all-clear from your physician you’ll need to decide how you’d like to take CBD oil. There are many different ways to consume CBD oil and the delivery format you choose will depend on your personal preferences and your lifestyle. Here’s a look at some of the most popular formats, their benefits, and their drawbacks:

    CBD Oil Capsules and Edibles

    Capsules and edibles are an easy and convenient way to take CBD oil, especially for beginners.

    • Benefits: The major benefit for this format is that the dose is consistent each and every time. There is no guesswork. And to this end, capsules and edibles are easy to work into your routine. Simply swallow a capsule or eat a gummy as directed, and you’re set! The effects can last a while, between 6-12 hours so you will likely not need to take another dose during the day.
    • Drawbacks: Eating CBD oil can delay its effects. When you swallow a capsule or consume an edible, the CBD oil has to pass through your digestive system before it is absorbed into the bloodstream. Depending on how fast your metabolism is, and the amount of food already in your stomach, the effects of the CBD oil could take between 20 minutes and an hour to appear. This is not the best method if you are looking for fast and immediate relief.

    CBD Oil Tinctures or Drops

    Tinctures and drops are a valuable option for people seeking quick results and maximum dosage control.

    • Benefits: Tinctures and drops are administered orally under the tongue. The CBD is absorbed directly into the bloodstream, allowing for results 30-60 minutes after use and the effects can last between 4 and 6 hours. CBD oil tinctures and drops are also convenient in that they store and travel well, and can be easily administered when needed.
    • Drawbacks: One of the biggest drawbacks to CBD oil tinctures and drops is the taste. Not everyone likes the natural, earthy, at times bitter flavor of hemp. Some products are flavored to compensate for this but then you need to consider where the flavoring comes from. Is it artificial flavor? Are they adding sugar and chemicals you’d otherwise want to avoid? Choice here comes down to preference, but it is worth consideration.

    CBD Oil Vapes

    CBD oil vapes are one of the fastest ways to get CBD into your system.

    • Benefits: When vaping CBD oil, it enters the bloodstream through the lungs, bypassing the digestive system. Effects can be felt in a matter of minutes. This is the best way to get a dose of CBD oil whenever you need it.
    • Drawbacks: The primary drawback to vaping CBD oil is that its effects do not last particularly long. Typically you can expect it to last 30 minutes to an hour or two. The problem with hypertension is that unlike anxiety, you can’t feel that your BP is up and that you need another dose. You’d have to keep on taking your BP during the day, so vaping CBD could be a little impractical.
    • Another potential issue with vaping is that it is hard to know exactly how much CBD is in each draw. CBD oil vape products come with a listed amount per inhale, but not everyone’s inhale will be the same so it requires a little bit of experimentation at first to get it right.

    CBD Oil Dosage for Hypertension

    Unfortunately, CBD oil does not come with a one size fits all dose. The amount you require will depend on your genetics, metabolism, size and weight. It is important to read the dosing instructions on any product you choose and start slowly.

    If you need further guidance, we at CBD Oil Review have tested hundreds of products and come up with the following dosage recommendation:

    The CBD Oil Review Serving Standard is 25 mg of CBD taken twice daily.*

    If this does not produce the results you are after, increase your dose by 25mg every 3-4 weeks until you find the relief you are looking for. For more information on CBD oil dosing, read our guide here .

    *FYI, our medical editors want you to know that the studies mentioned in this article were done with 300-600mg doses, which is considerably higher than our Standard. As we always say, when in doubt about taking CBD oil for anything, ask your physician!

    How Much CBD Oil To Take To Lower Blood Pressure

    Anecdotal reports claim that CBD oil can lower blood pressure.

    Early clinical research reports similar findings, which is great for anyone suffering from hypertension. But one question remains — how much do you need to take to get the effect?

    Available human studies used very large doses (600 mg) of pure CBD. Thankfully, you don’t need to take that much to get a benefit, especially if you’re using a full-spectrum product.

    Read on to learn how much CBD oil you should take to lower your blood pressure, the research evidence, and other tips.

    CBD and Blood Pressure: The Research

    Two recent studies found that CBD can lower blood pressure in healthy men.

    In the first 2017 study, nine men were given placebo or CBD capsules (600 mg) at rest and during three types of stressful situations: a mental stress test, exercise, and exposure to cold temperatures.

    Whereas the placebo capsules had no effect, the CBD treatment lowered resting systolic blood pressure by 6 mmHg. CBD also reduced the rise in blood pressure during stressful situations by 5 mmHg to 6 mmHg (1).

    The same researchers expanded on their findings in a 2020 study where they gave the same dose to 26 men every day for a week. The results were similar: CBD lowered mean arterial blood pressure and lowered the rise in blood pressure caused by exercising (2).

    Factors That Influence Your CBD Oil Dosage

    Early research suggests that CBD can lower blood pressure. However, 600 mg is a huge dose that’s not only hard to take but would also be quite expensive.

    Thankfully, such a large amount of CBD is not necessary for most people to lower their blood pressure. There are three main reasons why.

    First off, the studies used pure CBD (isolate). It’s not as effective as full-spectrum CBD, an extract that contains the full range of cannabinoids, terpenes, and other beneficial compounds naturally found in the hemp plant.

    Research has shown that all of the components of hemp and cannabis work in synergy, enhancing the effects of CBD and other cannabinoids (3). This is known as the cannabis entourage effect, and you can benefit from it by using full-spectrum CBD products instead of those containing just CBD.

    Secondly, capsules and other oral CBD products have notoriously low absorption, which means sublingual (under-the-tongue) CBD oil will require smaller doses to achieve a similar effect (4).

    Finally, everyone’s body responds to CBD differently. Your body weight, genetics, tolerance to cannabinoids, and even the product you’re using can all influence your CBD dosage.

    That’s why one person can experience a significant drop in blood pressure by taking 30 mg of CBD oil, while someone else might have zero effect from the same dose.

    So, how much CBD should you take?

    Ideal CBD Oil Dosage for Lowering Blood Pressure

    The best way to find the ideal dosage of CBD oil for lowering blood pressure is to follow the “start low and go slow” approach recommended by health experts (5).

    A good starting point is 10-15 mg of CBD oil. Pay attention to how you feel over the next two hours. Ideally, you’d want to use a blood pressure monitor to get an exact reading. However, you may be able to tell that your blood pressure dropped just from how you feel.

    After this, slowly raise the dosage over time and monitor your blood pressure again. Use this method to find the CBD dose that lowers your blood pressure by the desired amount.

    As a general guideline, most people find that doses of 20-100 mg doses of full-spectrum CBD oil are enough.

    Tips For Choosing the Ideal CBD Product

    If you’re trying out CBD oil to lower your blood pressure, we highly recommend choosing a full-spectrum product. As we mentioned earlier, full-spectrum CBD is more potent than pure CBD isolate.

    While you can also take CBD capsules or gummies, they won’t be as effective because CBD has low oral bioavailability (4). It’s ideal to stick to CBD oil, which has better absorption and works faster.

    You can also vape CBD, which has the advantage of working right away. However, there are some risks associated with vaping and its effects last shorter than other methods.

    How Fast Does CBD Oil Lower Blood Pressure?

    When you take CBD oil sublingually (under the tongue), it takes about 10–30 minutes to absorb and start working. Have your blood pressure monitor ready if you want to get an exact reading.

    Most people will notice subtle effects when the CBD starts to work, such as feeling more calm or relaxed.

    Meanwhile, if you vape CBD, you can feel its effects almost instantly.

    How Does CBD Oil Reduce Blood Pressure?

    There isn’t enough research to say for certain, but scientists theorize that CBD may inhibit the sympathetic nervous system (SNS), preventing an increase in blood pressure (1).

    Another possibility is that CBD affects the vagus nerve, which controls your blood pressure, heart rate, and other bodily functions.

    A third explanation is that CBD’s effects on blood pressure are secondary to its anxiety and stress-lowering effects. This isn’t surprising because both anxiety and stress can contribute to high blood pressure.

    General Tips for Shopping for CBD

    Whether you’re buying a CBD product for high blood pressure or any other health condition, it’s necessary to do some research beforehand.

    That’s because the CBD market is full of low-quality products that contain too little CBD or might be contaminated with pesticides, heavy metals, and other harmful substances.

    Here are the top three considerations to keep in mind to help you make an informed choice.

    Look for Third-Party Tested Brands

    Third-party tests are done by an independent laboratory and check whether a CBD product contains as much CBD as the company claims it does. These tests can also check for the presence of pesticides, heavy metals, and other contaminants.

    These tests are the best way to confirm that the CBD oil product you’re buying is both safe and effective.

    We highly recommend buying only from companies that provide these tests on their website. It’s even better if you take a glance at the tests yourself to confirm that the product in question contains the right amount of CBD.

    Check the Hemp Source

    CBD is extracted from hemp plants, which means how and where this hemp is grown will also have an impact on CBD oil quality.

    High-quality products are made from organic hemp cultivated in Colorado, Kentucky, or Oregon. Alternatively, European countries are also a great source of hemp.

    You should only buy from companies that clearly explain on their website where the hemp comes from. It’s even better if this hemp is USDA-certified organic, although this is still difficult to find due to regulations.

    Research the Company

    Reputable CBD brands will have many positive customer reviews on their website.

    They will also provide clear information about their manufacturing process, make it easy to access third-party lab reports, and may provide other helpful details like when the company was founded and by who.
