Early research indicates that CBD oil may help lower blood pressure, which is great for anyone suffering from hypertension. But one question remains — how much do you need to take get the effect?
The only research evidence we have used a large, 600 mg dose of pure CBD in capsule form.
In this 2017 study, healthy men were given placebo or CBD capsules 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.
These results are supported by many anecdotal reports of CBD users, who have noted both small and large drops in 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 dose may not be necessary for most people to lower their blood pressure.
Let’s explain why:
- Capsules and other oral CBD products have notoriously low absorption, which means regular CBD oil will require smaller doses to achieve a similar effect.
- The study used pure CBD isolate, which is less effective than full-spectrum CBD products containing the full range of cannabinoids, terpenes, and other beneficial hemp compounds.
- Everyone’s body is different and responds to CBD differently which means that a dose that works for one person is not necessarily ideal for someone else.
So, how much should you take?

Ideal CBD Dosage for Lowering Blood Pressure
The best way to figure out the ideal CBD dosage for lowering high blood pressure or any other health issue is to start low and go slow. This is especially true if you’re completely new to CBD.
If you’re using a CBD oil, start with the lower possible dose by placing one or a few drops under the tongue. Assess how you feel over the next 30 minutes.
If you don’t notice any changes in your blood pressure, gradually raise the dosage over time, ideally a drop at a time.
Use this method until you reach the CBD dose that lowers your blood pressure by the desired amount. Congratulations — you found the best CBD dosage that works for you!
The reason we recommend this method is because the ideal CBD dosage depends on many factors, including your body weight, genetic differences, tolerance to cannabinoids, and the type of product you’re using.
That’s why one person can experience a significant drop in blood pressure by taking 10 mg of CBD oil, while someone else might have zero effect from the same dose.
How Much Does CBD Oil Lower Blood Pressure?
The only study of CBD for lowering blood pressure reported a 5-6 mmHg reduction in systolic blood pressure when using CBD.
Meanwhile, online reports of CBD oil users have noted reductions ranging from only a few points to as much as -23 mmHg for systolic blood pressure and -12 for diastolic.
Also, keep in mind that for most people, the drop is the highest right after CBD starts to work (about 10-30 minutes after you take it), and then your blood pressure gradually returns to baseline over the next couple of hours.
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 for this time 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.
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).
Another possibility is that CBD affects the vagus nerve, which controls your blood pressure, heart rate, and other bodily functions.
A third possibility 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 elevated blood pressure.
Tips For Choosing the Ideal CBD Product To Lower Your Blood Pressure
If you’re trying out CBD oil to lower your blood pressure, we highly recommend choosing a full-spectrum CBD oil.
Full-spectrum CBD products benefit from what’s called the entourage effect — the synergy between cannabinoids, terpenes, and other beneficial compounds present in hemp. All of these components work together with CBD, enhancing its effectiveness.
Simply put, a full-spectrum hemp product will require smaller doses than one made with pure CBD (called CBD isolate).
Also, be aware that CBD’s potency depends on how you’re taking it. If you prefer to use CBD in capsule or gummy form, then you’ll need to take larger doses to get the same effect as a CBD oil. That’s because CBD is poorly absorbed when you ingest it.
As such, it’s ideal to stick to CBD oil, which has far better absorption and also tends to work faster.
General Tips for Shopping for CBD Oil Products
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 two considerations to keep in mind to help you make an educated 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 far and away 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 quick 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.
