CBD & Low Blood Pressure: Yea Or Nay?
We hear a lot about high blood pressure — almost half of all American adults are afflicted with this.(1) But what about low blood pressure?
It’s hard to nail down an exact percentage of the population that has low blood pressure, aka hypotension. This is largely because it’s often a silent or transient condition. However, experts agree that some degree of low blood pressure is common — maybe even about 50% of people experience a hypotensive episode.(2)
Given the prevalence of low blood pressure and popularity of CBD, people want to know if the two mix. They’re interested in understanding things like:
- How does CBD affect blood pressure?
- Can CBD lower blood pressure?
- Can you take CBD if you have low blood pressure?
Hypotension — What’s That?
The optimal range for healthy blood pressure (BP) between 90/60 and 120/80 (systolic/diastolic). For most healthy adults, their BP is somewhere in this ballpark. (3,4,5)
Hypotension is the medical name for low blood pressure, or a BP that’s below 90/60.
Types Of Hypotension
A person can have occasional low blood pressure that’s pretty much NBG and requires no treatment. It’s likely that everyone experiences a bout of hypotension at some point in their lives. Low BP gets to be a concern if it’s persistent or causing other problems (like fainting and falling).
Not all hypotension is the same. There are different sorts of low blood pressure, including:
- Orthostatic or Postural Hypotension
- Neurally Mediated Hypotension
- Postprandial Hypotension
- Shock-Related Hypotension
Low Blood Pressure Symptoms
Hypotension can be symptomatic or asymptomatic. But, if low BP were to rear its head, it might look something like this:
- Distorted vision
- Shallow, fast breathing
- Trouble concentrating
- Unusual behavior
Causes of Low Blood Pressure
This condition has lots of potential causes, including:
- Allergic reactions
- Being on bed rest
- Body position
- Breathing rhythm
- Nervous system diseases
- Certain medications
- Drugs and alcohol
- Exposure to extreme temperatures
- Heart and lung conditions
- Losing a lot of blood
- Metabolic or endocrine conditions
- Severe infections
- Some supplements or home remedies
Not all of these causes are associated with all types of hypotension. Each kind of low blood pressure has its own subset of possible causes and triggers.
Age, sex, time of day, and other factors can impact the likelihood of low BP, too.
The treatment protocol is different for each form of low blood pressure and each person. If your doctor determines it’s necessary for intervention, he or she could recommend a variety of lifestyle changes and medical therapies. These could include:
- Dietary changes
- Relaxation techniques
- Physical movement
- Compression stockings
- Hormone therapy
- IV fluids
- Blood transfusion
If the hypotension is brought on by and underlying condition, your healthcare provider will work to help you resolve that.
CBD & Blood Pressure
So, you’re probably wondering how CBD impacts blood pressure and if it’s a viable therapeutic or recreational option right about now.
As a quick refresher, CBD is the common name for the cannabinoid cannabidiol. CBD is non-psychoactive and is well-reputed for its many potential mental and physical wellness benefits. It may help with various health concerns that relate to blood pressure.
How CBD Impacts Blood Pressure
According to research, CBD appears to move the dial on blood pressure in a few ways.
Studies show that CBD lowers blood pressure and diminishes the blood pressure response to increased heart rate.(6) A double whammy to hypertension!
Besides these direct methods, CBD can indirectly act on blood pressure. It does this by affecting levers like psychological and emotional, lifestyle, and other contributors to high BP. For example, CBD could help reduce stress and anxiety — and with lower stress and anxiety levels, a person may have better blood pressure trends.
And again, CBD has a rep for supporting general well-being. People with more robust health tend to have lower risk factors for cardiovascular, metabolic, and other disorders that may lead to blood pressure problems. Their bodies stay closer to that healthy balanced zone: homeostasis.
CBD & Hypotension
Bluntly, there seems to be little existing research on this. Most of the focus is on CBD and high blood pressure (hypertension).
Fortunately, we can glean a lot of useful info from those investigations into cannabinoids and blood pressure. (For an in-dept look at CBD and high BP, check out Does CBD Oil Raise Blood Pressure? next.)
Here’s what the clinical data and academic papers are finding:
- THC — a fellow cannabinoid often found in CBD oil products — can either lower or raise blood pressure. The effect hinges on a number of things like how much THC was consumed and how a person’s body metabolizes the cannabinoid.(7)
- CBD opens up blood vessels, which can lead to improved blood flow and lower BP.(8)
Researchers continue to delve into the effects of cannabinoids on blood pressure and contributing conditions. However, many clinical trials exclude patients with hypotension, so it may make it difficult to derive direct insights.
Using CBD With Low Blood Pressure
As always, it’s advisable to talk to your doctor before using CBD if you have pre-existing medical conditions or take medications or supplements. Your doc will be able to tell you if CBD is a no-go based on your health profile — including considerations related to your blood pressure.
You physician can evaluate and diagnose hypotension and hypertension. If you have blood pressure issues, your physician can discuss all your options with you. There are likely to be natural solutions you can incorporate in your care plan. CBD may or may not be on that list….
Assuming your care provider, gives the two-thumbs-up signal for you to try CBD:
- Be sure to use the purest, highest-quality CBD products around. You’ll up your chances of having better results!
- And, you may want to opt for full-spectrum CBD or broad-spectrum CBD products. They contain at least trace amounts of THC, which may help modulate the blood-pressure altering effects of the CBD.
Can You Take CBD If You Have Low Blood Pressure? Maybe…
There are different kinds of hypotension (low blood pressure). Depending upon your body, your variety of low blood pressure, and the type of CBD you consume — CBD may lower your blood pressure even more.
Consult with your doctor prior to taking CBD, especially if you have hypotensive experiences. Your physician is in a position to help you better address health concerns and advise on whether or not CBD is appropriate for you.
CBD and Blood Pressure: What Does Science Say?
High blood pressure, or hypertension, is a significant issue. It increases the risk of heart disease and strokes, two of the leading causes of death in the USA. The condition affects approximately 45% of American adults. Furthermore, only 1 in 4 of these people have their blood pressure under control.
Therefore, some may wonder if natural remedies like cannabidiol (CBD) could help. But unfortunately, the relationship between CBD and blood pressure is not straightforward. This article explains the current research on CBD oil for hypertension and whether it is worth trying.
What Is Hypertension?
Before we look at CBD’s possible effects, we will briefly overview hypertension, its symptoms, and its causes.
The term “blood pressure” relates to how much force blood exerts on the vessels as it passes through them. It is measured in units called millimeters of mercury (mmHg).
Blood pressure can be subclassified as systolic or diastolic. Systolic readings measure the force on the blood vessels when the heart muscle contracts. Meanwhile, diastolic blood pressure readings measure the force when the heart muscle relaxes.
In hypertension, the blood’s force on the vessels becomes greater than usual, increasing the risk of heart disease and strokes.
In hypertension (high blood pressure), the blood’s force on the vessels becomes greater than usual. This increases the risk of heart disease and strokes. Some people also use the phrase “elevated blood pressure.” This means that blood pressure is increased, but not significantly.
People with elevated blood pressure could control their condition by making healthy lifestyle changes. However, people with stage 1 or stage 2 hypertension usually require medication.
The table below illustrates what constitutes normal, elevated, and high blood pressure:
Stage 1 Hypertension
Stage 2 Hypertension
Some refer to hypertension as “the silent killer” because it does not usually cause any symptoms until serious problems arise. This is why regular blood pressure check-ups are essential, especially for those at high risk (see below).
In severe cases, a hypertensive emergency can occur. It involves a sudden and dramatic increase in blood pressure, which is extremely dangerous. The condition can cause various symptoms, including:
- Shortness of breath
- Chest pain
- Reduced urination
- Visual changes, such as blurring
Anyone experiencing these high blood pressure symptoms should seek urgent medical attention.
What Causes High Blood Pressure?
Blood pressure increases naturally with age as the artery walls become less elastic. However, several other risk factors can contribute to the development of hypertension:
- Ethnicity (people of African-American or Hispanic descent are at higher risk)
- Family history
- Diabetes or metabolic disorder
- Kidney disease
- Some types of tumors
- Sleep apnea
- Thyroid dysfunction
- Being overweight or obese
- Some medications
Some other potential causes of high blood pressure are lifestyle-related, for example:
- High salt diets
- Low potassium intake
- Excessive caffeine or alcohol consumption
- Lack of exercise
- Lack of sleep
- Some illicit substances, including cocaine, methamphetamine, and “bath salts”
Exploring the facts. …
Does CBD Lower Blood Pressure?
CBD is a cannabinoid, one of the numerous active compounds that cannabis plants produce. Until recently, it lived under the shadow of its intoxicating cousin, tetrahydrocannabinol (THC). However, research shows that CBD has great potential for treating various conditions. So, what about CBD for high blood pressure?
Many people know that THC can reduce blood pressure, and this is why some cannabis users experience dizziness as a side effect. However, we understand less about CBD and how it influences the body. That said, it seems that both chemicals could work similarly by relaxing the blood vessels.
This reaction is probably due to how cannabinoids interact with the body’s endocannabinoid system (ECS). It is an intricate network of cell receptors (CB1 and CB2) and chemicals called endocannabinoids. When they bind together, they regulate a vast range of physiological processes that help maintain a state of balance within the body.
Both THC and CBD can also influence this system. THC binds directly with CB1 receptors to mimic the activity of an endocannabinoid called anandamide. Anandamide has many functions, including relaxing the blood vessels to reduce blood pressure.
However, CBD acts differently. Scientists are still trying to understand its precise mechanism, and it seems to work in several ways. It appears that rather than binding directly with CB receptors, it indirectly increases anandamide levels.
This is why CBD produces many of the same benefits as THC but without intoxicating effects. It works gently within the body rather than overstimulating it. Unfortunately, though, the compound is still very much understudied. Therefore, CBD oil blood pressure research is thin on the ground.
Studies on CBD Oil and Blood Pressure
There are a handful of studies on CBD’s effects on blood pressure. However, their results are very mixed. It seems that they depend upon the species, testing methods, and whether the subjects are healthy or hypertensive.
For example, a 2017 study of nine healthy male volunteers published in JCI Insight had promising results. It investigated the impact of a single 600mg CBD dose under both normal and stressful conditions. The researchers found that the CBD reduced resting systolic blood pressure by an average 6mmHg, and it did not affect diastolic pressure.
However, the effects were more pronounced when they subjected the participants to mental, exercise-induced, and cold stress. CBD seemed to influence both systolic and diastolic blood pressure in these experiments.
Under stressful conditions, CBD seemed to influence both systolic and diastolic blood pressure.
Unfortunately, this study had several flaws. Firstly, the subjects were healthy rather than hypertensive, and they were young, with an average age of 23. Furthermore, the researchers only tested the effects of a single, large CBD dose. Therefore, while interesting, these results are not representative of real life.
A 2020 study resolved some of these issues, using hypertensive test subjects and administering CBD daily for two weeks. However, the subjects were rats rather than humans. It found that CBD did not reduce blood pressure or heart rate. However, it did provide potentially beneficial antioxidant effects.
Different Species, Different Tissue Types, Different Results?
Another 2020 study suggested that CBD might affect rats and humans differently. Its authors proposed that while the compound interacts with CB1 receptors in rats, this might not happen in humans.
They explained that the mechanism in humans is far more complex and involves several other receptor types. However, they tested different cell types for each species, using human lung artery cells and rats’ abdominal artery cells.
Interestingly, an earlier 2015 study had tested CBD on the same type of abdominal artery cells from humans. It found that, in this case, the cannabinoid did influence CB1 receptors and other types.
Is it possible that CBD could affect various species and tissue types differently? Only further research will tell. Far more studies are necessary to fully understand the link between blood pressure and CBD.
The revealing truth about CBD…
Can CBD Oil Raise Blood Pressure?
Another valid question is, “can CBD raise blood pressure?” However, research on this subject is even harder to find.
A 2017 systematic review found that CBD did not affect blood pressure or heart rate under normal conditions. However, it did find that the cannabinoid significantly decreased these measures in stressful circumstances.
It also discussed the long-term effects of CBD by looking at clinical trials on epilepsy, Huntington’s disease, and schizophrenia. It found no changes in blood pressure in any of these studies.
One study on intraocular pressure (IOP) found that CBD temporarily increased IOP, which is related to blood pressure. These effects occurred after a single 40mg dose. Therefore, individuals with already raised IOP should exercise caution and consult a doctor before using CBD.
CBD and Blood Pressure – What Is the Best Product Type?
First and foremost, we must point out that research into CBD’s effects on blood pressure is ongoing. At present, there is no evidence available to suggest that a specific form of CBD is more or less effective than another.
We can tell you that vaping seems to provide higher bioavailability than CBD oils consumed sublingually or an edible consumed orally. This means that a greater percentage of the cannabidiol in a vape product is absorbed. Also, CBD vape juice could have an effect in a matter of seconds. Meanwhile, it tends to take at least 15 minutes for an oil to affect, whereas a CBD edible might not show any noticeable benefits for 30-90 minutes.
However, there are certain health concerns attached to vaporizing in general. Research by Harvard University outlined the possible damage caused by vaping.
Also, thinning agents such as vegetable glycerin (VG) and propylene glycol (PG) are widely used in CBD vape liquids. While they are generally classified as safe for human consumption, they could release carcinogens when heated. A study published in 2017 found that when heated to 448 degrees Fahrenheit, PG produced a high level of formaldehyde, a known carcinogen.
Furthermore, a 2020 study found that vaping e-liquid containing a mix of VG and PG might result in lung inflammation.
As a result, if you’re concerned about the effects of vaping, you might decide that CBD products such as oils and gummies from brands like Premium Jane and Hemp Bombs are better options.
CBD Effects on Blood Pressure – Is It Safe to Use?
The effects of CBD on blood pressure are not well studied enough to draw informed conclusions. There is nowhere near enough evidence from studies on humans to determine whether it is safe to use CBD to increase or decrease blood pressure.
The main study outlining that CBD reduces blood pressure involved a large single dose and young, healthy volunteers. Other research showed a slight increase in IOP from a smaller dosage, whereas animal studies are inconclusive. Indeed, there’s a possibility that the cannabinoid impacts humans and rats differently.
Therefore, individuals with hypertension or hypotension should approach CBD with caution and use it sensibly. If you’re concerned about taking CBD but wish to lower blood pressure, here are some other actions you can take:
- Decrease your sodium intake
- Find healthier ways to deal with stress
- Lose weight if you’re carrying extra pounds
- Exercise regularly
- Consider following the Dietary Approaches to Stop Hypertension (DASH ) diet
CBD Dosage for High Blood Pressure
Once again, we must point out that there are no clinical guidelines regarding CBD dosage for ANY medical condition, let alone as a means of managing blood pressure levels.
However, if you recall, the JCI Insight study from 2017 involved the consumption of 600mg of CBD. Given that 1,000mg of high-quality CBD can cost over $100, regularly using such a large dose is not financially viable for most people.
Then again, it is worth remembering that another study saw an increase in IOP from a single 40mg dose. Ultimately, it is worth following conventional wisdom, suggesting it is best to take a “low and slow” approach. This involves using a small amount of CBD (perhaps 5mg to 10mg) daily at first to see how it affects you. Gradually increase the dose until you’re satisfied with the results.
Final Thoughts on CBD Oil for High Blood Pressure
When it comes to choosing an effective CBD oil, there are several considerations.
First and foremost, consumers should know that the market is not well-regulated. Therefore, products can vary greatly in terms of quality. Look for a reputable brand that publishes lab reports on its website. These indicate exactly how much CBD is in each item and ensure it is free from other contaminants.
Full-spectrum CBD oils contain a range of other cannabinoids and terpenes, including traces of THC.
Secondly, check whether the product is full-spectrum, broad-spectrum, or CBD isolate. Full-spectrum CBD oils contain a range of other cannabinoids and terpenes, including traces of THC. Since THC may also help lower blood pressure, this might be a better option. Individuals in states with legal marijuana could even look for products with higher levels of THC.
Finally, consider the overall quality of the product. This might include where the hemp was grown, whether it is organic, extraction processes, and more. Online reviews provide a fantastic way to learn from previous customers about each company’s pros and cons. You can also find out how the WayofLeaf team rated various products in our CBD brand reviews section.
