Heart health is one of the areas being explored to determine the therapeutic health benefits of cannabidiol (CBD). Nearly 655,000 Americans die from heart disease every year, accounting for one in every four deaths.
CBD cannot cure heart disease or congestive heart failure, but it is being studied for ways it may help reduce symptoms or prevent heart disease. However, CBD has not been shown in large studies to prevent diseases that lead to heart failure.
Read on to learn more about CBD’s benefits for the heart, what CBD oil is, side effects, and forms of CBD oil.

What Is CBD Oil?
Cannabidiol oil is extracted from the leaves and flowers of the cannabis plant. CBD is a chemical that’s unique to the cannabis plant. The two major cannabinoids contained in cannabis plants are:
- Tetrahydrocannabinol (THC): It has psychoactive properties that create a “high” feeling.
- Cannabidiol (CBD): It has no psychoactive effects but provides several therapeutic benefits.
Both CBD and THC interact with the endocannabinoid system (ECS) in the body. The ECS is a complex biological system that impacts many of the body’s functions, including appetite, memory, mood, and sleep. Researchers are learning that the endocannabinoid plays a role in the function of the cardiovascular (heart) system.
A growing body of evidence shows that dysregulated ECS is associated with a number of cardiovascular diseases. Whether you have a heart condition or want to prevent heart disease, CBD may boost your endocannabinoid system to help it regulate the cardiovascular system.
Overview of Heart Failure
Heart disease is an umbrella term that refers to several types of heart conditions. Heart disease may involve the heart valves, arteries, and heart rate, leading to heart failure.
Heart failure is a serious health condition in which the heart isn’t pumping the way it should be. The body depends on the heart’s pumping action to deliver oxygen and nutrient-rich blood to all of its cells.
With heart failure, the heart cannot supply the body’s cells with enough blood, leading to symptoms that can have a tremendous impact on your quality of life.
Heart failure has a number of causes, including genetics, other medical conditions (e.g., anemia, diabetes, sleep apnea), and lifestyle (e.g., smoking, obesity).
Symptoms of heart failure vary, depending on the type and severity of heart failure you have. Common symptoms include:
- Shortness of breath
- Increased heart rate
- Bluish-colored fingers and/or lips
- Persistent coughing or wheezing
- Lack of appetite
- Trouble concentrating
- Inability to sleep when lying flat
CBD and Heart Health
CBD has anti-inflammatory, antioxidative properties that may help reduce risk factors that can lead to heart disease. It may also be helpful in reducing the risk of related conditions, such as stroke.
Research suggests that even a single dose of CBD can lower blood pressure. High blood pressure has been linked to congestive heart failure. This is because high blood pressure makes it more difficult for blood to travel easily throughout the body, causing the heart to work harder.
While more research is needed to be sure, CBD may be helpful in lowering blood pressure to prevent congestive heart failure.
CBD oil has anti-inflammatory properties, which may help reduce cholesterol levels to improve heart health. Cholesterol is a type of lipid (fat) found in the blood.
High cholesterol levels—particularly low-density lipoprotein (LDL), aka “bad” cholesterol—increase the risk of developing cardiovascular diseases. LDL can build up in the lining of blood vessels, causing a blockage that can lead to heart attack or stroke.
CBD has properties that help relax arterial walls, which research suggests may help reduce blood pressure and excess cholesterol. In animal studies, CBD has been shown to increase HDL levels—aka “good” cholesterol—and lower LDL levels after four weeks of CBD supplementation.
CBD is perhaps best known for its anti-inflammatory properties. Research suggests that inflammation may be at the root of many chronic illnesses. Heart disease is associated with inflammation. Inflamed blood vessels make it harder for the heart to pump blood throughout the body.
One study found that CBD has a direct effect on the arteries, helping reduce inflammation and improving blood flow. This suggests that CBD reduces inflammation in arteries and blood vessels, easing the strain on the heart, potentially preventing heart failure.
Obesity is one of the leading causes of congestive heart failure, which is one reason why it is important to maintain a healthy weight for optimal heart health. There is some evidence to suggest that CBD may help maintain a healthy weight.
One study found that CBD promotes the browning of white fat cells, which aids in converting the fat into burnable calories. This is beneficial because brown fat cells contain more mitochondria than white fat cells, which helps burn calories. White fat cells contain droplets of fat that accumulate around the body and can lead to obesity.
Are There Any Side Effects?
CBD has few side effects, and the World Health Organization states that it is generally well tolerated and has a good safety profile. While relatively safe, there are a few things to consider before you try CBD.
If you are currently taking any other medications, speak with your doctor before trying CBD. Some research suggests that CBD may interfere with the way the liver processes certain medications.
This interference may prevent the liver from metabolizing other medications as it normally would, leading to higher concentrations of the medication in the body and increasing the risk of liver toxicity.
Best CBD for Heart Health
CBD comes in many different forms, including oils and tinctures, edibles, topicals, and vaporizers. Taking CBD oil sublingually (under the tongue) is an easy way to enjoy the benefits. Using sublingual oils tends to work faster and produce stronger results than other edible products, such as gummies.
Vaping CBD is a fast way of delivering CBD into your system, but it is not recommended for individuals with heart disease. Vaping is associated with lung damage, and research shows it causes an increased risk in developing cardiovascular disease.
There are a number of CBD types to choose from. Understanding these differences can help you choose which type is best for your needs. These types include:
- Isolate: CBD is the only cannabinoid contained in the product.
- Full-spectrum: Contains multiple naturally occurring cannabis plant extracts, including terpenes, other cannabinoids, and up to 0.3% THC.
- Broad: Contains CBD and other components/cannabinoids found in the cannabis plant, but does not contain any THC.
The availability of these products varies from state to state, particularly for products that contain THC.
If you’re just starting off with CBD, try a small dose first. Watch for any side effects. If you wish, you can slowly increase your dosage (no more than 5 to 10 mg increase at a time) until you find the dosage that is right for you.
How to Buy CBD
With so many CBD options available, shopping for the right product can be an overwhelming experience. Some important things to keep in mind when buying CBD include:
- Cannabis source: CBD is derived from cannabis plants, and it’s important the CBD is sourced from a company that takes care in the quality and cultivation of their plants. Look for products that come from organic plants when possible.
- Certificate of Analysis (CoA): Responsible, reputable manufacturers offer a CoA that clearly states the amounts of cannabinoids in a product. CoAs are conducted by an independent, accredited lab.
- Read the label: Read the full list of ingredients contained in CBD to know what you are consuming.
- Type of CBD: To get the best results, look for full-spectrum or broad CBD products. These may offer an “entourage effect,” combining the effects of multiple cannabis compounds that work in synergy to offer the most benefits.
CBD oil is extracted from the cannabis plant. It has anti-inflammatory and antioxidative properties. Researchers are looking into ways it could be beneficial for heart health. While it has few side effects, it may slow liver metabolism and affect other medications you are taking.
Cannabidiol comes in several forms and methods of application. People with heart disease should avoid products that require vaping or smoking.
A Word From Verywell
While CBD is not a cure for heart failure, it may prevent further damage thanks to its anti-inflammatory properties. CBD may be helpful in reducing blood pressure, decreasing inflammation and cholesterol, and maintaining a healthy weight. Improving these factors may reduce the risk of heart failure.
Speak with your doctor before trying CBD, particularly if you are on any other medications or dietary supplements. Your doctor can let you know if it is safe to take, and may have product and/or dosage recommendations.
Frequently Asked Questions
How safe is CBD for congestive heart failure?
CBD is generally considered to be safe for congestive heart failure. Research shows no significant adverse effects of CBD at a wide range of doses (anywhere from 3 to 1,200 mg/day).
CBD has significant potential to treat a variety of heart diseases and comes with few adverse side effects, though more research is needed. Talk with your doctor before using CBD for heart disease, particularly if you are currently taking any other medications.
Does CBD lead to heart problems?
CBD alone does not lead to heart problems. However, CBD is broken down and metabolized by the liver. During this process, it may interfere with your medications for any heart conditions you have. This may lead to liver problems or interfere with the effectiveness of any medications you are taking.
Exercise caution and speak with your doctor before using CBD for heart failure.
Can CBD cause heart palpitations?
The cardiovascular effects of CBD are currently being studied. Some research suggests that cannabis use may cause arrhythmia (irregular heart rate) or tachycardia (increase in heart rate).
However, those studies included products that also contain THC, the psychoactive cannabinoid found in cannabis plants. More research is needed to determine if CBD causes heart palpitations.

What Are The Benefits of CBD Oil For Heart Disease?
There are many different forms of heart disease — some are serious and life-threatening; others are more benign.
CBD may be a useful supplement for alleviating common side-effects of heart disease, and in some cases, can help mitigate the underlying causes of the condition.
CBD could be especially beneficial to people suffering from atrial fibrillation (or other arrhythmias) associated with anxiety and inflammatory causes, including atherosclerosis. Future studies should be done to directly investigate the relationship between taking CBD and cardiac health outcomes in humans.
Most patients with heart disease use CBD to alleviate comorbidities such as anxiety, inflammation, insomnia, and depression.
Potential Benefits of CBD for Heart Disease:
- Stabilizes blood sugar levels 
- Promotes weight loss
- Decreasesinflammation 
- Lowers blood pressure in the face of acute stress 
- Protects the arteries from oxidative stress 
How to Use CBD Oil for Heart Disease
Heart disease is a serious condition that requires the oversight of an experienced medical professional.
Always consult your doctor before taking any supplements — including CBD.
It is important to know that CBD will not stop chest pain or a heart attack in progress. If you have symptoms like squeezing or crushing chest/arm/jaw pain, nausea, with excess sweating – you should call emergency medical services or go to your nearest emergency room right away.
After calling for help in such a situation, chewing one adult-dose aspirin (325 mg), or up to 4 baby aspirins (81 mg each x 4 = 324 mg) at once, with water has been shown to reduce mortality in heart attack patients.
Be sure not to just swallow without chewing, and avoid enteric-coated aspirin — the idea is to ingest aspirin as fast as possible after calling for help.
Do not take aspirin if you are allergic to it, and do not give it to a child unless directed by a physician. Even if you take aspirin daily, you should take another one at the onset of heart attack symptoms.
Don’t start or stop taking aspirin daily unless your doctor has told you so.
It’s also important to note that CBD may interact with medications, including sensitive heart medications such as cardiac glycosides and blood thinners. While CBD has been proven safe in both animal and human trials, it may be necessary to decrease your dose of CBD if you are on one of these common heart medications.
To get the most out of your CBD supplementation, look for companies that use certified organic hemp and avoid those that don’t list their third-party lab results publicly on their website. Any contaminants in low-quality oils could make underlying causes for heart disease even worse, so it’s critical to ensure you only use high-quality products.
We also recommend using full-spectrum oils over CBD isolates because they contain other cannabinoids in the cannabis plant that offer their own set of benefits toward inflammation, blood sugar regulation, and anxiety — all of which are critically important in the underlying causes and sustaining factors of heart disease.
What Form of CBD Should I Use?
Choosing what type of CBD to use out of all the options can seem intimidating at first — there’s capsules, oils, tinctures, suppositories, edibles, gummies, vape oils, coffee, and numerous other forms depending on the company.
The truth is that most of these will work just fine. In all forms except topical CBD, the result is the absorption of CBD into the bloodstream.
With that said, CBD oils, tinctures, and capsules offer distinct advantages over the other options when it comes to heart disease.
The benefit of CBD oils and tinctures is that the dose can be individually measured more easily than most other forms. Once you’ve determined the amount of CBD contained in each milliliter or drop of fluid, it’s easy to tweak the dose according to how it affects you individually.
CBD capsules are also an excellent option and are considered by many to be the most convenient form of dosing CBD.
Tips for Optimizing CBD Supplementation
- Use a full-spectrum extract
- Use CBD over the long term for the best results
- Make dietary and lifestyle changes
- Discuss CBD use with your doctor to avoid drug interactions
- Use oral CBD only
- Avoid cigarette smoking and other tobacco product use at all costs
What’s the Dose of CBD?
The required dose of CBD can vary from one person to the next. This is because the compound affects everyone differently depending on the health of the liver, your prescriptions, digestive tract, and genetic variability in the endocannabinoid function throughout the body.
For this reason, most people need to do some trial and error when trying CBD for the first time.
The best way to do this is to start with the lowest dose on our chart below according to your weight and build up gradually each day by adding 2 mg or 3 mg of CBD. Once you find relief from your symptoms, you’ve found the correct dose for you.
It’s important to note that some people end up at a dose far higher than those listed on the chart below. In general, the maximum dose of CBD should be around 100 mg, but this can vary from person to person, and CBD is considered highly safe even at large doses.
