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.
CBD for Heart Disease
Heart disease is a catchall phrase for the disease that develops when the arteries of the heart cannot deliver enough oxygen-rich blood to the heart, leading to events like heart attack. It’s the leading cause of death in the United States, killing about 655,000 Americans each year, which is about one in every four deaths. Key risk factors for heart disease include unhealthy diet, physical inactivity, diabetes, overweight and obesity, and excessive alcohol use.
Similarly, a stroke, which is sometimes called “ brain attack,” occurs when blood flow to the brain is blocked or reduced. So the same precautions that protect against heart attacks and other cardiovascular disease (like diet, exercise, and a healthy lifestyle that can include CBD supplementation) can help prevent stroke. CBD can also play a key role in protecting the brain after a stroke.
Inside Your Arteries
Research shows that CBD can help maintain healthy cardiovascular function and prevent heart disease on a number of fronts, including protecting against hardening of the arteries, lowering blood pressure, and reducing the incidence of potentially dangerous arrhythmias.
It starts inside your arteries. When the linings of your artery walls are injured, they build up plaque that can cause the arteries to narrow. This is called atherosclerosis; it’s a prevalent form of heart disease. Inflammation is a leading cause of this type of injury, as is high blood pressure. Exposure to tiny chronic doses of THC has been shown to slow the progression of atherosclerosis in animal studies.
THC and CBD are both vasodilators, meaning they widen your blood vessels, a process regulated by the endocannabinoid system. This can have a pronounced positive effect on blood pressure. In a 2017 study, British researchers gave a group of men either 600 mg of CBD or a dummy supplement and monitored their blood pressure at rest and again after stress tests that normally increased blood pressure. Just that single dose of CBD reduced the participants’ resting systolic blood pressure by 6 mmHg. Plus, they had less of a spike in blood pressure in response to stress than those taking a single dose of a placebo pill.
In a follow-up study, where the researchers gave 26 men 600 mg of CBD or a placebo for seven days, the results were mixed. Measurements of resting blood pressure revealed that the participants had developed a tolerance to the CBD over time, but CBD ’s ability to lower blood pressure during stress persisted. (Of course, if you are already dealing with low blood pressure, the blood pressure–reducing effects of CBD are something to be aware of, and you may need to avoid high doses.)
“The reduction of arterial stiffness, and improvements in internal carotid artery blood flow and endothelial function after chronic CBD treatment, indicate a positive effect in vascular function that warrants further investigation in relevant patient populations,” lead researcher Saoirse E. O’Sullivan, PhD, reported.
CBD may also protect against cardiac arrhythmias, or irregular heartbeats, where the heart beats too fast, too slowly, or with an irregular pattern. Arrhythmias can be brought on by long-term stress, as high cortisol levels can raise blood pressure, blood cholesterol, blood sugar, triglycerides, and other risk factors for heart disease in general. CBD ’s anti-anxiety properties can help combat stress, lower cortisol, and protect against arrhythmias related to those causes.
CBD may protect against cardiac arrhythmias or irregular heartbeat.
Research shows that CBD also can suppress irregular heartbeat caused by stroke-induced ischemia (inadequate blood supply to the heart) and can minimize tissue damage caused by the lack of oxygen. A study published in the British Journal of Pharmacology found that when rats were given CBD 10 minutes before a 30-minute coronary artery occlusion (partial or complete obstruction of blood flow in the coronary artery, which may cause chest pain, heart attack, and tissue damage) or 10 minutes before blood flow was restored, they experienced fewer arrhythmias and less tissue damage than rats not given CBD . Research in this area is still in the early stage, but it already shows great potential.
Since cannabinoids also mop up free radicals — and improve the effects of other antioxidants in the body — CBD may also protect against heart disease by reducing the cellular damage that happens when we’re exposed to free-radical producers like processed foods and environmental pollution.
CBD also delays the reabsorption of a chemical called adenosine (meaning that you have more of it in circulation), which quells inflammation and helps maintain healthy heart function.
If you’re already taking medications for blood pressure, cholesterol, or other heart conditions, it’s important to consult with your doctor before you start taking CBD . High doses of CBD may interfere with the metabolism of some of these drugs, which could have problematic consequences.
