Restless legs syndrome (RLS) causes unpleasant sensations in the legs, along with an overwhelming urge to move them.
Symptoms tend to be strongest in the evening, when you’re least active. They can also flare up when you lie down in bed. RLS can make it difficult to get a good night’s sleep, which can become a serious quality-of-life issue.
Some anecdotal evidence suggests that cannabidiol (CBD) may help ease symptoms of RLS. However, there haven’t been many studies focusing on CBD for RLS.
This article will cover the research, potential benefits, and side effects of using CBD for RLS, along with information about dosage and the types of CBD products that are available.

What Is CBD?
CBD is a cannabinoid, a naturally occurring compound found in the cannabis plant.
It’s not the same as medical marijuana. Marijuana contains a significant amount of another cannabinoid called tetrahydrocannabinol (THC). THC is the substance that produces psychoactive effects that make you feel “high.”
CBD is extracted from hemp. The difference between marijuana and hemp is the amount of THC. Hemp contains less than 0.3% THC, which isn’t enough to get you high.
THC vs. CBD
Cannabis is a plant of the Cannabaceae family. Cannabis products come from its leaves, stems, seeds, and flowering tops. Cannabis contains more than 120 naturally occurring substances called cannabinoids. THC and CBD are two of the main cannabinoids. THC is the substance that produces a high. CBD is a nonintoxicating substance that may have therapeutic effects.
Research Around CBD and RLS
There hasn’t been much research to assess the effectiveness of CBD in the treatment of RLS.
It does appear, however, that some people are using it for that purpose. In a small 2021 survey based primarily in the United Kingdom, more than 42% of respondents said they used CBD to improve sleep or for insomnia, while another 5% reported using CBD for RLS.
A small 2019 study on the efficacy of smoking cannabis for RLS suggests that regular use of cannabis may reduce symptoms of RLS. A notable limitation is that study participants smoked cannabis containing THC. It’s possible that results are distorted by THC’s psychoactive and antianxiety properties.
More large-scale studies on CBD and RLS are needed.
Types of CBD Products
The three main types of CBD products are:
- CBD isolate: This type is also called “pure CBD” because all other cannabinoids have been removed.
- Broad spectrum: This type contains three or more other cannabinoids. It may have terpenes and flavonoids, which provide aromas, flavors, and colors. It does not contain THC. : Also known as “whole flower CBD,” it’s almost the same as broad spectrum. However, it can contain up to 0.3% THC.
These products are available in many forms, including:
- Oral tablets and capsules
- Chewables and gummies
- Tinctures, oils, and extracts
- Patches, creams, and lotions
What to Look for in CBD Products for RLS
Once you decide on the type of CBD product, it’s important to look for a reputable source.
According to the Food and Drug Administration (FDA), some CBD products are marketed with unproven medical claims and are of unknown quality. The agency hasn’t approved any nonprescription CBD products.
CBD products sold in dispensaries must have a label that lists exactly how much CBD it contains. It should also state whether it contains THC.
If you don’t have access to a dispensary, another good option is a trusted pharmacy. You can also buy CBD products online, but be careful about the source. One study of online CBD products found that:
- 31% were accurately labeled.
- 43% had more CBD than labeled.
- 26% had less CBD than labeled.
No matter where you get CBD, always ask for a certificate of analysis (COA). This document provides information such as:
- The date of the report, so you know it’s recent
- The name of the third-party lab that performed the testing, along with its license number
- The potency of a variety of cannabinoids, including CBD and THC
- Whether the product passed safety tests for contaminants
Things to avoid:
- Illegally sold synthetic CBD products, including those marketed as “bath salts” or “spice,” which can cause a psychotic reaction in some people
- CBD added to food or labeled as a dietary supplement, which is illegal
- Products that claim to prevent or cure a health condition
- Products that list only “total cannabinoids” rather than breaking them down separately
- Products without a COA
CBD Dosage for RLS
The FDA has approved prescription CBD products for the treatment of certain seizure disorders. The agency hasn’t granted approval for any other use. And because research on CBD for RLS is limited, there’s no standardized dose.
It’s best to start with a low dose and build up slowly, if needed. Discuss dosing with a healthcare provider or pharmacist and ask about possible interactions with any medicines or supplements you take.
Benefits of CBD for RLS
People from all walks of life are using CBD for specific health conditions, including RLS and sleep problems. Many say CBD helps in the absence of conventional medicine alternatives and with few troublesome side effects.
Since research specific to CBD for RLS is scarce, the benefits are unclear. If you try CBD for RLS, it may be helpful to keep a journal of the CBD product, dose, and your response. Over time, this may clarify whether it’s beneficial for you.
Side Effects of CBD for RLS
CBD is a naturally derived product, but natural products can cause side effects. Side effects of CBD can include:
- Decreased appetite
- Upset stomach
Due to limited controlled studies, there’s not enough information to properly assess risks such as:
- Cumulative effects
- Food interactions
- Effects on older populations, children, and adolescents
- Effects during pregnancy or while breastfeeding
- Interactions with common medications
There may be an increased risk of liver damage in people who take medicines that affect the liver. There may be interactions between CBD and immunosuppressive drugs used for organ transplants, as well as with chemotherapy or Coumadin or Jantoven (warfarin).
Other Treatment Options
There’s no cure for RLS, though it’s possible to minimize symptoms and improve sleep. You may not need treatment if your symptoms are mild.
- Avoid or cut back on alcohol and tobacco.
- Set up a regular sleep schedule, going to bed at the same time each night and getting up at the same time each morning.
- Perform leg-stretching exercises and massage your legs as needed.
- Take a warm bath before bed.
- Apply an ice pack or heating pad to your legs.
- Try a compression foot wrap or a pad that delivers vibration to the back of your legs.
Medications to treat RLS include drugs that affect dopamine levels, such as:
- Requip (ropinirole)
- Mirapex (pramipexole)
- Neupro (rotigotine)
Sometimes, anti-seizure drugs can help with symptoms of RLS. These include:
or gabapentin enacarbil
If those medications don’t work, opioids may be an option. These may include:
Benzodiazepines such as clonazepam and lorazepam may help improve sleep.
Each of these drugs can produce serious side effects. It’s important to discuss the potential benefits and side effects with your healthcare provider.
Is Medical Marijuana Effective for RLS?
Research on the use of medical marijuana for RLS is limited. There are reports of total remission, suggesting that more scientific research, including controlled trials, is warranted. Marijuana contains THC, which can get you high. It also contains other substances that produce different side effects than CBD does.
RLS causes uncomfortable sensations in the legs along with a powerful urge to move them. Symptoms usually occur in the evening, when you’re at rest or in bed.
RLS can make it very difficult to fall asleep and stay asleep, which can have a negative effect on your quality of life. There are medicines to treat RLS, but they don’t help everyone.
CBD is one of hundreds of cannabinoids in cannabis plants. Unlike THC, it doesn’t produce a high. CBD is available in many forms, including chewables, tinctures, and sprays.
It appears that many people have used CBD for symptoms of RLS. And many report that it helps without causing serious side effects.
Unfortunately, CBD for RLS is not well studied. There’s a lack of information regarding proper dosing and the effects of long-term use.
A Word From Verywell
Living with RLS can be challenging, especially if lifestyle changes or medicines aren’t helping. If you’re considering trying CBD, it’s a good idea to speak with a healthcare provider first. Be sure to mention other health conditions you have, as well as any medications and supplements you’re taking.
A healthcare provider or pharmacist can help you decide if CBD is right for you and possibly suggest a starting dose. All CBD products are not alike. If you’re purchasing CBD online, make sure it’s a reliable source and you have access to a COA. And, of course, stay away from products that claim to prevent or cure RLS.
Frequently Asked Questions
It varies a lot from person to person. It could be several hours to a full day. Factors such as metabolism, dose, method of administration, and how often you use it all play a role.
While there are anecdotal reports of improvement and even some of total remission, there’s not enough scientific data to put a number on it.
It appears that most people are able to tolerate CBD with minimal side effects. But it’s important to remember that research on dosing, administration, and cumulative effects is in its infancy.

The Effects of CBD Oil on Restless Leg Syndrome
Restless leg syndrome (RLS) affects up to 10 percent of the U.S. population, causing people to lose sleep due to uncontrollable spasms in the legs when trying to rest. If you suffer from RLS, you may find temporary relief by moving your legs in an attempt to stop the cramping and tingling feelings in your legs. Unfortunately, those unpleasant symptoms do not go away, and you’re left feeling tired during the day due to a lack of restful sleep.
Because the probable causes of RLS cover a wide range of conditions — everything from an iron deficiency and a low level of dopamine in the brain to varicose veins — remedies are hard to come by. Yet a small number of studies and anecdotal reports suggest CBD oil might help you alleviate the uncomfortable sensations of RLS and swollen varicose veins.
How CBD Oil Works on RLS
Cannabidiol, or CBD, is found in the cannabis plant along with tetrahydrocannabinol (THC). Both substances interact with the body’s endocannabinoid system, which regulates our perception of certain physiological sensations, such as mood, hunger, energy level, pain, and sleep, among many others. The difference between CBD and medical marijuana is that CBD oil is most often derived from industrial hemp, which contains a higher amount of cannabidiol, but doesn’t contain THC, the psychoactive agent that creates a feeling of euphoria in the user. That’s why you’re able to buy CBD oil in retail stores.
In recent years, medical cannabis has been approved by many states to treat a variety of conditions, including chronic pain and inflammation. For RLS patients, CBD oil’s main benefit is its relaxing effect, which eases a person into a restful sleep. That conclusion is supported by a recent study, which reports RLS patients experiencing a reduction in symptoms after taking cannabis.
CBD oil is not a cure for RLS; it merely alleviates some of the painful side effects of the condition. If you believe you suffer from RLS, you’ll need a full diagnostic review to determine what may be causing it. RLS has been attributed to several medical conditions, including iron deficiency, kidney disease, diabetes, and Parkinson’s disease. It could also be due to medications you take, such as antidepressants and anti-nausea medications. If you have one of those conditions, you’ll be prescribed dopamine agents to boost dopamine levels in the brain, iron supplements, or another medication to treat that condition.
Varicose Vein Treatment for RLS
Another possible cause of your RLS could be varicose veins. Varicose veins and RLS share many symptoms, including pain and cramping in the legs. Studies have suggested a connection between RLS and varicose veins. According to the research, when people with both RLS and venous insufficiency were treated for varicose veins, RLS symptoms greatly diminished.
Similar to its calming effect on RLS patients, CBD oil might reduce the discomfort and inflammation caused by varicose veins. If you don’t want to use CBD or medical marijuana, you can try hemp oil, which contains neither CBD or THC. It instead contains omega-3 fatty acid that thins blood as it runs through veins. Varicose veins develop when blood becomes blocked in the veins due to malfunctioning valves. Any substance that increases the speed of blood flow aids in circulation, decreases swelling, and reduces the appearance of varicose veins.
CBD can be taken before bed either orally or topically. Start with a low dose, and of course, check with your doctor first to ensure it doesn’t interfere with other medications you may be prescribed.
However, if you’re looking for a more permanent solution to your painful varicose veins and RLS, you’ll need a noninvasive treatment to collapse or remove the damaged vein. CBD oil, while typically not harmful, provides only a brief respite from varicose vein or RLS symptoms – it’s not a cure.

Restless legs syndrome: The benefits of CBD
Restless legs syndrome (RLS) or Willis-Ekbom disease is a neurological disorder characterized by an uncontrollable urge to move the legs, especially at night. In North America and Eastern Europe, it is estimated that 4-29% of the population is affected by this disorder, which severely affects the quality of life of sufferers. Currently, there is no official treatment or cure for RLS. As a general rule, doctors recommend a healthier lifestyle, possibly with medication to reduce stress and ease pain. However, these medications are restrictive, as they cause side effects and do not really solve the underlying problem. For some people, CBD (cannabidiol) is a natural alternative that improves their condition day and night.
Recent clinical research indicates that CBD helps relieve many of the symptoms of RLS, while improving the quality of sleep for patients who often suffer from insomnia. With CBD, they can finally have productive days and peaceful nights.
What are the positive effects of CBD on RLS? How to properly consume CBD to relieve the symptoms of this neurological disorder, in what form and at what dosage? To fully understand how CBD works on RLS, let’s start by looking at the elements that characterize this condition.
What is restless legs syndrome?
Restless legs syndrome, also known as Willis-Ekbom disease, is a neurological disorder that can occur at any time in your life. Symptoms tend to occur at night, when your body is at rest, making it especially difficult to sleep. Automatically, lack of sleep can have a serious impact on your quality of life.
For most RLS sufferers, symptoms include itching and tingling in the legs that causes involuntary movements. All this restlessness prevents them from sleeping and leads to a feeling of intense fatigue during the day. A vicious circle that does not give patients a single second of respite.
Pain, discomfort, lack of sleep. All these negative aspects affect the physical and psychological well-being of patients. To relieve their symptoms, many people feel the need to move around nervously, which will naturally increase their level of stress and anxiety on a daily basis. Common situations such as going to class or staying for dinner can become embarrassing and impact their social life. Because of this, it’ s important to change habits and learn how to manage stress to get rid of this disorder, and this is where CBD comes in.
What are the benefits of CBD to combat RLS?
Scientific studies from 2017 have revealed the positive impact of therapeutic cannabis on RLS symptoms. On the one hand, it improves quality of life during the day by calming nervousness. On the other hand, it soothes itching and nighttime discomfort that prevents sleep, while providing patients with quality, restorative, and deep sleep. According to the study, 5 out of 6 participants confirmed a total remission following a treatment exclusively based on cannabis. On the other hand, all participants noted a significant improvement of their sleep at the end of the treatment.
As this study was carried out on only a few people, one can wonder if these results are valid for all patients. For the researchers, if CBD is so effective to fight against RLS, it is in particular thanks to its positive effects on the production of dopamine, also called the hormone of happiness. Indeed, RLS is caused by a neurological disorder, itself caused by a dopamine imbalance. Therefore, taking CBD helps the brain to stimulate this neurotransmitter and regulate it in a completely natural way.
Furthermore, scientists are unanimous in saying that CBD interacts with the endocannabinoid system and offers a whole host of therapeutic virtues that can soothe pain and effectively reduce stress. Thanks to its anti-anxiety properties, hemp allows for a lighter, calmer, and more serene mind. That’s why RLS sufferers who take CBD before bed are finally able to find sleep, rest, and have a great day.
How to consume CBD to relieve the symptoms of RLS?
Typically, RLS sufferers take CBD oil orally or sublingually to relieve their symptoms. To enjoy the relaxing effects for a few hours, you can pour a few drops on your food or in your drinks. If you prefer a fast-acting, but shorter-lasting effect, you can pour a few drops of CBD oil directly under your tongue.
CBD flowers and resins
With CBD flowers and resins, the scents and flavors are all there. To consume them in a healthy way, you can use a vaporizer, or crumble them to incorporate them in your dishes or in your herbal teas. The advantage of vaporization is that the effects will be almost instantaneous and all the flavors of hemp will be perfectly preserved. If you choose to incorporate them in your culinary preparations, the relaxing effects will take longer to appear, but they will last effectively for a few hours.
If you don’t like the taste of hemp and prefer a neutral product to get the benefits of medical cannabis, you may well turn to CBD capsules. These edible capsules have no taste or smell, but have the same soothing effects as oil or resin. Plus, the small capsule boxes are easy and discreet to carry around on a daily basis.
How much CBD should I take to relieve RLS symptoms?
With CBD, there is no risk of overdosing, but there is no perfect dosage either. If you suffer from RLS, you should adjust the dosage according to the intensity of your pain and how you feel. Start with a low dose to see if it does much for you or not. If you feel that you need more, increase the doses gradually. If in doubt, ask your doctor or a pharmacist for advice, who will be able to guide you towards the most suitable dosage for you. Once again, it is important to remember that CBD is not a medicine and that it cannot replace a real medical follow-up. Sometimes, CBD is enough on its own. But in some cases, it can be used in addition to a medical treatment. Whatever the case, listen to your body and choose the CBD format that suits you best.
Can CBD permanently cure RLS?
No, CBD is not a medicine and it does not cure any disease. On the other hand, it can help relieve many symptoms and restore a better quality of life. In other words, it helps you get back to quality sleep, reduce stress and anxiety and thus, it accompanies you in a gentle and totally natural healing process.
Can CBD cause neurological side effects?
No, CBD is not known to cause neurological side effects, unlike some drug treatments. In fact, CBD is a natural substance that has powerful protective properties for the brain and neurons.
