Over the years, CBD oil has skyrocketed in popularity, and because of that, a wealth of new brands have flooded the market. Sadly, not all brands are created equal. Many of today’s brands are not the best quality, and therefore, will not be effective against anxiety, depression, and stress.

But which brands rise to the top in today’s competitive CBD oil market? Read below to discover our top five picks.

Our Top 5 CBD Oils for Anxiety & Depression

  • FAB CBD Oil: Best Quality and Most Potent
  • CBDistillery: Known Product Diversity
  • NuLeaf Naturals: High Product Potency
  • cbdMD: Broad Spectrum Products
  • Green Roads: Different Variety Products

How We Created Our CBD Oil for Anxiety List

The CBD oil industry is enjoying a steady rise in popularity. Sadly, with that popularity came an insurgence of inferior brands. While there are many reputable brands out on today’s market, there are also quite a few who are only interested in turning a quick profit.

Many of those inferior brands use a low-quality CBD extract that’s not only ineffective, but that’s also laden with dangerous chemicals, pesticides, herbicides, and solvents. Therefore, it’s highly important to put some time into researching every brand that you’re interested in.

We spent countless hours researching some of the top CBD oil brands on today’s market in order to help take some of the guesswork out of the process for our readers. We also spent quite a bit of time pouring over scientific studies so that we could best inform you exactly how CBD oil works to help with anxiety, depression, and stress.

When it came to putting our findings forth to our readers, we simply wanted to present them with solid facts and information that was free of sensationalism, embellishment, and hype.

In choosing our top CBD oils for anxiety, depression, and stress, we looked closely at:

  • Quality and Source of Hemp: As you might expect, organic hemp sources are the best way to go. And while many places around the world grow hemp, not all hemp is grown according to the same standards. Therefore, brands that locally source their hemp have more control over its quality.
  • Extraction Process: CBD can be extracted in a great number of different ways. Currently, the cleanest and best method is the Co2 extraction process. Other methods can and do leave dangerous chemicals in the extract. Co2 extraction results in extracts that are safe and pure.
  • Full-Spectrum, Broad Spectrum, or CBD Isolate: Some brands offer full-spectrum products while others offer broad spectrum or CBD isolates. Full-spectrum and broad spectrum options contain beneficial terpenes, cannabinoids, vitamins, and nutrients, while isolates solely contain pure CBD. Unlike full-spectrum products, broad spectrum products and CBD isolates do not contain any THC. According to law, full-spectrum CBD products can only have less than 0.3% THC.
  • Independent Third-Party Lab Tests: The best brands will always take on an independent third-party laboratory to test its products. These labs test and certify CBD oils for potency, purity, and quality. Third-party lab results show customers that a brand is committed to creating top quality products.
  • Oil Potency: CBD oils come in different strengths and potencies. Some oils are stronger and more potent than others. These types of CBD oils are typically used by people who have difficult health issues that they are trying to tackle.
  • Brand Reputation: In looking at brand reputation, we zeroed in on how transparent the brand was with its customers as well as the brand’s overall reputation among its customers. In looking at brand reputation, we also took into account the quality of the brand’s customer service.
  • Price: In looking for a top-quality CBD oil, many customers also want to get the best value available. Therefore, we spent quite a bit of time focusing on the amount of CBD customers receive based on the amount of money they’re spending on a product.

In looking at all of our criteria, you can clearly see that our list is quite extensive. We spent a great deal of time and effort coming up with our top five CBD oil brands for anxiety, depression, and stress, and in the end, it was well worth it if we are able to help our readers choose a top-quality, reputable CBD oil brand that best suits their needs.

CBD Oil for Anxiety, Depression

FABCBD_FEB2020_SET2-05

According to the Anxiety and Depression Association of America , anxiety is one of the most common types of mental illnesses in the United States. To date, over 40 million adults aged 18 and older struggle with anxiety disorders. The good news is that anxiety, depression, and stress are extremely treatable.

Some of the more common symptoms associated with anxiety disorder are shortness of breath, panic, feelings of helplessness, excessive sweating, and a racing heart. And while there are many options of treatment available that include regular exercise, eating a nutritionally sound and balanced diet, getting adequate amounts of sleep every night, and using methods such as meditation and yoga to help alleviate stress, many people still have a difficult time managing.

Since some of the prescription medications prescribed for anxiety, depression, and stress can be harsh or dangerous, more people are looking for safe, alternative methods to help treat the symptoms associated with anxiety and depressive disorders. The good news is that many studies have shown that CBD may be effective in the fight against these disorders.

In fact, full-spectrum oils help to calm anxiety by quieting a racing mind as well as reducing chronic pain. Likewise, CBD oil helps combat depression though its anti-stress properties. Encouraging research studies have found that while it can take antidepressants weeks to take effect, the calming effects of CBD are felt almost immediately. On top of that, CBD’s effects last longer and have fewer side effects than prescription antidepressants.

Stress is another dangerous condition because if left unchecked, it can cause many unwanted and deadly health issues including:

  • Fatigue
  • Weight Gain
  • Heart Disease
  • High Blood Pressure
  • Depression
  • Muscle Tension
  • A Weakened Immune System
  • Anxiety
  • Digestive Issues and Ulcers

While living through an occasional stressful situation is to be expected, chronic stress can take a serious toll on the body. Moreover, elevated levels of cortisol, (the stress hormone) in the brain can severely affect learning, memory, and cognition.

Much like anxiety and depression, multiple studies have shown that CBD can also help to quell many of the symptoms listed above.

How CBD Works to Help Alleviate Issues Related To Anxiety Disorders

The biggest impact that CBD has on depression and anxiety disorders is that it helps to promote relaxation. When endocannabinoid receptors in the body respond to CBD, a natural relaxation of the mind and body takes place.

There are specific receptors within the body that help to control serotonin levels . As healthy levels of serotonin levels are maintained, mood, energy, and overall stress levels will be greatly improved. Therefore, it’s important to maintain steady levels of serotonin in the body so that you can feel happier and more relaxed overall.

What is the Best Dosing for CBD for Anxiety?

Just like with any supplement or prescription medication, proper dosing of CBD is important as well. Before we begin discussing how to find your best dose, please remember that everyone’s body is different. So, a dose that might work well for you might not work as well for someone else. Also, mid-range doses have more benefits than higher or lower doses.

In beginning a CBD health regimen, you should begin low and increase slowly. A great place to begin is by taking a ½ a dropper full of CBD oil (roughly 5mg) once a day for a week. After a week, check in with yourself to see how you are feeling. If you feel that you are good where you’re at, then stay where you are. However, if you feel that more CBD is needed, then it’s time to increase the dose.

When you increase your dose, the next step is to go to 5mg of CBD twice a day for a week. After another week, go ahead and reassess. Then, if you feel so inclined, increase the amount of CBD as needed.

It’s important to know that you cannot overdose on CBD. Having said that, the body still needs an ample amount of time to get used to both the CBD as well as the dosing. So be patient and enjoy the journey!

Can CBD Oil for Anxiety Be Legally Purchased?

The quick answer to this question is, yes. The longer explanation is that it is legal to purchase CBD online as long as it was made from hemp and has less than 0.3% THC in it.

Closing Thoughts: Should You Use CBD Oil for Anxiety?

If you’ve been grappling with depression or anxiety disorders or chronic stress, then CBD oil might be a great way to introduce a safe, natural, effective remedy into your life. Moreover, CBD is a fantastic alternative to dangerous and sometimes addictive prescription medications.

Regardless of whether you suffer from anxiety, depression, or stress, you should put some serious thought into making CBD oil a regular part of your natural healthcare regimen. If you are confused as to where to begin, why not start by selecting some products from the top five brands profiled in this article. FAB CBD is an amazing brand to go with because in our research, we found that the FAB CBD is involved from seed to sale in the creation of all of its products. Additionally, FAB CBD’s full-spectrum oils are clean, potent, pure, and highly effective. Not to be outdone, but cbdMD came in as a solid second place.

While prescription medications for anxiety, depression, and stress can take weeks before the full effects can be felt, the calming effects of CBD can be felt almost immediately. If you have any questions or concerns about starting a CBD regimen, never hesitate to talk with your primary care physician or specialist.

Best CBD Oil for Anxiety, Depression and Stress – Top 5 Brands in 2021

CBD has a host of calming benefits associated with it. And, regularly incorporating it into your lifestyle will allow you to reap all of those many benefits. If you’ve been struggling with anxiety, depression, or stress, now’s the time to take advantage of the healing power of CBD.

A number of studies have shown that CBD oil is highly effective in treating anxiety, depression and stress in a host of beneficial ways.

CBD Oil for Depression, Schizophrenia, ADHD, PTSD, Anxiety, Bipolar & More

You can extract more than 70 different components from a marijuana plant, technically known as cannabis sativa. Two of the most common constituents are delta-9-tetrahydrocannabinol (known colloquially as THC) and cannabidiol (CBD).

Because CBD is not as regulated as THC (though it may be technically illegal under federal laws), nor does it provide any accompanying “high” as THC does, it has become increasingly marketed as a cure-all for virtually any ailment. You can now find CBD oil products online to treat everything from back pain and sleep problems, to anxiety and mental health concerns.

How effective is CBD oil in the treatment of mental disorder symptoms?

Unlike it’s sister THC, CBD doesn’t have any of the associated negative side effects of tolerance or withdrawal (Loflin et al., 2017). CBD is derived from the cannabis plant, and shouldn’t be confused with synthetic cannabinoid receptor agonists like K2 or spice.

Because of its relatively benign nature and more lax legal status, CBD has been more widely studied by researchers in both animals and humans. As researchers Campos et al. (2016) noted, “The investigation of the possible positive impact of CBD in neuropsychiatric disorders began in the 1970s. After a slow progress, this subject has been showing an exponential growth in the last decade.”

Research has shown that CBD oil may be effective as a treatment for a variety of conditions and health concerns. Scientific studies demonstrate the effectiveness of CBD to help relieve some of the symptoms associated with: glaucoma, epilepsy, pain, inflammation, multiple sclerosis (MS), Parkinson’s disease, Huntington’s disease, and Alzheimer’s. It appears to help some people with gut diseases, such as gastric ulcers, Crohn’s disease, and irritable bowel syndrome as well (Maurya & Velmurugan, 2018).

You can find low-end and high-end CBD oil products. The most popular CBD oil product on Amazon.com retails for around $25 and contains only 250 mg of CBD extract.

In a pilot randomized placebo-controlled study of adults with attention deficit hyperactivity disorder (ADHD), a positive effect was only found on the measurements of hyperactivity and impulsivity, but not on the measurement of attention and cognitive performance (Poleg et al., 2019). The treatment used was a 1:1 ratio of THC:CBD, one of the common CBD treatments being studied along with CBD oil on its own. This finding suggests more research is needed before using CBD oil for help with ADHD symptoms.

Anxiety

There are a number of studies that have found that CBD reduces self-reported anxiety and sympathetic arousal in non-clinical populations (those without a mental disorder). Research also suggests it may reduce anxiety that was artificially induced in an experiment with patients with social phobia, according to Loflin et al. (2017).

Depression

A review of the literature published in 2017 (Loflin et al.) could find no study that examined CBD as a treatment for depression specifically. A mouse study the researchers examined found that mice treated with CBD acted in a way similar to the way they acted after receiving an antidepressant medication. Therefore, there is virtually little to no research support for the use of CBD oil as a treatment for depression.

Sleep

Loflin et al. (2017) only found a single CBD study conducted on sleep quality:

Specifically, 40, 80, and 160 mg CBD capsules were administered to 15 individuals with insomnia. Results suggested that 160 mg CBD was associated with an overall improvement in self-reported sleep quality.

There are two human trials currently underway that are examining the impact of both THC and CBD on post-traumatic stress disorder (PTSD) symptoms. One is entitled Study of Four Different Potencies of Smoked Marijuana in 76 Veterans With PTSD and the second is entitled Evaluating Safety and Efficacy of Cannabis in Participants With Chronic Posttraumatic Stress Disorder. The first study is expected to be completed this month, while the second should be completed by year’s end. It can take up to a year (or more) after a study has been completed before its results are published in a journal.

Bipolar Disorder & Mania

The depressive episode of bipolar disorder has already been covered in the depression section (above). What about CBD oil’s impact on bipolar disorder’s manic or hypomanic episodes?

Sadly, this has not yet been studied. What has been studied is cannabis use on the effect of bipolar disorder symptoms. More than 70 percent of people with bipolar disorder have reported trying cannabis, and around 30 percent use it regularly. However, such regular use is associated with earlier onset of bipolar disorder, poorer outcomes, and fluctuations in a person’s cycling patterns and severity of manic or hypomanic episodes (Bally et al., 2014).

More research is needed to see whether supplementing CBD oil might help alleviate some of the negative impact of cannabis use. And additional research is needed to examine whether CBD oil on its own might provide some benefits to people with bipolar disorder.

Schizophrenia

Compared to the general population, individuals with schizophrenia are twice as likely to use cannabis. This tends to result in a worsening in psychotic symptoms in most people. It can also increase relapse and result in poorer treatment outcomes (Osborne et al., 2017). CBD has been shown to help alleviate the worse symptoms produced by THC in some research.

In a review of CBD research to date on its impact on schizophrenia, Osborne and associates (2017) found:

In conclusion, the studies presented in the current review demonstrate that CBD has the potential to limit delta-9-THC-induced cognitive impairment and improve cognitive function in various pathological conditions.

Human studies suggest that CBD may have a protective role in delta-9-THC-induced cognitive impairments; however, there is limited human evidence for CBD treatment effects in pathological states (e.g. schizophrenia).

In short, they found that CBD may help alleviate the negative impact of a person with schizophrenia from taking cannabis, both in the psychotic and cognitive symptoms associated with schizophrenia. They did not find, however, any positive use of CBD alone in the treatment of schizophrenia symptoms.

Improved Thinking and Memory

There is little to no scientific evidence that CBD oil has any beneficial impact on cognitive function or memory in healthy people:

“Importantly, studies generally show no impact of CBD on cognitive function in a ‘healthy’ model, that is, outside drug-induced or pathological states (Osborne et al., 2017).”

If you’re taking CBD oil to help you study or for some other cognitive reason, chances are you’re experiencing a placebo effect.

CBD Summary

As you can see, CBD research is still in its early stages for many mental health concerns. There is limited support for the use of CBD oil for some mental disorders. Some disorders, including autism and anorexia, have had little research done to see whether CBD might help with the associated symptoms.

One of the interesting findings from research to date is that the dosing found to have some possible beneficial effects in research tends to be much higher than what is found in products typically sold to consumers today. For instance, most over-the-counter CBD oils and supplements are in bottles that contain a total of 250 to 1000 mg.

But the science suggests that an effective daily treatment dose might be anywhere from 30 to 160 mg, depending on the symptoms a person is seeking to alleviate.

This suggests that the way most people are using CBD oil today is not likely to be clinically effective. Instead, at doses of just 2 to 10 mg per day, people are likely mostly benefiting from a placebo effect of these oils and supplements.

Before starting or trying any type of supplement — including CBD oil or other CBD products — please first consult your prescribing physician or psychiatrist. CBD may interact with psychiatric medications in a way that is unintended and could cause negative side effects or health problems.

We also do not really understand the long-term effects and impact of CBD oil use on a daily basis over the course of years, as such longitudinal research simply hasn’t yet been done. There have been some reported negative side effects experienced in the use of cannabis, but it’s hard to generalize such research findings to CBD alone.

In short, CBD shows promise in helping to alleviate some symptoms of some mental disorders. Much of the human-based research is still in its infancy, however, but early signs are promising.
