Bipolar Disorder & CBD Oil: Potential to Help with Depressive Episodes

The depressive episodes of bipolar disorder can be extremely debilitating. Could CBD oil help restore balance?

Awareness surrounding mental health conditions like bipolar disorder is on the rise but even with this increase in knowledge and understanding, finding suitable treatment can be elusive. While it is more widely known for its pain relieving, anti-inflammatory properties, CBD oil is now being researched for its potential benefits for treating mood disorders.

Categorized by cyclical peaks and troughs of extreme moods referred to as manic and depressive episodes, bipolar disorder will affect 4.4% of people within their lives. While manic episodes can result in inappropriate behaviors, impulsivity, and insomnia, depressive episodes render the patient feeling hopeless, worthless, and even suicidal.

The most common bipolar treatments involve pharmaceuticals, but using CBD oil for bipolar disorder may be an option worth exploring.

Effectiveness of CBD Oil for Bipolar Disorder

While no clinical trials on the links between bipolar disorder and the use of cannabinoids currently exist, a review on the topic suggested that based on what we do know, “cannabidiol (CBD) may exert sedative, hypnotic, anxiolytic, antidepressant, antipsychotic and anticonvulsant effects.”

Already known to improve mood and reduce depression, CBD oil may also be used to control the presentation of bipolar disorder through its effects on the endocannabinoid system. Phytocannabinoids like tetrahydrocannabinol (THC) and cannabidiol (CBD), are the plant equivalent of the endocannabinoids naturally produced by your body’s endocannabinoid system. Cannabinoids, whether produced by cannabis or your body, are able to affect CB1 and CB2 receptors both directly and indirectly.

Multiple studies have linked irregularities in the endocannabinoid system with mental illness, suggesting that CBD oil may help. One such study was conducted in Italy that looked at the CB1 receptor in patients who had major depression or bipolar disorder, as well as a healthy test group. While the results were not significant enough to draw a definitive conclusion, the report stated that differences in the endocannabinoid system “may contribute to the susceptibility to mood disorders.” CBD works in a way that elevates the number of endocannabinoids in the system to reach homeostasis, which could present a healthier mental state.

Further studies on animal populations have linked a dysfunctional endocannabinoid system to lower serotonin levels, and it is also believed that low serotonin levels are linked to bipolar disorder. CBD is able to elevate serotonin levels in the brain by acting on the 5-HT1A serotonin receptor. Through this action, CBD oil could be useful for addressing certain mood disorders by balancing the endocannabinoid system and also help reduce the depressive symptoms of bipolar disorder.

Unfortunately, CBD did not show the same promising impact on manic episodes.

In one review, researchers examined the effects of CBD on two patients with bipolar affective disorder. Both bipolar patients were given a placebo for the first 5 days of study and CBD for days 6-30. On days 6-20, the first patient was also given a dose of olanzapine. On day 31, CBD was discontinued and both were given a placebo for 5 more days. The first patient, who was also administered olanzapine, showed improvement in her symptoms while taking both medicines together and experienced no improvement during the placebo and CBD trials. The second patient experienced no symptom improvements.

So, it appears CBD oil may hold the most potential for treating the depressive side of manic depressive swings.

Benefits of Using CBD Oil for Bipolar Disorder

Unfortunately, most treatments for bipolar disorder are not totally effective. While prescription drugs in combination with psychotherapy are able to help a large number of people, there are many others who find their condition is resistant to treatment.

While CBD oil is gaining traction in medical circles for its use in treating mental illness, the most common medications prescribed to patients with bipolar disorder are still antidepressants, mood stabilizers, and antimanic drugs.

Research has shown that antidepressants can actually increase the likelihood of mania and/or rapid cycling, which is why mood stabilizers are often prescribed in conjunction with these medicines. This cocktail of medications, while effective for some, leaves others with a host of additional side effects to contend with on top of their condition, as outlined in the chart below.

If you’re considering adding CBD oil to your bipolar treatment regimen, it’s extremely important that you talk to your doctor and keep the potential drug interactions outlined in the chart below in mind.

How to Take CBD Oil for Bipolar Disorder

If you’re unhappy with the way that you are currently treating your bipolar disorder, it is worth speaking to a medical professional to see if CBD oil could help.

While it is generally well tolerated, CBD oil can interact with some medications, including antidepressants, so it’s imperative that you seek medical advice first.

CBD Oil Dosage for Bipolar Disorder

There is no one size fits all solution when it comes to CBD oil dosages. What works for one person will not be what works for another. It is recommended that you begin with the lowest recommended dose for your CBD oil product and slowly increase the dosage if needed.

If you’re looking for a starting point of reference, and your CBD oil product does not have a recommended dosage, we have come up with the following serving suggestion after reviewing hundreds of CBD products:

The CBD Oil Review Serving Standard is 25 mg of CBD, taken twice daily.

If this amount does not provide the results you need, slowly increase the amount by 25mg every 3 to 4 weeks until the desired effects are achieved.

To learn more about dosage, read our CBD Oil Dosage Guide or consider speaking to a naturopathic doctor who can provide you with the most personalized action plan.

CBD Delivery Format

There are lots of different ways to take CBD oil for bipolar disorder. Most people will choose a format that is comfortable and familiar to them, like vaping CBD or using a CBD oil capsule. Each format has its advantages that must be factored into the decision.

CBD Vape Oil/CBD Flower:  These inhaled delivery formats are fast acting. Because the CBD is absorbed directly through the lungs and does not have to be processed through the liver, you’ll feel the effects immediately. The primary downside is that the effects often wear off within an hour. It can also be difficult to gauge dosage because an inhale can vary from person to person. Using a CBD oil vape or CBD flower is best for treating the onset of sudden symptoms, like anxiety or depressive thoughts.

CBD Oil Capsules/Edibles:  CBD oil capsules and edibles are an incredibly easy and convenient way to take CBD. CBD capsules provide the same dose every time and can be consumed in a very familiar way, with your daily vitamins, for example. Because the CBD has to pass through the digestive system and is then absorbed through the liver, it can take up to an hour for the effects to appear. But, these effects can last 4 to 6 hours, making a CBD capsule or edible a perfect“set it and forget it” method for taking your CBD—these delivery formats are great for a regular and consistent supplementation routine.

CBD Oil Tinctures/Drops:  CBD oil drops and tinctures are great for people looking for maximum dose control. They are administered through a dropper making it easy to adjust up or down as needed, down to the very drop! The CBD is is absorbed through the skin under the tongue and the effects can be observed within 30 minutes and can last 2 to 4 hours. Tinctures and drops are great for both regular CBD oil supplementation and discreet use for sudden symptoms.

Give yourself some time to experiment with the different delivery formats. You may find one is better for addressing your bipolar symptoms than others. For more, check out our Beginner’s Guide to CBD Oil for an in-depth look at the different types of CBD oil products on the market.
