What is GABA?
GABA (Gamma-Aminobutyric acid) is a naturally occurring amino acid that works as a neurotransmitter, facilitating communication among brain cells. It is one of the most abundant neurotransmitters in the brain; in fact, over 40% of neurons have a GABA receptor. The primary role of this amino acid is to slow the activity of neurons in the brain and central nervous system. This process helps our brain shift into a lower gear and bring about more relaxation and calm.
How to Increase GABA Levels
Research shows a link between low levels of GABA and increased anxiety, high blood pressure and insomnia. These findings indicate that a GABA deficit is possible and balancing your GABA levels is vital to good health.
Can you get GABA naturally from food?
GABA isn’t readily available in natural food products. However, some fermented products, including yoghurt and kefir, contain the amino acid. Alternatively, some foods contain a substance called flavonoids, which influence how GABA works in the brain.
These products include:
- Green, black and oolong teas
- Red wine
What are flavonoids?
Flavonoids are a naturally occurring compound and are rich in antioxidant activity. A diet rich in flavonoids will assist your body in fighting off everyday toxins and decrease the risk of some chronic health conditions. The flavonoids in some foods will activate the GABA receptors and help regulate your body.
GABA as a supplement
GABA is also available as a supplement to treat anxiety, high blood pressure, pain-related issues and sleep problems. However, when taken alone, GABA supplements struggle to penetrate the blood-brain barrier. Consequently, this means that only a small amount of the supplement may make it to your brain and will have little effect. For the most effective results, researchers recommended taking an enhanced GABA supplement that does not inhibit the GABA receptor.
What is CBD?
CBD, also known as cannabidiol, is one of over one hundred compounds that come from the cannabis plant. Unlike its cousin, THC (Tetrahydrocannabinol), CBD is non-psychoactive and will not have intoxicating effects.
The cannabis plant goes through an extraction method to release the CBD and make it safe for consumption. It is then combined with a carrier oil, such as MCT or olive oil, to form the CBD oil you see on the market.
Will CBD get you High?
The short answer – no, CBD will not get you high.
One of the most common misconceptions around CBD is its ability to cause a ‘high’. The confusion stems from its association with the cannabis plant. In fact, cannabidiol comes from the hemp variation of the cannabis strain but does not have psychoactive abilities. Therefore, when CBD gets extracted from the plant, the intoxicating component, THC, gets removed. The varying extraction methods will affect the quality of the final product and how much THC is left. Considering this, we recommend looking for a company that is transparent about its CBD extraction process.
The quality and contents of CBD oil will differ from where you buy it, however, here at ULU, we guarantee our products contain less than 0.0005% of THC – virtually zero, hence why we pride ourselves on our premium quality.
The Different Types of Cannabidiol
As with the extraction process, different types of cannabidiol can affect the end product. If your product contains high levels of THC; it could work against the GABA receptors in your body and inhibit it, which will lead to little improvement in your sleep. Consequently, it’s essential to do your research about the type of CBD you’re taking and the extraction methods available.
CBD isolate is the purest form of cannabidiol and an ideal type for first-time buyers. Products with CBD isolate will not contain any of the other beneficial cannabinoids. This type of CBD is also an excellent option for anyone who has to take a drug test, such as professional athletes.
In full-spectrum CBD, the whole plant gets extracted, meaning it contains all of the natural cannabinoids and terpenes found in the hemp plant. With full-spectrum, you will be able to taste and smell the hemp. Lastly, this variation is a good option for amino acid and GABA supplements because the flavonoids in the hemp plant are still present and activate the GABA in our brains.
Sitting in between full-spectrum and isolate, broad-spectrum CBD has trace elements of other beneficial cannabinoids (CBDa and CBG) but only a mild taste of the hemp plant.
How to take CBD?
CBD products come in many different forms, and depending on what you need it for, you may need a specific product.
Some CBD forms include:
- Bath bombs
- Topical treatments (such as creams and muscle rubs)
If you’re looking to treat sleep difficulties, our CBD and GABA oil is the best option for you because of its ability to enter the bloodstream and pass through the blood-brain barrier.

5 Reasons Why CBD and GABA Can Promote Better Sleep
Now you know what GABA and CBD are, we will explore how these two potent compounds interact with our body to assist sleep.
1. CBD is a Natural Sleep Aid
Cannabidiol is a natural sleep aid because of the way it interacts with our endocannabinoid system (ECS). The ECS is a complex cell-signalling system within our bodies that helps to regulate sleep, mood, and other bodily functions. Furthermore, our bodies naturally contain cannabidiol, so added CBD would improve the functions of our ECS and help restore balance and harmony in our body, allowing us to sleep easier.
Over the last few years, research has focused on how CBD affects sleep. In a study of 72 adults, 66.7% of patients reported improvements in their sleep within the first month. In addition, 79.2% of patients said their anxiety was reduced within the first month and remained low for the duration of the study. So in conclusion, CBD has been known to relax the mind and body and naturally aids sleep thanks to its ability to assist the ECS and balance our bodies.
2. GABA Helps you Fall Asleep Faster and Wake Up Refreshed
Research shows that higher levels of GABA put people in a non-REM state of rest for longer. This stage of sleep is known to use less energy and promotes calmer sensations such as slowed breathing and heart rate. Due to this change, participants reported a noticeable difference in their sleep. As a matter of fact, the increased time of non-REM sleep meant people would wake up feeling refreshed and energised. Moreover, the same study also demonstrated how quickly GABA gets absorbed into the body, hence it had a significantly strong effect on the early stages of sleep. Therefore, having added GABA supplements make it easier to fall asleep quicker.
3. GABA and its Affect on Blood Pressure
As our bodies prepare for sleep, there is a natural drop in blood pressure which helps us transition into rest. However, if you have a higher blood pressure than average, this can inhibit your ability to fall asleep and cause more sleep problems. Studies show GABA has a positive effect on this and can lower high blood pressure. Consequently, taking a GABA supplement will help in the progression to sleep and improve the quality of rest.
4. The Entourage Effect
There is an argument that when taking GABA supplements alone, they struggle to have a significant effect because it cannot break the blood-brain barrier and reach the brain. Despite that, when enriched with CBD, the abilities of both substances are enhanced, meaning that the added GABA can get to the brain and help promote better quality sleep.
When you’re looking for an enriched GABA supplement, make sure to do your research and choose one combined with pure CBD. If you’re taking a GABA supplement alongside a THC product, this can have the reverse effect and inhibit your GABA receptors. Instead of your supplement increasing your GABA levels, it will shut down your bodies ability to regulate stress and anxiety.
Here at ULU, we pride ourselves on our high-quality ingredients; that’s why we have a 0% THC guarantee and test our products with a third party, to give you complete peace of mind.
5. Reduces Anxiety and Presses the Pause Button on your Brain
When our brain goes into the stress response of ‘fight, flight, or freeze’, our brain produces a stress hormone called cortisol. When this process happens, it can negatively impact our bodies and minds – including our ability to fall asleep and stay asleep. After that, GABA and the GABA receptors in our bodies send a signal to your brain to stop the stress response and produce feelings of relaxation. It’s common for people with anxiety to have lower levels of GABA and not be able to regulate the stress response in a healthy way. Accordingly, when we experience higher levels of stress and low levels of GABA, this can lead to enhanced sleep problems.
The amino acid is also useful for calming our mind, especially when overstimulated with thoughts. When you reduce anxiety, it leads to improved sleep quantity and quality.
Where Can I Buy GABA Supplements for Sleep?
When treating conditions like insomnia, there are medications that you can take. However, these can come with substantial side effects such as hallucinations, which can negatively affect GABA levels. With supplements, you can safely increase your GABA levels and sleep better – they are ideal for helping you switch off before bed.
As we discussed earlier, some feedback shows taking GABA supplements alone are relatively ineffective. This ineffectiveness is due to the added GABA not being able to penetrate the blood-brain barrier, meaning only a small amount of the supplement will make it to your brain.
Nevertheless, GABA enriched with another component such as CBD, enhances its ability to break through that barrier and make it to the brain, resulting in a more reliable and effective product.
When these two powerful components are combined, you get a stronger boost and better sleep.
Here at ULU, we crafted a premium range of CBD and amino acid supplements, including our CBD and GABA oil. While GABA supplements aren’t new to the market, the combination of CBD and GABA supplements are relativity forthcoming.
Our CBD and GABA oil work to improve sleep thanks to its ability to reduce stress, pain, and enhance mental and physical performance. When combined, it creates an entourage effect . Meaning together the CBD and GABA have more substantial effects compared to being taken alone.

Should CBD Be Taken With Other Supplements?
With more supplements these days than ever before, it can be confusing to figure out which supplements are compatible with one another and which have adverse effects. We often hear individuals asking, do any supplements interact with CBD oil?
And while we always recommend checking with your doctor before adding any supplements to your wellness routine, we’ve compiled a list of trendy supplements and their known interactions with CBD oil.
MCT Oil & CBD
MCT stands for medium-chain triglyceride because it contains medium length chains of fats called triglycerides. Because of their shorter length, they are easier to digest than other longer chain fatty acids.
MCT oil is commonly extracted from coconuts because more than 50% of the fat in coconut oil comes from MCTs. However, these fats can also be extracted from other foods like palm and dairy products.
So what is the advantage of adding these MCTs to your routine? This natural, healthy fat may help support brain function, memory, and heart health – and who wouldn’t want that!
Where does CBD come into the equation? It is fat-soluble, meaning that it dissolves in oil rather than water. When we are thinking about the body, fat-soluble substances are better absorbed into the bloodstream when they are digested with fat.
For health-minded individuals, natural, healthy fats are the best option for this easier absorption. So how do you mix CBD and MCT oil for ultimate absorption? Well, you can go for a fun route, like adding MCT oil and CBD to Keto coffee, or you can go a more standard direction by opting for a CBD oil with a MCT carrier oil.
So in terms of interaction, MCT oil and CBD are a great pair, especially if you are looking for quick absorption and faster effects.
CBD + Valerian Root
If getting a good night’s sleep is your main concern, you have undoubtedly heard of all of the various aids for sleep – from meditation and supplements to tryptophan-rich foods and yoga poses. But with all of the recommendations and guarantees for sleep, it can get overwhelming.
By now, everyone has heard of the effects of CBD on sleep cycles. But perhaps Valerian Root is not so common. This ancient herb, known for its calming effects, contains a number of compounds that may help reduce stress and promote better sleep. So what about if we combined it with CBD?
While every body is different, the effects of CBD alongside valerian root has had marvelous results on restlessness and more restful sleep.
Because valerian root contains antioxidants that appear to have sedative and sleep-enhancing properties, it pairs quite nicely with CBD. And because CBD is known to influence the endocannabinoid system, which is responsible for all kinds of bodily functions (including sleep), taking CBD with valerian root may enhance the overall effects.
How? GABA is a neurotransmitter that inhibits or slows down the brain’s functions. When GABA steps in, it can present itself in the body as the feeling of relieving anxiety, reducing stress, and improving sleep. And while the brain naturally releases GABA at the end of the day to help you get to sleep, valerian root and CBD are both known to affect GABA levels and get you to dreamland even more seamlessly.
However, be sure to check with your doctor, as not all groups should take valerian root, including: individuals with liver disease, women who are pregnant or breastfeeding, and children under 3 years old. And as a disclaimer: unlike its lovely scented flowers, valerian root has a strong earthy odor, so it may be a good idea to opt for a capsule with valerian root powder to forgo the scent!
Or even better, a capsule with both CBD and valerian root for even better rest and relaxation!
CBD + L-theanine
L-theanine is a nootropic or, in other words, a supplement used commonly to enhance memory or other cognitive functions. L-theanine is believed to encourage wakeful relaxation without making you sleepy.
By influencing chemical messengers in the body like serotonin and dopamine, which influence mood, sleep, and emotion, L-theanine may help support normal stress response, focus, and memory in healthy individuals.
How does L-theanine interact with CBD and what are the benefits of taking them together? As mentioned before, it is believed that CBD helps to balance the body’s endocannabinoid system to help it naturally manage stressors like anxiety, sleeplessness and physical pain. While L-theanine is hard at work to support better mental focus, CBD can calm the mind and body, giving you the best of both worlds. For this reason, L-theanine and CBD seem to pair very well together for increased clarity and calm.
What about L-theanine, CBD, and Ashwagandha?
Now if you are wondering about L-theanine and CBD together, you may be privy to the supplement world in general and wonder: can I take L-theanine, CBD, and something like Ashwagandha together?
The easy answer: yes! However, time of day is really key to unlocking the most of these three supplements together.
Classified as an adaptogen, or an herb believed to help the body resist physical and mental stress, ashwagandha has been for centuries for helping calm the mind and body. It has also been used to help boost brain function, while promoting a sense of calm for the body and mind.
Because ashwagandha is commonly known for its help with stress response and maintaining calm, it is a good idea to take this supplement before bed to help you fall asleep. Which begs the question: when should you be taking L-theanine and CBD?
Cannabidiol (CBD) is quite versatile in its usage, as it can be taken in different dosages at all times of day. When taken in higher doses, it is believed to help with rest and sleep. When taken in lower doses, CBD can simply support a sense of calm when taking care of everyday activities, and even provide a little boost of focus. Basically, CBD can be taken whenever you need a little extra calm.
So where does L-theanine fit into the equation?
Being the nootropic it is, L-theanine is probably better suited for the morning time. Because it evokes mental clarity, you can take L-theanine alongside your morning cup of coffee and morning dose of CBD, and leave ashwagandha for later in the day (with a higher dose of CBD).
Supplement stacks like FOCL Day contain L-theanine as well as several other nootropics (and of course, CBD) to create the ultimate superfood for your brain in just one capsule!
Taking It Slow With GABA
As you can see in my daughter’s favorite cartoon based on Aesop’s “Tortoise and the Hare,” the race goes to the slow and steady. That cadence fits for GABA as well. And while GABA is not one of the sexy neurotransmitters you see in the popular press, it should be.
Not as specialized as the more well-known messenger molecules like serotonin, oxytocin or dopamine, GABA is the brain’s primary inhibitory neurotransmitter.
It is the turtle of your neurons, the blinking red light of your synapses, your brain’s signal to calm down its firing. Formally known as γ-Aminobutyric acid, GABA ’s chief job in the central nervous system consists of reducing neuronal excitability.
The brain needs balance because too much excitement can be damaging. It’s one of the most important aspects of neuronal health. When the synapses fire too much and too often, they get hot like an engine with no oil. Called excitotoxicity, this occurs commonly in the major neurodegenerative diseases as well as strokes, epilepsy, traumatic brain injuries, alcohol use disorder, and the rapid withdrawal from benzodiazepines. Excitotoxicity often happens because of unhealthy levels of glutamate – the brain’s primary excitatory neurotransmitter (subject of the previous article in this series) and the yang to GABA ’s yin.
In a fitting twist of fate, GABA is synthesized from glutamate. Out of the great excitatory neurotransmitter comes the great inhibitory neurotransmitter. And working together, they both act as handmaidens that facilitate the functions of our endocannabinoid system ( ECS ).
GABA and the ECS
Do you know where the most CB1 cannabinoid receptors are located? The same CB1 receptors that THC uses to get you high? The majority of these famed CB1 receptors are embedded on your brain’s GABA -producing interneurons.
Interneurons – also known as relay neurons, connector neurons, or intermediate neurons – connect to small circuits in local regions of the brain (as well as connecting different brain regions). They act as the crucial middleman between sensory inputs coming into the body and the response of the motor signals that are transmitted back out.
As you can see in this diagram, the classic function of an interneuron is to insert itself into a circuit and, if activated, dial down the signaling. In technical language, GABA ergic interneurons “gate signal flow and determine network dynamics [and] are essential for sculpting network responses.” Via their inhibitory actions, interneurons prevent instability in the brain. And when you activate your CB1 receptor, the most likely response is the triggering of an interneuron’s release of GABA , something that carries out so much of the work done by the ECS .
While this ‘get-to-know-a-neurotransmitter’ profile focuses on GABA ’s higher-level neural processes, we shouldn’t overlook the importance of GABA ’s role in other areas such as:
- Brain development, where it regulates the stem cells, their migration and differentiation, as well as the formation of synapses
- Insulin production in the β-cells of the pancreas
- Suppression of inflammation in the immune response
- Acupuncture’s efficacy, which is partly mediated by the endocannabinoid system’s modulation of GABA
Anxiety, Benzos, and CBD
One theory about anxiety views it as a result of insufficient inhibitory control in the brain. In that context, using a benzodiazepine (like Valium or Xanax) to increase inhibition makes sense. Instead of directly activating a receptor like a key turning a lock, the mechanism of action for benzos is a “positive allosteric modulation” (signal boost) of the GABA a receptor.
Canadian researchers report that when patients received a medical cannabis prescription, half of them discontinued their benzos.
Benzos are positive modulators of GABA . So are barbiturates (the first generation of downers), the delightful Quaaludes (that a certain generation raves about), and that old human favorite, alcohol. The strengthening of GABA by these drugs leads to the dissociative and sedating effects that can be both pleasurable and terribly addictive.
Benzos aren’t big business just because of big ad budgets. As potent anxiolytic (anxiety-resolving) agents, they’re awfully effective – and possess quite the potential for danger. An overdose, either alone or combined with booze, can be fatal. And the withdrawal effects of benzos can also be lethal if stopped too quickly without tapering.
According to a 2019 Canadian study, when patients received a medical cannabis prescription, half of them discontinued their benzo prescriptions. A 2020 review article on neurological diseases reported that plant cannabinoids might help to restore a broken GABA transmission system. Plant cannabinoids, especially CBD , are notorious for their calming effect. In large part, this may be attributable to the endocannabinoid system’s control over GABA and the calming of the brain.
In rats stressed out by being restrained (they hate this), the endocannabinoid system helped to calm their racing heart via GABA – and if you blocked their CB1 cannabinoid receptor from working, their heart raced even more. In another animal study, Spanish scientists sought to explore how CBD exerts its anti-anxiety effects. They found that in mice with no CB1 receptors, CBD stopped working for anxiety. They also found that the presence of CBD decreased the levels of the CB1 receptor and the GABA a receptor in the amygdala (the fear center of the brain), while increasing CB2 receptor levels.
“It is tempting to speculate that CBD regulates, directly or indirectly, GABA a neurotransmission,” the researchers surmised. This observation concurred with previous findings of Australian investigators, who reported that CBD and the endocannabinoid 2- AG both interact with the GABA a receptor in a way that enhances the natural calming effects of GABA , the slow-down neurotransmitter.
Your Beautiful Nimble Brain
GABA ’s inhibitory effects can help your brain be more nimble while trending toward the sweet spot of moderate healthy activation. In this neuronal balancing act, your pay attention to this function is just as important as stop bothering to notice that. To stop from spinning out of control from too much stimulation, it’s essential for the brain to ignore signals that are no longer perceived as dangerous or relevant.
It’s been shown that a combination of dopamine and endocannabinoids regulate the GABA -releasing synapses in a rat’s prefrontal cortex (the highest area of the brain), creating what scientists refer to as “long-term depression” or LTD . That’s shorthand for your brain’s ability to reduce the activity of a circuit after it has been activated too many times. This reduction can last for hours or longer. It’s the negative side of synaptic plasticity, the ability to downgrade a signal so that you are able to upgrade it again if needed. Otherwise, your brain would reach a maximum level of all your circuits firing all of the time.
In addition to protecting the brain from excitotoxicity, the inhibitory effects of GABA influence both learning and memory. In a mouse model of memory, the ability of certain serotonin receptors to regulate spatial memory depends on a pathway involving CB1 and GABA . In another intriguing study, the signaling of GABA accelerates the breakdown of endocannabinoids, which triggers “learning-induced metaplasticity.” This means your brain’s ability to adapt and change comes, at least partially, via your endocannabinoids and GABA .
In the olfactory bulb (the locus of your sense of smell), endocannabinoids modulate your GABA ergic synapses. And in the taste center of your insular cortex, the CB1 receptor mediates GABA ’s plasticity of your taste learning system. It’s the endocannabinoids that regulate both GABA and glutamate in the striatum, a brain area associated with habit formation and movement control. The ability of the CB1 receptor to help mice be social and exploratory depends on the delicate balance between glutamate and GABA .
The GABA Health Files
For the specific disease conditions related to GABA dysfunction, let’s take a slow, deep science stroll through the GABA garden. As always, more clinical research is needed, but for anyone with these indications or areas of concern, it’s relatively easy to start harnessing the power of GABA and the ECS to improve your health.
- ALS : In a mouse model of amyotrophic lateral sclerosis, the CB1 receptor showed an ability to exert a very fine level of control over the signal transmission of both GABA and glutamate.
- Autism: According to this brain imaging study of humans, both CBD and CBDV help with autism via the GABA and glutamate pathways.
- Circadian rhythms: In the circadian rhythm section of your brain, cannabinoid signaling causes its effects by “recruiting” astrocytes (specialized immune cells of the brain) via adenosine and GABA transmission.
- Down’s syndrome: In a mouse model of Down’s syndrome, the CB1 levels are upregulated on the GABA neurons and downregulated on the glutamate neurons.
- Eyes: In the eyes of rats, CB1 activation helped to fine-tune visual signaling via modulation of GABA .
- Exercise and food: In mice, CB1 receptors enhance exercise activity and lower the desire for food via GABA neurons.
- Huntington’s disease: In humans, Huntington’s disease alters the cannabinoid and GABA receptors. In a mouse model, the level of CB1 receptors on GABA neurons plunges.
- Pain: In a rat model of pain, a synthetic cannabinoid induced analgesia via GABA a. In mice, CBD reduced pain via inhibition of GABA action potentials in the periaqueductal gray (a midbrain region that integrates the behavioral responses to internal stressors such as pain, as well as external stressors such as threats). In mice with nerve injuries, the CB1 levels go up in the cortex and the activation of these CB1 receptors causes pain relief via GABA interneurons. In mice, females experienced more pain relief from CB1 activation than males because females possessed more GABA -producing neurons with CB1 receptors in the relevant brain area. In rats with arthritic knees, the therapy combination of stem cell injections, endurance training (little treadmills) and ozone therapy (I assume they went to LA for this) decreased pain via the CB1 and GABA receptors.
- Puberty: In mice, insulin increases GABA transmission in a neuron that releases a hormone associated with puberty via the endocannabinoid system.
- Schizophrenia: In a rat model of schizophrenia, CBD restored cannabinoid and GABA signaling deficits.
- Sleep: The CB1 receptor helps to control sleep partially via GABA .
