How Does CBD Boost GABA for Anxiety

We’re written extensively on how CBD works with Anxiety and one key component keeps popping up over and over.


Even though one of the most popular classes of anti-anxiety medications affects the serotonin pathways, GABA really is THE key lever for anxiety.

The other main class of medications, benzodiazepines, hits this lever way too well.

It has an immediate and powerful effect on anxiety but nasty side effects:

  • Very serious potential for addiction
  • Impaired thinking
  • Normalization (need more and more for the same effect)
  • Only useful for short term use
  • Anxiety and depression withdrawals

You can learn all about CBD versus Benzos here.

Benzo’s not only hammered GABA levels in one direction but they cause a powerful rush of dopamine (our reward neurotransmitter).

That’s the addiction side!

Research shows that GABA really is the key target for anxiety so that begs the question…

Can we improve its signaling without the terrible side effects of benzos?

What a great introduction to CBD.

CBD has shown a powerful anti-anxiety (called anxiolytic) effect.

You can read all about it at our comprehensive guide to CBD’s benefits for anxiety here.

Let’s focus on GABA and how CBD might directly impact its circuit in the brain.

We’ll cover these topics:

  • How GABA works (or doesn’t work) for anxiety
  • Issues that can affect GABA levels with anxiety
  • How CBD affects GABA levels for anxiety
  • What type of CBD to use to boost GABA for anxiety
  • How much CBD to boost GABA for anxiety

Let’s get started.

How GABA works (or doesn’t work) for anxiety

GABA is a powerful neurotransmitter in the brain.

In fact, GABA receptors are the most common type in our brains. It’s a key messenger in our brain.

It’s short for Gamma Butyric Acid (thank goodness!)

It’s the primary inhibitory chemical in our nervous system.

“Inhibitory” just means that it slows down activity between and within neurons in our brain.

It essentially blocks activity.

Let’s think of it as the “brake pedal” of our brain function.

In the brain or body, if there’s a brake pedal, there must be a gas pedal!

Hello Glutamate!

Glutamate is our brain’s primary excitatory neurotransmitter.

Interestingly enough, GABA is made from glutamate when its levels get too high.

These two chemicals are in a tug-of-war which, in a healthy brain, should find balance more times than not.

In tandem with the excitatory neurotransmitter glutamate, GABA modulates the inhibitory-excitatory balance necessary for proper brain function in mature brains

There are times we need more GABA (sleep for example) and times where we need more Glutamate (final exams).

The issue is when one is chronically excessive.

Too much Glutamate and not enough GABA is implicated in mania, ADD, autism, OCD, and….anxiety.

GABA is primarily synthesized via the GAD gene.

Vitamin B6, Magnesium, and Melatonin are positive “upregulators” of GABA production via the GAD gene.

GABA has many other important roles outside of just being inhibitory:

  • GABA drives production of brain immune responders called oligodendrocytes
  • GABA drives the production of myelin which protects nerves throughout the brain
  • GABA is neuroprotective under stress and inflammation
  • GABA interacts with progesterone for stress response and anti-anxiety effects (hint hint ladies!)
  • GABA increases levels of human growth hormone

In terms of anxiety (our focus here), the relationship is very clear:

The brain circuits in the amygdala are thought to comprise inhibitory networks of γ-aminobutyric acid-ergic (GABAergic) interneurons and this neurotransmitter thus plays a key role in the modulation of anxiety responses both in the normal and pathological state.

If you read our summary of CBD’s benefits for anxiety, you’ll see that the Amygdala (our seat of the fear and emotional response) is central to what’s going on.

Most importantly, we know that benzos are extremely powerful in reducing anxiety and their activity is directly dependent on the GABA receptor.

Benzodiazepines (BZs) produce most, if not all, of their pharmacological actions by specifically enhancing the effects of endogenous and exogenous GABA that are mediated by GABAA receptors.

So GABA is where it’s at in terms of the IMMEDIATE lever of anxiety.

A few interesting items on GABA levels:

  • Meditation has been shown to increase its levels
  • A single yoga session can boost GABA up to 27%
  • Specific types of gut bacteria can synthesize GABA

Let’s look at one more level up before diving into CBD’s effect on GABA.

The endocannabinoid system!

The endocannabinoid system and GABA for anxiety

We all have this system.

By “all”, we mean all living animals down to the sea urchin.

It’s been around about 600 million years now.

Researchers have really only started to explore how it works for the last 20 years.

GABA was discovered back in the ’50s so this tells you how new the endocannabinoid system is.

Research is showing that it’s tasked with balancing other key systems in the body:

  • Nervous system including neurotransmitters like GABA and Glutamate
  • Endocrine system including hormones like progesterone, estrogen, and cortisol
  • Immune system including inflammatory response and histamine

The intersection of these three systems accounts for much of what ails us.

Let’s zoom in on the neurotransmitters since we’re talking about GABA specifically.

Is the endocannabinoid system even involved with GABA production?

The answer is yes.

2-AG (the most prominent endocannabinoid in the brain) is directly involved:

The endocannabinoid 2-arachidonoyl glycerol (2-AG) potentiates GABAA receptors at low concentrations of GABA

This speaks to the endocannabinoid system for “balance”.

Notice how this happens at “low concentrations”.

It’s a back-up support system to GABA.

Too little GABA triggers 2-AG to boost its levels.

Think of 2-AG as back-up power for GABA production when it gets too low.

Later in that same article, it was shown that 2-AG boosted the effects of diazepam (common benzo). Maybe you know it as Valium.

The benzos are known to primarily act by boosting GABA levels.

That’s 2-AG.

What about Anandamide, the 2nd most prominent endocannabinoid in the brain?

We have new insight on this which is extraordinary.

There’s a new study which shows that a woman who does not feel pain and anxiety has a specific mutation which causes her situation.

The mutation in question was for FAAH.

Guess what FAAH does….

It breaks down Anandamide.

In Jo Cameron’s situation, her FAAH isn’t clearing out Anandamide and she doesn’t feel pain or anxiety.

FAAH is an endocannabinoid. Anandamide is an endocannabinoid.

Skew the levels of each and you have no anxiety. Or pain!

There’s a full review of the (fascinating) connection between CBD and the woman who can’t feel pain or anxiety:

Those are just the levels of endocannabinoids and GABA.

Other factors can affect GABA levels which are influenced by endocannabinoids.

For one, stress has been shown to eat up GABA in the brain:

Stress and fl-Carbolines Decrease the Density of Low-Affinity GABA Binding Sites

Psychological stress has also displayed a powerful effect to reduce levels of GABA in important areas of the brain for anxiety:

Prefrontal GABA decreased by approximately 18% in the threat-of-shock condition relative to the safe condition.

This may partially be due to the inflammatory response in the body on the levels of GABA.

GABA has been shown to calm immune response, and equally, inflammation can reduce GABA levels.

Cytokines and glial cells are the main weapons in our inflammatory response:

Inflammatory cytokines are known to modulate GABAA receptor-mediated responses and glial overexpression of certain cytokines lead to spontaneous seizures and decrease in GABAergic cells

Let’s finally jump into CBD’s effect on GABA.

How CBD affects GABA levels for anxiety

Let’s speak specifically about CBD and GABA levels here since we’ve established the direct effect it has on anxiety.

We’ll start with the endocannabinoids above which affect GABA levels.

2-AG is a strong determinant.

Both CBD and 2-AG were shown to increase the levels of GABA production:

The maximal level of enhancement seen with either CBD or 2-AG were on α2-containing GABAA receptor subtypes, with approximately a 4-fold enhancement of the GABA

Interestingly, it didn’t have this effect through the benzodiazepine receptors on the GABA neuron.

Based on the information above for anxiety:

  • We want to boost anandamide
  • We want to boost 2-AG
  • We want block FAAH

These are all anti-anxiety moves involving the GABA pathway.

So. what does research show for CBD and drivers of GABA for anxiety?

It was found that CBD inhibits both AEA hydrolysis by FAAH-containing membrane preparations (Watanabe et al., 1996), and AEA uptake by RBL

This basically means that CBD blocks the FAAH breaking down of anandamide!

That’s two of the three above!

In fact, CBD was the only cannabinoid to block FAAH:

CBD was the only compound to inhibit FAAH

The net effect of this on GABA…

Across regions, CBD increased GABA+ in controls, but decreased GABA+ in ASD; the group difference in change in GABA + in the DMPFC was significant

This was a study focusing on Autism (the ASD group).

Interestingly, CBD increased GABA across different areas but actually decreased it in people with autism, especially in the prefrontal cortex.

This may speak to a different balancing required for people with autism (not enough activity in the prefrontal cortex, therefore less boost to GABA which is inhibitory).

For the control group, a net increase in GABA signaling across brain regions.

Another study on mice showed a similar anti-anxiety effect from CBD and diazepam (benzo):

mice treated with cannabidiol and nabilone spent a greater amount of time in the open arm of the maze, an effect similar to that produced by diazepam, the reference anxiolytic agent.

Finally, the anxiolytic effects of systemic CBD partially depended on GABAA receptor activation in the EPM model

We discussed how stress eats up GABA in the brain.

Chronic stress and inflammation are being tied directly to anxiety.

The effects of stress on GABA levels are well documented. A few quick takeaways:

Chronic stress impairs GABAergic control of the amygdala through suppressing the tonic GABAA receptor currents.

This just means that chronic stress interferes with GABA signaling in the key area for anxiety. the Amygdala.

Interestingly, when they then introduced an anti-inflammatory, the GABA production returned after the stress:

Wang GY demonstrated that chronic or acute administration of dexamethasone (DEX) upregulates GABA release and GABAergic neuronal spiking in the amygdala

So why does this matter for CBD?

CBD is a powerful anti-inflammatory and most importantly, is a powerful ally against neuroinflammation:

Cannabidiol (CBD) has emerged as a promising strategy to treat the inflammation that results from microglial hyperactivation [78], with no psychotropic side effects. Moreover, CBD has been shown to attenuate oxidative and nitrosative stress in several human disease models

The microglia note above speaks to CBD’s ability to calm the inflammatory and immune response in the brain as well.

This is just a smattering of dozens of studies regarding GABA/Glutamate balancing and CBD.

You get more information here:

There’s an important concern when picking the right CBD for anxiety and GABA levels

Let’s look at that now.

What type of CBD to use for boosting GABA with anxiety

This is very important.

Remember that GABA is inhibitory (the brake) and Glutamate is excitatory (the gas pedal) in the brain.

Too little brake in the emotional circuit can cause anxiety.

It also helps if we take our foot off the gas pedal (glutamate, stress, and….histamine!)

Histamine is a powerful excitatory neurotransmitter in the brain.

Most of us know histamine from its induced allergic response.

In the body and brain, it is very excitatory and part of our immune/inflammatory response:

These results suggest that in rats acute stress increases colonic mast cell histamine content. This effect is mediated by the release in cascade in the brain first of IL-1 and secondly of CRF.

IL-1 is a cytokine (inflammatory agent) directly tied to anxiety above.

CRF is even more interesting. You can learn all about it at our CBD for Social Anxiety for CBD for corticotropin-releasing factor for anxiety

It is a circuit between the brain and body for stress response and. anxiety!

That’s why allergies and histamine release can feel like anxiety!

That’s also why antihistamines can reduce anxiety (see a comparison of anti-anxiety meds and CBD) and a known side effect is drowsiness (similar to benzos).

Most importantly for this article is that an increase of histamine will eat up GABA.

The two represent another push-pull relationship that governs our wake/sleep cycles and other key balancing acts.

Here’s the deal. everyone is pushing “full-spectrum” or “broad spectrum” CBD oil out there.

The biggest brands.

Full-spectrum just means CBD is added back to hemp oil or has other cannabinoids.

All that plant material is likely to trigger histamine responses for 40-60% of the population.

On top of this, they may have THC up to .3% which can actually cause anxiety.

Check out why in our CBD versus THC for anxiety article for lots of research.

On both accounts, that’s going the wrong way.

Especially since the dozens of NIH studies, we have listed are based on CBD by itself!

We literally crafted IndigoNaturals CBD based on this research and for anxiety (see our story here).

Now. how much CBD for anxiety and GABA level support.

How much CBD to boost GABA for anxiety

Here’s where it gets interesting.

Studies actually show that the anti-anxiety effects of CBD are on a bell curve.

This just means that they increase as we go up in dosage until a certain point where they start to level out.

The research is showing that at a higher level, CBD may trigger other systems (PPAR, etc).

A study looked at anxiety relief for humans and found that 300 mg of CBD presented a significant antianxiety effect.

This is especially true for the effect of CBD on long term anxiety.

The secret star there is called BDNF. our brain’s fertilizer!

The effect was much less at 150 mg or 600 mg.

Now, it makes sense to start low and test your effects.

We see lots of clients who get relief at 40-50mg up to 100 mg.

It really depends on your particular situation.

Anxiety is a great test since we can tell right away when we’re getting relief.

Hey Evan. Check out How I Weaned off of Benzos with CBD here:

Yes, the brain will have an opposing effect when we juice up a neurotransmitter like GABA. The addiction side comes more from this effect on dopamine. It should normalize with time and the endocannabinoid system is key to homeostasis or balance. That’s why the research shows CBD “modulates” or “normalizes” GABA levels…not solely increase. Otherwise, you would see the overdose or knock-out effect from higher CBD doses as GABA goes too high. Also, look at what might be eating up GABA to begin with (stess, inflammation, etc).

Hello- I recently came off benzos. I was prescribed them on and off for about 7 years. I believe my Gaba system is very damaged and I’m working on repairing it. I have found CBD to be of great help. However I am hesitant to take anything Gaba-ergic as I don’t want to further damage or down-regulate my Gaba system. Would CBD be safe to take while in this recovery?

Hey Florence! CBD Isolate by itself should not cause a histamine response. In fact, research shows that it does the opposite. Check out CBD and histamines here. Was the CBD full spectrum? We had terrible responses from really big brands due to histamine responses to the plant material in full spectrum. That’s why we made ours from two ingredients: CBD Isolate and MCT oil as a base. Histamine works in opposition to GABA and CBD actually helps to boost GABA. Let me know what CBD you had before but we’ve seen people respond that their sinuses cleared right up with our oil.

How about combining a GABA supplement with CBD?
I heard this disolves the effect of both? I now use GABA alone. Had a terrible histamine reaction when I added CBD! Is this the effect from the combination? Thank you for answering…

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 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!
