10 Best GABA Supplements (2024) Reviewed and Compared

Never miss a glorious update - click here!

According to the American Institute of Stress, over half of Americans report feeling stressed every single day.

If this sounds like you, taking a GABA supplement might help.

Today we’re covering everything you need to know about this brain food and the best GABA supplements on the market.

What is GABA (Gamma-aminobutyric acid)?

GABA, short for Gamma-aminobutyric acid, is an amino acid produced by the body. Although it’s an amino acid, GABA operates as a neurotransmitter. It’s a chemical mailman for your brain. And like the USPS, GABA has certain instructions as a sender of information. It blocks certain brain signals, while activating others.

GABA can produce a calming, stress-relieving effect when the protein attaches to its appropriate GABA receptor.

Because of this, GABA has become a popular treatment for stress, anxiety, and insomnia. You’ll find it in sleep aids, in anti-stress supplements, and as a stand-alone supplement.

Why Should You Take a GABA (Gamma-aminobutyric acid) Supplement?

Today’s world is chronically stressed out. And according to the American Psychological Association, chronic stress can cause anxiety, muscle tension, fatigue, digestive issues, chest pain, insomnia, headaches, and more.

Research shows that consuming GABA can help reduce chronic stress symptoms.

For example, a study in Japan revealed that participants who consumed a beverage containing 50 mg of GABA before completing a problem-solving task reported less fatigue than the control group. In another study, results showed that consuming 100 mg of GABA reduced stress levels for participants completing a strenuous mental task.

Research also suggests that people with certain medical conditions, such as Parkinson’s disease, ADHD, and mood and seizure disorders, might have low levels of GABA. It may also help lower blood pressure. However, GABA is not an approved treatment for any disease.

Overall, GABA is a great supplement for lowering stress levels and relieving insomnia symptoms. Although GABA may help with certain medical conditions, additional research and evidence are still needed to support this.

The supplement industry is notoriously unreliable when it comes to quality. Every product on our list is third-party tested and GMP (good manufacturing practices) certified.

Now, let’s get into the best GABA supplements on the market.

1) Double Wood Supplements GABA

Price: $19.95

For a combination of quality and value, you can’t beat Double Wood Supplements’ GABA. First of all, Double Wood goes beyond the typical testing requirements, and displays the testing results of every batch. They manufacture their products in the USA.

Second, the value of the product is unmatched. Every bottle contains 300 capsules that each have 500mg of GABA. That’s double the dose of the GABA, oftentimes for half the price.

Third, there’s no fluff or fillers in this product, just simple, pure GABA.

For these reasons, Double Wood Supplements GABA is our top pick.

2) Quicksilver Scientific GABA + L-Theanine

Quicksilver Scientific Liposomal Gaba with L Theanine Highly Bioavailable Dietary Supplement 1.7 FL OZ (50mL)

Check Lowest Price

GABA pairs exceptionally well with l-theanine, an amino acid found naturally in green tea. L-theanine is famous for taking the “jitters” out of caffeine since it helps you relax and focus.

The combination, then, provides a powerful calming effect.

The second aspect that makes Quicksilver’s GABA + L-Theanine stand out is the delivery mechanism.

Simple GABA supplements often suffer from poor bioavailability (absorption.) This product uses liposomes to protect molecules so they actually make it into the bloodstream.

It comes in a simple spray. It’s dairy-free, gluten-free, non-GMO, soy-free, allergen-free, and vegan. It’s a high-quality, premium GABA supplement.

For all of these reasons, Quicksilver Scientific GABA + L-Theanine is high up at #2 on our list.

3) PureBulk Gamma-Aminobutyric Acid (Best Bulk)

If you prefer buying in bulk, consider PureBulk’s GABA supplement options.

They come in either powder or capsule form with different serving size options. Both the powder and capsule forms are free of sugar, soy, dairy, and gluten. PureBulk is a good option if you already know that GABA works for you.

Simply, it’s the best value on our list.

However, as mentioned, bioavailability is a question with straight GABA products.

How We Ranked

Here’s what went into our decision-making process for these rankings.

Overall Quality: The most important factor is that it comes from a reputable company and uses quality, third-party tested ingredients.

Every product on our list is third-party tested, but companies that go through stricter testing or use higher quality ingredients (like Thorne using a fermented form), then they’re higher up. 

Simplicity: You’ll find GABA in all kinds of different products. But if you want the benefits of GABA, we recommend taking a simple product. Generally, you’ll save money this way.

Cost/Value: Finally, all else equal, we looked for affordable products. GABA is not expensive to bottle up into a supplement, so we didn’t promote products that are gouging consumers on prices.


Are there any drawbacks?

Gamma-aminobutyric acid is considered to be a safe supplement, and there are no known drug interactions. However, commonly reported side effects of GABA are headaches, fatigue, digestive issues, and drowsiness.

Because it may cause drowsiness, you should avoid driving until you know how taking the supplement affects you. And as always, you should consult your healthcare provider before taking a GABA supplement.

Experiences vary from person to person. If you want a supplement that calms you down and helps you sleep, a GABA supplement is definitely worth a try.

However, it’s only safe at reasonable doses. Since it decreases activity in the central nervous system, if you take tons of GABA pills, you can put yourself in a coma. 

How does GABA work?

GABA is an inhibitory neurotransmitter. This means its job is to block stuff. It blocks certain brain signals, which decreases the activity of your brain. This, in turn, leads to a calming effect.

More specifically, its role is to block glutamate, the primary excitatory transmitter.

Because it slows down the central nervous system, it has other effects like lowering your heart rate and blood pressure.

Can I use GABA as a sleep supplement?

Yes. GABA is super popular in all-encompassing sleep supplements. You can create your own sleep stack by combining GABA with magnesium. It’s also popular with taurine, an amino acid, which, per some research, has a slight agonist effect.

But can GABA supplements really make it into the brain?

There’s some debate about whether GABA from supplements can it through the blood-brain barrier. GABA supplements do have an effect, though, which suggests at least some of it does. To increase this bioavailability, we recommend a product like Quicksilver GABA.

How do you increase GABA naturally?

We make GABA naturally. If we want to increase GABA, especially in the evening, that begins by optimizing our circadian rhythm. Movement during the day, avoid blue light in the evening, meditation, and breathwork are a few strategies.

This will also improve your sleep overall.

You can also look into GABA-rich foods, and consume these in the evening. 

Finally, gut health seems to be linked with GABA production. Make sure you eat plenty of vegetables and consider probiotic-rich foods like kimchi and greek yogurt.

Can GABA support mental health?

GABA supplementation has not shown substantial evidence to improve mental health, despite what some companies may claim. As a dietary supplement, GABA is not approved by the FDA to treat or prevent any disease. Likewise, despite some suggestions, it’s NOT a treatment for epilepsy.
