As long as it is consumed in the recommended doses, GABA is considered safe. Taking more than the recommended amount may result in issues such as depression, anxiety or insomnia. It can also cause tingling in patches all over the body, numbness of the mouth and a sense of nausea. In rare cases, GABA has been responsible for causing such a massive imbalance in brain chemistry that it actually caused seizures. This is very rare. Because GABA is an amino acid, it is important to remember that supplementing this will have an effect on the levels of other amino acids in the body.

Anyone that has ever suffered serious problems with their kidneys or liver should avoid this product until they have discussed it with a doctor.


GABA is water-soluble and can also be mixed with juice effectively as well. It has little taste to it. This product should be stored in an area that is free from light, heat and moisture in order to preserve its potency.

Helps sleep through hot flashes
I take 1/4 teaspoon before bed time in water.It helps me to sleep through the hot flashes,that wake you up to have them in the night.It worked for me!*

On 10/9/2018 Kathy said...

Remarkable Product
I have been using GABA with a couple tablets of ZMA at night and
have had some of the soundest sleep I've had in a while. I suffer from periodic bouts of insomnia and usually depend on otc sleeping pills.
I decided to give GABA a try after reading some info on its sleep enhancing properties and am very pleased with the results. As usual, Bulk Supplements provided a wonderful product.*

On 10/7/2018 Raney said...

Great Supplement
The taste is tolerable and it helps with a good night's sleep. The effects become observable relatively quickly. Very good product!*

I use it for sleep and love it. *

On 9/25/2018 ERIK said...

Helps with sleep
I picked this up to help with with my insomnia. I've been taking it for a week now and I can definitely tell the effects. I got the 1kg bag to keep me stocked up for a good long while. *

On 9/16/2018 Chris said...

Subtle but calming
I have been taking the full dosage (1/8 teaspoon) for a little over a week now. I take a single dose before bedtime. For me the results are more subtle but I do get a refreshing nights sleep (relaxing REM) and a sense of calmness throughout the day.

I take it with magnesium citrate to enhance the calming effect. Overall, I am satisfied with the results and the ability to purchase the product in bulk is amazingly cost effective. *

On 9/7/2018 Matt said...

Powdered GABA
I love the convenience of powdered supplements, I just mix them in with yogurt or in a glass of water. Bulk Supplements GABA dissolves easily and the powder lets me adjust the dose depending on the purpose. I find it helpful for slowing down racing thoughts, especially at bed time (it's considered an inhibitory neurotransmitter - one that slows rapid neuron firing) and for helping calm a non-productive cough.*

On 9/1/2018 Gail said...

Great product!
I'm taking this product 30 min before I go to sleep, and wake up full of energy in the morning. I have been buying Bulk Supplements products for years now, and they are very high quality products. Gaba its a perfect sleep remedy. *

On 8/20/2018 Helidon said...

Gaba Works
After taking this for a little over two weeks I have noticed that I am much more calm. Just a relaxed peaceful feeling.Also I notice that I dream much more and the dreams are more vivid. I love it and will never go without it!*

On 5/17/2018 Tanya said...

Works in the peripheral nervous system.
GABA won't work in the CNS because it can't cross the BBB, but it does wonders in the PNS. I mainly use GABA to prevent cramping.*

On 2/6/2018 Joe Schulz said...

I like it!!
This dissolves super easily in water and has a slightly tart taste which I weirdly enjoy. I think it helps with calming and you can't beat the price for what seems to be a mutil-year supply based on the dosage! Woohoo!*

On 12/4/2017 Lisa said...

Gives you Dreams
Rarely had dreams before I started taking this, have been taking consistently double the recommended dose for about 2 weeks and i constantly dream. I fall asleep much quicker however i wake up more tired than usual. Would recommend for people who have trouble falling asleep although you might find it a bit harder to get out of bed in the morning.*

On 11/5/2017 Aaron said...

It really works!
The powder easily dissolves in water. I took this before bed and within 30 minutes I was getting sleepy. Not only did I fall asleep quickly, but woke up refreshed! If you are not getting the quality sleep you know you should be try this product!*

On 8/31/2017 Patricia said...

I highly recommend this product to those who have anxiety or panic attacks great product, five stars.*

On 3/28/2017 John said...

Good Stuff
Works well. When they say powder, they mean it. It mixes well. Seems tasteless. Very pure product. Very affordable. *

On 1/1/2017 Martin said...

I am very pleased with the supplement. It works better than expected. I have a long history of sleep difficulties and the supplement definitely helps me sleep throughout the night. However, at half the recommended dose, I feel extremely tired upon waking. With this in mind, I would recommend sampling the produce on the weekend/off days to ensure that you have time to adjust. [Although, needless to say, each body is different, and I do not remember others reporting such.] I intend to experiment with timing and dosing to find the perfect amount for me. I should note that this is a high quality product at a great price! I wouldn't buy anywhere else. *

On 12/3/2016 Elizabeth said...

Promotes sleep
I decided to try out this product after hearing mixed reviews. I can definitely agree that this product helps in relaxing my muscles and giving a well night's rest. I've been lacking sleep due to late nights studying and late night gym sessions with (caffeine) in my system. This product is definitely another staple supplement that I will be continuously purchasing for my stack!*

GABA Powder
What a relief to get a good night's sleep after years of waking every 2 to 3 hours and taking an hour to get back to sleep. First night I took 750 mgs
I woke at 1am and went right back to sleep until 7am! Put the powder under my tongue and fell asleep soooooo fast!*

On 11/28/2016 Marguerite said...

Gaba powder
It provides calming effect when GABA levels are low. It mixes well with water. However, this powder doesn't have a pleasant taste*

On 11/4/2016 Iwona said...

My wife takes GABA along with other Bulk Supplement products. They seem to help her feel better. Good products and fast shipping.*

On 10/25/2016 Steven said...

Great for sleep!
I've always had trouble sleeping and this stuff helps so much! Not only do I get to sleep but my dreams are much more vivid and I wake up feeling refreshed. It has helped my insomnia and anxiety a lot! Bulksupplements has amazing quality and I won't trust another producer. *

Afterwork Chill Pill Mix
Everyday after work or after periods of physical and mental stress this is the ultimate cure. Over the years I've tried many brands but nothing beats BULKSUPPLEMENTS. Only buy kilo's of the best white powder.*

GABA Sleep Aid
I have chronic insomnia where I would wake up after about 5 hours and was looking for an alternative that was different from the doxylamine succinate, benedryl, melatonin, l-tryptophan/5-HTP, and other herbal substances I have already tried. Drinking milk, niacin, and magnesium did not do the job for me.

I saw good research abstracts and ancedotal reports about GABA so I ordered some recently to give it a try. It is more natural than other sleep aids, and less chance of adverse side effects.

Initially I used 50% of the recommended dose of GABA but did not notice any change from the current sleep patterns. So I went with the recommended dose of 750mg.

My total and REM sleep periods increased after taking the recommended dose of GABA powder just before bedtime. It works.

Based on my resuts, I am adding GABA to my sleep aid supplement cycle to use a few times a week.

The order from Bulk Supplements came quickly and at a reasonable price compared to other sources.*

On 5/31/2016 Thomas D said...

Sleep Improvement Noted
I recently ordered some GABA. According to scientific research and ancedotal reviews, one of its major benefits is to help promote a full and restful night's sleep, which is something I have not been able to achieve on a consistent basis for several years.

GABA does not have harmful side effects and is more natural than prescription medication. The recent news about cholinergic sleep aids such as doxylamine succinate and benedryl contributing to cognitive deterioration sent me searching for a safer sleep aid.

I began taking GABA at a dose 50% less than recommended, along with other non-cholinergic sleep aids. It did not seem to make any appreciable difference in sleep quality.

So I upped the dose to the recommended amount of 750mg and did not include any other sleep aids to see what would happen. At the recommended dose I slept through the entire night, had dreams, and woke up rested.

Based on my experience I will continue to use GABA as a sleep aid a few days per week, cycling it with other things.

The quality and effects of this product are as advertised, and shipping was fast. Bulk Supplements works hard to keep customers coming back. I am pleased with the GABA and would recommend it for anyone wanting to improve the quality of their sleep or reduce insomnia.*

On 5/30/2016 Thomas D said...

This has helped us fall asleep and wake up feeling better in the morning.*

On 4/8/2016 AJ said...

Asleep in 15 minutes
This ranks in the top two sleep aids I've ever tried. There's no drowsiness when you wake up. You feel refreshed after a good night's sleep. When I have trouble sleeping, I take this supplement and I'm out in 15 minutes. The tell tale sign the supplement is working is I get a slight tingling in my face. A minute later, I'm out. Works every time.*

On 4/8/2016 Sean said...

Take 2-4 capsules for moderate sleep help. For GH boosting take 2-4 grams. Great Product!*

On 3/27/2016 Nicholas said...

Relaxes Me Before Bed
I purchased the Gaba in addition to 5-HTP and Tryptophan to help me sleep better. I recently stopped taking a prescription sleep aid and was having trouble winding down. This product helps my body and my mind to relax making it easier for me to fall asleep. I take the recommended dose in the morning and at night. I put the powder straight under my tongue, the taste is ok. Great service and speedy shipping - thanks!*

On 3/7/2016 Janet said...

Can't really feel a benefit
I ordered this to try along with L-theanine for sleep at night. The theanine works great but I just don't see any evidence of any extra benefit from this GABA. I'll stick with it and see if my opinion changes. Three stars because it is a pure product and as always, it shipped promptly.*

On 2/11/2016 Bill said...

Works well
Took this after a workout and felt very relaxed. Shipping was fast as usual from Bulk Supplements. A++ company with A++ products. *

On 1/17/2016 Daniel said...

Premium GABA
The order was shipped immediately and the quality of the product was the best I've seen. My company plans on buying much more for addition into several formulas. Thank You*

On 12/23/2015 Brian said...

Overall, Bulk Supplements Gabba has done very well in helping me sleep. This is one of the best sleep supplements that i have every tried. I usually take a dose of 1.5 - 3 grams, which is not the recommended dose, but has seemed to benefit me personally with falling asleep and obtaining a deep, restful sleep throughout the night.*

On 11/10/2015 Christian said...

Helps me relax
A friend recommended I try GABA for anxiety. While I did experience some tiredness when taken in the morning, it DOES help me stay calm at night. Quick shipping!*

On 10/13/2015 Ryan said...

GABA Powder
This truly is a pleasure to get a clean product without the laundry list of fillers and who-know-what in most capsules. I mixed it with water. Under the tongue was a bit strong for me. I was amazed that the water mixture was totally dissolved and very close to flavorless. Wonderful! The efficacy and dosage was as described. The shipping was amazingly prompt. My only wish would be for a aluminum container that was easier to reseal. Mine is very difficult to get completely sealed after opening. Other than that....good job!!*

On 10/5/2015 jim Knutson said...

I would recommend this product to anyone who suffers from constant pain, such as a migraine or maybe a mental illness, five stars, highly recommended.*

GABA and CFS & Fibromyalgia
This my first time trying bulk supplements. My wife has significant challenges with energy and pain. She is responding to GABA as hoped. I anticipate with a month or more on the product she will experience significant lessening of symptoms.*

On 8/13/2015 Eric said...

definitely real
I stand by bulk supplements, hard rhino was garbage but not these guys. All my products have been up to par and shipped damn quick. This GABA is real i take a large 5 gram dose before bed and i get the tingles and shortness of breath for a couple minutes that you are supposed to get so it definitely the real deal*

On 7/28/2015 brian said...

Research the benefits many uses of this neurotransmitter
It's no exaggeration that this stuff will help you sleep, stay relaxed, and keep calm. Absolutely do not exceed the recommended dose daily! This product is no joke and has many brain benefits. I take the first half as a part of a pre-workout stack for GH, and the 2nd half at night as a part of a sleep aid stack. I trust this manufacturer to produce clean product with no contaminants, deliver fast, and save money buying bulk. *

It does work for mental fog
i started taking this recently because I'd read that just a little bit is helpful for mental fog. I am glad I trusted the reviews, I could sense a difference. It was like a pick me up. I don't think it was the power of suggestion and even if it was the power of suggestion (believing others reviews) I am glad I went ahead and purchased it. I also read that this product is found in skin care item. Gotta try that next*

Gaba Review
I received the GABA within three days of ordering and the quality is exceptional, as usual. I use the GABA as a sleep aid and it works well. Bulk Supplements is a great company with exceptional products. Two thumbs up!*

On 5/5/2015 John said...

Works great!
I am a huge fan of their other products and fast shipments. I do feel a lot calmer when I do take GABA. I have only taken it for a few days, but plan on taking it for a while to see longer term effects. *

On 5/3/2015 Christina said...

New to Gaba
Has an noticeable flavor and dissolves well. I am trying this for the first time, and so will update my review.*

On 5/1/2015 Rosemary said...

Only dosing for a week, but it appears that my wife and I are sleeping better. It seems to just quiet the mind so that sleep can come more easily. Time will tell, but for now I am taking it at least every night and some mornings. Good stuff and VERY LITTLE taste if you want to just shoot it into some water. *

On 4/26/2015 Brian said...

All products that I have received from bulksupplements have been pure and as expected. I give them a thumbs up compared to the various sketchy companies out there.*

On 4/24/2015 Glen said...

Gaba (Great seller and quality!)
Love this compound! Use about 500mg every day with 100mg l-theanine. Very calming effect and stabilized mood. Shipped very quickly and powder is superb quality! *

great for occasional anxiety, insomnia
GABA is my go-to supplement to help with occasional anxiety and insomnia. better results than anything else i've tried, and no adverse side effects, plus with this product no fillers or excipients.*

On 4/8/2015 Kevin said...

Great product
I have supplemented with a Gaba combination formula, off and on for the past 6 months. I thought it was time I mix my own formula. This product mixes very well, has virtually no taste, looks beautifully clean and it works. It helps me remain calm during a stressful schedule and my sleep comes more easily.
The packaging is excellent and sturdy, so the powder stays fresh. I received my order quite promptly.
Thank you Bulk supplements :)

Aids sleep for some and for others, may cause insomnia!
Bulk Supplements products are always of the highest quality and this one is no different. Like many people, it puts my husband right to sleep. This seems to be the norm, yet for a few people, it may actually act as a stimulant. (Oddly enough, I noticed it is sometimes contained in pre workout supplements). Unfortunately I am one of those whose brain is activated by GABA. I took it last night and was wide awake until 5 a.m.! I researched GABA and it appears it activates seratonin in the brain. I've noticed anything that increases seratonin such as SSRI antidepressants tends to give me insomnia. More people than not say GABA calms them so, try it, but try it with caution and see how your body reacts if you have chronic insomnia. As for me, I will only use it early a.m. as part of my pre workout stack from now on! *

On 3/16/2015 CH said...

I started using this product to get off of Rx antidepressants. I have seen marked improvement in mood, focus and quality of sleep. I'm very grateful.*

On 3/5/2015 Wendy said...

loveee it
I have had this in my arsenal and really like it because I sleep well, and seem to be in my REM sleep. I wake up refreshed because i slept soundly, without and extra hours sleeping. I will order again for sure. oh, i have been using this with 5-htp too. I was taking 5-htp for a month before adding this supp and i can tell a good difference adding this one. *

On 12/25/2014 Mike said...

A dose of GABA before sleep with a little melatonin does wonders. Never wake up feeling tired even after a long day/night at the gym. Gives me the rest I need to keep at it even with a lot of stress. Also the shipping was fast and the price was excellent.*

Helps with sleep
I havent taken it long enough to see an increase in HGH yet, but it has helped with anxiety and helps me sleep better at night. So far I really like this product.*

On 9/30/2014 Meg said...

slept like a baby
My order came quickly as expected from previous dealings with this company. I've read some research that this molecule is supposedly unable to cross the blood/brain barrier. Well something is getting thru because I experienced a subtly sunny, pleasant and productive day after dosing with the recommended 1/4 teaspoon. And a very pleasant sleep hours later. No big buzz or anything like that, but a pleasant aura of competence.*

On 9/24/2014 Jim said...

Great stuff!
We've recently discovered gaba and love it!! It definitely helps us to relax while falling asleep, and get a much better sleep. Amazing stuff, and we love purchasing from!*

On 8/27/2014 James said...

High quality! New supplement resource!
Having used expensive supplements over a broad range of applications for over 40 years I reserve my enthusiasm until I've had the opportunity to review multiple sources of information and conduct my own personal test trials. I was pleasantly surprised to find that the quality of the pure crystalline GABA which I've recently received from Bulk Supplements seems to be excellent. I use it in careful, incremental doses to address hyperexcitability of neuromuscular junctions. The inhibitory neurotransmitter activity of GABA is a helpful adjunct for the purpose of relaxing formerly painful neural and rigid myofascial tissues. I also appreciated the responsible inclusion of comprehensive cautionary information regarding each of the supplements being sold on the Bulk Supplements website. So very im-ortant to be aware and careful re: kidney and liver health.


On 8/5/2014 Clare said...

Great Product
I received the shipment of GABA after only a few days from my purchase date. I took the recommended dose and had great results. I felt anxiety from excessive caffeine intake and the GABA definitely helped bring on a subtle calmness. *

On 7/5/2014 James said...

I love it!
People have talked about this leaving you with a hang over in the morning, but i don't feel it. If there is one it is nothing like the hangover I get with the prescription medicine I took. GABA helps me get a good nights sleep. I also take 5htp and glycine at the same time.*
