Product FAQs
How does GABA taste?
GABA is unflavoured and is generally considered to be slightly bitter.
What is GABA made from?
GABA is synthetic.
How is GABA packaged?
GABA is packaged in resealable 250g pouches.
Is the packaging for this product recyclable?
In theory yes, but not in all council areas right now.
The REDcycle program has been discontinued, and the industry is working together to find a solution to continue recycling soft plastics. For now, we recommend checking with your local council, but most require you to put the packaging in your regular landfill bin.

Can I receive a discount by buying more than one bag of GABA at once?
Absolutely! Price breaks for GABA begin when you purchase more than two 250g bags. Just add more than that to your cart to see the savings.

What Our Customers Are Saying
Reviewers commonly described the powder as easy to dissolve, nearly tasteless and good value. Many reported that it supported relaxation before bed, helped them fall asleep more easily, remain asleep longer and wake feeling more rested. A small number reported no noticeable benefit or effects such as morning drowsiness, headache, tingling or shortness of breath, particularly at higher amounts. Several reviewers also praised the prompt delivery.
Amazing purity.

Excellent product
Courtney M on 01/06/2026Verified buyer
I was recommended to try GABA a few years ago and I finally got around to it. I am so glad I did. I wakeup and actually feel refreshed in the mornings, which is something I've longer for, for quite a while. I have shared this product with my parents and I am happy knowing that it's helping us all with rest, mood and energy.

Bit to soon to say
Jenny T on 12/04/2026Verified buyer
Only been taking it for few days so bit early to review. Easy to take though.
Great natural sleep onset
John C on 28/02/2026Verified buyer
My doctor put me onto GABA and I was buying 150g for $70.95 so when I saw Bulk's price I had to try it and have been buying it regularly for the past 4 years. The nature of the powder has changed, it is now crystalline doesn't dissolve as well as it used to, and now has a strong smell, but still works.
Get a good sleep
