Gamma-Aminobutyric Acid

Gamma-Aminobutyric Acid (Gaba) is the most abundant inhibitory neurotransmitter in the brain.

Gaba can help induce relaxation/sleep and can stimulates the anterior pituitary, leading to higher levels of growth hormone.

Increased levels of growth hormone can have positive effects on anti aging, on lowering body fat levels and increasing lean muscle levels.

Some states in Australia and New Zealand have restrictions on purchases of Gaba of 1kg or greater. We suggest you check your relevant legislation before purchasing.


Consume 2g of Gaba per day, ideally before bed. Doses up to 5g are said to increase effectiveness. Do not consume more than 5g per day. A flat 5ml scoop provided equals 2.45g of GABA. Ideally GABA should be cycled every two weeks.


Combine powder with liquid and consume immediately.


100% Pharmaceutical Grade Gamma-Aminobutyric Acid.

    helped with sleep initially

    Posted by Jared on May 02, 2018

    I liked this as a bit of a sleep aide but it didn't always work. I didn't notice any other benefits. I also got hot tingly feeling in my face and head and shortness of breath at times when going a full dose

    Growth hormone production

    Posted by Brian on Mar 21, 2018

    Gaba gives me serious paresthesia (tingles) which I like, because it means its working, but the best result I've had from it is the boost in growth hormone production. I've actually had symptomatic RSI in my hands, which is a sign of growth hormone working from injections of the stuff. My skin has improved and I'm looking fuller than ever. Cuts heal quicker on me than before. I'm 51, so may be getting better results than someone younger because of the lack of GH. All in all, one of the best supplements I've tried.

    Real results

    Posted by Ivan on Mar 20, 2018

    Taking supplements rarely show measurable results. Gaba was difficult to take initially for me because it caused a hot tingly feeling in my face and head for a few minutes soon after taking. The effects on sleep and recovery though, were outstanding. I now get out of bed thoroughly rested. I can now workout for longer and more often. How good is that?

    Fantastic product for sleep and restless legs

    Posted by Leanne on Feb 16, 2018

    I was told about this product from my Pain Specialist for restless legs. I was taking melatonin tablets at the time and the side effects were serious migraines. Now I take 1 heaped spoon of GABA each night 1/2 hr before going to bed, I have the best 8hrs sleep and my legs are pain free. Can't thank you enough for the great door to door service. Wonderful product

    To be honest, I’m unsure if I’ve noticed any benefit from the use of this product, but I still remain hopeful
