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.

    Great Sleep

    If you struggle with a good night's sleep, give this a go.

    So this is what sleep feels like

    I had no expectations when I bought this, because nothing else has worked for me. I've had chronic insomnia for so many years that I'd forgotten what it feels like to sleep through the night until I tried GABA, and I've tried a LOT of sleep supplements. I don't get the tingling other people mention, I just get nice and relaxed about half an hour after taking it. I mix it in a glass of water and can barely taste it. I have tried to cycle it as recommended but the insomnia comes right back, which is a bummer.

    Very good product!

    Helps me sleep, I actually had nights of sleeping 5 or 6 hours straight, which didn't really happen in the last 15 years!!!

    Best sleep ever

    Since taking GABA I fall asleep quickly and deeply and my stress levels have dropped significantly. Love the tingle when it kicks in. Have been recommending to all my friends. Mixes well and has no flavour so it’s just like a drink of water before bed

    Gives me a good nights sleep and leaves me feeling genuinely rested come morning.

    Great GABA

    This is a great product for sleep and growth hormone. Use carefully according to directions; it is very effective stuff.

    helped with sleep initially

    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

    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

    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?
