What customers say
Customers generally find this GABA supplement effective for improving sleep quality and reducing anxiety. Many appreciate its convenience, as it dissolves quickly and is easy to take on the go. The taste is often praised, though some users report no noticeable effects. A few mention that the tablets can become discolored if not used frequently. The product is noted for its small size and high-quality ingredients, with several users highlighting its calming effects during stressful situations. However, effectiveness varies among individuals, with some finding it highly beneficial while others see little to no impact.

These tiny tablets are a lifesaver when I feel a wave of stress or anxiety coming on. I just let one dissolve under my tongue, and I feel a sense of calm within minutes without any drowsiness. They're so convenient to carry with me for on-the-go relief, discreet enough to use even at my desk. This is the fastest-acting and most effective GABA I've tried for managing daily tension.

I have to call this out
Verified purchase
Due to recently stopping supply of melatonin to Australia because the Australian government want to regulate the supply by only Australian companies where 30 tablets of 1mg melatonin cost $36.00au, this was recommended as a substitute, well it is not, it doesn't do anything at all. Not even close to the calming effect of melatonin no effect at all. Sadly I now have to source it elsewhere from companies who will still supply to Australia. It is perfectly legal to import if you are doing it for personal use, this ban is ridiculous.

I love GABA, I usually take it in 500 mg. I wanted to try this as something to take during the night if I wake up and struggle to get back to sleep. I noticed two things, the dose doesn't seem to be high enough for me, and the ingredients make me thirsty, I think because it's sublingual. If you found this was useful, kindly consider giving this review a like :)

Easy to take
Verified purchase
The main reason i chose this product is because of how easy it is to consume. It's small and melts in the mouth so there is no swallowing involved, i know some people don't tolerate much of that. Gaba itself is very good of course, for me it works the best before bed, helps with falling asleep quickly

These sublingual tablets are fast absorbing and I feel like they are effective in creating a calming effect. I've tried taking 2 at night to help with insomnia and it's had some effect in helping with relaxation.

GABA is one of the things we overlook in helping for mood and other things, this sublingual tablet is great to try and see if you have any deficiency you'll know The quality is good, the ingredient as listed, you also have that sugary taste which isn't good if you're picky like me

I started taking these tiny tablets to help quiet my racing thoughts at night, and the difference has been genuinely surprising. They dissolve under my tongue in seconds and seem to work much faster than the capsules I used to take. I feel a noticeable sense of calm about 20 minutes after taking one, which helps me unwind and fall asleep so much easier. I love that there are no fillers and that I don't even need water to take them.

I loved how fast the order was shipped. The product quality was excellent. My sleep quality good way better when using this Gaba extract, what caused my energy levels increase. Taste is neutral. Packaging is optimal. I really like that composition of ingredients in this supplement was without unnecessary toxic ingredients.

Instant Dissolve MicroLingual® Tablets may be small but they are full potency! Typical tablets and capsules need to be swallowed and are inefficiently absorbed in the digestive system. MicroLingual® tablets dissolve immediately under the tongue heading straight into the body. Our proprietary hydrodrying process results in fewer inactive binders and fillers and a higher ratio of nutritional ingredients—hence the small size. They efficiently provide your body with the nutrients you need right now.
