Review: Great for 3 AM wakeups - I’ve been struggling with waking up at 3:00 AM and not being able to fall back asleep for hours. I decided to try this, and it actually worked in about 10–20 minutes! The key is following the instructions: don’t swallow it right away. You have to keep it in your mouth for 60–90 seconds before swallowing so it can absorb properly. It’s made a huge difference in getting me back to sleep quickly without feeling groggy later. So glad I found this!
Review: Works for a little calming - This product helps noticeably but be aware that OTC supplements cannot match GABAergic prescription medications. If you need a little calming, Quicksilver's product is good. If you need to stop neural firing, you need a prescription drug.

## Features

- Transition to Tranquility - Life’s occasional stresses and mental strains can sometimes make it difficult to slumber soundly and through the night. GABA with L theanine is known to help calm without impairing cognition, support proper rest and offer brain support supplement benefits.*
- GABA Supplement - Naturally produced by the body, GABA is the premier ‘calm and connect’ neurotransmitter. It promotes balanced nerve transmission and nervous system support, while also acting as a supportive calm supplement.*
- L Theanine Supplement - A calming amino acid. After supplementing with L-Theanine brain support, brain wave patterns can smooth out, much like they do with meditation. Contains L-theanine 100 mg.*
- Unsurpassed Absorption - Typical oral GABA supplements have very poor bioavailability. Quicksilver liposomal absorption technology delivers both GABA and L-theanine faster and more efficiently.*
- Superior Liposomal Supplements for Calm & Brain Support - Some liposomal products use large, less effective liposomes of 200-1000 nanometers. Our liposomes are 20-100 nanometers, offering superior effectiveness and bioavailability.*
