| If you have bought anything for sleep in the last two years, you have bought GABA. Those three letters are printed on gummies, calm drinks, powder sticks and half the cans in the functional beverage cooler. Almost none of them will tell you how much is in there. The device that hides it is the **proprietary blend**: one total figure for six ingredients, and a number for none of them. And there is a second line ready if you push. Oral GABA cannot cross the blood-brain barrier anyway, they say, so the dose hardly matters. Convenient, that. If it fails, the dose was never the promise. If it works, they never had to print one. The GABA never failed you. You were simply never handed the amount that was tested. THE BRAKE PEDAL IN YOUR HEAD GABA is your brain's main inhibitory neurotransmitter. Glutamate is the accelerator, GABA is the brake. Every sleeping pill ever written onto a prescription pad works by standing on that same pedal, and so does alcohol. The blood-brain barrier point is real, and it is half the story. Swallowed GABA does not flood your brain. What it does reach is the **enteric nervous system**, the dense sheet of nerves lining your gut, which reports upward through the vagus nerve. You are not filling the brain. You are sending it a message from below. THE EVIDENCE Jung Ick Byun and Won Chul Shin at Kyung Hee University Hospital in Seoul gave 40 people with insomnia **300 mg** of GABA from fermented rice germ, one hour before bed, for four weeks (*Journal of Clinical Neurology*, 2018). Time to fall asleep fell from 13.4 minutes to 5.7\. Sleep efficiency climbed from 79% to 86%. The placebo group did neither. Four weeks. Not one night. That single detail is where most of these bottles end up in the bin. TONIGHT, IN ORDER OF EFFORT THE LABEL CHECK (FREE) Go and find the GABA number on the bottle you already own. If it sits inside a proprietary blend, there is no number, and no way to know whether you swallowed 20 mg or 200\. A formula that will not print its dose was never built to be measured against anything. THE 300 MG RULE Copy the trial: 300 mg, one hour before bed. That is the dose with overnight sleep recordings behind it, and a single-ingredient capsule costs a few cents a night. The same group later tested 75 mg and that held up too, so start at the low end if you would rather be cautious. THE FERMENTED FORM Look for fermented rice germ, not plain synthetic GABA. The trials that measured actual sleep outcomes used the fermented kind. Synthetic is cheaper to produce and it is what fills most gummies. Three identical letters on the front of the pack, and a different thing inside the capsule. THE 28-NIGHT RULE Give it twenty-eight nights before you pass judgment. That trial measured its result at four weeks, not after one hopeful Tuesday. Four of the forty reported stomach discomfort or a headache, so if that turns out to be you, stop and put it down. Otherwise judge it at the end of the month. And one more thing... There is a second way onto that pedal, and it comes at the problem from behind. **Valerian root** does not add GABA to the system. It slows the enzyme that clears GABA away, so what your own brain already made stays in play longer. Used for restless nights since ancient Greece, it smells appalling, and no company on earth can patent a root. Which is precisely why it shows up as the fourth name in a blend instead of alone, with a dose you could read. QUICK QUESTION Does your sleep supplement print an actual GABA number on the label? [YES](mailto:Claire%20Ashton%20%3Cmeloucou@gmail.com%3E?subject=Yes%20-%20There%27s%20A%20Number&body=Yes%2C%20here%27s%20the%20dose%20on%20my%20label.)
