I purchased this supplement that contains Gaba, niacin and inositol. At first I tried taking it when I was feeling tense and anxious but it didnt seem to help, then I tried taking them earlier in the day when I was feeling relaxed and that seemed to do the trick at preventing attacks. So far so good, im hoping that it doesnt cause rebound anxiety in the long run. Its better than nothing at the moment.
Sorry to burst bubbles, but what you have is precisely nothing, plus some wishful thinking. Even if this supplement was able to deliver the GABA into your brain, and it probably can't, it wouldn't make a scrap of difference. Your brain doesn't lack GABA. As a byproduct of the Krebs cycle
(aka citric acid cycle) which converts glucose to Adenosine triphosphate, the main energy source of the brain, this organ is awash with GABA. So much of it in fact that the blood-brain-barrier has billions of tiny pumps to remove the stuff from the extracellular fluid into the bloodstream for elimination (Kakee A
What your brain lacks is benzodiazepine binding sites which potentiate GABA receptors and the ones it does have are less sensitive1
. Trying to overcome this by forcing even more GABA into the brain is akin to trying to overcome faulty spark plugs by filling the gas tank to overflowing. In both cases all you do is waste your money.
Unfortunately, nothing else does what the benzodiazepines (BZDs) do, not even the non BZD anti seizure drugs.
