This review is based on one day of use, not accounting for any potential adaptation that may have developed, and subsequent diminished effectiveness. Product is amazing, not the same as nervine GABAnergic herbs like Valerian or Lemon Balm. Although the general consensus on the internet seems to assert this Amino Acid molecule is too big to diffuse into the blood brain barrier, and increase output of GABA as a neurotransmitter, what I feel now isn't a placebo. Im calm but not sedated, there's no hesitancy to speak in public, there's a go with the flow vibe in my mind, rather than my default trepidation. I don't know if this stuff is for you, but in my experience, on my first day, I believe some or maybe all of this crossed my brain.

I take this for flare-ups with my fibromyalgia and it works wonders. I take 2 capsules up to 4 times a day and it provides lasting relief. I like that it doesn't give me any side effects like prescription meds for fibromyalgia do, and I find that I don't have to take it all the time, only when it gets bad. I'd strongly recommend this.

Gaba is a great product (helps with menopause related nightmares and anxiety). This is the brand my Naturopath gave me. I repurchased a couple times but have found that other brands work just fine too. This brand is bit pricey.

I use GABA to help anxiety and this brand is very good. No side effects noticed either. I would recommend it.

it worked like a miracle then i habituated to it when used regularly so use it only when really need it like natural valium

I fell in love with this company's St. John's Wort oh my lord it had me feeling like a relaxed slug lol (which, incidentally, disappeared from being able to purchase it anywhere anymore) and I decided to try the GABA (I already had supplements from a few other companies that I swore by and wanted to add more of this supplement to my stack). I take one capsule in the evening and notice no difference whatsoever in my mood. Now, when I take Natural Vitality CALM Lavender & Lemonbalm (after work) - that right there is tried and true! But later on before bed when I take this along with a Valerian Root? Nothing happens. No mood change. No sleepiness, no relaxation, just... nothing. I'm just sitting there. From what I've read 750mg is way more than enough GABA to have some sort of effect - but sadly I've not experienced anything with this one and I have taken the whole bottle aside from 4 capsules before doing this review. Will not be repurchasing.
