The supplement facts listed on their website now shows it at 1 gram as well.
If you want to add extra GABA to it, we offer a GABA Powder - 300 grams at a great price. We just released it a couple of weeks ago and I don't think its been ordered yet by any of our UK retailers, but hopefully it will be soon.
Which ones do you normally order from? You can pm me if you prefer to talk that way. I'm working today so was just going to offer to send them an email asking how soon they'd be ordering it.
