iHerb Customer Reviews

I take Suntheanine and Pharma GABA (specifically from Natural Factors) together when I am feeling stressed/anxious. I like the chewable tablets with their hint of sweetness. I find they work as a calmative - you don't feel better so much as less anxious. It's not a mood uplifter, really, you don't feel any different than you usually do, it's just that you are not as stressed. I particularly recommend it for people doing exams/interviews and I always use it when flying. Been using and recommending it for years and never had bad feedback.

Thanks for your feedback!

Helps my daughter with ADHD

Posted by iHerb Customer on Sep 17, 2017 | Verified Purchase

I have been using this for my daughter who has been diagnosed with ADHD and Anxiety. We started with one tablet in the morning and now we have moved onto 2 tablets in the morning and it lasts all day at school. She is so much calmer and can think more clearly at school. Just FYI we do not currently use any medication for her ADHD and she is also taking a multivitamin by Thorne research which we have noticed also helps way better than any other brand of multivitamin.

Thanks for your feedback!

Really surprised when I noted that there was no pill but a chewable tablet. Really like it! Right on the money. A wake me up morning.

Thanks for your feedback!

My experience with this one was good, but perhaps too relaxing... I save it for when I'm really stressed :)

Thanks for your feedback!

So far so good

The tablets are very large, and quite sweet.
