Review: Good quality, taste great - This is a good brand and good quality. They did seem to calm me down and they taste delicious.
Review: Great for when I feel anxious - I have adhd and tend to feel anxious rather often. This was a game changer not just for my anxiety but for my focus and my sleep as well. If you're a caffiene addict and need something to level you out, this supplement took me out of those jitters and gave me focus, clarity, and calmed me back down. Great for right before bed to make that noise in your brain calm down. I don't feel any nausea with this product, easy to chew, and the flavor is good.

### ⭐⭐⭐⭐⭐ Chill pills and life savers
*by T***M on July 2, 2026*

I keep these stocked regularly. When going through divorce my EAP provider recommended these (alongside Gaba and 5htp but are great alone as well). I wanted something natural to avoid "anti depressants" or "anxiety " prescription bc ex would use that against me in custody talks. These delicious chewable tablets that taste like smarties candy are known to stop an anxiety attack within 30 minutes. They are safe, non drowsy, where obe can function at work without adverse affects. HIGHLY recommend
