Work great!
The tablets really work. In about 10-15 minutes after chewing them, I feel my stress level drop and I even out.

Great to calm the nerves
Love this brand for L theanine. I take this when I have that inner tension/ inner anxiety that I can’t shake off. It’s great to take while drinking coffee to take the edge off or jitters from the caffeine. I have ADHD and helps with calming the mind to help focus. Use it mainly during the day but can be used at night.

Shuts off brain so you can sleep.
I’ve had the worst insomnia for the last week or so. Nothing helped; not even my prescription sleep aid. I tried adding glycine, tryptophan, GABA, melatonin (with lavender and chamomile), and even Xanax but nothing helped. I was averaging maybe two hours of sleep each night. I ordered this sun theanine chewable hoping it would help and it did. I took one chewable with my prescription sleep aid at 9pm. I started to feel a little sleepy but still not actually falling asleep yet. Although I was watching Netflix and that keeps me from falling asleep too. I looked at the clock and it was 11:30PM I decided to take another chewable sun theanine along with 1 chewable MidNite Melatonin and shut off my iPad. For the first time in a week or so I slept like a rock. I’m feeling a little hungover/groggy/super chill so I think either the extra melatonin or Sun Theanine tablet might have been too much. At least if I want to get out of bed and do anything. Tonight I will experiment with either 2 Sun Theanine or 1 Sun Theanine and 1 MidNite melatonin (only 1mg of melatonin). Again, I’m taking a prescription sleep aid with this, so effects may be different but all I can say is my prescription was not helping me fall sleep the last two weeks until I took this. Usually my prescription works to help me sleep, but have been under a lot stress last couple weeks. I feel like this Sun Theanine Chewable helps to shut off my brain and get rid of racing thoughts so I can sleep. These really work. They taste great too. Not too sweet or tart. I feel like it’s a little pricey, but I guess you get what you pay for.

It’s very effective. You can chew or suck on the candy very quickly until it dissolves. You will feel more calm within a few minutes. I find these candies extremely helpful in certain situations to help me calm down and stay focussed. I highly recommend them!

We like the results and the taste

I have used this in the past when life gets too hectic. It works for me so I had my daughter try it. She ran out a couple weeks ago and said she could tell the difference and needed to get back on it so I ordered her another bottle. Best price was here on Amazon
Bonnie –
My husband passed away recently and I was having a hard time going to sleep. I do feel these are helping. I did not want to go onto prescription drugs, these are an excellent replacement.
