Our daughter suffers with anxiety and anger outbursts. We have spent thousands of dollars on supplements. This is the only vitamin that we have purchased that has worked almost immediately. Our therapist recommended it. It has changed our lives and brought peace to our home. I just bought 5 bottles. Can’t thank this company enough. Signed happy mom and daughter.

I suffer from heavy bouts of depression and anxiety and since I started taking these daily, my flair ups of depression and crying episodes are nonexistant anymore. I don't agree with all the bill nye talk about the "placebo" effect since I was hardly even able to function before taking these due to heavy stress and anxiety. Now, even when I feel sad It isnt nearly as intense as it used to be and i can think rationally without a feeling of impending doom lingering about in my mind. I think the only drawback is the inevitable extreme sleepiness that comes with taking this, as well as most anti anxiety meds. I have to drink caffiene halfway through the day or i will be purely exhausted, but I think thats a fair trade for what I was feeling before. I can relax and enjoy a lot more normal activities instead of hiding away, and i feel more open to social situations now than before.

I mostly use this before bed, I take one capsule 1 hour before bed to help me fall asleep easier. This product definitely works, I feel it working within 5-10 minutes. I can feel a light fuzzy feeling in my head that brushes away any anxiety that Ive been feeling. I mostly get anxious during the night before bed, not being able to sleep gives me anxiety and it creates a vicious cycle. However this product has worked great for those random anxiety feelings. I sleep through the night as well. I do not know how it works in other settings but for me it's great for relaxing tension and getting a good night sleep.

My MD recommended this for anxiety. I take several in the AM with coffee in a technique known as stacking. I take several again in the evening after dinner as part of my wind down routine and sleep super well. Sun Theanine is the version distilled from green tea and he said it is more effective and reliable than other formulas.


I have suffered severe anxiety for a while now. I don't know why but it made me tired, unmotivated, sickly, and I would even faint. I decided I needed something to calm me because nothing worked. Prescriptions were too rough and I couldn't sleep all day. I saw this online and gave it a shot. I've been taking it every day for 2 weeks now and I haven't felt anxious or tired at all. THANK YOU SUNTHEANINE...!!!!
