LOVE, LOVE THESE LITTLE WHITE CAPSULES! They really help me stay calm and focus during stressful situations at work. I take one every day, but on really stressful days I take 3. I gave a few to my sister who is currently under a lot of stress seeking employment. She was so impressed, she went out and bought a bottle at a local health food store for 3 times the price i paid on iHerb.

Alpha state

Take it on an empty stomach. Great for getting you to an alert state but not agitated.

Very Good Buy

This is an excellent product for a very good price. I notice I am calmer and sleeping better after one week of taking this patented l-theanine formula.

Seems to work pretty well

I didn't notice how well this stuff worked until I forgot to take it one day and turned into kind of a space ace. Suntheanine is supposed to be more effective than regular plain L-Theanine. I've tried both and I suppose it is a little better.

Suntheanine is the best

Very good product at a great price. At 150mg it is a perfect quantity for me to take morning and night. Im sleeping better, calm and relaxed during the day and with great focus and attention.

Noticeably reduces the irritating effects of caffeine.

Worth every Penny. I have been suffering from ADHD for a long time now and am using this instead of medication. I just wish there are high dosage capsules for the more serious conditions like mine

Balancing Neurotransmitters.

Posted by Reviewer2849284 on Apr 14, 2015

I recently removed the 5-HTP from my supplement line-up because I was exhibiting signs of too much serotonin. L-Theanine is a precursor to other neurotransmitters and seems to be useful and have a balancing effect, especially for those of us with fibromyalgia.
