Description

L-theanine is an amino acid found almost exclusively in tea plants and, in particular, green tea. The pioneers at Taiyo International discovered that the relaxing properties of green tea may be tied to this unique nutrient and developed Suntheanine® L-theanine through a patented process designed to amplify its calming potential. Research indicates that Suntheanine stimulates alpha wave activity in the brain, which is associated with calm alertness. Swanson Suntheanine L-Theanine delivers 200 mg per capsule, the upper limit shown to produce results in clinical research.

Daily calm and sleep support

My favorite supplement! I take it every evening to help with sleep, and any time I’m feeling edgy or stressed throughout the day. It is a mild, pleasant feeling of calm and I see the best results with the suntheanine brand

Gentle, steady support

I’ve been using this L-theanine since the very beginning of my pregnancy and am now in my seventh month. I was looking for something mild to support mood and rest, without anything stimulating or dramatic. At first, the effects were subtle, but when I recently ran out, I clearly noticed the difference. It’s been gently supportive over time in a sustainable way. I appreciate having an option that feels mild, well tolerated, and appropriate for pregnancy. I plan to continue using it.

Great for Anxiety

This works way better than expected. I take it with coffee so I can keep a calm and focused feeling when the caffeine hits me.

The logical choice.

I like it. The double strength is more convenient to take - less pills, less bottles, As Spock would say 'it is only logical.'

Fantastic

I had read several articles on the benefits of L-Theanine used along with caffeine for a smoother energy surge. It works great!! Then I saw one that suggested taking L-Theanine at night helps promote relaxation and helps to turn off mind chatter. I have used before bed and when I have woken up and cannot go back to sleep with great success!! Will keep this stocked!!

ANXIETY, SLEEP, FOCUS

FANTASTIC supplement and good for the brain too. I have taken 1-2 during the day for anxious moments, 1 with my coffee to improve focus, and up to 4 at bedtime all without any side effects, just great results. I love having an alternative to pharmaceuticals!!!!!!

Great anxiety reducing producti

So thankful for this brand of LTheanine. I haven't found a better brand. I take one at night and if I feel anxious during the morning, I take one.

(no review title)

I have been using this for awhile and it is a good "sleep helper", but It doesn't make you sleepy so you can take it during the day too. Helps you "chill out"
