  • Double potency L-theanine supplement



  • Delivers 200 mg per capsule, an important amount supported by clinical research



  • Promotes calm, balanced mental health and emotional well-being


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 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. Our new Double Potency Suntheanine L-Theanine delivers 200 mg per capsule, the upper limit shown to produce results in clinical research.

Rated 5 out of 5 by from 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"

Rated 5 out of 5 by from Focus & Calmness. I take it in the morning everyday with my cup of coffee and GABA. If you're one those people like me who has rest issues...your brain won't work & you're cranky in the morning...this is a God-send. You have your energy(coffee), focus(L-theanine), and calmness(GABA) all together. Been doing it for about 3 yrs now and will never stop. Swanson sells both. (buy me coffee at Walmart :)

Rated 5 out of 5 by from Reliable I have used this product for many years. It has a calming affect without interfering with cognitive function. And no side effects.

Rated 5 out of 5 by from Suntheanine For Sleep I am a working woman in my mid-50's and sometimes I will wake up at 2:00 in the morning and have trouble getting back to sleep. I read that Suntheanine is the relaxing component in tea. Not wanting to drink several cups of tea in the middle of the night, I decided to try these capsules and I have been pleasantly surprised by the results. Within 1/2 hour I am relaxed and sleepy enough to fall back asleep and I feel very refreshed when I wake up. I would recommend this product to anyone.
