Product Details

L-theanine, an amino acid found in green tea, has a reputation for its calming and relaxing effects. This theanine supplement supports mood and fights stress in a few different ways. It promotes relaxation by supporting a healthy stress response, encourages brainwave patterns that are similar to the effects of meditation, and encourages the production of GABA, a neurotransmitter that influences levels of the feel-good neurotransmitters dopamine and serotonin. The theanine used in this L-theanine supplement contains the pure form of this amino acid, delivering 100 mg of L-theanine and is non-GMO, gluten-free and vegetarian.

Promotes relaxation – If you’ve felt the calming effects of green tea, thank theanine! Found in green tea, it’s one of the best-known amino acids for stress— and for good reason. This supplement supports a healthy stress response to maintain your zen. Calming brainwave patterns – L-theanine helps modulate several different aspects of brain activity for mood support. This supplement promotes specific brainwave patterns similar to those associated with performing meditation or getting a massage. Neurotransmitter production – The neurotransmitter gamma amino butyric acid (GABA) plays a role in influencing healthy levels of the feel-good neurotransmitters dopamine and serotonin. L-theanine helps encourage GABA production, to keep that feel-good feeling going. Ingredients matter – We use only the finest raw ingredients with the purity and potency you deserve. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every one.

I've been taking this a couple years now. It definitely helps, it puts you on an even keel. I started out taking 1 twice a day and that really zapped my energy. I went down to just once at bedtime, and found my comfort zone! I recommend this for everyone!

This stuff definitely stabilizes your mood and emotions! I've been taking it a couple years now. I started taking 2 a day in the beginning, but was feeling tired so I cut back to 1 @ bedtime, and it really helps me sleep and feel just fine throughout the day.

Taking alone won't help, I've to take other supplements to get me to sleep and generally it works after taking 1 1/2 hours. I fall sleep rather fast (15-30 minutes) and reach REM & deep sleep over an hour each.

I am so happy that my mom recommended this product to me. It has helped me to sleep most of the night. #sweepstakes. Before taking L-Theanine, I felt as if I were up most of the hours during the night especially since starting menopause. I take two of these a few hours before bedtime and am able to drift off to sleep and wake up with my alarm. Also, I feel less stressed at work during our busy time. All in all, I have had good benefits from taking this product.
