Use for Sleep/Anxiety
Not quite sure if this works better or worse than any other l-theanine? I have been using l-theanine for some time, of various brands. I combine it with Natural Factors (Pharma)GABA for maximum efficacy. I haven't noticed any issues with this product.

More Info
Suntheanine L- Theanine
Suntheanine is the trade name for Taiyo's patented, pure form L-theanine. Distributed by Natural Factors, L-Theanine is an effective natural formula used to help deal with stress and anxiety.

It has been estimated that nearly 65 percent of the adult population experiences some form of stress, and these numbers are continually rising. Since ancient times, it has been said that drinking green tea induces relaxation. A pioneer in the science of green tea, Taiyo found this relaxation effect to be due to the presence of the amino acid L-theanine.

Human clinical trials have shown Suntheanine to promote an alert state of relaxation without drowsiness. Additional human clinical research suggests that Suntheanine may have applications in improving the quality of sleep, diminishing normal symptoms of premenstrual syndrome (PMS), improving learning performance, heightening mental acuity, promoting concentration, reducing negative side effects of caffeine and supporting the immune system.

This new 'feel-good' amino acid found in green tea produces tranquilizing effects in the brain without drowsiness. It calms by helping to increase alpha-brain waves, the electrical brain activity commonly present when you are very relaxed. By diminishing the feeling of stress, worry and anxiety, L-Theanine may actually help with focus, learning and concentration.

L-Theanine is very safe as attested to by the billions of green tea drinkers over thousands of years. It is estimated that a person who drinks 6 to 8 cups of green tea a day may consume between 200 to 400 mg of L-Theanine. Natural Factors new L-Theanine helps us benefit from this relaxing amino acid without having to drink pots of green tea every day.

You can help control anxiety and decrease stress by:



  • Taking a high quality B-complex supplement

  • Avoiding refined foods.

  • Avoiding foods and drinks high in sugar and caffeine.

  • Using deep breathing and meditation techniques regularly.

  • Exercising regularly.

  • Using herbs and supplements that support the nervous system and promote relaxation.

  • Maintaining regular sleeping patterns.
