1. Background

L-Theanine is an amino acid found in green tea leaves, and is one of nature’s most effective natural relaxants. AlphaWave® L-Theanine is produced through a proprietary fermentation process that results in a highly purified form of the amino acid. Today, the reason for AlphaWave®’s growing consumer demand is that when people take it, they feel a difference. AlphaWave® directly stimulates the production of alpha brain waves, creating a state of deep relaxation and focused energy. Through the recent clinical study on the effects of AlphaWave®, and other studies with L-Theanine, it carries the following S/F claims:

  • Helps relax without drowsiness
  • Promotes mental clarity and focus
  • Promotes learning and memory
  • Reduces nervous tension

2. Clinical Study Confirms the Benefits of AlphaWave® L-Theanine

‘The Effects of AlphaWave® L-Theanine on Relaxation, Clarity and Cognitive Function: a Human Study w/20 Subjects’

AlphaWave® is now supported by a double blind, placebo controlled human study conducted at: The Wellington Sleep Investigation Centre, University of Otego, Wellington, New Zealand.

Key study findings were:

  • AlphaWave® consumption produced significant changes as compared to placebo on all the variable outcomes assessed in this investigation.
  • AlphaWave® showed (by EEG) a positive effect on the tonic alpha power that measures relaxed wakefulness.
  • Values for anxiety and tension decreased greater than placebo.
  • Reduced fatigue.
  • Reduced heart rate, an indication of stress reduction.

Please note: A copy of the full study is available on request. A second supporting study is now underway at KGK Science.

3. Additional Data Supporting L-Theanine as a relaxant

Studies found that L-Theanine is able to cross the blood-brain barrier, and thus has psychoactive properties [1]. Clinical trials confirmed L-Theanine has relaxing properties [1]. The calming effect from tea may seem contradictory to the stimulatory property of its caffeine content, but this effect is explained by the action of L-Theanine, which acts antagonistically against the stimulatory effects of caffeine on the nervous system [2]. Research on human volunteers has demonstrated that L-Theanine creates a sense of relaxation via at least two different mechanisms. First, it directly stimulates the production of alpha brain waves, creating a state of deep relaxation and mental alertness similar to what is achieved through meditation.

Second, L-Theanine is involved in the formation of the inhibitory neurotransmitter, gamma amino butyric acid (GABA). GABA influences the levels of two other neurotransmitters, dopamine and serotonin, also producing key relaxing effects [3]. Furthermore, L-Theanine has been shown to reduce mental and physical stress [4], and improves cognition and mood in a synergistic manner with caffeine [5).

4. AlphaWave® is GRAS Affirmed, confirming its safe use in supplements and beverages

  • Highly purified and standardized to 98% L-Theanines
  • Excellent tableting and encapsulation qualities
  • GRAS Affirmed
  • Dissolves into tasteless and odorless solution for beverage use
  • Proprietary manufacturing process infringes no patents

5. AlphaWave® and L-Theanine patent issues

There are seven current US patents that cover different aspects of manufacturing methods, forms and uses of L-Theanine. These are largely owned by Taiyo Inc. (Japan). A full review of each of these patents by a US patent attorney confirms that the AlphaWave® manufacturing and recommended use methods do not infringe any of these patents. Summaries and detailed reviews can be made available to potential AlphaWave® users.
