  • Supports Cardiovascular Function
  • Promotes Relaxation
  • Vegetarian/Vegan


L-Theanine is an amino acid naturally found in green tea.  L-Theanine promotes relaxation without the drowsiness or negative side effects associated with other calming agents.  L-Theanine also supports healthy cardiovascular function through this relaxing effect as well as its antioxidant properties. L-theanine reduces stress and relaxes your brain by increasing alpha wave activity. Alpha waves are those that occur when you are awake, alert and relaxed. They help you to concentrate and promote creativity.

L-theanine, which exerts its stress-reducing effects without causing drowsiness, is also able to cross the blood-brain barrier, a protective filter that prevents some compounds from reaching the brain, making it a good potential alternative for certain anti-anxiety medications. L-theanine prevents damage to brain cells by blocking overstimulation of the cells and protects brain cells from being impaired when oxygen levels are low. It also promotes production of new brain cells by stimulating release of a protein necessary for nerve growth.

Antioxidant effects of L-theanine provide benefits for the cardiovascular system by preventing oxidation of low-density lipoprotein, or LDL, cholesterol. Researchers of a tissue culture study published in the July 2012 issue of the "Journal of Nutritional Biochemistry" found that L-theanine improves cardiovascular health by promoting production of nitric oxide, a compound that causes blood vessel dilation, in the linings of arteries. In this way, L-theanine may reduce blood pressure and decrease risk for cardiovascular disease.

L-theanine is a powerful stress and anxiety reliever. It effectively reduces both, mental and physical, stress. About 30-40 minutes after ingestion, it induces tranquility and a state of deep relaxation without causing any drowsiness or forming a chemical dependence. In fact, it helps to improve attention and concentration. L-theanine is one of the few known substances that easily cross the blood-brain barrier. It exerts subtle changes in the brain chemistry by altering the levels of serotonin, dopamine, and GABA.

L-theanine induces state of well-being and relaxation in different ways:

  • it stimulates the production of alpha waves in the brain.

  • it increases the levels of the inhibitory neurotransmitter GABA in the brain.

  • it lowers the blood pressure.

  • reduces heart rate.

  • alleviates depression.

  • supports concentration and mental performance.

  • helps focus attention on critical tasks.

  • improves learning.

  • protects the body from stress damage caused by the hormone cortisol.

  • improves quality of sleep when taken 30 minutes before bed.

  • protects the brain from damage done by glutamate and caffeine.

  • supports the immune system by increasing the activity of T-cells.

  • assists in weight loss by promoting thermogenesis.

  • reduces levels of lipids in the blood.

  • lowers blood pressure in people with a high blood pressure.

  • relieves physical and mental symptoms of PMS.

  • protects the liver from damage caused by alcohol.

L-theanine is a versatile natural supplement that helps to restore the balance in the mind and the body. It has no known side effects. It relaxes, restores mood, and rejuvenates.

 Green tea has been recognized for centuries as having relaxant properties. l-Theanine, a unique amino acid derived from tea, provides the characteristic taste of green tea. l-Theanine has also been discovered as the biologically active constituent of green tea responsible for promoting relaxation. In a preliminary non-clinical study, an l-theanine solution enhanced alpha wave production in the occipital and parietal regions of the brains of volunteers. These observed patterns are considered to be an index of relaxation. Furthermore, it did so rapidly and without causing drowsiness. In two additional studies, alpha waves were also shown to be detectable soon after l-theanine administration. Theanine is also useful for supporting healthy cellular function. Preliminary research suggests that l-theanine may be helpful for premenstrual support including healthy attitude. Furthermore, theanine has been reported to moderate the effects of caffeine on the central nervous system. l-Theanine's safety is supported in studies and by its long history of safe consumption in tea.
