A natural anti-stress solution

L-theanine supplement, is an amino acid found in green tea that easily crosses the blood-brain barrier, and produces calming effects in the brain comparable to those induced by massage, meditation and aromatherapy. As you would need to drink 10 to 40 cups of green tea a day to obtain an active dose of l-theanine, supplementation offers a preferable option.

Why take L-Theanine?

It is estimated that 65% of adults are affected by various forms of stress and the number is rising. Almost 70% of adults suffer from sleep problems of one form or another. These problems, which often remain undiagnosed and untreated, can have such harmful effects on biochemical parameters and on short, medium and long-term health that stress is often termed the invisible killer'.

What are the benefits associated to L-Theanine capsules?

  • L-theanine induces relaxation without causing drowsiness, an effect which can be measured by increased alpha waves in the brain.
  • In fact, studies show that it even improves the brain's ability to concentrate, learn and memorise. In Japan, chewing gum, ice cream and soft drinks fortified with l-theanine are included on the menu for students during exam periods.
  • Unlike caffeine, l-theanine raises brain levels of GABA (gamma-amino butyric acid), an inhibitory neurotransmitter which induces relaxation and promotes a feeling of well-being.
  • L-theanine also increases brain levels of both dopamine, the pleasure and reward' neurotransmitter, and of serotonin, the main inhibitory neurotransmitter, both of which are severely compromised in situations of stress and overwork.
  • Studies show that l-theanine offers additional health benefits: it protects the brain from glutamate-induced neuro-toxicity, a major cause of neurodegenerative disease.
  • It significantly reduces mental, physical and social symptoms of PMS.
  • It regulates blood pressure and helps temper the unwelcome effects of caffeine.
  • According to a recent study conducted at the National Institute of Mental Health in Japan, 200 mg of l-theanine taken before bed improves sleep quality to such an extent that participants all awoke feeling “more rested” after a “more effective” sleep, without necessarily sleeping for longer. Subjects also reported waking up easily in the morning, feeling alert and refreshed instead of groggy.
