    My family find this effective when we can't sleep. I've also recommended it to others who are going through anxious times eg prior to taking a driving test, during menopause etc

    Seems to be good quality. I experienced an energizing, motivating and calming effect as well as reducing anxiety. Im about to buy some more.

    Elthea is great for taking on stressful days or on sleepless nights. Relief is felt quickly especially when a capsule is opened and emptied on to the tongue! My husband and I would not be with out it.

Product Description
  • Help to manage stress naturally
  • Promote relaxation without drowsiness
  • Patented pure form of L-theanine
  • Suitable for Vegetarians & Vegans

Hadley Wood Elthea-100 contains the original SunTheanine™ which is the product of a Japanese manufacturer and is standardised to 99% L-theanine. In a study comparing five other L-theanine supplements, SunTheanine™ was found to be the only one that was nearly pure L-theanine.

L-theanine is an amino acid that we can find naturally in green tea, which seems to have anti-stress, anti-depressant, neuroprotective, and cognitive performance-enhancing properties.

Like a relaxing cup of green tea, L-theanine works really fast as it is easily absorbed and reaches maximum concentration within 30 minutes to 2 hours of intake.

This amino acid fosters a restful, relaxed state without diminishing daytime alertness and promotes calmness and well-being without drowsiness.
