Everyone knows that a nice cup of tea is the best thing for someone who has had some kind of shock or stressful ordeal. No other hot drink seems to offer this kind of support so there must be something in tea that has this calming effect. Tea certainly contains a surprising amount of caffeine and yet is not generally considered as a stimulant in the same way that coffee is. Some researchers think that this maybe because tea contains something else - in effect cancelling out the caffeine.The mystery ingredient in tea is now thought to be an amino acid called L-Theanine. Whilst it is not unique to tea, the tea plant seems a particularly rich source. When L-Theanine has been given to people in clinical studies many of the positive effects of tea can be reproduced.Ingredients - One tablet provides:L-Theanine 100mg OTHER Ingredients:Tableted with: Calcium Carbonate, Cellulose, Tablet Coating (Hydroxypropyl Methylcellulose, Colour: Titanium Dioxide, Glycerin), Silicon Dioxide, Stearic Acid, Magnesium Stearate.Directions Take 1 tablet daily with a meal.CAUTION: Do not take if pregnant or breast feeding.
