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.

Lamberts L-Theanine is the purest form available and is the one used in clinical studies.

Our L-Theanine is painstakingly produced by a process of fermentation.

We do not use L-Theanine extracted from tea as this contains a high proportion of D-Theanine which is not believed to be as active as the L-Theanine form.

Better still, we have just increased the potency of this product to 200mg for the original 100mg price.
