L-theanine: A Modern Panacea?

We can all envision that relaxed sigh from the first sip from a nice cup of tea. Why is tea so relaxing? Research suggests that the calming properties of tea are partly due to L-theanine, an amino-acid constituent of tea which is commonly used for anxiety relief.

Today, renown cancer care specialist Dr Lise Alschuler takes us through the diverse range of conditions for which L-theanine may be useful from the more obvious uses such as anxiety, insomnia, ADHD and learning, through to emerging uses including immunity, cardiovascular health and promising applications for co-therapy with chemotherapy.

It seems that the therapeutic actions of L-theanine are congruent with the demands of some of our most common chronic health issues, making us pose the question:

is L-theanine the panacea to modern life?
