L-Theanine-What's it all about?

L-Theanine is a buzz word, everyone is talking about it.  L-Theanine is a naturally occurring amino acid most commonly found in tea especially green tea. Its main benefits are to help reduce stress and anxiety, and at the same time improve focus and attention. It may help to improve sleep by promoting relaxation before bedtime. Some of you might remember the Lyons Tea advert that highlighted the calming yet focus-enhancing properties of their tea. The advert emphasised how the tea could “promotes a state of relaxed alertness,” that sounds great doesn’t it? And that is exactly what many people use it for, relaxation with focus.

L-Theanine is an ideal supplement to consider when you need help to deal with stressful situations. It is a supplement to consider when you need help calming the mind so you can relax. It is useful for periods of times where you are experiencing high levels of anxiety.  Stress and anxiety can cause your brain to go blank, you may find that you cannot think straight, or you can't focus, L-Theanine can help. There may be so many thoughts going around in your head that your head simply feels full, L-Theanine may help slow them down so you can make sense of them.  It can aid sleep by supporting relaxation and calming the mind. The stress and anxiety can come from anywhere or anxiety can have no reason at all. Generally, it could be at home, in work, school, college, medical, or relationships. These are just a few examples of how L-Theanine might help you.

How much L-Theanine can I take?

Most brands will recommend up to 400mg per day. You can take L-Theanine by itself in supplement form or you will find many combination supplements to support your needs.

If you already take Magnesium, B Vitamins or fish oils it will work perfectly well with any of these, they would all complement each other. There are several supplements that contain a mixture of ingredients this will vary depending on whether they are targeting stress/anxiety or sleep.

For example, if you want to improve the quality of your sleep then I would look at New Nordic Melissa Dream. It combines Magnesium, Chamomile, and B vitamins with Green Tea (standardised to 30% L-theanine) and Lemon Balm which helps to find sleep, to help you switch off your busy/frazzled mind and support relaxation so you can get off to sleep faster. It doesn’t cause drowsiness, in fact it should help you to be more alert and focussed the next day.

If you need something for stress/anxiety or a busy mind then take a look at Higher Nature Balance for Nerves. It contains L-Theanine, Magnesium, and B Vitamins but this one also includes the relaxing herb Passiflora/Passion Fruit which is an amazing herb to support relaxation and has a lovely calming effect. We have been in business for over ten years now and  this is one of the first supplements that we worked with for customers experiencing high levels of anxiety. It remains a popular supplement with us today.

You may prefer to try L-Theanine on its own without anything else, take a look at Pure Encapsulation L-Theanine each capsule contains 200mg. This is a popular brand known for its high quality researched back supplements.
