You might have heard also of this important amino acid, although there are plenty of amino acids; in fact, there are around 20 of them.
You will find L-Theanine naturally in tea, and also as a supplement from your local health shop.
A few studies completed on L-Theanine show that just taking around 200 mg will have a calming effect on you, without causing you any drowsiness and if you just take around 50 mg; that’s about 2 cups of tea – you can increase your alpha-waves in your brain.
This is the part of the brain linked to creativity.
This amino acid becomes even more effective when you take it with caffeine, as mentioned above.
So you can imagine that the two are often used together to enhance performance and you will find them in supplements as well.
