Supplement Description

L-Theanine is an amino acid found predominantly in tea.  When you have a stressful moment or a shock a 'cup of tea' one of the first things that come to mind but why? The reason is thought to be L-Theanine which is believed to promote a calming and relaxing influence.

If you are a coffee drinker it's likely that at some point you will have drunk too much and experienced a 'hyper' effect.  It is very doubtful that you have ever experienced the same thing with tea even though it contains a lot of caffeine and the reason why is thought to be theanine. It is thought that theanine works to offset caffeine's effect but without causing any drowsiness. It is also a supplement which is not known to be addictive.

Pure, strong and high grade material

Service Rating: Ik sta altijd versteld hoe snel de bestelling vanuit Engeland hier in Nederland is. Maar een of twee werkdagen extra ten opzichte van een bestelling in Nederland zelf. Product: Hier in Nederland gaat het vaak om capsules van 100mg. Plus hier in Nederland zijn de prijzen een stuk hoger. Ik bestel meestal tweemaal de hoeveelheid (2x 120 caps), dat scheelt al weer een beetje in de portikosten.
Service Rating: Good products Product: Good products thanks very much

I also advised my daughter to buy them. She has MS and thinks that they are the main reason she can cope with her illness and all of its ramifications.
