Review: Best L-Theanine supplement I have tried - I have been using L-Theanine for around 8 months now. I first tried 200mg and found that though there was a difference, it wasn’t enough. I moved on to 250mg and felt the same way. After this there seemed only to be 400mg, which seemed like too much. But then I found Focus Supplements had made a 300mg supplement, and after taking it I found that this is the perfect dosage. I have been using this particular brand of L Theanine for 2-3 months and I couldn’t be happier. They are tasteless, relatively easy to swallow, and a good price. But most of all they help... a lot. I take just one pill each morning and have found that my anxiety levels severely reduce for the rest of the day. No problems with sleep either, which is a bonus for me. I am very happy with these pills and don’t see the need to try any others given the changes I have experienced. It’s nice to be able to go outside once again without crippling feelings of anxiety. Review: Good to know - Silly me took this at night time and couldn’t sleep, only to realise it has also green tea not only l-theanine, so had to buy a different one however this does calm your anxiety abit during the day whilst getting your green tea extract benefits too. ## Features - HIGH STRENGTH L THEANINE - Each serving of 2 daily capsules provides 750mg Green Tea Extract Providing 300mg L-Theanine.
