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. ### ⭐⭐⭐⭐⭐ Working L-THEANINE *by on Reviewed in the United Kingdom 13 May 2019* This is second time I have purchased an L-THEANINE supplement. Having recently tried an alternative brand at a lower 200mg dose, stacking it alongside a morning espresso to take the edge off any negative caffeine effects.This FS L-THEANINE has had a much more powerful effect for me personally than the first supplement I tried from a different company, possibly due to a 300mg dose per capsule.I have taken as much as 900mg on an evening just before getting into a hot Epsom Salts bath and it induces the most calming sleepy effect on me (As opposed to just taking an Epsom Salts bath without the L-THEANINE) I have had ZERO negative side effects since taking this product.I recently watched a YouTube video on the benefits of L-THEANINE, including why Green Tea drinkers experience no jitters compared to Coffee consumers.I highly recommend taking an L-THEANINE capsule alongside a coffee to give you mental focus, it's worked a treat for me.On the back of this I would now be happy to try a different supplement from FS having been incredibly impressed with their L-THEANINE offering. ### ⭐⭐⭐⭐ Good but pricey *by on Reviewed in the United Kingdom 9 July 2024* Good quality and results, it does calm me down through the day but a bit expensive to maintain, I've changed to similar and cheaper. ## Frequently Bought Together - FS L Theanine | 180 L-Theanine Capsules from Green Tea - High Strength 750mg Green Tea Extract Providing 300mg L'theanine per Serving | L Theanine Supplement | Non-GMO Gluten Free | Made in UK - FS Magnesium Glycinate | 180 Magnesium Glycinate Supplements - 250mg Mag Bisglycinate per Serving | High Strength Capsules | Non-GMO & Allergen Free | Made in The UK - Omega 3 Fish Oil 2000mg, EPA 660mg DHA 440mg per Daily Serving. 120 Capsules (2 Months Supply).
