L-Theanine 400mg from Green Tea - 90 Vegan Capsules - Amino Acid Supplement – Resealable and Recyclable Pouch by Alpha01

I have been taking these now for 4 months and i do believe my concentration has improved. I feel more awake at work and able to think. My only issue with these is that my most recent pack seem yo have a smell and taste which they did not have before. It’s not the end of the world but also not overly pleasant but given the effectiveness and cost i will keep buying. I have digestion issues and haven’t seen a difference taking these so i don’t think they cause any issues or irritation personally. I would recommend this brand

Excellent quality, have been taking daily for over a year now and it really works to lower my anxiety especially in social situations and in work

They definitely seem to help with my mind racing away, relaxing me somewhat, and allowing me to have a more peaceful sleep. Definitely worth a go.

Brilliant and really worked on the first night. Fell asleep no problem. Brilliant result. The reason I've given it 4 stars is it once I opened the packet, the bag smells like maggots (when I used to go fishing) but I'll continue to buy as they do the job. 👍

good price for the amount. Easy swallow

I have taken l-theanine from this brand for over a year and found it to be of excellent value and quality. The last batch I ordered I have noticed they have changed the product and formulation. It's no longer organic, and now contains a less concentrated extract. Moreover it smells vile. I used to empty the content of the capsule into a small amount of water and take in the morning. I can't possibly drink this new version, it smells so awful it made me feel sick, so I'm having to throw it away and switch to another brand. What a shame.

Took these hoping for a bit of calm, and they genuinely take the edge off without turning me into a zombie. It’s like someone gently lowered the volume on my brain. Smooth, steady, and no weird side effects — just a quiet little “shhh” for the mind.

I gave this product 3 ⭐️ as overall I do feel better since taking these but that also coincides with taking a new HRT prescription (patch). Before these & the HRT patch I was a dipsy dolly day dream with occasional anger issues (never violent) & in a perpetual state of not being able to think clearly/decisively & a lot of anxiety thrown in to boot. It felt like someone had pressed the stop button on my thinking/processing/rationalising brain function. But 6 or so months on I feel more able to function & think in situations/conversations pretty much as I did before the menopause hit. I can actually walk into my office now & be decisive about what needs to be done whereas before I physically wouldn’t be able to think & was completely overwhelmed. So I will carry on taking. They are very easy to swallow with no taste & no side effects.
