luke h on 25/08/2026Verified buyer
I find L-Theanine the perfect addition on really stressful days when I need the relaxation of a cup of tea but dont want to take caffeine so i take it alongside herbal or decaffeinated teas.

its good
A simple addition that transformed my evenings
Sheetal T on 25/07/2026Verified buyer
I started taking this L-Theanine in June and it’s become a key part of my evening routine. Managing ADHD with Vyvanse is great during the day, but winding down at night used to be tough. I take 1/4 teaspoon in sparkling water around 6-7 PM which makes a huge difference. It doesn't make me groggy, but gently takes the edge off and helps quiet my mind so I can easily transition into bedtime mode. I'm also focusing on overall wellness and mitochondrial support right now, and this fits in seamlessly. It's been a wonderful addition to my daily health regimen!
L theanine
Andrea M on 24/07/2026Verified buyer
Purchased to try out the quality and I'm happy. I was buying it overseas and it was cheaper but postage was more, I'd tried bioglan brand in caps which was rubbish and this has good effect within 20mins. I take high doses at night to sleep
Relaxing and rejuvenating.
Cyril B on 13/07/2026Verified buyer
Like the title says, since discovering the benefits of L Theanine, it's my go to remedy for stress relief safely. I highly recommend bulk Nutrients product.
