Calming and Effective Without Making You Sleepy
The L-Theanine 400 mg worked really well for stress and tension. I felt calmer and more focused within about 30–40 minutes, but not drowsy at all. It’s great for staying relaxed during work or before bed. The capsules are easy to swallow and don’t upset the stomach. A solid extra-strength option if you want gentle, natural stress relief.

It actually works ✅
I have ADHD and it's very hard for me to settle my mind down to go to sleep. Also, I have sleep apnea.. When I say I take it an hour before bed and don't wake up. What a blessing 🙏🏽 Before taking this. I use to toss and turn all night. Also. I would wake up easily to any sound. All of that went out of the window taking this. I take two one hour before bed .. and sleep 8 hours.. I have bought this 6 times and I am going to keep refilling my order
