My Daily ADHD-Friendly Focus Support
I've been taking L-Theanine every morning on an empty stomach, and it's been a great experience. It's very gentle on the stomach and doesn't make me feel sick at all. I’ve noticed a nice boost in the mornings, less brain fog, and better focus and concentration throughout the day. As someone with ADHD who doesn’t take prescription medication, this has been a really helpful option. It genuinely works for me, and I highly recommend it!

Consistent Quality and Excellent Value
Solid product as always from Nutricost. The quality has been consistently good, and the 200mg dose is perfect without needing multiple capsules. Easy to take, no strange taste or side effects, and the 240-count bottle lasts a long time which makes it a great value. I’ve used several Nutricost products and they’ve always been dependable. Highly recommend if you’re looking for a quality L-Theanine supplement.

Calm and Focused Without Losing Edge
Nutricost’s L-Theanine has become a go-to for staying calm without crashing. The 200mg dose hits that perfect balance — enough to smooth out tension and overthinking, but not so much that you feel sleepy or slow. I’ve been pairing it with coffee in the morning and using it solo during high-stress afternoons. It keeps the mind sharp and anxiety in check. No jitters, no emotional fog — just calm, clean focus. The 240-count bottle is a solid value. One bottle lasts a long time, and every capsule has been consistent in quality. Pros: Smooths stress and promotes focus without drowsiness Pairs well with caffeine for balanced energy Noticeable effects within 30–60 minutes No weird taste or smell Excellent value for the capsule count Cons: Capsules are a little big — not a huge deal but worth noting Effects build with consistent use — don’t expect a miracle off one dose Bottom Line: If you’re looking for something that keeps you calm, focused, and steady — especially in high-pressure environments — this is one of the best tools out there. Clean, effective, and reliable.

Relaxing
I take this with magnesium at night and it helps me relax and fall asleep. Don’t expect any crazy effects like melatonin though.
