NutricostL-Theanine 200mg, 120 Capsules, Double Strength - Non-GMO, Gluten Free

I've been on the hunt for something to help manage daily stress and improve focus without making me feel drowsy or "out of it," and after trying various supplements, L-Theanine has truly blown me away. This is, without a doubt, a 5-star product that has earned a permanent spot in my daily routine.From the very first dose, I noticed a subtle yet profound shift. It's not a dramatic jolt like caffeine, but rather a gentle wave of calm that washes over you. My often-racing thoughts become more organized, and I find myself able to tackle tasks with greater clarity and less internal chatter. It's like my brain finally has the "breathing room" it needs to perform optimally.What I particularly love is how it promotes a state of "alert relaxation." I can focus intently on work or complex problems without feeling jittery or anxious, which is a common side effect I've experienced with other cognitive enhancers. It's fantastic for those high-pressure moments where you need to stay sharp and collected.I also appreciate its versatility. Whether I'm trying to unwind after a long day, prepare for a presentation, or simply want to enhance my meditation practice, L-Theanine consistently delivers. It helps me transition smoothly into a peaceful night's sleep without any grogginess the next morning.If you're looking for a natural, effective, and gentle way to support your mental well-being, reduce stress, and improve focus, look no further. L-Theanine is a game-changer, and I wholeheartedly recommend it!

No taste, no fillers, no gimmicks—just reliable, fast-acting theanine.If your brain is stuck in high gear or your nervous system’s on a tightrope, this is the supplement you want in your daily rotation.Verdict:Clinically sound. Cost-effective. Consistently calming.

At my weekend security job patrol we have to cross over the roof on the 12th floor penthouse level that has a low parapet along the edge where we have to walk. It makes my fear of heights kick into high gear. I have been crossing the roof for three years now and everytime I get panicked. It sucks. So I took a double dose of this last weekend an hour before my patrol started both Saturday and Sunday and felt slightly less panicked. I also made sure not to ingest any caffeine before my patrols. I also have been taking it at night before bed with my usual ashwagandha, valerian and chamomile sleep regimen and it seems to help keep me asleep and wake up refreshed.

It hasn't helped with sleep whatsoever. BUT it does help to reduce inflammation in the body so I will use at least this bottle.

This L-Theanine has been a lifesaver for calming my system when I’m overstimulated. It helped noticeably lower my heart rate and blood pressure during anxious moments, and brought on a sense of calm and focus without any drowsiness. It’s now my go-to whenever I feel overwhelmed. The capsule is easy to take, and delivery was quick. A solid 5 stars from me — I’ll definitely be reordering.

So far so good. My brain is quiet at times, and I'm able to focus on meditation... Less of a brain fog

I have been taking these for awhile and will continue to keep them in my daily vitamins

It works. I noticed that I do focus better and I’m more alert after taking it.
