Very Effective
I bought this before going on a cruise for the first time, because I was really nervous and wanted something to help me relax. I have travel anxiety, and it was extra ramped up thinking about being on a ship. I took this the days leading to the trip but also the day of. I took it about 15-20 mins before actually boarding, and it helped so much. I could feel the relaxation hitting me. The taste is good, and I feel comfortable knowing it’s a high quality, safe product without weird ingredients. Very effective if you’re looking for a way to wind down before bed or to address everyday life stressors.

Tremendous help with focus and attention
These drops were recommended to me to help with my mood and focus throughout the day. It’s really been effective with both my mood and attention. I don’t really smell an odor and it doesn’t have much of a taste. I put a few drops in my coffee each work day and feel so much calmer and focused at work. I haven’t noticed any side effects and it’s definitely easy to swallow since there is no weird flavor. Note: it has no effect on my pain levels.

Currently in my 5th bottle Works well, tastes great.
I’m on my fifth bottle. I use it every night about 30 before bed and sleep well. I also take a magnesium supplement pill but adding this this has been a game changer. I also use it when I’m having a particularly stressful work day. If you are worried about taste, don’t. It’s good.

Tasty and Helps Me Feel Calm Before Bed
I first heard about this from a Korean influencer who recommended L theanine for focus and feeling calmer, so I decided to try it. I’ve been really happy with it so far. The liquid drops are easy to take, and I like that I do not have to swallow another pill. The taste is mild and not hard to use regularly. For me, it helps me feel more relaxed and settled, especially at night. I also noticed that I fall asleep more easily when I take it before bed, without feeling groggy the next morning. Everyone’s experience may be different, but this has been a really nice addition to my nighttime routine, and I would definitely repurchase.

Wake up so refreshed and no more anxiety from caffeine
I love the Mary Ruth’s brand of L-theanine, I have tried other brands, but this is the only one that consistently makes me calm and more importantly, as someone who suffers from insomnia, upper airway resistance syndrome, and fibromyalgia, which all impair my sleep quality, it improves my sleep quality dramatically when taken before bed. I take it under the tongue for faster absorption. Then I wake up feeling significantly refreshed, which has not happened with any other brands I’ve tried. I love that it’s natural and so easy to take, not another pill to have to swallow. It’s pleasant tasting, pretty sweet but has no sugar, just glycerin, so that’s fine. I like the synergy it has with my sleep meds of not making me more drowsy or sedated. It does not make me sleepy, not even like melatonin, but it simply allows me to feel much more refreshed with the same number of hours of sleep when I wake up. I also am one that tends to get super anxious and jittery from caffeine sometimes. When I’m starting to feel that panicky feeling after too much coffee or energy drinks, a couple dropperfulls of this stuff, and the anxiety is completely gone in thirty minutes. This is high quality, high caliber L-theanine, and I keep returning to this brand because of it. I’d highly recommend.

L Theanine for Anxiety
Love the product. It really does help with my anxiety jitters. It is tasteless and odorless. I add it in my chamomile tea in the mornings because that’s when I wake up jittery. It really calms me down. Now, it may not be ideal to drink it in the morning if you work or need to be awake because it relaxes you. Since I really need it I drink it anyways. Drank it at night once (100ml in am and 100ml in pm), but I feel like I woke up more anxious than usual. I’ve been trying to pay attention to my body reactions. It’s been working well for me but I still have good and bad days, more good than bad :)Unfortunately, The packaging was messed up though. The item was outside of the box and the box was smashed.

Works great
Love this for my adhd 9 year old. It regulates him with out making him groggy. Tastes like an unconcentrated sprite. My son doesn’t like the taste but doesn’t mind it. Recommend giving a.m dosage because we out son has trouble sleeping if taken too close to bedtime.
