Review: 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.
Review: Easy to Administer and Good Flavor - I’ve taken this supplement before but wanted something I could dose to fit my needs and use quickly. I am postpartum and needed this alongside several other supplements. This brand always impresses me with quality. The flavor is good, easy to administer and is effective. I use it in the morning and before bed. It is effective in keeping my mood stable over the course of day and helps me sleep at night as well. I do feel more focused when I take it as well, however I am taking a lot of vitamins so hard to say this one specific to that. I think it’s a good value too, it’s a decent supply for the cost. I recommend trying this brand!

### ⭐⭐⭐⭐⭐ ⭐️⭐️⭐️⭐️⭐️ Great Daily Supplement for Focus and Balance
*by C***Y on September 2, 2025*

I’ve been using MaryRuth’s L-Theanine Liquid Drops as part of my daily routine, and I’m really impressed with the results. The lemon-lime flavor is light and refreshing, and I appreciate that it’s sugar-free and alcohol-free, which makes it feel clean and easy to take. I usually add it to my morning coffee, and the combination has been a game changer. Instead of experiencing the usual mid-day crash, I feel more balanced, focused, and attentive throughout the day. It seems to smooth out the caffeine buzz and helps me stay productive without the jitters. MaryRuth’s is a company I trust, and this product really reflects their commitment to quality and effectiveness. If you’re looking for a natural way to support focus, reduce stress, and avoid those caffeine crashes, I’d highly recommend giving this supplement a try.
