Love this stuff
I bought this because it helps balance my ADHD medication. We’ve been using it for 6 months(2nd time Purchasing) What I like most is it’s not another pill to take, easy flavor to put into any drink. Overall, I’d recommend this for anyone who wants a calming stress reducer that’s not another pill

Helps anxiety & sleep
I have anxiety which interferes with my ability to sleep. I have started taking this 30 minutes before bed time and it has helped tremendously to relax and calm my brain. For any other nerds like me that like to know how about the supplement and how it works, here is info from Psychology Today about L-theanine: L-theanine promotes relaxation and facilitates sleep by contributing to a number of changes in the brain: Boosts levels of GABA and other calming brain chemicals. L-theanine elevates levels of GABA, as well as serotonin and dopamine. These chemicals are known as neurotransmitters, and they work in the brain to regulate emotions, mood, concentration, alertness, and sleep, as well as appetite, energy, and other cognitive skills. Increasing levels of these calming brain chemicals promotes relaxation and can help with sleep. Lowers levels of “excitatory” brain chemicals. At the same time it is increasing chemicals that promote feelings of calm, L-theanine also reduces levels of chemicals in the brain that are linked to stress and anxiety. This may also be a way that L-theanine can protect brain cells against stress and age-related damage. Enhances alpha brain waves. Alpha brain waves are associated with a state of “wakeful relaxation.” That’s the state of mind you experience when meditating, being creative, or letting your mind wander in daydreaming. Alpha waves are also present during REM sleep. L-theanine appears to trigger the release of alpha-waves, which enhances relaxation, focus, and creativity. One of the appealing aspects of L-theanine is that it works to relax without sedating. That can make L-theanine a good choice for people who are looking to enhance their “wakeful relaxation,” without worrying about becoming sleepy and fatigued during the day.

Quick relief from anxiety
I'm ordering these drops for the ninth time. I have tried many versions of L-Theanine, but keep coming back to the MAX. It's easy to take, and more importantly, provides almost immediate results without any downsides or side effects. I would use the MAX even if it tasted nasty because it is so effective. Fortunately, the flavor is pleasant, thanks to the lemon extract that appears on the short list of added ingredients. No sugar, salt, gluten, soy, or other potentially problematic substances. The formula does include stevia, which sometimes gives me headaches, but apparently there's not enough in the MAX to trigger those. I realize not everything works for everyone, but this has been a lifesaver for reducing my anxiety, almost as potent as prescription benzodiazepine

Great Product - great seller
I actually tried once to buy these vitamins direct from the manufacturer and its really just better to go on Amazon. It's easier and the vitamins get there in a couple of days. At this point I have a whole shelf of their products (and all my books have the bookmarks that come in the box!). My only 2 complaints are these: 1) Many of their sublingual vitamins have stevia in them. It's a migraine trigger for me but you only take a few drops and as long as I stagger them during the day I'm fine. 2) Some of the droppers leak. It's been hit or miss on this. about one in four drips when you use it so do it over the sink so you don't stain your shirt when you open a new bottle. Aside from that these are great vitamins and I can recommend the ones I've been using: D3+ K2, B12, Theanine, and Biotin.

Delicious
Tastes surprisingly good... I was afraid I would need to dilute it in water a lot but it's actually delicious straight out of the dropper. It suggests 2 droppers for the full dose but I've only been taking 1/4 of one dropper a couple times a day and it seems to be working pretty well. Feels like a tiny bit of caffeine but without the jitters or crash. This supposedly helps some people sleep. I felt it was keeping me up if I took it too late in the day. Good pick-me-up in the morning. I love that I can easily choose the dosage. When I took a pill form of theanine it made me feel "crazy" (i think the dose was too high and may have made me feel strange due to my medications).

Relax at bedtime to sleep better
This was recommended to me as a relaxing agent to help me sleep. I put it in my glass of 100% cherry juice about an hour before bed andI have been sleeping better since. It has a slightly sweet flavor which is great in my cherry juice. I would recommend it.

Lemonade taste — flexible dosages
I’m enjoying this product, as I wanted an easy way to take a lower dose before bedtime (about 100mg). It’s true that the dosing is imprecise because the dropper itself isn’t marked, but that’s not critical for me. The taste is like lemonade (made with stevia) and I really like it. It seems like a quality product.

Loved before, now not so much...
Update: I contacted the company and informed them of this change, they say they didn't change the formulation at all, and sent me a new bottle. The new bottle tastes just like the original ones, still not sure why the one bottle tasted bad... I would love to give more stars, and up until yesterday I would have given 5. I have been ordering this product for almost a year now. It has been great, product tastes great, and it really does help with my anxiety without having to be medicated! But, the most recent bottle I received has a very strong smell and taste, and not in a good way, it almost seems as if it has gone bad, not really sure how to describe it, other than, its is definitely not the same product I have been taking. The new bottle label looks slightly different, words the same, but the fonts have changed. It is not expired. I am wondering if I just got a bad bottle or if the formulation has changed. I hope it is just a one time thing because I really loved this, but I cannot deal with the taste of the current bottle! I may try to order another to see.

Dropper does work!
Firstly let me set the record straight...the dropper does work... If you are trying to fill the entire dropper up you will be taking too much! It fills it for the correct dosage. If unsure get a syringe like the ones you get in children medicine and measure 2mls... I repeat do not try and fill the whole dropper you will be taking too much! This stuff is amazing and lasts forever...I've looked into it and you can take more than the dose it says on here so I take two droppers morning and night and it's lowered my heart rate and my stress readings and my sleep is deeper and I look forward to more great affects as I keep taking it . I highly recommend it

Buy buy buy
I’m 48, and when it comes to competency-based interviews, my nerves tend to affect my performance. I've never landed a job I really wanted because of it. I had an internal interview at my current company and, due to nerves and other factors, I was unsuccessful. This week, I had another interview, and with how important this job was to me, I knew I needed to try something to help manage my anxiety. After doing some research, I found this product and decided to give it a go. Now, if you're looking for something that will completely eliminate nerves, this isn’t it. However, it made a noticeable difference. While I still felt nervous, I didn’t get caught up in the usual cycle of overthinking and stressing. I wasn’t completely free from nerves, but I felt much more present and less overwhelmed. The boost in confidence might not have come instantly, but I definitely felt calmer and more in control. It tastes like lemon, and while I did experience a slight bit of nausea for the first 10 minutes, that quickly passed. By the end, I realized I had made it through the interview with less stress than usual. I highly recommend this product – it won’t eliminate nerves, but it will help you manage them so you can perform more smoothly.

Works Better Than Expected
Was originally introduced to L-Theanine through Guru energy drinks. I previously enjoyed other blends of Guru, with different caffeine sources, but particularly found myself to the theanine one they make. I noticed it really satisfied my craving for a focus-assisting beverage without making me feel as uppity as from coffee. Once I found this stuff, I tried it and immediately liked it. The flavour is mild and natural, citrus. There are no weird or unnecessary ingredients in it. I mix it with water and electrolytes. It feels exactly like the theanine from those gurus, except for 1/10th the cost. I have a heavy astigmatism and even with correction my vision is only 20/40. There is a noticeable increase in visual acuity if I have a 100mg+ serving. The only other substance I've had make a noticeable difference to my vision is psilocybin microdoses. I don't know how it works, but it's very pleasant. Additionally, it does provide a nice calming effect while giving me increased focus. There seems to be no drawback after a few weeks of use. I enjoy it in the evening as well and have been noticing myself getting deeper sleeps. I no longer crave any coffee after one in the morning, whereas I used to want several per day.

Helpful supplement
This helps calm my anxiety. And when I’m unable to sleep it helps to relax me and I’m able to fall asleep. I wish it was slightly cheaper but it’s a great product and it works for me. If you do have anxiety please do discuss with your general practitioner. I hate that this product is regularly out of stock so I have to buy at least 2 at a time.
