My Honest Review
I never write reviews, but felt for this one I would. I did my research beforehand as I had read it was a good one to take for mental clarity, focus, sleeplessness and overall happiness. I have been taking it for a month now and here is my own results and observations since I started. My mental clarity and focus was improved. I have never been diagnosed with ADHD, however I have always been one to get easily distracted and never finish a project unless I’m under fire. This hasn’t been a problem per se, but since having kids it’s been harder. I get interested in something and start it, but then something else comes up and I move on and never go back. The same goes for work. I work on a project and get asked a question or for help with something and then I lose focus and motivation so it’s hard to get going again. This helped. It’s not a miracle drug so don’t expect that, but it’s makes the transition easier and getting back on track easier. It’s what I needed. My sleep wasn’t necessarily bad, but it also improved. I’ve been wearing a FitBit to bed for years and my awake time was consistently more than 10% of my total sleep time (time from when I went to bed to time I woke up). Most of this 10% was time I was technically sleeping, but my body registered “awake” even if I didn’t remember it. Since taking the l-tyrosine it’s been consistently below 10%. Again, it’s not a miracle drug, but any improvement I attribute to the one change I made to myself and that was taking this. Also, my sleep score went from a below 90 average to above 90. I feel good when I wake up now and don’t feel the need for a nap mid-day so that’s a plus! The overall happiness was something that I read, but wasn’t something I struggled with or cared about, but I did see some improvement there too. Could it be the better sleep or the happiness from staying focused more? Finishing more projects than usual? Possibly, but either way I’ll take it! What I didn’t anticipate was the curbing of any sugar cravings and this was wonderful! I always want something sweet. I crave the sweetness, but since taking this supplement I don’t crave the sugar. No chocolate, no cookies, no ice cream. I’m not saying I didn’t indulge once in awhile, but I didn’t crave it anymore. With that being said, I did manage to lose 5 lbs this month! With this being said I will say that I read taking the L-tyrosine with a B6 supplement helps it be more effective and so I did take my Vitamin B Complex, L-tyrosine and my Vitamin D all at the same time. The B Complex and Vitamin D I had already been taking and I only added the L-tyrosine in the last month. I’m not sure if it would work differently without the B Complex or not, but I figured I’d mention it just in case. Hope my feedback helps anyone else considering taking this!

ADHD Necessity
If you’re one of many struggling with the ineffective and unreliable ADHD medication, give this a try. Taken 30 minutes before food/coffee in the morning, I begin to feel an uplifted mood and increase of energy/ focus that seems to boost the lacking prescriptions. The pill is moderate size, I always trust this brand to be high quality and high value for the money. All of my supplements are NOW (which are many as I’m getting old). Until medications return to their former therapeutic value, this will be a daily supplement.

Supports my antidepressant
I take this at night in conjunction with my very low dose of antidepressant. I take an SNRI. This reduces brains zap if I happen to miss my antidepressant and improves the effectiveness of my medication without the need to raise my dose. I recommended to everyone.

ITs ok
I’ve been using NOW Supplements L-Tyrosine 500 mg for a while now, and while I do think it has its benefits, it didn’t completely blow me away — which is why I’m landing at four stars instead of five. Let’s start with the positives, because there are definitely some. I noticed a subtle improvement in mental alertness and focus, especially on days when I felt mentally sluggish or overwhelmed. It’s not a stimulant feeling — no jitters, no racing heart, no wired energy — just a smoother, calmer sense of mental clarity. I felt a bit more “online,” if that makes sense. I like that this supports neurotransmitter function rather than acting like a quick fix. It feels more supportive than forceful, which I personally prefer. On busy or mentally demanding days, it seemed to help me stay more focused and less foggy, especially when taken consistently. The capsules are easy to swallow, and the dosage feels reasonable at 500 mg. I didn’t experience any negative side effects, stomach issues, or weird reactions, which is always a big plus when trying supplements that affect mental function. NOW Supplements is also a brand I generally trust, and the quality feels solid. The bottle is straightforward, clearly labeled, and gives you a good supply with 120 capsules. That makes it a decent value, especially if you’re planning to take it regularly. Now for the reason it’s not a full five stars: the effects were subtle. Helpful, yes — dramatic, no. I didn’t experience a huge boost in motivation or a noticeable surge in energy. It was more of a gentle support than a noticeable change. If you’re expecting a strong, obvious mental kick, this probably isn’t it. That said, I think this works best when paired with good sleep, nutrition, and realistic expectations. It’s not a magic pill — it’s more of a quiet helper in the background. Some people may notice more benefits than others, depending on their baseline and needs. Bottom line: four stars because this supplement is well made, easy to take, and offers subtle mental support, but it didn’t feel strong enough for me to call it a game changer. If you’re looking for gentle cognitive support without stimulants, this is worth trying — just go in knowing the effects are more understated than dramatic.

Warning: wonderful changes for me, but it's not for everyone.
I take this brand of l-tyrosine daily, every morning, and it has helped me noticeably with my energy and anxiety levels. I have a fructose malabsorption problem that interferes with my uptake of certain neurotransmitter precursors, and supplementing with this on an empty stomach seems to help me focus and feel a little more motivated. I do take a much lower dose than recommended - I split the contents of each capsule up into four capsules, effectively taking 1/4 of a capsule every day, about 125mg, but I am so sensitive to medications/supplements that I typically take 1/4 to 1/3 the regular-strength dose for really everything (including things like ibuprofen and claritin). Taking a larger dose of tyrosine has a noticeable effect on my libido and also makes me feel extremely calm (and a little uncoordinated). As long as I wait an hour to eat after taking a small dose, I have mild, but positive effects. (Eating right away means I have no noticeable effects; I assume this is because other amino acids in the food I eat have higher priority and out-compete tyrosine.) If I stop taking it for a few days, I don't notice any awful withdrawal symptoms. This seems to be a much more predictable and less dependency-inducing supplement than I have heard L-DOPA to be, although I have not tried L-DOPA myself. On the flip side... I recommended this to my husband, who struggles with lack of focus and motivation (he's in a really thought-intensive occupation, so this is particularly disruptive). He took a full capsule every morning for a week or so. The first few days, he felt like he had a little more energy and motivation, and that he was able to lift a bit more on his workouts; he said it was about the same as a cup of coffee, except without the jitteriness, and the effect was strongest about 2-3 hours after taking it on an empty stomach and lasted several hours. However, after about three days, his mood shifted so drastically that he was really impossible to live with. He became extremely angry, on-edge, defensive, aggressive, critical, negative, and prone to violent outbursts. It was a complete and terrifying transformation; he became a brute, where normally he is a patient, gentle, kind man. It took a few days before I realized what was causing the change, and he stopped taking it. The next day, he returned to being gentle and loving, with no noticeable traces of the monster he'd been. Perhaps he needed a smaller dosage, although we weren't willing to try, and I'm not sure this would have helped. Really, I think his physiology wasn't meshing with the tyrosine supplementation, but I don't know how we would have predicted that before we tried it. Biochemistry is a complicated business. So, do I recommend it? I recommend that if you have difficulty focusing, getting motivated, and dealing with crippling anxiety, you try it, in low doses, and watch your moods carefully. Be prepared for the possibility that you become a raging monster, and if you do, stop taking this stuff ASAP. However, there's a chance that you'll have wonderfully positive effects from it, too, like I did. I say try it and see, just be mindful of what's happening. TL;DR: It made me calmer and more focused in small doses, but it turned my husband into a raging demon with regular-strength doses. Try it in small doses and watch the effects carefully. It may or may not be worth it. It was for me, definitely not for him.

L-Tyrosine really has helped......
This is my first review on Amazon EVER and I have been on here a long time. I have just purchased my fourth bottle and I will continue to order this product. For me the changes were within 30 minutes. I am not sure what condition this truly solves but I suspect anyone low on endorphins would benefit greatly. I have the unfortunately issue of having kidney stones on a regular basis, probably 1-2 a week. Doctors frown upon giving out pain meds so I generally deal with the kidney stones as best I could on my own. What I discovered is that my mood was horrible because I was constantly exhausted from dealing with the stones on a daily basis. In desperation I picked up the "Mood Cure" through audible. I bought all the stuff they recommended to try; GABA, L-Trytophan, DLPA, L-Tyrosine, 5-HTP the list goes on. The L-Tryrophan and 5-HTP basically did the same thing, they both made me tired so I took them in the evening. GABA, same effect, tired but I did notice it has a calming effect. Long story short, my serotonin levels were never the problem with my mood, even before the kidney stones. I believe I have naturally low endorphin levels and the kidney stones definitely degraded it even further. After taking L-Tyrosine and/or DLPA (they both worked but I think I like L-Tyrosine better), my mood improved greatly. My wife has noticed and I have noticed. I am simply a happier person even though I am going though all this. I am NOT saying this relieves pain but it does help ME with the exhaustion and mood that usually accompanies it. I take 1500mg (=3 capsules) first thing in the morning. By the time my shower is half way done I feel the effects. I then take 2000mg 6-7hrs later. I would not take it past 6pm as it will keep you up. I am sorry to hear this product does not work for everyone but I must say it only helps with a certain condition. I think if you have tried anti-depression or anti-anxiety medication and it made you more irritable then serotonin isn't your problem and maybe you should look at endorphin levels instead. I hope this help someone.

眠りの質が深くなったような気がします
■購入したきっかけや、用途 お仕事などで毎日がとても忙しくて、様々なことにおいてなかなか集中力が続かないことが悩みでした。どうしてもやる気が出なくて困っていたときに、インターネットでこのサプリメントを見つけました。アミノ酸の一種であるチロシンが含まれていて、やる気や集中力をサポートしてくれるという評判を聞き、自分の今の状況に合っていると思って購入を決めました。 ■良かった点 まず良かったと感じるのは、作業をするために机に座るまでの心のハードルが少し低くなったことです。今までは作業を始めようと思ってもダラダラしてしまいがちでしたが、これを飲むと目の前の課題に取り組める時間がなんとなく増えた気がします。 カプセルのサイズは海外のものなので少し大きめですが、表面がツルツルしているので、多めの水と一緒に飲めば喉に引っかかることもなくスムーズに飲み込むことができます。また、一瓶に120カプセルも入っているので、毎日使っても数ヶ月は持つのがおサイフにも優しくて助かっています。 変な味やニオイもしないので、サプリメントに慣れていない私でも抵抗なく続けることができています。 ■気になった点 気になった点は、一粒の大きさが日本のサプリメントに比べると大きいことです。慣れるまでは注意が必要かもしれません。
