L-Tirosina, 500 mg, 120 Capsulas
A tirosina é um aminoácido aromático não essencial, ou seja, que é produzido pelo organismo a partir de outro aminoácido, a fenilalanina. Além disso, também pode ser obtido a partir do consumo de alguns alimentos, como queijos, peixes, abacate e nozes, por exemplo, e na forma de suplemento nutricional, como L-tirosina.
Esse aminoácido é precursor de neurotransmissores como a dopamina, estando associada a efeitos antidepressivos, e também está presente no processo de síntese de melanina, que é uma substância que dá cor à pele, olhos e cabelo.
Além disso, a tirosina contribui para o funcionamento da glândula tireoide pois participa da produção dos hormônios tiroxina (T4) e triiodotironina (T3), que são responsáveis por regular o metabolismo.

Descrição
Para que serve
A tirosina pode servir para diversas situações, garantindo benefícios para a saúde, sendo os principais:
- Melhora a depressão leve e moderada e o humor;
- Melhora da memória em situações de estresse, melhorando a capacidade de realizar tarefas sob pressão. No entanto, alguns estudos sugerem que esse efeito não acontece em pessoas mais velhas;
- Aumento da quantidade de células brancas e vermelhas do sangue;
- Ajuda no tratamento de algumas doenças, como o Parkinson;
- Melhora o rendimento na atividade física;
- Diminui a intensidade da resposta do organismo frente a uma doença ou a uma situação de estresse, convertendo-se a um aminoácido essencial, já que nesses casos suas necessidades são aumentadas.
Dessa forma, a suplementação de tirosina poderia ajudar as pessoas que possuem fenilcetonúria, que é uma doença em que não é possível sintetizar a fenilalanina. Com isso, não é possível que exista formação de tirosina, já que esse aminoácido é formado a partir da fenilalanina, resultando na deficiência de tirosina no organismo. No entanto, os estudos que relacionam o uso de suplemento de tirosina em pessoas com fenilcetonúria ainda não são conclusivos.

Como usar o suplemento de tirosina
Existem dois tipos de suplementos, uns com o aminoácido tirosina livre e outros que possuem N-acetil L-tirosina, popularmente conhecido como NALT. A diferença é que o NALT é mais solúvel em água, podendo ser metabolizado no organismo mais lentamente, enquanto que para receber o mesmo efeito é preciso que a tirosina livre seja consumida em doses mais altas.
Para melhorar o desempenho mental diante de uma situação de estresse ou devido a períodos de privação do sono, por exemplo, a recomendação é de 100 a 200 mg/kg por dia. Apesar dos estudos não serem conclusivos quanto à ingestão desse aminoácido antes da realização de atividades físicas para melhorar o desempenho, recomenda-se o consumo entre 500 e 2000 mg 1 hora antes da atividade.
De qualquer forma, o ideal é consultar um médico ou nutricionista antes de fazer o uso do suplemento de tirosina.
Contraindicações da suplementação
O uso do suplemento é contraindicado durante a gravidez e o período de amamentação, uma vez que não há muitas informações a respeito. Também deve ser evitado por pessoas com hipertireoidismo ou com doença de Graves.
Além disso, a tirosina pode interagir com medicamentos como a Levodopa, com medicamentos para tratar problemas da tireoide e com antidepressivos e inibidores da monoamina oxidase, já que pode causar aumento da pressão arterial.
As pessoas com problemas hepáticos ou renais devem usar o suplemento de tirosina apenas sob orientação médica.

Compare to adderall
7 months agoI bought this supplement mainly as a nootropic to help me raise dopamine levels in the brain, It did help me with a slight motivation and mood. I took 2 a day in the morning . It has also other benefits .Dopamine is involved with libido, memory, focus, goal-oriented concentration, a mood elevator and anti-depressant. Norepinephrine helps with alertness, working memory, focus, and executive function. L-Tyrosine supports healthy glandular function and stress response because it helps with the synthesis of thyroid hormone and epinephrine (adrenalin). L-Tyrosine also plays a role in controlling organs responsible for creating and regulating hormones in your body. Including your adrenal glands, pituitary gland and thyroid. It can sharpen memory, is anti-anxiety, boosts mood, and protects brain nerve cells from neurotoxins. . L-Tyrosine suggested dosage for cognitive benefit is 500 mg – 2 grams per day. You may find your body responds to smaller doses. Or even more if you’re stacking it with stimulants like ADHD meds. Listen to your body and see how you react. At higher doses there are reports of stomach issues and migraines. Migraine problems usually happen to those who already suffer from migraines. This may be an indication that your neurotransmitter levels are already optimal, and you don’t need to supplement with L-Tyrosine. L-Tyrosine can increase your thyroid hormones. So if you’re hyperthyroid you shouldn’t use L-Tyrosine. And if you’re taking MAO inhibitors (MAOI’s) like selegiline, Azilect, Marplan or Nardil you should not use L-Tyrosine. MAOI’s work in your brain by blocking the enzyme monoamine oxidase. This enzyme normally blocks excess dopamine. But when you block the enzyme, more dopamine is released. So using L-Tyrosine in combination with MAOI’s could raise dopamine levels to high. Resulting in a rapid rise in blood pressure (hypertensive crisis). Causing severe headache, nausea and sweating, severe anxiety, rapid heartbeat, chest pain, vision changes, shortness of breath and confusion. Try and see if L-Tyrosine works for you, If not you can try NALT or even L-Dopa to increase dopamine in your brain. Slowly try each product and see which works perfectly for you

ムズムズ脚の良いとのこと。チロシンは、ドーパミンの原料になるらしい。
「飲み合わせや飲む人が特定の病気だと、飲めない」という注意書きが入ってました。副作用や弊害がでてからだとあれですからね。親切でありがたいです。効果が有るぶん、多少注意が必要なのかな。ムズムズ脚症候群の改善に、薬以外の選択肢として購入。チロシンはドーパミンの原料になるそうで。とりあえずムクナ豆（こちらはドパミンの原料になるLドパが入ってます）から飲み始めようと思います。チロシンは、もう少し調べて詳しい人に飲み合わせなど聞いてから再開しようと思います。あと以前買ったコリンは、パニック障害とかに良いらしいですがムズムズ脚はコリンの量が多くて、ドパミンの量が少ないというバランスだと出やすいそうなので、とりあえず飲むのをやめてます。

Surely notice some changes
Noticed changes in mood after taking these for few days. Start with 1 cap per day and increase as per how you feel. I have been taking 2/ day and have noticed positive mood throughout the day.You have to look into a healthy diet along with this as this is a supplement. However many brands offer the same at lower price, will try buying few well known companies to see if they work.

Good Price For Quantity
My Doctor recommended that I take Tyrosine in order to help balance my brains neurotransmitters like Dopamine and Serotonin.I got addicted to my Fentanyl patches after taking them from a pain doctor for over 5 years. Long story…but needless to say what opioids do to your brain is screw up the balance of neurotransmitters. When you stop taking an opioid like Fentanyl, your brain doesnt jist start producing the right amount of dopamine and serotonin. Instead, you are depleted of these imlortant good chemicals for a long time after stopping any opiood. It depends on how long you were on opioods and at what strength or dose as to how long it will take your brain to heal and balance out these neurotransmitters. In my case, i was looking at a long time. I was on super higher dose of fentanyl 400 mcg patches ingesting them. For about 6 years before, during and after 5 reconsteuction surgeries.I was looking at at least a year before my brain totally balanced out after stopping opilids completely. That was NOT fun at all. Deathly experience i would say.So, after getting educated by my doctor…he said that I could speed up the balancong process by taking precursors…Tyrosine like this one is a perfect example.I found these ones that were priced good for the amount. ive been taking them and they seem to helo fight off depression and feelings of despair which is what you get when you are depleted of the brains dopamine and serotonin.Be sure to take these every single day because its going to take a few weeks before they take affect. It takes a while for the tyrosine to get flowing throughout your blood and body. I hope this helps depending on what reason you have for taking tyrosine. Let me know if this review was helpful or not below.

amazed by the results
I wanted to wait until I had used this awhile before I gave a review to see how the effects last. I was very skeptical when getting this product because I was skeptical that something over the counter could make as big a difference as some people claimed. I researched a lot about its effects and how it works and since it made sense, I thought I would give it a try, but honestly didn’t expect much. For years I have suffered from a “foggy head”. It doesn’t seem to matter if I sleep 8 hours a night, or 4, or 10, I always wake up tired and with brain fog that persists. Along with that, I’ve also dealt with depression over the years and some major irritability. As I tend to be pretty sensitive to most medications, I wanted to start out with a smaller dose to see how it would affect me. I opened the capsule and dumped half the contents out, then closed it again and took it with a glass of water. I had eaten about an hour before. I noticed some mild effects and that at work I was breezing through things that usually took me a lot longer to do. There was no stomach upset at all. After reading up on it, I saw that its most effective if taken on an empty stomach, but talking anything on an empty stomach makes me nervous as I’ve had so many meds make me incredibly nauseous if I didn’t eat. The next morning I again dumped about half of it out and took it on an empty stomach and noticed a big difference. Within maybe half an hour the brain fog cleared and I felt truly alert for the first time in years with no jitters or stomach upset at all. The effects lasted until the afternoon and I took another half which got me through the rest of a long day at work. That night I slept great, and felt pretty good when I woke up. Since then I take a full one immediately when I wake up and before I eat anything. I’ve noticed if I eat anything high in protein before I take it the effects are greatly lessened. This is because l-tyrosine and protein use the same transporter to the brain, so it competes with the protein if you have them both at the same time. Taking a full one every morning keeps me alert and focused all day with no nervous energy, no anxiety, no jitters and no crash. I’ve been on this same dose for several weeks and it still works just as well. This is now a permanent part of my morning when waking up. I was amazed at the huge difference it made in my ability to concentrate, my focus, energy and my mood. It keeps me feeling pretty uplifted and happy. My life seems much better since I started taking this. This is the only brand I’ve used, so I have nothing to compare it to, but I will stick with this one. If it ain’t broke…

Science-Minded Multiple Chemical Sensitivities Sufferer –
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.

Works Really good for anxiety, depression
As someone who is self-employed, without insurance, and has been diagnosed several times with clinical depression I’ve been motivated to do a lot of research on natural remedies to coping with this “illness” rather than go the RX route. I’ve taken probably 15 different “cures” or combination of such over the past 5 years and have found a combo that works for me. Not a cure, just something that makes the low times shorter and less intense. Which to some people, is a cure in itself.The first thing I found to be effective is L-Tyrosine (hence the review), Now Foods L-Tyrosine 500mg, 120-Capsules is an amino acid that your body can create on its own or get from food. It is a precursor to several neurotransmitters, including epinephrine or adrenaline, norepinephrine and dopamine. Two of these compounds, epinephrine and norepinephrine, are commonly called stress hormones because your body releases them as part of the mechanism that helps you deal with stress. As a result, increasing your levels of L-tyrosine may help you cope with situations that might trigger anxiety.I’ve tried a number of different supplements with and without L-tyrosine and have found the best results for me have come from taking this and TranquiliX; #1 Top Rated For Rapid Anxiety and Stress Relief ★ Pharmaceutical Grade Anti-Anxiety Formula for Relaxation and Stress Reduction With Mood Support & Patented AES® Delivery System for Maximum Absorption ★ Try it 100% Risk Free! . Its a cocktail of a few different anxiety ingredients and works pretty darn well when I combine it with the L-tyrosine. I still do have the ocassional “episode”, as my wife likes to call them. But adding these two supplements along with a healthy diet and exercise has made the world look much brighter through my eyes.

ADD, thyroid, adrenals…
I think they work and the price is right but why must Now Foods put rancid rice flour in all their supplements? If you’re just taking one supplement fine, but multiple supplements everyday. I love now foods for making affordable quality supplements that allow us to take control of our wellness. They’ve been around forever, offering wellness products before they became so main stream. I just wish they would upgrade formulas to exclude the rice flour or some how convince me that it’s at least gmo free and organic rice flour. Also, those taking supplements like tyrosine might find reading up on orthomolecular medicine very interesting and helpful. Sometimes we don’t reap the full benefits of a supplements when taking as directed on the bottle. For instance, vitamin c bottle will say 1 a day, but we are all different and those with weaker immune systems could benefit from much higher doses. Again, consult with a ND or Od or do your research. I read that those with low dopamine levels could take upward of 2000mgs a day. Again check with your doctor. I’ve experimented with 1500 mgs so far so good. Lastly, anyone suffering from hypothyroid, hashimotos, sleep disorders, depression, ADD, ADHD, fatigue, etc. please please please have your doctor check your cortisol levels. I was treated unsuccessfully for years for hashimotos, when the thyroid medicine wasn’t helping me get out of bed or feel focused and alert thru the day, my MD suggested antidepressants. Those didn’t help, I was still exhausted and in pain. Finally I asked to have my cortisol levels checked and sure enough they were very low (despite weight gain). Addressing adrenals will help regulate the thyroid, give you the energy you need to focus, balance out dopamine levels, and feel more wakeful. Tyrosine is good for nourishing the adrenals as well. Still it’s best to have cortisol levels tested. Cortisol and candida levels but that’s a whole other story. Those two simple tests could be life changing, and save thousands in future medical costs.

Can’t believe this works!
Let me just say this is kind of a miracle…for me at least. I’ve suffered from A.D.H.D., depression, slight substance abuse in the past and this helped me more than any pharmaceutical ever did! Wish I knew about it sooner. My friend who is in the air force actually mentioned it one day so I asked, glad I did! It’s natural, obviously if she’s in the air force lol, some people just lack it I suppose. It literally works right away, giving more energy, focus, mood support. Seriously there’s a reason “Dr.s” don’t tell us about it….we wouldn’t need them for that anyway and the pharmacy would loose money. Seriously if you have, or have had, any of the issues I do/did give it a try! Oh, make sure to take it in the morning. I only take 1, im 5’2″ 140lbs. I did have a little trouble falling asleep the 1st few nights but then adjusted.

A product I didn’t know I needed!
I recently started intermittent fasting. I fast for 18 hours, and eat for 6, and when watching youtube videos, a lot of the people who are professions with IFing recommended taking L Tyrosine to make things easier during your intermittent fasting window. They said it would help with stress, and also help you sleep at night; something I wasn’t getting a lot of because I was starving at the beginning. I thought it was a product that would eventually help over time, and wasn’t expecting it to have instant effects. Right off the bat, I felt less stressed, my anxiety seemed to be calmed, and I felt just… chill.. but not tired. After taking the pills for about 4 nights, I found that I wasn’t tossing and turning for hours at night, and fell asleep easily, and stayed asleep. It doesn’t MAKE you sleep, it just lets you sleep when you’re ready, and I really appreciate that. Now that I’ve been taking L Tyrosene for two months now, I recommend it to everyone, not just people who are intermittent fasting. It does so much for stress and calmness, and I feel everyone needs that now a days. Cannot say enough good things about this product.

If you get headaches/migraines, you may have methylation issues
So I got these pills 4 days ago and have only taken 1 a day. The first time, I almost immediately got a headache. Now I have suffered from migraines in the past, on and off, but I came here to search for reviews that mentioned headaches or migraines and found quite a few, and they were recommending avoiding this supplement. But I ordered this supplement because I really need help with my depression, so I wasn’t going to give up that easily.I noticed some reviewers mentioning MTHFR which is an issue for me. Looking it up, it turns out that people with MTHFR have issues metabolizing l-tyrosine because it requires folate (also copper and vitamin C). Since most of what we get (fortified foods and the average vitamin supplements) contains folic acid (which is not natural) and our bodies have a hard time using that where folate is needed (and some can’t use it at all), the l-tyrosine doesn’t get rapidly metabolized as it’s supposed to be and lingers. That is what I read causes the headaches/migraines.I have a methylated B complex. So as a test, I took one of those pills (and the daily dosage recommended is 2, but I’ve never taken that much) and the headache went away. I also have vitamin C (sodium ascorbate powder) and would have tried that next. I was actually kind of hoping to avoid taking another pill everyday. I’m a slacker in that regard.My husband has exactly the same methylation issues as I do and he got a migraine. The methylated B complex also worked for him. I didn’t tell him beforehand that it would. In fact, he assumed I still had the headache.So to those who are getting headaches/migraines from this product, you could have problems metabolizing the l-tyrosine because of methylation issues. If you have already done DNA testing and you’ve gotten a report from Promethease, check it for MTHFR. If you’ve done testing but don’t want to pay for Promethease, use codegen dot eu instead. If you already have vitamin C at home, give that a shot too. Maybe you’re already good on methylated B vitamins but you’re not getting enough vitamin C. And less likely is low copper, but I have heard of it. Best to get copper levels tested before you go supplementing with it though. Don’t mess around too much with metal levels.As for how well the product works, let me just say wow, the absorption rate is incredibly fast. I feel very mellow, and even though I can still get angry, I don’t feel like it consumes me like it used to. I can calm down quickly and easily without issues.My husband seems quite mellow now too. I haven’t asked him how he feels. I’ve just been observing him. He doesn’t seem to get agitated easily on this. If he does get angry, it stops almost as soon as it starts. I don’t think I’ve heard him swear at all in the last 4 days. He’s much more pleasant to be around which helps my mood as well, but I can tell you I don’t usually feel this mellow. I even found myself smiling and singing and dancing randomly.I seem to have more trouble getting to sleep at night even though I take it as soon as I wake up and nowhere near bedtime, but my husband has been going to sleep earlier and actually talking about feeling tired. So there it seems to be having opposite effects on us. I don’t mind though because my mood has not been this good in years, and it’s amazing not seeing my husband stay up all night like he used to. I’m going to use melatonin at night long enough to see if it can help me get back on track. At least once I get to sleep, I do sleep well, even when I don’t sleep enough. Usually, if I woke up after 6 hours of sleep, I felt like someone rubbed sand in my eyes and that would last until I did get enough sleep.

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!

WORKED FOR ONE OUT OF TWO ISSUES IT WAS INTENDED FOR!
I bought this product with such a hope for my teenager son who suffered ADD! Because of his ADD and being struggling in school he have an extremely low self confidence which has resulted in episodes of depression!!!! He has talked about self harm and showed interest in drugs!!!! As a parent I felt broken and ordered this product!So when I got this there were couple things I was hoping for you, first that this will help him focus and secondly he will get in better mood! First of all let me start by saying its almost 3 weeks he is been on this product……it has not caused any major side effect other than a minor headache one day,I did started very slow and gave him half the capsule by taking it apart in the middle and spilling half the powder away, Now he takes one everyday other than on Saturdays we take a day off.As for performance he still have lots of missing work from his school, he still forgets to turn the light off in his room, still is fidgety HOWEVER along with all this I seen a great improvement in his mood!Before he had lost interest in life, Now he is excited for Christmas agaiN, I seen him dancing to songs! He is talking to me again, he was quieter before!!!!! We had to take his phone away as he was getting under influence of some people who were a bad influence on him……. that and this product I think both played a role in his well being!I honestly can’t believe this change and want to embrace it all because he has always being this sweet little boy and I have started to see that glimpse again……I am so forever thankful to each and everyone of you who wrote good reviews for this product! I cant tell you how many times I read those comments and they provided me with such a relief that there is hope for us!So as for recommending this product I would say Please try specially if you or someone you know is going through emotional stress/depression, My best wishes are with you and Don’t lose hope ! I hope this positivity is here to stay with my son and overtime he will be capable to do the things his peers can do………….UPDATE- After abt 3-4 weeks of use, my son now started to get nose bleeds, but he is still in good mood so far, THANKS to GOD! So you might don’t need it for very long time, please monitor as you take it closely, Listen to your body!! Sending positive vibes to all……

Suitable for pets
I took care of my daughter’s aging dog for a few weeks during a move. He was on this supplement to help his mental function via the neutral pathways of the brain. He remained every bit as alert as he’d ever been all the way to the end. His nails and coat, also affected by this supplement, remained healthy as well.
