I 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
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.
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...

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。
