Energizing
I decided to try l-tyrosine to address my difficulties with focusing and working efficiently while coping with chronic sleep deprivation. I have been taking it for about a month, 1000mg before breakfast and 1000mg before lunch. It helps quite a bit, and improves my mood. I can really tell the difference if I skip a day. I would caution against taking this too late in the day as it can cause insomnia (I was up until 6am after taking 1000mg at 7 pm)

飲み始めて1ヶ月、毎日朝に服用。 飲み始める前は、以下の症状 ○ストレス常態下に置かれないとやる気にならない。やりきった後の燃え尽き感 ○特に休日や大きな仕事をやりきった後にに訪れる倦怠感、そして頭痛、吐き気 (自律神経が乱れる感じ) ○周囲の雑音が気になる時がある。 (思考が纏まらない。) 飲み始めて以降 ○集中力の持続、やる気の持続 →残業、徹夜、休日出勤が苦にならない。 ○倦怠感、頭痛の消失 →頭痛薬からの解放 ○周囲を意識しなくなる。 →神経がすぶとくなった感覚 変化が顕著過ぎて、気持ち悪いぐらいです。まだ、1ヶ月ですが、これが継続すれば、人生の質が劇的に上がると考えています。 以下、追記 集中状態が継続するため、不思議な疲労感があります。 以前は、集中→精神摩耗、思考ストップでしたが、集中が継続するため、疲労感がどっとくる(しかしメンタルは無事) という感じです。 以下、半年経過 継続して飲み続けた為、上記集中力継続がある程度常態化 この間、ストックが枯渇した期間が半月ほど生起しました。 「チロシンがない」という意識は無いつもりでしたが、焦燥感、不安感、倦怠感、思考発散。。本来の自分?に逆戻り。ふと「そういえばチロシンが切れている」と気がつき、急遽、使用している後輩に分けてもらうと。。。 効果抜群。改めて怖いですね。

同ブランドのフェニルアラニンも飲んでるが、フェニルアラニンよりはチロシンのほうが効果を感じる。ていうかフェニルアラニン飲んでも何も無い。チロシンは飲むとちょっと元気になるような気がする。

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!
