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 Iâm under fire. This hasnât been a problem per se, but since having kids itâs 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 itâs hard to get going again. This helped. Itâs not a miracle drug so donât expect that, but itâs makes the transition easier and getting back on track easier. Itâs what I needed.My sleep wasnât necessarily bad, but it also improved. Iâve 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 âawakeâ even if I didnât remember it. Since taking the l-tyrosine itâs been consistently below 10%. Again, itâs 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 donât feel the need for a nap mid-day so thatâs a plus!The overall happiness was something that I read, but wasnât 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 Iâll take it!What I didnât 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 donât crave the sugar. No chocolate, no cookies, no ice cream. Iâm not saying I didnât indulge once in awhile, but I didnât 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. Iâm not sure if it would work differently without the B Complex or not, but I figured Iâd mention it just in case.Hope my feedback helps anyone else considering taking this!

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.

Works great when taken with perscription!!
I’ve been using Now supplements for a while now, and here’s my take on it: when paired with prescribed medication, it’s been a game changer. I’ve noticed a significant improvement in how I feel throughout the day. Wheter it’s increased energy levels, or better overall mood levels, the combo has truly made a differencein my daily life.However, when taken on it’s own, I id’nt notice any significant change. It seemed to blend with my daily routine without making a standout impact. That said, when used as an addition to my prescribed med, the results were unmistakable!
