NOW Foods Supplements, L-Tyrosine 500 mg, Supports Mental Alertness*, Neurotransmitter Support*, 120 Capsules

Verified with Now Foods using the expiration date and lot number that I got the legit product through Amazon and I did. Using this under a drs care along with Seroplus to replace Zoloft .

Recommended to me by my psychiatrist to take along with my Vyvanse (20mg), twice a day in between meals. Definitely notice a different in focus and motivation when taking it with or without my Vyvanse. I work full time and am in grad school, so I have to lock in most of the day to get things done on time.Not sure if related - but I also lost about 25 pounds over a few months without changing anything (diet, activity level, etc.). I did regain it all back over the winter due to not taking supplement + lower activity.

Iv lost 15pd in 2 weeks after taking this! Just came back to get some more. Does everything else it says.

If you have ever taken Adderall or Vyvanse or some kind of ADHD medication and you are looking for something to replace it and have the same effect, it’s never going to happen with ANY product you can find on Amazon, those aren’t meant to be able to be replaced by an over the counter pill, with that being said if you are not used to having a prescribed Med this might do you wonders, it’s worth a try, 4 stars

Take one every night and makes me sleep better

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.

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!
