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

I started taking this a few months ago, i try to take probably 1-2 a day and i've noticed a slight increase in focus.I was previously struggling to fall asleep by 3am and get anything done but after a few months of this i've slowly improved and have on occasion even fallen asleep before midnight feeling more relaxed.I don't think this will help you on your on, you're not going to take 3 of these a day and match like prescription drugs for improving focus and memory but couple with improved lifestyle choices this helps a lot. People might call it placebo effect, but honestly anything that helps drive to build accompany good habits is a good thing by me.Just be regular in taking it and find 1 or 2 life improvements goals you can do with this, my deal was running which i think has helped a lot. Honestly i've tried running before and would always lose interest, but with this i genuinely feel more focused in the activity and starting in other activities as well.Exercise and good sleep will probably help more, but I feel this will help you get those small steps in.

I was hesitant to try tyrosine because some reviews say it made people very angry. After years of wondering, I decided to try it.It's best taken when I woke up since it causes some slight restlessness.Let me tell you, I had zero desire or motivation before starting these, but after a month or so of taking it once a day, I noticed I'm able to learn new things faster, and stick to it. I noticed no anger or mental status changes other than feeling more motivated.Sometimes it gives me slight acid reflux. It has no taste at all. The pill quality looks clean and nothing was damaged. I heard it's a precursor for dopamine so I started taking itOnce I noticed the improvements, I stopped taking it like people suggested, so I don't go over my sero/dopa balance. If I feel like I want to quit my normal routines, I take one again to top it off.This isn't a miracle pill obviously, but if you have things you keep putting off that you genuinely wanted to do, tyrosine seems to enhance that motivation for me. Maybe it can for others too, hopefully!

This product has changed my life! I’ve been suffering from extreme brain fog and fatigue after the pandemic which was also around the time I entered my 40’s and peri-menopause. After so many doctors appointments, blood panels to check for vitamin deficiencies and even being diagnosed with ADHD, nothing helped. All my panels came out normal. HRT helped a bit but not until I started taking this product do I now feel like myself again! I never thought or knew much about amino acids. Highly recommend. Take first thing in the morning and wait 30 minutes before having breakfast. Not a doctor. Only sharing my experience.

While skeptical at first, these supplements do give me a little boost of energy in the morning when taken on an empty stomach. It lasts for about 2 hours and a half hours, but when combined with caffeine I feel it more so. However, some days, especially after a big meal, I do not feel the effects at all.

Got this to treat my ADHD while I wait to get medical treatment. It works pretty well. I would say def take it after a meal. Effects arent that strong but does help. Usually last about 4 - 5 hours

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.
