It really works for me.
This stuff works. It helps for the awful crash I receive after having to take prescribed amphetamines for my ADHD. It just improves my mood overall. I drink it 3 times a day and I've never been better. First time, I ordered 1 bottle, second time 2 bottles, and now I ended up getting a 3 months supply because of how amazon is randomly cancelling their orders with the excuse that its supposedly undeliverable because it was damaged. That's how vital this product is to me. It's just great.

I’m really impressed with the results!
I've been using L-Tyrosine supplements for a few weeks now, and I’m really impressed with the results! This product has been a great addition to my daily regimen, providing noticeable benefits in mental clarity and focus. The 500mg dosage per capsule seems to be just right for me, offering a boost in cognitive function and mood without any jittery side effects. I’ve found that it helps me stay more alert and better manage stress throughout the day. The capsules are easy to swallow and don’t have any unpleasant aftertaste. The quality of the L-Tyrosine is evident, as I’ve experienced consistent results with no digestive issues. The packaging is convenient and informative, making it easy to incorporate into my routine. Overall, I highly recommend this L-Tyrosine supplement to anyone looking for a natural way to enhance mental performance and mood. It’s a reliable and effective product that delivers on its promises!

Positive Results for me
I recommend for ppl who’s doc recommends … My doctor recommended these after my lab work shows my thyroid works slow. I have been taking for over a year and my quality of life has improved - I’ve lost 30lbs, I have energy thru the day, I haven’t been sick nearly as much in a year - I can tell if I have missed a block of days based on body fatigue. I’ve also noticed other skin issues clear up, which I attest to my thyroid getting support ???

GAME CHANGER!!!
I’m 45 years old and have been going through perimenopause and it has caused absolutely no energy at all! It has been a 4 year struggle for me. This supplement has been an absolute game changer. I take 2 as soon as I wake up and I am telling you it is like night and day! My mood is better and my natural energy is way up. If you are struggling like I was then YOU MUST BUY AND TAKE EVERY DAY!

Great Experience So Far
I ordered this supplement for a mental boost during exam preparation and taking my final exams. I’m a grad student with ADHD and some of my exams can be up to 6 hours long so I really wanted something that would help with my focus, mental endurance, and motivation. Additionally, prescribed stimulants can make me anxious and crash later in the day and I’ve read that l-tyrosine is helpful in alleviating these side effects. I have to say I think this really helped. I did a lot of research and found so many recommendations for l-tyrosine. It helps the body produce dopamine. I’ve used this brand for other supplements before and have had a great experience with it. I followed the directions and took it between meals 2-3x per day. I must admit that did take some other supplements as well, so I will update this review as I isolate this supplement to see if it’s still helping. Definitely recommend giving it a try. But absolutely do your research and be wary of taking anything long-term. Supplements aren’t regulated to the same extent as medications. There’s great information on NIH studies and Reddit pages so I recommend starting there. Everyone’s body/chemistry is different and we react to things differently so try not to have expectations and just see how your body responds. Be especially cautious if you have thyroid issues. I am no doctor but this is just coming from information I’ve read.

Check with your doctor before taking...
While I can't speak to the performance of this supplement, I can say that you should definitely take the advice and speak with your physician prior to taking, especially if you're on other medications. After one dose, I experienced mildly elevated BP. After another dose the next day, my blood pressure increased even more and I started experiencing heart palpitations and increased heart rate. After another dose (one pill) on day three, my blood pressure & heart rate were high to the point where I needed to seek medical attention. Needless to say, I stopped taking the supplement and simply warn you to be cautious and definitely talk to your physician before taking this.
