Хорош Good

Скажу сразу, эффект есть, не плацебо. Вполне ощущается. Но настроение не очень-то повышает, иногда даже наоборот. Тем не менее с ленью и апатией борется. Если хочется спать, валяться в постели, он неплохой помощник. Слегка бодрит, добавляет интереса к жизни. Делаешь дела с большим аппетитом, короче говоря мотивирует. Это мое ожидание оправдал. Но не все так гладко, поскольку тирозин оказывает действие еще и на адреналин и норадреналин, он способен усилить тревожность I will say right away, the effect is there, not a placebo. It feels good. But the mood is not very high, sometimes even Vice versa. Nevertheless, he struggles with laziness and apathy. If you want to sleep, lie in bed, he's a good helper. Slightly invigorates, adds interest to life. You do things with a great appetite, in short, motivates. This is my expectation met. But not everything is so smooth, because tyrosine also has an effect on adrenaline and norepinephrine, it can increase anxiety

Second product I’ve used from Source Naturals and very impressed, love their packaging and they always have potent products with ingredients that are WHAT THEY SUPPOSED TO BE. Love this product, no taste, the size of the pill is fairy big but this product helps with motivation and anxiety.

I love Source Naturals L tyrosine. They use high quality ingredients, tablet size is normal and easy to take. It does not taste like anything or have a scent. This supplement has a lot of good benefits. It gives me energy, boosts my mood, speeds up my metabolism and helps suppress my appetite. I take it often!

I noticed the first day I did feel like I had a little bit of more energy it wasn't like speedy type of energy but I just felt like more awake, I must have needed this! it's a precursor for so many things that we need in our body to function properly and anyone could use this in really benefit from it because most likely with everyone's diet in this day and age we're not getting enough I definitely recommend this for anyone any age if you're feeling sluggish I would try this like I said it's not going to make you feel speedy but the next morning I woke up more awake than I've ever felt or that I felt in a long time!

Interesting nootropic, I use cycling on and off. I get benefits in terms of concentration and task accomplishment (works to modulate dopamine). I notice for training at gym i feel more locked in. Quality and price seem good compared to other manufactuers. Size is on the bigger side but no problem for me. I really like this supplement

Used it according my doctor’s prescription to help my thyroid to work well. And after the month it becomes better, just ask your doctor if you need it

I can literally feel the effects of L-Tyrosine after a week of using it. I’m happier, more focused and they are easy to take.

For me, with a fairly weak functioning thyroid (per the "normal" lab standard ranges), and thyroid-related issues all my life, without ever any doctor saying, hey, maybe it's your thyroid that's creating all these reproductive and adrenal issues, when I eventually got diagnosed with Hashimoto's, I did not want to take the true thyroid hormones. I still don't. I want to manage it easily, bring it back into balance naturally, slowly, without further stressing my thyroid and adrenals and reproductive system out. And I have managed to reduce by half all the antibody markers, in 3 months, with zinc and selenium. But when I started taking this, my body started experiencing things it never did before, like my insides started to come alive! This little pill, quite strong for someone like me, even with all the hormonal imbalances, hashimoto's, and fertility issues, the ingredient in this pill is like a hard-reset, giving me years of fertility back, as it re-energized my entire hormonal panel, including adrenals. I am not taking it every day because I forget, and can tell you that I feel the difference when I don't. Even my mood is more balanced the next day! Plus, I take it in the evening, before bed, and I sleep better, too! I don't know what else to tell you but there's kind of a lot of huge benefits from this one little, yet mighty, pill. And total DISCLAIMER!!! I'm not a doctor, I am not telling you that this will work for you as it does for me. I am not encouraging you to take this, or to take this instead of your thyroid hormones, or instead of your anti-depressants, or your sleep/relaxation pills. I inform myself, I read, I do research (the scientific publications kind), I read nutrition books, and I am very interested in functional medicine as I believe that the entire body works together, including our brain and mental health, and our modern medical system that keeps obsessing with looking at each "system" individually seems antiquated and barbaric. My sincere advice to y'all is to find yourself a Functional Medicine Doctor, sometimes known as an Integrative Medicine Doctor, and have them look at your body, your WHOLE BODY and MIND, your symptoms in the larger perspective of your entire being, stress included. Go from there :-) Best of luck and best of health to y'all!

Not just my imagination -- I really do have more energy, or at least I don't have the slumps that I used to have. Didn't take long to work either.

I am particularly satisfied with this amino acid and believe I have been needing it. I will monitor how long I take it. I felt the difference immediately. I think it helped me in my brain activity in so much as it helps produce the proteins needed.

I was really surprised when I tried this product. With this quality at this price, it's a product that I'm not ashamed to introduce to anyone. I can't help but be unwilling to order this product again
