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!

I usually don’t have any issues swallowing tablets, but these tablets aren’t just big. They’re also made from very hard materials and quite thick. If they were flexible it probably wouldn’t be such an issue, but now it is. Product itself is fine, but the swallowing isn’t pleasant

I have been taking this for 3 weeks plus. I have hypothyroidism. A previous natural doctor recommended L-Tyrosine. L-Tyrosine is a precursor for making thyroid hormones in the body . I take it in the morning because,for me, it’s stimulating . That’s a good thing as it’s also seems to be lifting my mood. In general, I feel it’s been safe. I wouldn’t take later in the day , as it may affect ability to sleep.

I usually take this before heading to the gym. Works great with my pre workout. Seems to improve focus and get you in the zone. Also works great if you need to get stuff done for school/work. Highly recommended. Great price as well ;)

This is really helpful with my hypothyroidism. I use to take 1 tablet with Bladderwrack, but I found that taking 2 tablets works best. My digestion feels better and I’m more energized and focused.

I love Source Naturals, I have had many of their products and can recommend them . I also trust iHerb to only sell the best products & shipping time is terrific.

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

Some additional supplements might cause stomach bloating or other issues. I haven't had it yet with this product. I use this along with my pre to assist with all that neurotransmitter stuff with muscle activation.

I haven't noticed a massive change in mood, but I do feel like it makes a smaller difference to my day, so I will continue to use

While I rarely experience adverse events due to supplementation, the one-time use of this item resulted in a pronounced headache, as warned in many sources discussing tyrosine.
