Both me and my kid take this, and it surely helps the both of the keep calm. The benefit seems more for my kid who has a tendency to easily get anxiety and falls into bouts of OCD. His mood swings are less now and is able to concentrate way better in class. Both of us take 2 pills a day. Since it works I would say quality of the ingredient is good.

I have experienced elevated levels of dopamine, but I can't confirm that this product is the reason for that. I take a lot of supplements, and this has been a recent addition to an already huge stack of pills. Quality and price seem excellent though, and for individuals that are under stress, may want to experiment with this. Should be taken on empty stomach with perhaps a B vitamin complex. Experiment and take notes of changes, so you can determine what's right for YOU!

I like the quality of this supplement at the price that herb has. My nutritionist recommended it for help with weight training and help with body composition. I am adding it to a low carb diet and already know it is beneficial. The pills are easy for me to swallow and don't have a taste.

L-tyrosine has been shown to be effective in improving cognition in the presence of acute stressors, often found in high-intensity exercises such as bodybuilding or exercise. In particular, L-tyrosine can dramatically increase the production of norepinephrine and dopamine, helping to improve attention and cognition.

Out of the several different brands of L-Tyrosine supplements I've tried I've found this one to be one of the most effective. It really shined in it's ability to promote a state of alertness in a somewhat sleep deprived state.

My daughter studied neuroscience and told me that this is an essential nutrient for brain health. I Used to purchase this from my local health food store and found it here for a much better price. Thanks iHerb!
