L-Tyrosine is a conditionally indispensable amino acid required for the production of the neurotransmitters dopamine, adrenaline, and noradrenaline, as well as for the skin pigment, melanin. Noradrenaline (norepinephrine) and adrenaline (epinephrine) are the main actors in the body's response to acute stress and, along with dopamine, help to support a positive mood and mental alertness. In addition, L-Tyrosine is especially critical for the normal function of the thyroid gland.

Suggested Use

Take 1 capsule 1 to 3 times daily, preferably between meals.

So I have been using this brand for quite some time. It's a great source of tyrosine and it really does the job, or should I say did. As with most good things the most important thing is balance. I have been eating L-tyrosine 750 mg daily for about 3 months, I would say the first 3-5 weeks were absolutely amazing, but then I started to get a tolerance, they still worked fine for focus though, but later on I got more and more sluggish. There might be some very good reason for this, the first one could simply be over-consumption of tyrosine, which in turn may have made more dopamine than noradrenaline, and too much dopamine can - contrary to popular belief - increase fatigue, especially when noradrenaline is lacking. The second thing I found when I did some research is that L-tyrosine should be taken with 5-htp or tryptophan, if 5-htp then about 10 to one tyrosine/5-htp. I personally felt a little better after I started taking 100 mg 5-htp in the evening and my l-tyrosine in the morning, however I will stop both for a few weeks and check how I feel without them. But all in all this is a wonderful product and helped me keep alert while studying for my finals.

Thanks for your feedback!
