Slow ServiceAug 29, 2010 If you are looking forward to get your items two weeks after you order it. then go ahead and wait . GNC has it the same price but much faster. It would probably be 5 minutes from home. It definitely wasn't worth it
It has potentialJul 26, 2010 My daughter has been taking this for a few weeks now to help improve energy and endurance. Her muscular weakness condition makes many activities hard for her to do. She has reported, and I have observed, some small improvements in her abilities since she began taking this product. The results are very individualized (I know others that have tried this amino acid), so you won't know the affect it will have on you unless you try.
I also tried Tyrosine (not the acetylated form, though) and found that it made me more alert late in the day and especially at night. I could not fall asleep until late at night, had lucid dreams, and woke very easily. I got limited sleep while taking Tyrosine, but I DID NOT feel tired. I think the effect of being more alert results in the perception of more energy, which results in being more active, which can have a positive impact in many ways. Try it an post the result you observe!

Folic Acid?Mar 26, 2010 N-Acetyl L-Tyrosine is N-Acetyl L-Tyrosine, so any brand will do, as long as it comes from a reputable company. For some reason, however, Source Naturals (a company I have always considered to be reputable, so I'm assuming this is just an error in someone's judgment that will be corrected sooner rather than later) has elected to add 400 micrograms of folic acid to each 300 mg tablet. Why do that? How does such a large amount of folic acid contribute to the metabolism of N-Acetyl L-Tyrosine? Other manufacturers add B-6, but SN is the only company I can find that adds folic acid. Given that high doses of folic acid are now implicated as a cause of lung, prostate and colon cancers, I cannot fathom why anyone who takes a multivitamin or a B-complex (because most contain at least 400 mcgs) would add to their risk by taking this product.

Didn't last for the long haulMar 19, 2010 Took this to help with sleep and depression as I was trying to avoid a prescrption drug. Seemed to work for a few months but then didn't notice much after that. Kind of felt like I did before taking it. Was not interested in increasing dose as that scares me. Stopped taking it because there was a possibly that it would interact with a med I was to start taking. Did not notice any withdrawl or adverse side effects from stopping it.

Do You Have a "Grasshopper" Mind?Dec 18, 2009 This product has significantly increased my energy and focus. During the winter months, I always found it hard to wake up in the morning, and never really quite felt like I "woke up" as the day went on. The impact of the N-Acetyl-Tyrosine was instantaneous. After just a few days, I was waking up an hour before my alarm clock had been set for. I would suggest taking it no later than noon, each day, as taking it later may prove to interfere with sleep. I take 2 300 mg tablets each morning, and 2 more with lunch. As a coach and author on "Productivity" this supplement has certainly earned a spot on my list of "must have's" for peak performance.
