N-Acetyl L-Tyrosine is a more rapidly absorbed and bioavailable form of the amino acid L-tyrosine. L-Tyrosine is a precursor to the neurotransmitters dopamine, norepinephrine and epinephrine, and to enkephalins, special peptides that subdue messages of physical discomfort.

For some types of ADDJul 29, 2009
By Summa Nulla I have been diagnosed with ADD (finally,after my 50th birthday). I was online and ran across the web site of Dr. Daniel Amen (not religious "Amen" but that's his name). He is a pioneer in ADD and has published many books and has specials on PBS from time to time. His web site, [..] , includes much information for the lay person, including a couple of easy online tests that might help a person start the diagnosis process for him- or herself. I have read several of his books for laypeople and I recommend them. (I have no connection with Dr. Amen or his clinics.)
To make this short, my particular type of ADD (there are at least six) responds to medication. Since I didn't want to go to my doctor and ask for Ritalin or something similar, I tried the recommended supplement, L-Tyrosine. I found that plain L-Tyrosine did nothing, but after further research I found N Acetyl Tyrosine helped --not just marginally, but obviously and greatly--and it was noticeable in less than two days. It has no stimulating effect. It needs to be taken on an empty stomach, like other amino acids.
Don't take my word for this, but do your own digging. Even if the ADD type you are researching doesn't respond to the N Acetyl Tyrosine, you will know enough to deal with the problem yourself in some cases, or when and where to seek help.

Do You Have a "Grasshopper" Mind?Dec 18, 2009
By Vincent Harris
"Author of The Productivity Epiphany"
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.

Great for Winter DepressionJan 04, 2007
By Jack Douglas Kelley I've been taking these from September to March for 12 years. They take three days to get full effect and they work great for seasonal depression. I couldn't live in the Northwest USA without them.

Didn't last for the long haulMar 19, 2010
By Kelly R. 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.

The best formulation for absorption I've seen in an L-tyrosine product.May 19, 2011
By eCognition Along with the Folic acid (400 mcg) and the Vitamin B-6 (25mg; as pyridoxine HCL), you get the 300mg of N-Acetyl L-Tyrosine. With L-Tyrosine, I wanted to make sure I absorbed as much of it as possible and this formulation was mentioned many times in various websites that focus on cognitive enhancement techniques as being one of the best (others requiring the addition of other amino acids that come as standalone products). L-Tyrosine, taken with other cognitive enhancers, is very effective in helping you focus and also in keeping the stress down when your doing intensive studying. Taken alone and under normal everyday circumstances, the benefits are not seen as much (if at all). I've read hundreds of testimonials from numerous sites and the consensus seems to be that if you "think" it might be helping, then there's probably a placebo effect going on, but if you "know", then you know, as in my case. I'm usually very skeptical, but when I started taking these, I noticed a considerable effect on my mood and focus. But then again, I was hardly sleeping and working through loads of study. I still keep these during those periods in time, and they are very effective.
