5.0 out of 5 stars For some types of ADD, July 29, 2009

This review is from: Source Naturals N-Acetyl L-Tyrosine 300mg, 120 Tablets (Health and Beauty)

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.

5.0 out of 5 stars Do You Have a "Grasshopper" Mind?, December 18, 2009

By 

Vincent Harris "Author of The Productivity Ep... (Trenton, MO USA) - See all my reviews

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.

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.
