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

By	William H. Jeffrey "Summa Nulla" (Glendale, CA) - See all my reviews (REAL NAME)

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 Great for Winter Depression, January 3, 2007

By	Jack Douglas Kelley (Portland, OR USA) - See all my reviews (REAL NAME)

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.

5.0 out of 5 stars Great for mny types of ADD, August 1, 2009

By	Memento Mori (East Coast) - See all my reviews

I myself have horrible ADD, I have a bachelor's in psychology but didn't realize that I had the condition until I was in my junior year. Then I began taking Adderall for a few months but I only took like 15 mgs and only when I had to since I don't like meds. Then I tried this and it worked just as good for $20 instead of $120 for 4 months while in school. Then destiny struck me when I was researching my brother's GI condition. We should be eating a paleolithic diet because our ancestors did. We have shovel shaped teeth and many of the traits of a Native American or Irish person- typically a blood type O, this is the oldest blood type. I stopped eating wheat and I got way better over the course of 4-5 months and I'm still getting better. I encourage you to look up the blood type diet, it's completely free since there is a complete electronic food database and how the foods affect the blood types differently.

Why would a Dr give you all the information to use a diet when he was selling books? Only because it works consistently so people want to learn more about it.

It all has to do with lectins, or plant and animal proteins:
"One day toward the end of 1945, looking at this table in the second English edition of Landsteiner's book, I was seized with the idea that if such extracts could show species specificity, they might even show individual specificity; that is, they might possibly affect the red cells of some individuals of a species and not affect others of the same species. Therefore, I asked one of my assistants to go out to the corner grocery store and buy some dried lima beans. Why I said lima beans instead of the more common pea beans or kidney beans I shall never know. But if we had bought practically any other bean we would not have discovered anything new.

The lima beans were ground and extracted with salt solution. The resulting extract agglutinated erythrocytes of some human individuals, but those of others only weakly, if at all. It was immediately evident that the differences were correlated with blood groups.

The ease with which this discovery was made misled me, and aside from a rather oblique reference to it in the second edition of my Fundamentals of Immunology,(13) which I was working on at the time, I did not publish this observation until 1949, when I reported on an investigation of 262 varieties of plants belonging to 63 families and 186 genera.(14)

The first plant found to be blood-group specific was Phaseolus limensis, which, however, was not reported in detail (14) until 1949. In 1948 Renkonen (15) published an account of his independent studies of 57 species belonging to 28 genera. He reported Vicia cracca extracts to be specific for the blood-group-A antigen, and Laburnum alpinum, Cystisus sessifolius, and Lotus tetragonolobus to be specific for the H blood-group factor. Krupe published a large number of original observations. Makela (8) published a monograph giving the results of his tests on a large number of seeds, and Tobiska (l6) and Adamkova and Tobiska (17) published their results of tests with 200 plants. A complete list of all the plants tested in my laboratory was recently published." Five reviews have appeared (2,4,8.10,19)

I proposed that these blood-antigen-specific plant agglutinins (which are also specific precipitins) be called "lectins" -from the Latin legere, to pick out or choose -intending thus to call attention to their specificity without begging the question as to their nature."
