Came across this information on NAC:

Recent research shows that NAC can slow down or stop growth of Dupuytren tissue: Juergen Kopp et al. "N-Acetyl-L-Cysteine abrogates fibrogenic properties of fibroblasts isolated from Dupuytren's disease by blunting TGF-β signalling" J. Cell. Mol. Med. 10 (2006) pp. 157-165. This indicates the possibility of NAC "providing a basis for a therapeutic strategy in Dupuytren's disease and other fibroproliferative disorders." Since this study NAC has been tested also on patients. While the total number of patients is still too low for reliable statistics, first results are promising, e.g. to avoid extension of Dupuytren to other areas after surgery or, in one case, a significant reduction of Ledderhose nodules."

Most NAC comes from China and is produced from human hair and feathers. There is a non-animal derived version that is produced by Sigma under license from a German firm. The NAC from www.physicianformulas.com claims to be the German version.

Subsequent studies have shown that Lycopene by itself does not confer any medical benefit. When a trial was done using lycopene with one group and tomato powder with the second group, only the second group benefited. Cooked tomatoes have an altered chemical structure that is more beneficial than raw tomatoes.

I have a question. Is N Acetyl L-Carnitine different than just Acetyl L-Carnitine. I cannot seem to fine NAC, just ALC.......
