cysteine

[Guest guest]

I don't know if anyone can help me - I'm posting from the office and

all my records are at home, so I may have a few things wrong. My son

tested for low leves of cysteine, which the MD noted was consistent

with detox. We ignored that problem for awhile, while addressing

critically low tryptophan, high copper/low zinc, and messed up EFAs.

Now it is about 4 months after the initial testing, my son is doing

much better, though still emotional, occasionally flapping, and

socially unaware. The MD wants to do something to address the

cysteine issue, and has prescribed NAC. I have no idea what this is,

and unfortunately was working over the phone with the doc, addressing

lots of issues, and never got a clear answer on it. Any ideas on

either what this NAC stuff is, or what the issue is with low cysteine?

Many thanks.
