Hi all, Like most of you I also have low glutathione. Since cysteine is a precursor to glutathione, I wonder how to raise cysteine? I have read that cysteine does not survive the trip to the cell through the digestive system very well. Most cysteine is broken down or altered somewhere along the trip. It seems that Raw milk is in a complete form which does raise Cysteine in the body. Unfortunately I can't take Raw milk because of some food sensitivities. And I also don't tolerate NAC (probably because of the heavy metals in my body) Are there any other options left to raise cysteine? Thanks in advance!
