Does CBS mutation expression mean both high ammonia and high sulphites??


I have heterozygous CBS 360. I did take gluthathione, NAC to remove the mercury. I did had bad reaction to this and hence concluded that I am intolerant to sulphur.Even further confirmed by low molybdenum.

But I am not sure about Ammonia. I read somewhere that ammonia levels in blood cannot indicate high ammonia in body? Is that right?

any subjective or functional testing to determine high ammonia?

Cutler says intolerance to sulphur implies high cysteine? I dont understand how? what can be done to decrease cysteine so I can have more gluthathione?

Warm regards
