this brings in a third study by the same group:
unfortunately, this remains all about sulfur, when i want to be looking at cysteine conversion. but, the conclusion is clear enough:
- if you get sufficient methionine and insufficient cysteine, your body will convert the methionine to cysteine.
- you get sufficient cysteine and insufficient methionine, your body will recover methinione from homocysteine.
- if you get sufficient levels of both, your body won't convert the methionine to cysteine and won't recover methionine from homocysteine
i'm aiming for #3, because i don't want the conversion - i want the methionine to do it's thing as a methyl donor and dna precursor and i want the cysteine to exist in sufficient amounts to convert to taurine & glutathione.
this third study seems to verify that i'm doing it right, but the number they present is unconvincing. so, can i find better data?
