The meeting of the Advisory Committee on Complementary Medicines (ACCM).
At this meeting, the committee's advice was sought on a proposed maximum daily dose for cysteine, cysteine hydrochloride and cysteine hydrochloride monohydrate. The TGA proposed a maximum daily dose of 450 mg L-cysteine. This equates to 585 mg cysteine hydrochloride and 652 mg cysteine hydrochloride monohydrate.
The committee noted the European Chemicals Agency (ECHA) Derived No Effect Level (DNEL) for L-cysteine, data from the Norwegian Scientific Committee for Food Safety (VKM) evaluation and the Australia-New Zealand Food Standard 2.9.4. The committee considered that a dose restriction of 750mg cysteine for adults and 500mg cysteine for children could be appropriate.
