Description
L-Cysteine is a thiol-containing non-essential amino acid that is oxidized to form cystine. This amino acid provides resistance to the body against all harmful effects, because it is responsible for building up white blood-cell activity. Cysteine is also necessary for the proper functioning of the skin and helps your body recover from surgery. Cysteine is also used to produce Glutathione and Taurine.
