What does it do?

L-cysteine hydrochloride is the hydrochloride form of the amino acid cysteine, primarily used as a mucolytic agent or to promote mucus secretion. This ingredient helps to thin mucus in respiratory conditions, aiding in cough relief.

L-cysteine hydrochloride breaks the protein bonds in mucus, thinning it. As the mucus becomes thinner, it is more easily expelled from the airways, facilitating easier breathing.

Approved uses differ by product. Check each product's information for its actual use.

Good to know

Unlike other mucolytics, L-cysteine hydrochloride is derived from an amino acid and acts by altering the chemical structure of mucus. This results in simultaneous mucus secretion promotion and mucolytic effects.
