NAC N-acetyl-L-cysteine is a derivative of cysteine belonging to the group of endogenous amino acids.

It is a carrier of free thiol groups (-SH), which have the ability to bind free radicals.
It has a low molecular weight, which is why it easily penetrates cell membranes.
Reaching the inside of the cell, it releases cysteine necessary for the synthesis of glutathione with antioxidant properties.

Thus, it prevents cell damage and the development of inflammation.

NAC is used as a means of increasing glutathione levels and supporting cell defense against toxins released during the decomposition of drugs (paracetamol) and free radicals.
