NAC supplementation is an obvious solution when the production of a chemical has been inhibited by unnatural sources.

In my case, it is fluoroquinolone toxicity.

NAC supplementation is a collaboration of nature and chemical supplementation it is not an "engineered nanoparticle".

Analysis and Risk of Nanomaterials in Environmental and Food Samples

Abstract
Engineered nanoparticles (ENPs) have found broad application in textile industry, due to their antibacterial, antimicrobial, water resistance and protective properties. Unfortunately, despite the wide dissemination and application of ENPs, their toxicity and potential harmfulness have not been thoroughly investigated and/or eliminated. Consequently, there is an urgent need for defining the most appropriate analytical methods for monitoring such particles on textiles. Several sources should be of major concern: materials treated with ENPs, wastewaters from industrial, hospital, hotel and domestic laundries, as well as the waste produced from all mentioned sources including textiles themselves. Therefore, this chapter reflects the most important applications of ENPs on textile materials and addresses all relevant sources of environmental pollution and threats to human health. In addition, the most important analytical techniques for monitoring of ENPs on textile materials and in textile wastewater samples, with the perspective of preservation of environment and human health, are presented.

Supplementation with NAC is merely replacement of a chemical that is not being sufficiently produced due to systemic toxicity.
