N-Acetylcysteine

Description:
N-Acetylcysteine (NAC) is a derivative of the amino acid cysteine, characterized by the addition of an acetyl group to the sulfur-containing thiol group of cysteine. It is commonly recognized for its role as a mucolytic agent, helping to break down mucus in respiratory conditions, and as an antioxidant due to its ability to replenish intracellular levels of glutathione. NAC is soluble in water and has a slightly bitter taste. It is often used in clinical settings for the treatment of acetaminophen overdose, as it helps to prevent liver damage by restoring glutathione levels. Additionally, NAC has been studied for its potential benefits in various health conditions, including psychiatric disorders and chronic obstructive pulmonary disease (COPD). Its safety profile is generally favorable, although side effects can include gastrointestinal disturbances. As a supplement, it is available in various forms, including tablets and powders, and is often used to support overall health and wellness.
