N-Acetylcysteine (NAC) is a stable form of the essential amino acid cysteine. It is a sulfur amino acid that acts as a stabilizer for the formation of protein structures and supports the formation of glutathione. Glutathione is a powerful free radical neutralizer that also helps maintain normal, balanced immune function. Quercetin is a natural free radical neutralizer that supports healthy immune function during the seasonal cold season. Laboratory studies have shown that quercetin may also help promote healthy respiratory function. Zinc has been added for its immune-supporting properties.
