N-Acetyl Cysteine (NAC) is a supplement form of the amino acid cysteine, and it has several potential health benefits due to its ability to increase the body's production of glutathione, a powerful antioxidant. This makes it effective in combating oxidative stress and reducing damage caused by free radicals.
NAC is also beneficial for respiratory conditions, heart, skin, and neurological health as well as aid in detoxifying the liver and body from other toxins and heavy metals.
