What is N-Acetyl-L-Cysteine?

N-Acetyl-L-Cysteine is a stable, bioavailable form of L-cysteine, an amino acid that the body uses to produce antioxidants and enzymes crucial for detoxification.
NAC helps replenish glutathione levels, essential for protecting cells from oxidative damage caused by stress, toxins, or pollution.
This compound has been used in both clinical medicine and nutritional supplements due to its versatility and effectiveness in promoting internal balance and protection.

Nutritional Composition and Function

Glutathione Precursor

NAC serves as a key precursor to glutathione synthesis, one of the most important antioxidants in human cells. Glutathione helps neutralize free radicals, supports immune activity, and detoxifies harmful substances in the liver.

Amino Acid Support

As a sulfur-containing amino acid, NAC supports protein structure, enzyme activity, and metabolic function. It helps maintain the integrity of cellular membranes and promotes recovery from oxidative stress
