Antioxidant Support : N-acetyl-cysteine is a precursor to glutathione, a powerful antioxidant in the body, which helps fight oxidative stress and promote cellular health (Free Radic Res. 2018 Jul;52(7):751-762 ).

Optimized Liver Function : NAC as a precursor of Glutathione contributes to the detoxification of the liver, supporting its ability to filter toxins and protect the body from damage caused by free radicals (Biomed Pharmacother. 2003 May-Jun; 57(3-4): 145–155).

Respiratory Health : NAC has been shown to help reduce the viscosity of mucus in the lungs, making breathing and expectoration easier in conditions such as chronic bronchitis or respiratory diseases (Curr Neuropharmacol. 2021 Aug 11; 19(8): 1202– 1224.).

Immune System Support: NAC acts on the immune system through its antioxidant action and its ability to modulate the immune response (Free Radic Res. 2018 Jul;52(7):751-762).

Reduction of Muscle Fatigue: Useful for athletes, NAC can help reduce muscle fatigue and promote post-workout recovery, improving physical performance (J Appl Physiol (1985). 2004 Oct;97(4):1477 -85).

Protection Against Heavy Metals: Thanks to its chelating properties, NAC can bind to heavy metals, facilitating their elimination from the body (J Nutr Metab. 2021; 2021: 9949453)

Psychological Health : It has been observed that NAC can contribute to improving mood and reducing symptoms of anxiety and depression (J Nutr Metab. 2021; 2021: 9949453).
