💊 N-Acetylcysteine (NAC): From Mucolytic to Glutathione Precursor

NAC is a substance with two important roles - let's look at what it is and how it works

N-acetylcysteine (NAC) is an active substance with two key roles: a mucolytic (thins mucus) and a precursor of glutathione - an important antioxidant. It is used in medicine and supplements.

NAC is popular for airway support and antioxidant protection. Let's look at its role, uses and precautions.

Key idea: NAC is a mucolytic and a glutathione precursor. It thins mucus, supports antioxidant protection and detoxification. It is used in medicine and supplements.

💊 What is NAC

NAC is a derivative of the amino acid cysteine. It is used in medicine as a mucolytic and in supplements as an antioxidant.

Role: NAC does two things: thins mucus in the airways and helps the body produce glutathione.
Status: NAC is used in clinical practice (e.g., for paracetamol poisoning) and in supplements.

🫁 Mucolytic

NAC is known as a mucolytic - a substance that thins mucus.

Mechanism: NAC breaks bonds in mucus, making it less viscous. This eases phlegm clearance in airway diseases.
Important: in airway diseases, NAC is used as prescribed by a doctor. Supplements are not a substitute for treatment.

🧬 Glutathione

Glutathione is one of the body's main antioxidants. NAC is its precursor.

Mechanism: NAC helps the body maintain glutathione levels. Glutathione participates in detoxification and cell protection.

🛡️ Antioxidant

By supporting glutathione, NAC enhances antioxidant protection.

Role: glutathione neutralizes free radicals. Supporting its level through NAC helps reduce oxidative stress.
Nuance: NAC's antioxidant effect depends on the dose and individual factors.
