💊 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.
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.
Mucolytic
NAC is known as a mucolytic - a substance that thins mucus.
Glutathione
Glutathione is one of the body's main antioxidants. NAC is its precursor.
Antioxidant
By supporting glutathione, NAC enhances antioxidant protection.
Uses

| Antioxidant | Cell protection |
| Clinical | In poisonings |
Dosages

What matters
How to sensibly approach NAC.
Understand the role
NAC is a mucolytic and a glutathione precursor.
Follow the doses
In supplements, usually 600-1200 mg/day. Do not exceed.
Consider medications
NAC interacts with some drugs. Consult a doctor.
With diseases - a doctor
In airway diseases, NAC is as prescribed. Supplements are not treatment. More in the article on glutathione and NAC.
What is NAC?
N-acetylcysteine - a cysteine derivative. A mucolytic and a glutathione precursor.
What is NAC used for?
As a mucolytic for the airways and as an antioxidant through glutathione support.
Does NAC raise glutathione?
Yes, NAC is a glutathione precursor. It helps maintain its level.
Does NAC help with cough?
As a mucolytic, NAC thins mucus. With diseases - as prescribed by a doctor.
How much NAC to take?
In supplements, usually 600-1200 mg/day. Clinical doses - as prescribed.
Does NAC have side effects?
GI discomfort is possible. With high doses and interactions - a doctor's consultation.
Is NAC compatible with other supplements?
Often combined with antioxidants. With medications - check interactions.
Is NAC safe?
At recommended doses usually yes. With conditions and medications - a doctor's consultation.
What are the sources of NAC?
NAC is made synthetically from cysteine. There is not much in food, so supplements are used.
When to see a doctor?
With airway diseases, medications or conditions - a doctor's consultation.
