How do i use NAC to clear nasal congestion

To use N-acetylcysteine (NAC) for clearing nasal congestion, here are the key insights from Andrew Huberman:

• Dosage: Take 600 to 900 mg of NAC three times a day. You can adjust between different brands, but the total daily dosage should range within this range.
• Mucolytic Effect: NAC acts as a powerful mucolytic, meaning it helps thin mucus and promotes its expulsion. This can significantly relieve sinus pressure and congestion.
• Avoid Decongestants: NAC is preferred over over-the-counter decongestants, which can cause rebound congestion (where symptoms return worse after the medication wears off) and may be habit-forming without offering additional health benefits.
• Long-term Benefits: A study mentioned suggests that taking 600 mg of NAC twice daily for six months may lower the chances of contracting influenza, showing its potential for reducing illness frequency as well 1.

Before starting any new supplement, consult with a healthcare provider to ensure it's appropriate for your situation.
