NAC protocol for colds
Sources:
The described NAC protocol is 1,200 mg daily for prevention and 900 mg three times daily during a cold.
- Prevention: Take 600 mg twice daily. In the cited study, participants took this dose for six months; the reported influenza rate was 25% among NAC users versus 79% with placebo.
- Treatment: Take 900 mg in the morning, late morning, and afternoon, and avoid taking it close to bedtime because increased mucus flow disrupted sleep.
- How it may help: NAC is a precursor to glutathione and acts as a mucolytic, loosening mucus; Huberman described relief of sinus pressure and congestion.
