NAC Explained: Why This Powerful Antioxidant Supports Detox and Immunity
BALA BITES: NAC Can Help Reduce Flu Symptoms
As flu season ramps up, I always try to provide some remedies that are science-backed or backed by generations of practice (ginger tea anyone?).
One I haven't talked about is NAC, more formally known as N-acetylcysteine, an antioxidant supplement.
NAC could be your secret weapon this flu season.
Why?
It's gaining attention for its potential to reduce the severity of flu symptoms.
It’s no cure-all, but the science behind it is fascinating and worth exploring.
NAC, THE ANTIOXIDANT SUPPLEMENT
NAC is short for N-Acetyl-L-Cysteine.
It is a supplement that serves as a precursor to glutathione, one of your body’s most powerful antioxidants.
Glutathione is like a detox superhero, fighting off oxidative stress and inflammation.
When the flu strikes, your body can get overwhelmed by oxidative stress, which contributes to inflammation and fatigue.
N-ACETYLCYSTEINE (NAC) BENEFITS
With the right dosage, NAC:
- helps restore balance by boosting glutathione levels, which doesn’t just make you feel better—it can help your body handle the virus more effectively
- is a mucolytic, which means it helps break down and thin music, which makes it easier for your body to clear out congestion and expel virus-laden secretions
- reduces inflammation and is thought to be antiviral.
Why pay attention to this? Just look at this Axios graph on the prevalence of the flu.

NAC is backed by a landmark study that showed it significantly reduced the chance of experiencing full-blown symptoms.
While 79% of those in the placebo group felt sick, only 25% of those taking NAC did.
This suggests that if you catch the flu, NAC can make it much more manageable.
It could be a great addition to your winter wellness toolkit.
An extra layer of defense this flu season...in addition to a healthy, nutrient-dense diet.
NAC is considered to be generally safe, with a typical dose being 600 mg twice daily.
SUMMARY
- NAC boosts glutathione, your body’s detox superhero, helping to reduce inflammation and fight oxidative stress during illness.
- It thins mucus and clears congestion, making it easier to expel flu-related gunk and breathe better.
- Studies show NAC can reduce flu severity, with only 25% of NAC users experiencing full-blown symptoms compared to 79% in the placebo group.
