The Claim
There is a belief that taking NAC supplements can prevent the onset of influenza due to its immune-boosting properties.
Origin
This myth likely arises from misunderstandings of NAC's role in immune function and its effect on viral infections.
What Science Says
While NAC may help reduce the severity and duration of flu symptoms once contracted, evidence from RCTs does not support the claim that it can prevent the flu altogether. Studies show that NAC can modulate immune responses, but its preventative efficacy against the influenza virus is not substantiated.
Verdict
Misleading
