Info
Evidence
moderate
Timing
Together, no conflict.
How it works
N-acetylcysteine forms soluble zinc-thiol complexes that may increase zinc bioavailability in the intestine.
The pairing has been studied in immune support contexts. NAC provides cysteine for glutathione synthesis while zinc supports immune cell function through independent pathways. No antagonism has been reported.
What to do
Take together without concern. Both are commonly included in immune and antioxidant protocols.
