NAC provides cysteine while glycine provides another rate-limiting precursor; together they are more effective at raising glutathione than either alone (GlyNAC protocol).
Copper + NAC
NAC may chelate copper at high doses; monitor copper status with long-term high-dose NAC use.
NAC + Vitamin C
Vitamin C regenerates oxidised glutathione back to its active form, amplifying NAC's antioxidant effect.
