NAC and Vitamin C
Vitamin C regenerates oxidised glutathione back to its active form, amplifying NAC's antioxidant effect.
NAC
A powerful antioxidant precursor and lung-health support compound.
Vitamin C
Antioxidant vitamin and iron-absorption amplifier.
Great to combine
These two are frequently stacked together; they complement each other and are commonly taken at the same time.
How to take them
NAC
- Dose
- 600–1,800 mg per day in divided doses
- Timing
- With food to reduce GI upset
Vitamin C
- Dose
- 200–1,000 mg per day
- Timing
- With iron-rich meals to maximize iron uptake
Frequently asked
Can you take NAC and Vitamin C together?
Yes, they are commonly taken together. Vitamin C regenerates oxidised glutathione back to its active form, amplifying NAC's antioxidant effect.
What's the best time to take NAC and Vitamin C?
Around the same time works well. NAC: With food to reduce GI upset. Vitamin C: With iron-rich meals to maximize iron uptake.
How do NAC and Vitamin C interact?
Synergy: Work better together than alone. Vitamin C regenerates oxidised glutathione back to its active form, amplifying NAC's antioxidant effect.
Related pairings
Glycine + NAC
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 + Zinc
NAC's chelating action can reduce zinc levels with high chronic doses; supplementing zinc alongside long-term NAC use is advisable.
Magnesium + NAC
Magnesium supports glutathione enzyme activity alongside NAC.
