The benefits of NAC for daily wellbeing
What is NAC?
N-acetyl cysteine, or NAC, is a stable form of the amino acid cysteine. It has long been used in clinical settings to support detoxification, especially in cases of overdose or toxicity. But its benefits go far beyond emergency medicine. NAC is now recognised for its daily role in supporting antioxidant activity, cellular defence and overall resilience - making it an ideal ingredient for everyday wellbeing.
How NAC benefits us
At City Survivor, our focus is on wellbeing in the modern environment. Urban living exposes us to a daily mix of pollutants, stressors and lifestyle factors that increase oxidative stress. That’s where NAC comes in.
- Antioxidant support: NAC can work directly as an antioxidant, but even more usefully it provides the cysteine required to produce glutathione - your body’s master antioxidant. More glutathione means better cellular defence against free radical damage.
- Anti-inflammatory protection: NAC reduces levels of proinflammatory cytokines.
- Everyday resilience: Whether you’re exposed to traffic fumes, lack of sleep or a demanding schedule, NAC supports your body’s ability to recover and rebalance.
Why use NAC rather than L-Cysteine or Glutathione?
We don't use free L-cysteine as a supplement because it's highly unstable. Glutathione is also ineffective as a supplement. In contrast, NAC is a stable and non-toxic supplement which is highly effective at increasing the levels of L-Cysteine, and in turn Glutathione, in the body.
A smart ingredient for modern life
You won’t always see or feel oxidative stress - but it’s happening every day. Including NAC in our Pollution Protection Multivitamin reflects City Survivor's ethos of proactive, intelligent supplementation. It’s not about fixing what’s broken; it’s about giving your body the tools to stay balanced in the first place.
Final thought
Supplementing should do exactly that - supplement a good diet, not replace it. At City Survivor, we focus on ingredients that provide genuine, foundational support rather than fleeting trends. NAC is a perfect example. It's not new or trending, but it's a reliable way to top up one of the body's most important antioxidants. Used consistently, it supports your resilience and overall wellbeing - helping you stay ahead of the demands of modern life.
