Tuna is a high-protein staple for many health-conscious individuals — but it comes with a hidden cost: mercury exposure. As much as we love its convenience and omega-3 content, repeated consumption of larger fish like tuna can gradually elevate mercury levels in the body. And mercury is no joke: it’s a neurotoxin linked to cognitive decline, fatigue, and mitochondrial dysfunction.
But there’s promising news — and it comes in the form of a smart supplement: N-Acetylcysteine (NAC).
🧠 What Is NAC and Why Should You Care?
NAC is a powerful antioxidant precursor to glutathione — the body’s master detoxifier. It's widely studied for its role in:
- Liver detoxification
- Reducing oxidative stress
- Improving mitochondrial function
- Supporting brain health and mood
- Enhancing immune response
But what’s especially intriguing is NAC’s potential to reduce mercury accumulation, as highlighted in multiple studies.
🔬 The Science: How NAC May Reduce Mercury Toxicity
-
Animal Studies Back It Up
A 2006 study published in Environmental Health Perspectives found that NAC could significantly reduce mercury levels in the liver and kidneys of rodents exposed to methylmercury — the toxic form found in fish【source: PMC1533084】. -
Fast-Acting Chelator
NAC appears to bind to mercury in the bloodstream before it gets absorbed into tissues, allowing it to be excreted more easily. -
New Research in Tuna Lovers
A 2020 study showed that co-administration of NAC with meals containing mercury-contaminated fish reduced blood mercury levels in humans【Tandfonline source】. This suggests a real-world application for frequent fish consumers. -
Synergy With Glycine
NAC paired with glycine (as in GlyNAC) shows even greater potential in supporting detox, reversing oxidative damage, and improving mitochondrial health — which declines with age and toxin exposure【ScienceAlert source】.
✅ Other Benefits of NAC Supplementation
- Supports lung function (used in hospitals for chronic bronchitis)
- May help stabilize blood sugar in insulin-resistant individuals
- Plays a role in psychiatric and neurological health
- Promotes healthy aging via glutathione replenishment
