What Is NAC? The Science-Backed Antioxidant Your Body Needs

In a world full of trendy wellness ingredients, few compounds are as clinically backed, widely studied, and under appreciated as N-Acetyl-L-Cysteine (NAC). At Arcwell, we’ve made NAC the star of our newest release — a clean, filler-free powder designed for optimal absorption and flexible dosing.

What Is N-Acetyl-L-Cysteine (NAC)?

NAC is a stable form of L-cysteine, an amino acid your body uses to produce glutathione — often called the “master antioxidant.”

• Fighting oxidative stress and inflammation
• Supporting immune and respiratory health
• Detoxifying the liver and lungs
• Protecting your DNA and slowing cellular aging
  

Without enough cysteine, your glutathione levels fall — leaving your body more vulnerable to toxins, inflammation, and oxidative damage.

Top 5 Benefits of NAC (Clinically Studied)

1. Boosts Glutathione & Reduces Oxidative Stress

NAC raises intracellular glutathione levels, which:

• Supports mitochondrial health
• Slows signs of aging
• Enhances detoxification

Clinical trials confirm NAC improves antioxidant markers and reduces inflammation, even in healthy aging populations.

2. Supports Lung & Respiratory Function

NAC is a natural mucolytic — it helps thin mucus and improve breathing.

Research shows it:

• Reduces symptoms of chronic bronchitis and COPD
• Eases flu-like respiratory inflammation
• Improves lung function in cystic fibrosis

3. Liver Detox & Protection

Used in hospitals for acetaminophen overdose, NAC is incredibly effective at protecting the liver.

Daily supplementation supports:

• Glutathione production in liver cells
• Lower liver enzymes in NAFLD patients
• Protection from alcohol and toxin exposure

4. May Support Hair Regrowth

Emerging studies show that oxidative stress and inflammation can weaken hair follicles.

NAC may help:

• Reduce shedding caused by inflammation
• Support regrowth in cases like trichotillomania
• Improve scalp environment

5. Cognitive & Immune Support with Aging

NAC has shown promise in:

• Protecting brain cells from oxidative damage
• Enhancing immune resilience in older adults
• Supporting mental clarity and mitochondrial energy

Backed by 2025 Clinical Trials

Recent human trials confirm N-Acetyl-L-Cysteine (NAC) supports:

• Reducing nerve pain in diabetic neuropathy¹
• Improving liver enzymes in Non-alcoholic steatohepatitis (NASH) patients²
• Enhancing immune response in aging adults³
• Assisting hair regrowth via oxidative stress reduction⁴
