Treatment
N-Acetyl Cysteine (NAC)
Antioxidant precursor for lung and liver protection
Overview
In plain language
NAC replenishes glutathione levels and supports lung, liver, and immune health through powerful antioxidant effects.
A derivative of the amino acid cysteine, NAC is vital for producing glutathione — the body’s master antioxidant. It aids respiratory mucus clearance, protects liver tissue, and boosts immune defense. Seniors benefit from enhanced detoxification and resilience to oxidative stress.
