How It Works
How It Works
N-Acetyl-L-Cysteine is a free form amino acid your body uses to produce glutathione, the master antioxidant involved in fighting oxidative stress, maintaining immune function, and repairing tissues. Unlike regular L-cysteine, the acetylated form is more stable and bioavailable.
Who It's For
Adults looking for serious antioxidant support, especially those over 65 wanting to reduce flu-like symptoms. Ideal for people exposed to oxidative stress from training, environmental factors, or aging.
Who It's Not For
Not suitable for children or those with active stomach ulcers. Consult your healthcare practitioner if pregnant or nursing.
