How It Works
How It Works
NAC provides your cells with the building blocks to produce glutathione, a sulfur-containing compound that neutralizes free radicals and supports cellular health. Unlike direct glutathione supplements, NAC actually helps your body make its own glutathione where it's needed most.
Who It's For
Adults seeking serious antioxidant support, especially those exposed to environmental stressors or wanting to support their body's natural detoxification processes. Athletes and active individuals who want to support recovery from oxidative stress.
Who It's Not For
Not suitable if you're allergic to sulfur-containing compounds or taking certain blood thinning medications without professional guidance.
About This Product
What It Does
NOW NAC Extra Strength delivers 1000mg of stable N-Acetyl Cysteine to support your body's glutathione production. This sulfur-containing amino acid acts as a precursor to glutathione — often called the body's master antioxidant because it works inside cells where other antioxidants can't reach.
Why It Works
- GLUTATHIONE SUPPORT: Unlike unstable L-Cysteine, NAC provides a steady supply of building blocks for glutathione synthesis in liver and lung cells.
- CELLULAR PROTECTION: Helps maintain the protein structures that keep your cells functioning optimally under daily stress.
- CONVENIENT DOSING: One 1000mg tablet daily versus multiple smaller doses — no compromise on effectiveness.

Each tablet contains 1000mg of pure N-Acetyl-L-Cysteine with minimal excipients for maximum bioavailability. Simple tablet coating protects stability without unnecessary additives.
