Thorne doses **N-Acetyl-L-Cysteine** at 500mg per capsule, with a label recommendation of two to three daily — putting you at 1,000–1,500mg, comfortably within the 600–1,800mg clinical range. At that intake, you're getting solid support for glutathione production, the antioxidant your liver relies on for detoxification and your cells use to defend against oxidative damage.
Beyond liver health, NAC has clinical backing for respiratory function and immune support. The capsule format gives you dosing flexibility — two capsules for maintenance, three to push toward the upper clinical range.
A single capsule at 500mg falls just short of the 600mg minimum studied dose. If you only take one daily, you're below the evidence threshold — the label's multi-capsule recommendation is where the clinical support actually begins.
