NAC (N-Acetyl-L-Cystein) is an amino acid with powerful antioxidant properties. NAC increases the amount of a substance called glutathione in the body and is widely recommended by practitioners. This helps reduce inflammation and promote immune system health.

NAC is used for :

  • CFS ( Chronic fatigue syndrome) relief
  • Brain fog relief
  • Promote immune system health
  • Long Covid Symptom relief
  • Energy level increase


A multicenter, randomized, double-blind trial with 262 participants indicated that taking a N-Acetyl-Cysteine supplement like this Source Naturals formula for 6 months supports upper-respiratory-tract and immune-system health. An additional analysis of 8 double-blind, placebo-controlled trials provides additional support for its favor for your respiratory health.

Recommended by top CFS specialists.
