Swanson Ultimate Respiratory Defense

Support the respiratory tract with Swanson Ultimate Respiratory Defense with NAC & Quercetin!

Key ingredient

  • N-Acetyl Cysteine (NAC) - is an amino acid derivative that has been clinically studied to support *respiratory health and also helps to replenish glutathione, often called the “master antioxidant”. NAC and glutathione work together to protect against oxidative stress from free radicals and maintain healthy liver function, supporting detoxification pathways.
  • Quercetin - is an abundant antioxidant found in plants such as berries and leafy greens that acts as a free radical scavenger to support healthy aging.

As a dietary supplement, take one veggie capsule per day with water or as recommended by your healthcare provider.
