About this item
Product details
Breathe easy with swanson ultimate respiratory defense with nac & quercetin! This novel formulation combines two potent antioxidants in one convenient veggie cap to support healthy lungs and immune system function no matter what the season brings. N-acetyl cysteine (nac) is an amino acid derivative that has been clinically studied to support respiratory health and also helps replenish levels of glutathione, often called the "master antioxidant. " nac and glutathione work together to protect against oxidative stress from free radicals and maintain healthy liver function, thereby supporting detoxification pathways. Nac is gaining popularity for promoting healthy aging and immune health. Quercetin is an abundant antioxidant found in plants like berries and leafy greens that acts as a free radical scavenger to support healthy aging. It is an important part of our body's immune response due to its interaction with cell signaling. While most of us get the quercetin we need through everyday foods like onions, apples and berries, research suggests higher amounts of this unique bioflavonoid help to support respiratory tract health. Swanson ultimate respiratory defense provides a concentrated dose of this powerful antioxidant for optimum protection. Swanson ultimate respiratory defense delivers 600 mg nac and 250 mg quercetin in a single veggie cap serving for advanced support of healthy respiratory and immune function.
- Supports healthy respiratory function and cellular antioxidant activity
