Quercetin 20x plus

Cold and flu season is approaching fast! We offer a selection of supplements tailored to address viral, allergy, and sinus issues.

One standout option is Quercetin 20× Plus Quercetin Phytosome−Antioxidant Complex by Xymogen.
Quercetin is a flavonoid found in medicinal plants and various foods like onions, apples, berries, brassica vegetables, nuts, wine, and black tea. This particular form of Quercetin is more bioavailable than others, meaning your body can absorb it more effectively.

Research indicates that Quercetin can block histamine release, reduce eosinophil recruitment, and inhibit pro-inflammatory cytokine activity. A study from Japan found that Quercetin significantly improved sleep and reduced allergy symptoms, such as sneezing, itchy eyes, and a runny nose, compared to a placebo. Additionally, another study showed that Quercetin, when used alongside standard care early in the respiratory process, led to better infection clearance, improved acute symptoms, reduced illness progression, and lower blood inflammatory markers.

N-Acetyl Cysteine (NAC) is an essential building block to glutathione, a potent antioxidant that shields the body from free radicals, which can contribute to aging and serious health conditions such as cancer and heart disease. Taking NAC supplements can restore antioxidant levels, especially when your immune system is weakened, thereby improving your recovery. Additionally, NAC acts as a natural mucolytic agent, aiding in mucus clearance from the airways similar to Mucinex. It helps reduce oxidative stress in the lungs, increases glutathione levels, lowers inflammation, and diminishes airway sensitivity.
