Ingredients
Quercetin (from Sophora Japonica Flower Extract)
Quercetin is a polyphenol with powerful antioxidant properties found naturally in plants like onions, green tea, apples, and berries.* It may support a strong immune system as well as heart and brain health.* When quercetin and vitamin C are used together, they may improve the bioavailability of one another for immune-supportive benefits.*
