Natural Factors Quercetin 500Mg 60Vcaps

When it comes to antioxidant support, quercetin alone is great. But quercetin combined with zinc and copper is even better.

The benefits of quercetin, a natural plant compound, are many. It protects cells from damaging free radicals, and helps regulate immune response. This formula amplifies the benefits of quercetin with zinc, which is crucial for immune support, and copper, which competes with zinc for absorption. Quercetin helps zinc enter cells, so it can better do its immune work. Copper helps maintain the optimal zinc/copper ratio needed for all-around health.
