Overview

Source Naturals Activated Quercetin is a dietary supplement built around a bioflavonoid complex for seasonal comfort and immune support. Each serving delivers 1,000 mg of quercetin, paired with vitamin C, magnesium citrate, and bromelain to complement the formula. The product is suitable for vegetarians.

The formula is designed to provide more than quercetin alone. In addition to the primary bioflavonoid, it includes ingredients commonly used to support immune function, respiratory health, antioxidant activity, and the body’s normal inflammatory response. According to the source, preliminary studies have associated quercetin with helping inhibit histamine release and supporting a healthy immune and inflammatory response.

This supplement comes in tablet form and uses a divided-dose schedule rather than a once-daily serving. That approach, along with the inclusion of bromelain, vitamin C, and magnesium, makes it a more elaborate quercetin formula than a basic standalone version.
