When cold and flu season hits, many turn to supplements for extra protection. And while nothing replaces rest and good hygiene, targeted support can strengthen your immune defense.

Popular choices include vitamin C, zinc, elderberry, echinacea, and vitamin D. These ingredients help reduce the duration and severity of symptoms when taken at the first sign of illness—or preventively during outbreaks.

Some people also add probiotics to support gut-immune connection, or adaptogens like astragalus to maintain energy under stress.

Stick to products that offer clinically backed dosages, and avoid blends with unnecessary fillers or sugars.
