Elderberry and zinc have each been individually studied for their potential roles in immune support, and their combination in lozenges and supplements has gained popularity as a cold-season staple. Research suggests that elderberry extracts may help reduce the duration and severity of upper respiratory symptoms, possibly due to their rich flavonoid content and influence on immune cell signaling. Studies indicate that zinc, particularly when taken as a lozenge at the onset of symptoms, may also shorten the duration of common colds and help ease sore throat discomfort. While the two ingredients are often paired based on their complementary mechanisms, more research on the specific combination is needed to fully understand how they work together to support immune function during times of seasonal challenge.
