What the brand says

Elderberry contains several compounds that help support healthy immune function. Elderberry contains anthocyanins, a class of phytochemicals that support immune function by boosting the production of cytokines (proteins that regulate immune response). Stress plays a significant role in reducing immune function. Elderberry extract helps to reduce overall stress levels, and also significantly shortens recovery time from physical exertion. By reducing stress and its related effects, elderberry extract helps maintain a strong immune system.
