Echinacea Extract may support the maintenance of a healthy immune system.* The extract is sourced from Echinacea purpurea (purple coneflower), a native North American plant historically used to boost the body's defense system.* Traditionally consumed during seasonal shifts, Echinacea is now frequently consumed as a dietary supplement. Our Echinacea Extract is available alone, or as part of Vital Nutrients' Immune Support and Herbal Biotic formulations.
