NUTRILITE Triple Guard Echinacea is an immune-boosting supplement made from echinacea (purple coneflower and angustifolia). Our formula blends 3 extracts from 2 forms of the plant - 2 from the root, 1 from the leaf. Combining both forms gives the broadest boost to your body's natural defenses. We use organic-certified echinacea, guaranteed for purity and potency, and standardize all extract levels.
