Elderberry is a small dark purple berry that has been used for centuries in traditional herbalism as an aid to the immune system. In our Immune Charge+® formula, we use Haschberg variety European black elderberry, known for its high potency in anthocyanin flavonoids. Elderberry has powerful, direct effects on microbial balancing and management supporting a healthy immune response.* ​ ​In addition to zinc and vitamins A, C, D, E, and K, elderberry is a key ingredient in our Immune Charge+® formula.
