There are many types of elderberries available, including black, blue, and red, but the black elderberry (Sambucus nigra) is the premier variety for boosting immune health. Black elderberries have a high concentration of beneficial flavonoids, called anthocyanins. Anthocyanins give the berry its deep color and are recognized as powerful antioxidants that support healthy immune function. Elderberries have some of the highest concentrations of anthocyanins, compared to other berries. The addition of vitamin C and zinc make this unique blend one of the best immune protection formulas that nature has to offer. Keep the family healthy all year round with Black Elderberry Gummies.
