Elderberries are berries native to Europe and the Americas and contain high levels of vitamin C, fiber, flavonoids, anthocyanins, and phenolic acids – powerful antioxidant compounds. These components help strengthen immunity, support the treatment of colds and flu, improve cardiovascular health, protect the skin from UV rays, reduce inflammation, provide antibacterial effects, and slow aging. In particular, the anthocyanins in elderberries have antioxidant activity 3.5 times stronger than vitamin E.
