Sambucol is a unique black elderberry extract rich in immune supporting flavonoids. Flavonoids are powerful, natural antioxidants that are thought to work to protect the body’s cells from the potential damage caused by free radicals. Sambucol is a delicious tonic made from black elderberries (Sambucus nigra) and has the equivalent of up to 1000 in every 120ml bottle. The black elderberries in Sambucol have twice the natural antioxidant capacity of blueberries and more than 50% the overall antioxidant capability of cranberries. Antioxidants support the system by helping to neutralise the harmful effect of free radicals.
