Elderberry, rosehip and blackcurrants are all exceptionally rich sources of important compounds called flavonoids, including anthocyanidins that are known potent antioxidants. These compounds are believed to support the immune system by maximising the patient's antioxidant defence against free radicals.The flavonoid family found in these three fruits is uniquely positioned for such a task, since they are physiologically active in both lipid and aqueous environments in the body, which makes its overall antioxidant properties many times that of vitamin C or vitamin E. Many studies spanning decades of research consistently and repeatedly show that maintaining a high antioxidant defence system lowers a person's risk of disease as well as stimulating the immune system.Imuno-Strength® is a tasty natural blend of elderberry, rosehip, red grape and blackcurrant concentrates carefully formulated to retain the nutritive properties of the fruits. Recommend to those 5 years and upwards whose immune system is under pressure and requires a boost.
