The syrup is a dietary supplement containing Zinc and Vitamin C. Zinc and Vitamin C both contribute to the normal function of children's and adult's immune systems and they also contribute to the protection of their cell constituents from oxidative damage.
Children can be reluctant to take zinc supplements - due to the astringent taste - therefore lmunorm is formulated using Wallace's Glycinex system* which largely eliminates the taste. Adults also will appreciate its palatability.
