Sambucol Extra Strong is a food supplement in the form of capsules intended for adults over 18 years of age. Its recipe, which contains a standardized extract of elderberry, vitamin C and zinc, was composed in such a way as to support the functioning of the immune system. The preparation is especially recommended in periods that require additional support for the body's immunity, e.g. autumn and winter.

Elderberry has a beneficial effect on the good functioning of the immune system and on the health of the respiratory system. It has antioxidant properties - it contains natural antioxidants that help protect cells and tissues against free radicals. To make the preparation even more effective, it has been enriched with vitamin C and zinc, which, like elderberry, support the proper functioning of the immune system and help protect cells against oxidative stress.
