Research indicates that supplemental Vitamin C can reduce the duration and severity of the common cold and your susceptibility to it. Why? Vitamin C boosts your immune system so your body battles illness more effectively. Jamieson Vitamins C & D – Chewable Morello Cherry is the first Vitamin C formula to be enriched with Vitamin D3, the same disease-fighting form produced when your skin is exposed to sunlight. Combined, they protect you – even during the winter months when sunshine is limited. This innovative product is a great choice for anyone who regularly takes Vitamin C, but wants additional protection from Vitamin D. Formulated from fresh, pure and active natural sources, Vitamins C & D – Chewable Morello Cherry is sweetened with sucralose, which doesn€™t harm tooth enamel. Directions : For adults.
