Vitamin C is a water-soluble vitamin and serves as an antioxidant, protecting cells against damage caused by free radicals. In addition, vitamin C is essential for synthesis of collagen, which is a constituent of connective tissues, cartilage and bones. Healthy animals can normally synthesize sufficient amounts of vitamin C. However, due to stress, caused by for instance, vaccination, transportation, heat or cold stress, the animal might not be able to synthesize enough vitamin C to meet its requirements. In these situations, supplementation of vitamin C by administration of Introvit-C-200 Oral is the solution to correct vitamin C deficiency, especially during stress and helps the animal to overcome stressful circumstances.
