Extra C Plus Zinc combines zinc with bioflavonoids and high-strength, preferred forms of vitamin C for common cold symptoms. Vitamin C and zinc are key nutrients for a strong and healthy immune system, while bioflavonoids are found naturally in citrus fruits. These preferred forms of vitamin C are gentler on the stomach and teeth. They are made in Australia, and are suitable for adults, including women and men. The product is vegetarian and vegan friendly. For immune support, take 1 tablet daily with food. To reduce the severity and duration of a cold, take 2 tablets twice daily with food. Vitamin and mineral supplements should not replace a balanced diet. If symptoms persist, consult your healthcare professional. Do not use if the cap and/or bottle seals are missing.
