Vitamin C is necessary for the good condition of the immune system, bones, teeth and gums, as well as to help regulate fat and cholesterol levels in the blood. The body's daily requirement for vitamin C is higher than for any other water-soluble vitamin. For optimal status, vitamin C should be taken in small amounts throughout the day and evening, because the body eliminates it quickly. This is not always possible, so sustained-release vitamin C tablets are an ideal alternative to meet this goal. Vitamin C 1,000 mg is presented in two-stage delayed-release tablets. Fifty percent of the product is released rapidly in the stomach (first stage). The rest of the vitamin C is released gradually in a second stage that can last more than 12 hours.
