Vitamin C is one of the vitamins where research suggests that optimum benefits lie in intake greater than 100% RDA; in particular, Vitamin C is beneficial to the immune system. As such, Vitamin C supplements usually provide amounts ranging from 60mg to 1000mg.
This product contains 500mg of Vitamin C in a slow-release form, which some nutritional experts believe results in better bioavailability. As such, the recommended dose of one tablet a day would be expected to deliver the benefits associated with a high intake of Vitamin C. The product is quite expensive.
