According to the card, the food supplement contains ascorbic acid and rutoside (rutin): 50 mg of each in one tablet; it is intended for an additional intake of vitamins C and P in the daily diet. The short description says that it makes up for a deficiency of vitamins, reduces the permeability and fragility of capillaries and has antioxidant properties – the card gives no confirmation of this. Why exactly such a combination, and whether the substances can be taken separately, it does not explain.
General information (not a manufacturer's instruction): the total dose of vitamin C from other sources is worth taking into account.
