1. What is V-C and what is it used for

  • V-C is an effervescent powder containing vitamin C, which participates in oxidation and reduction processes in cells, e.g., in cellular respiration. It is involved in amino acid metabolism, the synthesis of steroid hormones in the adrenal cortex, and insulin synthesis. It is essential for the production of collagen and intercellular substances in many tissues (skin, bones, teeth, cartilage, tendons, vascular endothelium). Increased demand for vitamin C occurs in the following cases: AIDS, alcoholism, gastrointestinal diseases (e.g., prolonged diarrhea - associated loss of ascorbic acid, achlorhydria - reduced absorption, resection of the ileum), prolonged exposure to low temperatures, prolonged fever, chronic hemodialysis, certain infectious diseases (pneumonia, tonsillitis) and recovery period, prolonged stress, wound healing and bone fractures, hyperthyroidism, burns, smoking, cancer, surgical procedures.

Indications for use of the medicine are:

  • states of vitamin C deficiency (e.g., inflammatory conditions of mucous membranes, scurvy);
  • states of increased demand for vitamin C (e.g., colds, recurrent infections of the upper respiratory tract, reduced immunity, convalescence).

2. Important information before using V-C

When not to use V-C

  • increases iron absorption from the gastrointestinal tract. If it is necessary to take doses above 1 g per day, the patient should inform their doctor about all medicines they are currently taking, as vitamin C may affect their action. In higher doses, the use of vitamin C may falsify the results of blood, urine, and stool tests, so if such tests are necessary, the patient should inform their doctor about the use of the medicine
