N-acetylcysteine is part of preparations that are commonly available as dietary supplements in some countries. However, the bad news for the manufacturers or distributors of these dietary supplements is that in the Czech Republic, such products are considered medicines. According to current legislation, this ingredient is not allowed to be used in the manufacture of food supplements. Such a product can be detected not only during inspections by the Czech Agriculture and Food Inspection Authority (SZPI), but also during inspections by the State Institute for Drug Control (SÚKL), and information about this is then published on the website. So pay attention to the ingredients and avoid any complications.
