Abstract:
This review highlights the importance of reporting adverse effects from food supplements to the Danish Veterinary and Food Administration (DVFA). Food supplements are not legally marketed in Denmark before notification to the DVFA, which does not assess their safety. If a food supplement is suspected of causing an adverse effect, the effect can be reported to the DVFA on its webpage. This review describes that the adverse effects may be due to high doses of ingredients, the use of ingredients with limited toxicological data, ingredient interactions, including the addition of substances that increase the bioavailability, interactions with a patient's medication, or adulteration.
