The number of people who buy food supplements online for a healthy and balanced diet is substantial. Experts warn consumers about buying food supplements only from pharmacies.
Supplements that are bought without a prescription and seem innocent cause serious health problems when not taken in certain doses. Also, just because it's plant-based doesn't mean it's harmless. Fish oils, the most common among them, can cause various cancers due to heavy metal consumption in their content, especially when produced in uncertified or illegal ways. For these reasons, food supplements must be bought from pharmacies, as stated by control mechanisms such as the Turkish Medicines Agency.
