Food supplements are foodstuffs intended to supplement the normal natural diet. They are concentrated sources of nutrients. They are not medicinal products, they are not intended for treatment and that is why in their case it is misleading, deceptive and at the same time forbidden to state any information about prevention, treatment and healing. Food supplements must not contain ingredients in quantities which are present in medicinal products, they must not contain narcotic, psychotropic substances and any other components, which are not safe, or in quantities which are not proved as safe. In case they contain “novel food” ingredients, these must comply with the Regulation (EC) No. 2015/2283.
