Supplements (also called nutraceuticals because they derive from natural substances) and functional foods are now readily available and usable by the general population. The term nutraceutical derives from a fusion of the terms nutritional and pharmaceutical y was used for the first time in 1989 by Stephen De Felice, President of the Fundación para la Innovación en Medicine (Cranford, NJ, EE. UU. ). On the other hand, functional foods have additional effects due to the presence of components, generally non-nutritious, which interact selectively with one or more physiological functions of the organism (biomodulation) in such a way that an improvement in the state of health and well-being is evident. And/or a reduced risk of disease.~The Regulation EC / 178/2002 of the Parliament and the Council, 28/01/2002 establishes the general principles and requirements of food law, shows the European Food Safety Authority (EFSA), and establishes the procedures in the field of food safety.~Given their documented efficacy following the European Claims, which indicate for each substance what the individual uses may be (EFSA Journal 2011; 9 (4): 1984; EFSA Journal 2011; 9 (4): 2061; EFSA Journal 2012 ; 10 (3): 2604; EFSA Journal 2012; 10 (5): 2702; EFSA Journal 2016; 14 (1): 4367; EFSA Journal 2017; 15 (1): 4680; EFSA Journal 2018; 16 (1): 5136), a doubt related to safety in the general population remains today.~For this reason, in the month of March 2018, the Health and Quality of Life Working Group of the Italian Federation of Life Sciences (Fisv), which also includes the Italian Society of Pharmacology (Sif), the Italian Anthropological Association (Aai), Italian Agricultural Chemistry (Sica), Italian Society of Environmental Mutagenesis (Sima), Italian Society of General Microbiology and Microbial Biotechnology (Simgbm) and Italian Society of Plant Pathology (Sipav) has re-evaluated the scientific bibliography on the use of supplements or supplements food and has assessed that in the vast majority of cases their use is not only improper - as a good diet would be much more efficient to heal any deficiencies in trace elements or vitamins - but that often these products can cause undesirable effects, both for the concomitance of pathologies or pharmacological treatments with which they can interfere, both for the potential toxicity and oligopoly Minds and vitamins can exert on the body if their level of intake is higher than the needs of the moment. This is because many if not all of these supplements are authorized without having objective clinical safety data. Many of these are also used in poly-treated patients where interactions or adverse events may develop that are underestimated or unrecognized.~In consideration of the fact that the nutraceutical market is constantly growing (it is estimated 90 thousand products for over 30 billion dollars in turnover only in the US and 3 in Italy.), The need arises to evaluate real life in a manner objective to the possible efficacy and safety of nutraceuticals and functional foods used to treat systemic or local diseases.
Supplements and functional foods are now readily available and usable by the general population. Many supplemnets are commonly used in poly-treated patients where interactions or adverse events may develop, therefore we evaluate in the rela life the use of nutraceuticals, their clinical effects and the development of adverse drug reactions
