Approved health claims for amino acids in/as food supplements

Abstract

Food supplements in the European Union (EU) were initially regulated by Directive 2002/46/EC, whereas in 2006, EU adopted the new Regulation on nutrition and health claims made on food – Regulation 1924/2006. Meanwhile, in the United States of America (USA), dietary supplement is defined by the congress of Dietary Supplement Health and Education Act (DSHEA, 1994). Food supplements can be beneficial to the health of consumers, but scientific reviews of the existing data should be made by competent authorities. In Europe, a scientific review is made by European Food and Safety Authority (EFSA), the Panel of Dietetic Products, Nutrition and Allergies (NDA Panel). Amino-acids have been the object of many scientific studies, with many of them showing their implication in health. Amino-acids carry out a big role in many body functions, cells structure, transport and storage of nutrition, leading us to the main aim of this article that is providing data related to amino-acids implication in health benefits, specifically health claims of Arginine (Erection, vascular system, muscle integrity and hematopoesis immune system function, spermatogenesis), Glutamine (intestinal health, supporting glycogen replenishment, increasing cell swelling, immune health, abundance in the body, muscle function), Lysine (cardiovascular system, increase metabolism, bones, body tissue, immune system function). Nevertheless, they don`t take their credit yet and are not properly recognized in medical sciences in Europe, since the health claims of food containing amino-acids are still considered to be not established in terms of cause and effect relationship.
