Selected polyphenolic compounds and their use as a supportive therapy in metabolic syndrome

Metabolic syndrome is diagnosed mainly in people of economically developed parts of the world and it affects 20-25% of the adult population worldwide. Nowadays, it is also more frequently diagnosed in children and adolescents. In addition to standard treatment that often involves polypharmacotherapy, and thus increases risk of side effects caused by drugdrug interactions, it is appropriate to look for alternative tools to support the treatment of metabolic syndrome components. Natural polyphenolic compounds, usually present in the so-called functional foods, are suitable candidates for that matter, due to the bioactivity and beneficial effects on the human body. Quercetin, troxerutin, diosmin, hesperidin or silybin are among the currently studied and used natural polyphenolic compounds with a positive effect on aspects of the metabolic syndrome. In addition to their antioxidant and anti-inflammatory effects, these compounds have other positive properties that very often outweigh their side effects whilst their usage in the pharmacotherapy.
