The purpose of this work was to study the quality and safety of some sports nutritionproducts. The objects of study were sports nutrition products: protein bars of ‘ProteinBar’(Russia) and ‘Bombbar’ (Russia); capsule forms of dietary supplements ω–3, ω–6, ω–9 firms‘Sportline’ (Russia), ‘Multipower’ (Germany) and ‘Maxler’ (USA). According to the researchresults, the normalized safety indicators of the fat component of the studied products for sportsnutrition (acid number and peroxide) are within acceptable values. The standardized safetyindicators of the fat component do not fully reflect the safety requirements for the fat componentof sports nutrition products, since there are no standards for the most important indicators of fatsafety – the content of secondary oxidation products – copolymers insoluble in petroleum etherand epoxides. The results obtained in the course of the work showed that in almost all of thestudied samples are content of epoxides (7.5–47.6 g-1) and secondary oxidation products – 1% ormore.
