Krill oil has many positive health effects since it is rich in omega-3, phospholipids and astaxanthin. In recent years, as a result of rapid population growth and industrialization, the toxic heavy metal levels have increased especially in aquatic environments. Therefore, it is also possible to take up heavy metals to the human body through food supplements such as krill oil. This study aims to determine the fatty acid composition and the amounts of lead, mercury and cadmium in five different krill oil capsules. A total of 35 fatty acids were analysed. It was determined that the five different krill oil capsules met a proportion of daily recommended omega-3 fatty acid (EPA + DHA) and omega-6 fatty acid intake. Mercury levels were <0.2 µg/kg, cadmium levels <3 µg/kg and lead levels <3 µg/kg in all samples. It was observed that the heavy metal amount was below the limits specified by the Turkish Food Codex Contaminants Regulation. Based on the evaluation of the data obtained from our study, reliable krill oil capsules may be recommended for those who consume less than the recommended daily intake of omega-3 fatty acids, and for the vegetarians.
