The majority of the population does not reach the recommended intake of polyunsaturated ω-3 fatty acids (ω- 3 PUFA) in the diet, which contributes to the deficiency of ω-3 PUFA in the body with adverse health effects. The omega-3 index (O3i) is a parameter that measures the proportion of ω-3 fatty acids, specifically eicosapentaenoic (EPA), docosahexaenoic (DHA) and docosapentaenoic acid (DPA) in the total amount of fatty acids in the membranes of erythrocytes (red blood cells), with O3i ≥8% being associated with a lower risk of chronic diseases, especially cardiovascular diseases. Due to their insufficient intake in the diet, nutritional supplements containing these fatty acids are often recommended. However, the quality of commonly available supplements can be a problem. This article summarizes information on methods for monitoring sufficient ω-3 FA intake and options for assessing the quality of nutritional supplements containing ω-3 FA available on the Czech market.
