Different superscript letters indicate significant statistical differences, Mann–Whitney p < 0.01, n = 8–9. Omega-3 Index is calculated from (n-3 HUFA × 0.32) − 3.5 [28, 59]). Tissue levels of n-6 HUFA is in good concurrency with estimated n-6 HUFA values in Table 1

LNA linoleic acid, SFA saturated fatty acids, MUFA monounsaturated fatty acids, HUFA highly unsaturated fatty acids
