13C-docosahexaenoic acid (DHA; upper panel), 13C-omega-3 PUFA (13C-alpha-linolenate + 13C-eicosapentaenoate + 13C-docosapentaenoate; middle panel) concentrations and ratio given as a percentage of 13C-omega-3 PUFA/13C-DHA (lower panel) in plasma total lipids of young (full symbols) and elderly (open symbols) over 28d after giving the 13C-DHA. Data are shown for n = 5 for the young and n = 6 for the elderly (*P < 0.05).
