Fig. 2. — Peroxide (a), anisidine (b) and total oxidation (TOTOX) (c) levels of over-the-counter n-3 PUFA nutritional supplements available in Canada grouped by product oil source. No error bars are presented for peroxide (a) and TOTOX (c) levels in krill products because mean values were derived from a single product. * Mean value was significantly different from that for plant-based oil source n-3 nutritional supplements (P < 0·05). The dotted lines represent the safety limits (peroxide, <5 mEq/kg; anisidine, <20; and TOTOX, <26) recommended by the Global Organization for EPA and DHA Omega-3s (GOED), the Council for Responsible Nutrition (CRN) and the International Fish Oil Standards (IFOS)⁽¹⁹^–²²⁾. Combo, combination.
