Abstract

Supplementation of omega-3 fatty acids is considered a valuable strategy to supply the low intake of these fatty acids. Thus, the safety of the supplements is an important milestone. Because of that, we analyzed 20 unflavored supplements sold in the French market for fatty acid and triglyceride composition, for EPA and DHA, and for tocol content, as well as for oxidative status. This study found that only 2.5% of the supplements did not meet their label claims for omega-3 content. TAG analysis showed high variability among the triglyceride distribution, and the same trend was also noticed for the tocol content; in fact, a high variability of the distribution of the six tocols (four tocopherols and two tocotrienols) was found among the samples. Of the tested products, all of them complied with peroxide value, -anisidine value, and Totox values established by the Global Organization for EPA and DHA Omega-3s (GOED) and were not oxidized.

摘要

补充ω-3 脂肪酸被认为是一种有价值的策略，可以补充这些脂肪酸的低摄入量。因此，补充剂的安全性是一个重要的里程碑。为此，我们分析了在法国市场销售的 20 种无味补充剂的脂肪酸和甘油三酯组成、EPA 和 DHA 以及生育酚含量以及氧化状态。这项研究发现，只有 2.5%的补充剂不符合其标签上声称的ω-3 含量。TAG 分析显示，甘油三酯分布的变异性很高，生育酚含量也有同样的趋势；事实上，在样本中发现了六种生育酚（四种生育酚和两种生育三烯酚）分布的高度变异性。在所测试的产品中，所有产品均符合全球 EPA 和 DHA ω-3 组织（GOED）规定的过氧化物值、-茴香胺值和 Totox 值，且没有被氧化。
