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, p-anisidine value, and Totox values established by the Global Organization for EPA
and DHA Omega-3s (GOED) and were not oxidized.
