Supplementation of omega-3 fatty acids is considered valuable. Researchers analyzed 20 supplements sold in France for their fatty acid, triglyceride, and tocol content, as well as oxidative status. Results showed that only 2.5% of the supplements did not meet their omega-3 content claims. The tested products complied with established values for peroxide, p-anisidine, and Totox, indicating they were not oxidized.
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.
