DSM’s new study finds similar bioavailability of fish- and krill- derived omega-3 supplements
The randomized, double-blind study monitored 66 healthy adults over a four week period and compared fish oil ethyl ester (EE), fish oil triglyceride (TG) and phospholipid (krill) forms with the same dose and concentrations of EPA and DHA. EPA and DHA are the two fatty acids best recognized for delivering health benefits, such as heart, brain and eye health. The study demonstrated that there was no statistically significant difference in total plasma and red blood cell EPA plus DHA levels observed between fish oil EE, fish oil TG and krill oil (at daily intake of 1.3g).
“It has previously been suggested that krill oil has greater bioavailability than fish or algal oil, but the studies referenced to make such claims had critical design flaws,” comments Karin Yurko-Mauro, PhD, Director, Clinical Research, Nutritional Lipids, DSM. “This new study was designed to objectively determine if there are significant differences in the bioavailability of different forms of omega-3s dose for dose, in order provide more evidence and give a clear message to consumers”.
“Omega-3s are scientifically proven to show positive health benefits for the heart, brain and vision, however the majority of populations across the world do not have adequate intake to maintain optimal health,” adds Norman Salem, Jr. Corporate Scientist, Nutritional Lipids, DSM. “It is critical that the industry continues to educate consumers on the essentiality of omega-3s and the equivalence of different forms that are available to them.”
DSM is committed to investing in clinical research to further understand omega-3s as part of its ongoing investment in being the world’s leading supplier of both marine and unique vegetarian based omega-3 ingredient solutions. DSM’s expanding portfolio of nutritional lipids includes life’sDHA™, a vegetarian form of DHA derived purely from a sustainable algal source, life’sOMEGA™ 60, the first high potency vegetarian DHA/EPA product available, and a wide range of MEG-3® omega-3 EPA/DHA products from fish oil including neutralized products that have no fishy taste or smell.
