Study Claims Type of Omega-3 Makes No Difference To Bioavailability
Bioavailability refers to how much of a supplement’s contents actually enter circulation after being introduced to the body. There has been debate recently about whether or not the different forms of omega-3s have different bioavailability. A recent two-part study suggests that no significant differences in bioavailability exist between EPA and DHA omega-3 fatty acids.
Participants in the first part of the study included nine healthy men who consumed test meals containing 1.1 grams of EPA plus 0.37 grams of DHA as either unmodified fish oil triglycerides, re-esterified triglycerides, free fatty acids, or ethyl esters. Participants in the second study included both men and women. For both studies, the participants consumed one supplement type for 12 weeks.
At the conclusion of the studies, the researchers found that both EPA and DHA were incorporated into the blood stream before plasma triglycerides and non-esterified fatty-acids both during the postprandial period and over the 12 weeks of supplementation. There was limited difference in the incorporation of EPA and DHA into blood lipids. In addition, there was no difference in incorporation between men and women.
Researchers from the University of Southampton conducted the study. It was published in the September 2016 issue of the British Journal of Nutrition.
Omega-3s have been linked to a number of health benefits, including improved mood, improved joint mobility, reducing the risk of age related macular degeneration, and aiding your immune system.
Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in omega-3s. For people who don’t like fish, consider taking a daily high quality non-fish supplement that has been tested for purity and potency.
