Salmon Oil May Help Lower Markers of Oxidative Stress

Oxidative stress is basically an imbalance between the production of free radicals and the ability of the body to counteract or detoxify their harmful effects through neutralization by antioxidants. A recent study suggests that supplements of salmon oil may help lower markers of oxidative stress.

Participants in the study included 160 healthy adults with an average age of 59.3. Over the course of 16 weeks they were given either a placebo, three grams of salmon oil plus a multivitamin, six grams of salmon oil plus a multivitamin, or 6 grams of salmon oil. The six-gram supplement contained 480 mg of EPA and 480 mg of DHA omega-3s.

At the conclusion of the study, the researchers noted significantly lower F2-isoprostane levels in both of the six gram groups. F2-isopropostanes are created when fats are peroxidized. They are considered to be the most reliable biomarkers of in vivo lipid peroxidative damage. The decreases in F2-isopropostane levels were also associated with higher PUFA           levels in the participant’s red blood cells.

There were no changes seen in the three-gram group and no significant difference between the two six gram groups. Additionally, there was no notable effect on inflammation seen in any of the groups.

Researchers from the Swinburne University of Technology in Australia conducted the study. It was published online ahead of print on November 21, 2014, in the Journal of Functional Foods.

Salmon oil has high levels of omega-3s. Omega-3s have been linked to a number of health benefits, including alleviating arthritis pain, improved mood, improved joint mobility, helping with 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 DHA and EPA omega-3s.
