Low dose omega-3 supplements show (minor) benefits in overweight people

Daily supplements of omega-3 fatty acids increased levels of a hormone linked to diabetes, but had no effect on inflammation in overweight people, says a new study from Denmark.

Researchers from Aarhus University Hospital report that a daily dose of 1.1 grams of omega-3s resulted in a significant decrease in levels of adiponectin, a hormone released from fat cells that plays an important role in the regulation of insulin sensitivity and energy, after 6 weeks of supplementation, but had no “overall anti-inflammatory effect”.

The study involved 50 overweight people taking the 2 grams per day of fish oil or olive oil (control), and the results are published in Nutrition Research​.

“Our study hypothesis was only partly verified, as there was an expected (albeit small) effect on adiponectin levels but no overall anti-inflammatory effect of supplementation with a low dose of marine omega-3 PUFA,”​ wrote the researchers.

“Further studies are, therefore, needed to study effects on inflammatory markers and to establish the optimal dose of marine omega-3 PUFA in overweight subjects.”
