Washington: A new study has found that widely-used fish oil supplements modestly increase amounts of a hormone that is associated with lower risk of diabetes and heart disease.Fish oil supplements, also called omega 3 fatty acid capsules, raise levels of adiponectin in the bloodstream. Adiponectin is an important hormone that has beneficial effects on metabolic processes like glucose regulation and the modulation of inflammation. In long-term human studies, higher levels of adiponectin are associated with lower risks of type 2 diabetes and coronary heart disease."While prior animal studies found fish oil increased circulating adiponectin, whether similar effects apply in humans is not established," said the study`s lead author, Jason Wu, PhD, of the Harvard School of Public Health."By reviewing evidence from existing randomized clinical trials, we found that fish oil supplementation caused modest increases in adiponectin in the blood of humans," Wu stated.The meta-analysis reviewed and analyzed results from 14 randomized, placebo-controlled clinical trials. In total, 682 subjects were treated with fish oil, and 641 were given placebos - most commonly olive and sunflower oils. In those taking fish oil, adiponectin levels increased by 0.37 ug/mL.
