NCT01138774

Brief Summary

The aim of the study is to analyze the effects of Lipoic acid and/or EPA supplementation on weight loss, lipid profile, insulin resistance, oxidative and inflammation parameters, metabolomic profile as well as on adipose tissue gene profile in healthy overweight/obese subjects following an energy-restricted diet.
