27 maggio 2015 aggiornato da: Clinica Universidad de Navarra, Universidad de Navarra
Cellular and Molecular Effects of Lipoic Acid and Eicosapentaenoic Acid (EPA) on Adipose Tissue: Potential Application in Human Obesity
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.
