Clinical outcomes of conjugated linoleic acid supplementation in the overweight and the obese: a study protocol

Abstract

This is the protocol of a study aiming to assess the impact of conjugated linoleic acid (CLA) on body mass and composition, carbohydrate and fat digestion and absorption, total energy expenditure, lipid profile, polyunsaturated fatty acids levels, markers of endothelial dysfunction and mineral status in humans. Seventy-four adult volunteers (BMI ? 25 kg/m2) will be randomized to receive 3.0 g of 80% CLA (50:50 cis-9, trans-11 and trans-10, cis-12 isomers) or 3.0 g of linoleic acid daily for 3 months. A range of parameters will be measured at baseline and after the intervention.
