Obesity is significantly associated with inflammatory process and oxidative stress. Alpha lipoic acid (ALA) is a potent antioxidant that has been reported for reducing weight in animals and obese adults in several studies but no data are available in pediatrics. We investigated the possible beneficial role of ALA in obese children.


Eighty obese children and adolescents were randomized into two groups; the treatment group (n = 40) who received 300 mg of ALA twice daily for 3 months and the control group (n = 40) who received placebo for 3 months. Measurements of weight, body mass index (BMI), lipid profile, fasting blood glucose (FBG), malondialdhyde (MDA), tumor necrosis factor alpha (TNF-α), leptin and adiponectin were carried out before and 3 months after the treatment.


ALA treatment group had a significant reduction of the weight, BMI, MDA, TNF-α, and leptin levels but a significant increase of adiponectin level (P < 0.05) compared to the control group. However, it had no effect on FBG or lipid profile (P > 0.05).


ALA may be a promising supplement in the weight reduction in obese children and adolescents.
