Omega-3 Supplementation After Surgical Treatment of Obesity

Early Phase 1

Completed

• Conditions: Obesity

• Registration Number: NCT06494566
• Lead Sponsor: Instituto de Cardiologia do Rio Grande do Sul

Brief Summary

The study evaluates diet supplementation of Omega-3 fatty acids after surgical treatment of obesity in adults. Half participants will receive diet supplementation of Omega-3 fatty acids, while the other half will receive placebo.

Detailed Description

Omega-3 fatty acids has been related to immunomodulation and antioxidant action. Diet supplementation of Omega-3 fatty acids after surgical treatment of obesity may help stabilize protein catabolism, reduce peroxidative damage, and improve lipid profile.
