NCT04317079

Brief Summary

This study aims to investigate the potential effects of the administration of hydroxytyrosol, which is an extra virgin olive oil phenolic compound, in doses 15 milligrams and 5 milligrams daily versus placebo for 6 months in anthropometric parameters such as body weight, body fat and visceral fat, in combination with diet, in overweight and obese women.
