Effect of Different Dosages of Dark Chocolate on Arterial Blood Pressure in Cardiovascular High-risk Patients
Phase 4
Completed
- Conditions
- Hypertension
- Interventions
- Dietary Supplement: dark chocolate 6 g/dayDietary Supplement: dark chocolate 25 g/day
- Registration Number
- NCT00661986
- Lead Sponsor
- University of Leipzig
- Brief Summary
Low habitual intake of low-dose dark chocolate (6 g/day) has been shown to have a beneficial effect on arterial blood pressure in one previous study. The trial will assess if ingestion of a higher but still moderate dose (25 g/day) over 3 months will have a more pronounced effect. The population will consist of cardiovascular high-risk patients only (who will potentially benefit most from blood-pressure lowering).
