Effects of Docosahexaenoic Acid (DHA) on Cardiovascular Disease on Diabetic Patients
Intake of Low Dose of Docosahexaenoic Acid: Effects on Platelet Functions and Redox Status in Diabetic Patients
Aim: to determine the effects of DHA supplementation:
- on the platelet function through their aggregation and the pathway of arachidonic acid metabolism
- on redox status on cells and plasma
- on inflammation in 16 type 2 diabetic patients in a cross-over study comparing DHA (400 mg/day for 2 weeks) vs Sunflower oil (placebo). Each period is separated by a wash-out period of 6 to 9 weeks.
