Differential Thrombogenesis by EPA and DHA Mediated by HDL

Recruiting now · Early Phase 1

Conditions studied: Lipid Metabolism Disorders, Hypertriglyceridemia

In brief

The goal of this study is to learn more about omega-3 polyunsaturated fatty acids supplementation on blood lipid profile and platelets in patients with high cholesterol levels. The purpose of this research is to gather information on the safety and effect of two different fish oils, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Participants will: Visit the clinic 3 times during study checkups, tests and blood collection. Randomized to either the EPA or the DHA supplementation group. Be given a 28-day food and activity log.
