Effect of Fish Oil on Plasma Triglycerides in Adults

Not Recruiting

Trial ID: NCT00804427


The purpose of this small, short pilot study is to determine the feasibility (e.g., recruitment, dose acceptance, retention) of a future longer trial comparing the effects of two types of omega-3 fats from fish oil on plasma triglycerides. The two types of fish oil are composed of (1) omega-3 fatty acids in triglyceride form; and (2) as esterified free fatty acids (i.e. ethyl esters). Although these two types of fish oil supplements are available to the public, it remains unclear whether they are equally effective in lowering plasma triglycerides.
