bioavailability of epa and dha from two dietary supplements

Conditions: Hypertriglyceridemia

Summary: the primary objective of this study is to test the effects of two different fish oil products containing dha and epa by comparing the omega-3 fatty acid levels in the blood.

the objective of this study is to evaluate and compare the acute and sub-chronic (2 week) bioavailability of epa and dha from two marine oil supplements consumed with a meal in men and women with mildly elevated triglycerides. the supplements provide similar amounts of epa + dha esterified as either triglycerides; or esterified as phospholipids and triglycerides.
