Bioavailability of EPA and DHA From Two Dietary Supplements

Not Applicable
Conditions
Hypertriglyceridemia
Interventions
Dietary Supplement: DHA-rich fish oil versus Phospholipid-rich fish oil
Registration Number
NCT01908374
Lead Sponsor
Arctic Nutrition AS
Brief 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.

Detailed Description

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.

Primary Outcome Measures
NameTimeMethod
Area under the curve for plasma phosphatidylcholine omega-3 fatty acidspre-dose, 1, 2, 4, 6, 8, 10, 12 hours post-dose

The primary outcome variable will be the net incremental area under the curve (niAUC) for plasma phosphatidylcholine (PC) EPA + DHA from pre-meal (t = -0.5 h pre-dose) to 12 h post-dose (niAUC 0-12 h post-dose) measured at visits 2 and 4 (analyzed with and without normalization to the intake of EPA+DHA in each group).

Secondary Outcome Measures
NameTimeMethod
