Brief Summary
This study will evaluate the absorption of two different dietary supplements containing the omega 3 fatty acids eicosapentaenoic acid and docosahexaenoic acid over 24 hours via venous blood plasma following a single dose taken at bed time. In addition, the circadian rhythm of fatty acid metabolism will also be assessed following the placebo intervention.

Outcome Measures
Primary Outcomes (1)
The 24 hour Area Under the Curve (AUC) of plasma concentrations of DHA and EPA
In order to assess the absorption and its effect on total exposure of each treatment in comparison to placebo, plasma data will be used to calculate the 24 hour Area Under the Curve (AUC) for the fatty acids DHA and EPA.
24 hours
Secondary Outcomes (2)
Mesor of plasma fatty acids (DHA and EPA)
24 hours
Acrophase of plasma fatty acids (DHA and EPA)
