Description of intervention(s) / exposure
This is a dose-response study therefore participants will be randomized to one of 4 dose groups (0, 0.3, 0.7 or 1.0g/day) of long chain omega-3 fatty acids (Nu-Mega DHA-rich tuna oil capsules, 500mg).
Duration is 2 menstrual cycles (approximately 8 weeks).
0.3g/day group consumes 2 tuna oil capsules and 4 placebo capsules per day; the 0.7g/day group consumes 4 tuna oil capsules and 2 placebo capsules per day; and the 1.0g/day group consumes 6 tuna oil capsules per day. These 3 dose groups will be compared to 1 placebo group which consumes 6 placebo capsules per day (Sunola oil).

Comparator / control treatment
Placebo Sunola capsules, taken for 2 menstrual cycles (approximately 8 weeks). 0g/day long chain omega-3 polyunsaturated fatty acid (LCn3PUFA) group will consume only placebo capsules (6 per day).

Outcomes
Primary outcome [1] 3457 0
Fasting plasma triglycerides (measured using an autoanalyser (Konelab, Thermo Electron) and standard assay kits.
Timepoint [1] 3457 0
At baseline and approximately 8 weeks after start of intervention (2 menstrual cycles)
Secondary outcome [1] 5761 0
Lipoprotein levels and particle size (VLDL, IDL, LDL and HDL). Lipoproteins will be isolated from plasma using sequential ultracentrifugation. Particle size will be determined using gradient gel electrophoresis, and composition analysis will be conducted using an autoanalyser.

Summary
Brief summary
This project aims to determine the dose-response effect of low doses of long chain omega-3 polyunsaturated fatty acids on plasma triglyceride levels in pre-menopausal women with mildly elevated triglycerides. The dose-response effect on plasma lipoprotein levels and particle size, as well as omega-3 levels in various blood samples (plasma, erythrocytes, whole blood from fingertip) will also be investigated.
