Clinical Study to Assess High-DHA Fish Oil on Biomarkers of Cardiovascular Disease Risk in Adults on Statin Therapy

Clinical Study to Assess the Acute and Chronic Effects of a High-DHA Fish Oil on Fasting and Post-Prandial Biomarkers of Cardiovascular Disease Risk in Adults on Statin Therapy.

The objective of this study is to determine the acute and chronic [4-week] effects of a high-DHA fish oil supplement on fasting and post-prandial (post-meal) biomarkers of cardiovascular disease risk, in adults on Statin therapy.

Studienübersicht

Detaillierte Beschreibung

This study involves fasted and post-prandial components.

Fasted Study:

Participants will provide fasting blood samples pre-and post-intervention [4-week administration of supplement or placebo] in Treatment Period I. Participants will again provide fasting blood samples pre-and post-intervention [4-week administration of supplement or placebo, opposite to Treatment Period I] during Treatment Period II.

There will be a 4-week washout period during the two Treatment Periods.

Post-prandial study:

Participants will also complete a post-prandial study pre-and post-intervention during each Treatment Period.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: 1 (Dietary Supplement - Fish Oil)

On Day 1 & Day 29, the researcher will obtain anthropometric measurements as specified in the study protocol. A venous catheter will be inserted and a fasted blood sample will be drawn, which will be analyzed for study primary and secondary endpoints. Participants will consume a Breakfast Meal (which will represent t0) and will have blood drawn at a total of 7 time points. Blood samples drawn at30, t60, t120, and t180 will be analyzed for glucose and insulin; blood samples drawn at t60, t120, t180, t240, t300 and t360 will be analyzed for triglycerides. Upon completion of the 6 hour blood draw period, the venous catheter will be removed.

On Day 15, the researcher will obtain anthropometric measurements as specified in the study protocol.

On Day 1 and Day 15, participants will receive a 2-week supply of study supplements and will be instructed to consume 4 capsules per day. Each capsule contains 1000 mg of fish oil [620 mg of DHA and 150 mg of EPA], providing a total daily dosage of 4000 mg of fish oil [3080 mg of DHA+EPA].
Experimental: 2 (Placebo)

On Day 15, the researcher will obtain anthropometric measurements as specified in the study protocol.

On Day 1 and Day 15, participants will receive a 2-week supply of study supplements and will be instructed to consume 4 capsules per day. Each capsule contains 1000 mg of olive oil, providing a total daily dosage of 4000 mg of olive oil.
