Brief Summary

Omega-3 index is used as a proxy for an adequate intake of fish unsaturated fats in the diet. However, omega-3 supplements have not consistently shown the health benefits of eating fresh fish. This study will assess the change in omega-3 index and impact on markers of cardiometabolic health with two different supplements: a whole, unprocessed salmon oil and a standard, processed, concentrated oemga-3 oil. The markers to be studies included impact on inflammation and oxidative stress, cholesterol and markers of risk of diabetes. Change in sleep metrics will also be assessed.
