Study suggests Omega-11-rich fish oil can lower cholesterol levels in rats

Supplementation with CET03 Cetoleic acid omega-11 from Norwegian marine ingredients firm Grøntvedt Biotech for five weeks resulted in significant improvements in insulin sensitivity and glucose levels.

In a rat study published in the British Journal of Nutrition, researchers from Norway noted that cholesterol, insulin sensitivity, and glucose levels had minimal effects from standard fish oil with EPA/DHA.

The study found that herring oil containing cetoleic acid had a positive impact on cholesterol metabolism in diabetic rats compared to anchovy oil devoid of cetoleic acid.

CETO3

Introduced in 2023, CETO3 sourced from North Atlantic pelagic fish (herring) contains cetoleic acid, also known as omega-11.

Grøntvedt Biotech’s unique processing method from fresh fish to oil in under 30 minutes results in a product with a distinct sensory quality suitable for various applications.

Recent studies have shown that CETO3 omega-11 boosts the body’s production of EPA/DHA more efficiently than standard fish oil, enhancing the body’s internal production of these essential fatty acids.

Study Details

In a study led by Professor Oddrun Anita Gudbrandsen, consuming herring oil with cetoleic acid for five weeks led to a 14% decrease in serum total cholesterol levels compared to other groups.

The study, conducted at the University of Bergen and funded by the Norwegian Seafood Research Fund, highlights the potential benefits of CET03 in reducing the risk of heart disease.

CET03 is the flagship product of Grøntvedt Biotech, a sustainable spin-off from the Grøntvedt Group, with a history dating back to 1830.

The company’s efficient production process ensures minimal waste and a low carbon footprint, with additional benefits such as no fishy smell or taste commonly associated with fish oil supplements.
