[Research progress on the effects of krill oil and its active components on adipose tissue function]

In recent years, the global prevalence of obesity has shown a persistent upward trajectory, including significant increases within China. The compromised functionality of adipose tissue in obese individuals leads to chronic inflammation, dysregulated adipokine secretion, visceral fat accumulation, and insulin resistance, all of which are closely linked to the onset of major chronic diseases such as type 2 diabetes and atherosclerotic cardiovascular disease. The implementation of diversified intervention strategies aimed at weight reduction and adipose tissue functional improvement represents an effective paradigm for preventing and managing obesity-related metabolic disorders. Krill oil, an efficacious active ingredient derived from Antarctic krill, is abundant in bioactive compounds such as omega-3 fatty acids and astaxanthin, and exhibits health-promoting properties including anti-inflammatory, antioxidative, lipid metabolism enhancement, and insulin sensitivity improvement effects. This study systematically reviews the impact of krill oil and its active components on adipose tissue function, with the aim of providing more effective lifestyle intervention strategies for the prevention and management of obesity and metabolic diseases.
