Krill oil, derived from Antarctic krill (Euphausia superba) species, is drawing increased attention due to its distinct composition, being rich in omega-3 fatty acids, phospholipids, and astaxanthin. Recent studies highlight the potential benefits of krill oil as a dietary supplement for enhancing various health-related factors. Research indicates that supplementing with krill oil positively affects markers of inflammation, oxidative stress, muscle function, glucose metabolism, and lipid profiles. Additionally, advancements in encapsulation technologies aim to optimize the delivery and efficacy of krill oil supplements. The review outlines the selection of emulsifiers and wall materials, along with techniques employed in creating four novel encapsulation methods for krill oil: micro/nanoemulsions, microcapsules, liposomes, and nanostructured lipid carriers. The review also provides scientific literature on the physiological impacts and underlying mechanisms of krill oil supplementation. It explores its influence on glucose homeostasis, oxidative stress responses, inflammatory pathways, lipid metabolism, and muscle physiology.
