Antarctic Krill represent a particularly healthy source of the omega-3s eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids are among the most researched nutritional ingredients in the world today, according to the Global Organization of EPA & DHA Omega-3s.
The human body has limited ability to produce EPA and DHA, so it is vital that they are consumed through diet. Most consumers, though, fall short of recommended intakes, creating a need to supplement with these important omega-3s.
Beside EPA and DHA, krill oil also contains choline, an essential nutrient as well as a biochemical building block of all cell membranes, as well as a neurotransmitter precursor.
Omega-3s and choline represent a critical part of life found in every cell in the body. Unfortunately, most diets globally feature inadequate amounts of omega-3 fatty acids and choline, contributing to about 90% of the American population being deficient in these nutrients.
Both omega-3 fatty acid and phospholipid deficiencies are linked to damaged cell structure and decreased fluidity, which can result in cell dysfunction. Cellular dysfunction has been linked to health conditions of the heart, brain, liver, joints, and so on. Furthermore, omega-3 deficiency is purported to contribute to diseases that are rooted in inflammation, such as heart disease, Alzheimer’s/dementia and arthritis.
But it’s not only the omega-3s that set krill oil apart; it’s other nutrients as well, such as phospholipids, choline, and astaxanthin. And each nutrient in krill oil seems to have its own unique role to play. Compared to other marine sources of omega-3s, Antarctic krill brings a lot more to the nutrition table.
For example, the phospholipids in krill oil are responsible for carrying EPA and DHA into the cells quicker and more efficiently. As part of cell membranes, the omega-3 fatty acids EPA and DHA have the ability to influence fluidity of the membranes, signaling processes, and metabolic parameters in the cell. In other words, the more omega-3 in your cells, the more flexible they are, and the better they function.
In addition, phospholipid-bound omega-3 fatty acids are water dispersible, making them gentler on the stomach and more readily absorbed by the body. And with phospholipid omega-3s, less is more—smaller capsules are easy to swallow and digest.
