Krill powder is a food supplement rich in active ingredients such as fatty acids, phospholipids, protein and antioxidants like astaxanthin. It is considered to be more effective in lowering triglyceride values than fish oils and it may have positive effect on cholesterol values as well. Krill proteins may have positive effect on blood pressure and astaxanthin has anti-oxidative and anti-inflammatory properties. Thus, krill powder has a lot of potential in improving lipid values and having other positive health effects on cardiovascular system. However, there haven't been many clinical studies done with krill powder and thus systematic data on human safety is limited.
