good info JL on Krill oil thanks,
Krill Oil – Although krill oil has omega-3s and some antioxidants, it is usually contaminated. Krill are tiny shrimp, approximately one to six centimeters in length, and are a dietary staple for whales, small fish, and seabirds. To extract their oil, they must be soaked in hexane, a chemical found in gasoline and treated with acetone, a chemical found in nail polish remover. Krill oil also has a large amount of what is called free fatty acids, which are short-chain fatty acids that are unstable and oxidize (become rancid) quickly.
