Captains Krill Oil is harvested fresh in the pristine waters of the Southern Ocean off Antarctica. Because this is pure krill oil, straight from the boat, it is processed in very small runs. Which leads to a limited supply that often goes out of stock. This allows you to get fresher, better quality krill oil at an incredibly low price! ******** Captains is the Only Krill Oil with a Money Back Guarantee. After a multi-year study, we can now confidently make the first guarantee in the krill oil industry! We are so comfortable that if you commit to taking Captains every day for 6 months, well guarantee you and your doctor are surprised & amazed or well give you your money back no matter what retailer you purchased from. No fine print, no hoops to jump through. The others can not make this kind of guarantee because their krill oil is not as nature made it. Their krill oil is frozen, its extracted with chemical solvents, some even allow it to sit in large drums waiting to say its bottled fresh just a few days ago. With Captains, you wont have to wonder youll be amazed or youll get your money back.
