I was told by a doctor that the Krill oil was far more beneficial than normal fish oils so I changed over. My knees are still sore but no where near as bad as they used to be. A few things I have noticed are my skin tans better in the summer, it doesnt seem to be as dry as it used to. My bad back is feeling a lot better and some days no pain at all. Little subtle changes that I attribute to the Krill Oil. A little fishy taste, hardly noticibly if I happen to burb a while after taking but nothing offensive. I will keep taking them and the convenience to order on line and have delivered is awesome.
