I have arthritis but can't take NAIDs so after searching the web decided to take krill oil to get mega doses of omega 3. I've been taking it for about 2 months now and there has been a little improvement in the painlevel but the bonus has been my skin, hair and nails have become so much improved. In cold weather my lips and fingers usually split, the nail shatter and my hair becomes brittle. Not so this winter - I don't feel the need use body lotions, hand or face cream, though I do for extra protection against the icy winds we're having at the moment. It's been a side effect that has been so welcome that I will carry on with my krill oil and hope that my back,hips and knees will respond soon. Hoping you all have a wonderful, blessed Christmas and best wishes for the new year.
