“I have been using butter oil and fermented cod liver oil for more then a decade and they continue to support my knees and back. I started because my chiropractor suggested them for swelling in my knees. I found they reduced back problems, but didn’t think they worked for my knees, until I ran out after more then a year and my knees swelled and became a problem. I have continued to continue to gain the positive results of these 2 two products which I use in combination and am very happy with the product.”
