good quality I was told by a nutritionist to take this every day and it has helped my joints. Leaves no after taste and goes down easy. September 2, 2013
Best Value Ever The quality and price of this product says it all. June 22, 2013
Best Cod Liver Oil My midwife suggested taking cod liver oil with my second pregnancy. I found this brand and thought it was a good deal so I tried it. There is no after taste or burping up the oil! I feel it is a great product! May 2, 2013
Good Product Good product, but bottle was much smaller than I expected. March 13, 2013
Cod liver oil Small caps that are easy to swallow, have no after taste and while not specifically burp less, they cause me no trouble. November 13, 2012
Trusted quality I couldn't find a better quality cod liver oil anywhere! The store brands don't tell you where their's come from. But Swanson's brand is not afraid to tell you up front. November 10, 2012
No burping or fishy taste afterward November 5, 2012
Great Product! Great products. Love its many health benfits. But Krill Oil is even better. But I will be switching to New Chapter Wholemegas because of its 16 omegas complex form even better yet....... November 2, 2009
