Double-Strength Cod Liver Oil 4.9 5 9 11
GREAT Pricing! I recently purchased this as a deal and the pricing was wonderful. I take these for great skin, hair and heart. I guess they are working (only taken for about a week). The pills are medium sized, so they are pretty easy to swallow and don't have a fishy taste at all. April 11, 2014
Superior Cod Liver Oil This has exactly the same ingredients and is the same strength as other CLO that I was buying, but for less money. I appreciate the value of Swanson products October 3, 2013
Great way to get EFA's into your kids/ These are smaller capsules that my children can easily swallow. They detest chewables or liquids, so they learned to swallow pills at a young age. This is a great way to get high quality EFA's into your kids. September 13, 2013
Cod liver goodness Sally Fallon rates this product high! That's good enough for me:) August 31, 2013
Swanson Cod Liver Oil I have been Taking Swanson Cod Liver Oil For Years Now and Have yet to find Anything that Is a Better Value or more convenient to Buy and use. I like the gel Caps because they are easy to Swollow and leave no after taste.I believe Swanson Brand is the Best Value for My Money August 26, 2013
Tried and Tested As a child, I was given Cod Liver Oil and it was not a good experience. I had to hold my breath and swallow a spoonful followed with something sweet to remove the after taste. Now it comes in oval gels that makes it easier to swallow and the experience is not that traumatic as when I was a kid. The capsule contains the same chemical constituent as the liquid of long ago and as effective. February 14, 2013
Fishy Treats My grandchildren grew up using this product and would ask for "fishy treats" for breakfast and other times of the day. They liked to chew them and now they still want some as teenagers. And yes, they still call them "fishy treats"! April 20, 2012
Great Product for Reasonable Price Very good product for very reasonable price. August 9, 2009
An "all-purpose" supplement... My experience has been that DOUBLE-STRENGTH cod liver oil seems to keep my joints lubricated...and, my complexion smooth and hydrated. I am grateful for having found Swanson's, because I cannot find this specific strength of cod liver oil, anywhere else. October 8, 2008
