Double-Strength Cod Liver Oil 5 5 3 3
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
