Double-Strength Cod Liver Oil 4.7 5 20 25
Prefer Over Fish Oil I believe this has all the benefits of fish oil plus the added ones of vitamins A and D March 19, 2014
Use cod liver oil I have been satisfied with all of the products that I have purchased from Swanson's. I have been a customer for many years. I feel that what I purchase will be the best available products for my health. February 15, 2014
Conditioner I have this product together with the Shampoo. It works great and you only need a little bit. December 2, 2013
Excellent Cod Liver Supplement, Excellent Value I buy this Cod Liver supplement for my wife. She says it's the best. She's been using it for the last 3 years and is very satisfied! November 29, 2013
good product, like fish oil with vitamins I take one with lunch daily to keep vitamin d levels up in the winter. It's just a bonus to get some epa/dha and vit a too. November 29, 2013
Double Strenght Cod-liver oil I love it because I don't burp it and have an after taste. September 24, 2013
All around good product Convenient because just one pill does the trick, separate vitamins for A and D are not required, and it doesn't smell fishy. I started taking these because it was recommended for helping with female problems, and I think it has been helping some. September 12, 2013
Excellent Product These cod liver oil capsules are excellent value and good source of Omega 3, and Vitamins A & D. There is no "fishy" taste. I will continue buying these. August 11, 2013
THE VITAL ONE Of all the food supplements i take i'd say this is the vital one. July 6, 2013
best deal Best price on natural CLO I could find. According to Swanson it retains natural vitamins a and d not synthetic vits readded after processing like other brands June 16, 2013
It works! My cousin in Paris told me to take Cod Liver Oil for my joints. I've been using Swanson's for years...I recommend CLO to all my friends....women and men! June 1, 2013
Pleased with Product I travel with my job and these cod liver oil pills are much easier to carry with me than a bottle of the oil. Cod liver oil helps my cardiovascular system. This product is a great combo of quality and value. May 24, 2013
Overall Good Buy This product comes at great price. The quality seems good. The pills are small enough even my younger children can swallow them. March 12, 2013
Hard to swollow It doesn't bother my husband but it's a issue with me. March 12, 2013
Double-Strength Cod Liver Oil Both the wife and I take this important supplement for overall well being. February 23, 2013
Do your home work I bought this product because I was running low on my normal code liver oil and this claimed 'double-strength'. Unfortunately when I received it actually has less total omega-3, DHA and EPA then any of the fish or cod liver oil products I already had. Not sure what the double strength refers to but obviously not what I was looking for. February 4, 2013
great product, great price I take cod liver oil as part of my daily fish oil regime. I've used this product for a few years and think it is wonderful. April 19, 2012
Cod Liver Oil+ Tumeric My older brother told me to take tumeric with oil base and told him I was taking the double strength cod liver oil. I feel great about taking this product and glad to not be wearing my reading glasses today while writing this. I heard a good program with t he Men are from Mars author and glad to have purchased the Lithium orotate and aspartate from Swanson's also. Of all the surveys about companies I would miss if they went away Swanson's would be one of the main ones. I have to check if they sell chocolate:) March 29, 2012
quality product I really like the high level of vitamin A and the balance of vitamin A to vitamin D in this cod liver oil. That means I can get the level of vitamins I need with less product. We have been taking this cod liver oil for over a year with good results. No fish burps, either! March 17, 2012
Great for travel Normally I take the liquid cod liver oil, but it has to be refrigerated. This is great for when I travel and the higher dosage allows me to take fewer "pills" to get the quantity I need. I no longer buy from local stores, but through Swanson along with most of my other nutritional supplements & vitamins. I greatly appreciate the high quality products from a large range of manufacturers at best-value prices with easy convenience ordering and prompt delivery that I've found at Swanson. Thank you for your excellence. You are a God-send! October 17, 2011
