Kirkland Fish Oil Customer Reviews

Kirkland Fish Oil has garnered a mix of customer reviews, with a few users expressing satisfaction with the experience of these capsules, whereas certain users expressing dissatisfaction. Here are a few customer responses:

Burpless and great price!
“I take two of these daily as recommended by my doctor. I’m a senior lady and have been taking fish oil for over ten years now. When I first started taking fish oil within just a few weeks I noticed the little bumps on the back of my arms had completely disappeared leaving my skin soft to the touch. I give credit to fish oil. I get a blood panel and cholesterol done yearly and their are no red flags. I don’t do anything special other than eat well (lots of fresh fruit and veggies) stay hydrated and get plenty of sleep. Yes, I’m somewhat active but not overly. I feel Kirkland Fish Oil keeps everything in check not to mention the reasonable price and free shipping.” – Verified Purchaser

Cheap replacement that doesn’t work.
“As someone else mentioned, they replaced they’re much better formulation with this. The old one broke out EPA and DHA, and it was enteric coated. The total amount of omega 3’s were twice what this is. If you take fish oil for anti-inflammatory properties, this won’t do it. Even 2 won’t do it. Bring back the much better and more concentrated version.” – Jen478

Reformulation for the worse
“The enteric fish oil Costco used to sell was a great product. Now, the formula has been weakened. Bring back old formulation. Costco is becoming really frustrating. You expect to see certain products in store only to find they have been replaced with inferior product. Many other examples of this while shopping, not restricted to vitamin isle.” – flrebroker

Disappointed formulation is changed.
“Wondering why they changed amount of EPA and DHA. New formulation does not break out the EPA and DHA, just gives total 250mg down from 684mg (EPA 410mg and DHA 274mg). Used to have 1200 mg fish oil, now has 1000mg fish oil. Old formulation was one per day, now take one 3 times per day. What makes up the 1000mg if there is only 250 mg of EPA+DHA?” – mspeahoe

inferior to previous product
“This product has only one-third the important ingredients of fish oil (EPA – DHA) as the previous 1200 mg enteric coated product that has now been discontinued for “marketing” reasons. Very disappointed in Costco about this.” – squire630

    Decent budget fish oil but nothing impressive
    It’s… fine. I noticed slightly less joint stiffness in the mornings, but it’s subtle. Capsules are easy to swallow, but yeah — fishy aftertaste pops up sometimes, esp if I don’t take it with food. The omega-3 amount feels kinda low compared to others I’ve seen, so you end up taking more anyway. Price is good, but not a miracle supplement like the label hype makes it sound. Just basic support, nothing dramatic.

    Kirkland Brand Fish Oil review
    Love their fish oil. Scientist which produce another major brand told me to switch. With $$ saved I got a Costco membership.

    After a few days of forgetting to take them, I’ll definitely feel joints. I’ve been on a myriad of other name Brand products but nothing helps as much. Unlike other supplements that your brain makes you feel better, I know there are enough of the right ingredients to help my body.
