Conclusion of Our Kirkland Signature Fish Oil Review

After thoroughly researching information for our Kirkland Signature Fish Oil review, we have come to the conclusion that this fish oil supplement is worth taking into consideration. What we like about this product is that it makes use of pure fish oil harvested Peruvian sardines and anchovies for omega-3 fatty acids which are then purified to get rid of any mercury. Both Amazon and Costco customer ratings are solidly positive and the the product is affordable. The money back guarantee from Costco also makes it an attractive buy.

However, if you are looking for a fish oil supplement that comes at a higher dosage, you should look at other options.
