Are Costco's Kirkland brand omega 3 fish oil with dha and epa good quality vitamins?

Kirkland is Costco's store brand name.


The same manufacturer bottles the same supplements for dozens of other stores as well.


For Costco or any store to have their own manufacturer, you would be paying a few hundred dollars per bottle instead of a couple of bucks.

they are as good if not better than the name brand.


Costco co-brands with name brands. For example, their Kirkland brand jeans are made by Levi. Levi's are an excellent name brand jean, better than some others out there. Whatever name brand company they have co-branded with has to meet Costco's strict standards to be associated with their Kirkland brand.
