When we think Costco, we usually think of bulk value, and the Kirkland Signature Fish Oil is no different.
At an affordable price and a 400 pill count, you can get a quality supplement in bulk. Made from deep water fish that are wild caught, the fish oil in these capsules is of good quality. With a state-of-the-art purification process to remove mercury, you can trust you are getting a safe product.
While you are getting more pills at a lower price, you are also getting a lower omega-3 concentration than some other supplements, which might be something to consider.
