NOW Neptune Krill Oil vs Kirkland Signature Krill Oil

We couldn't find enough data on either option to be able to come to any reliable conclusions. We strongly suggest that you look at some alternatives that also cost around $25.

The NOW Neptune Krill Oil hasn't managed to perform well enough to earn a place in any Krill Oil Supplement roundups conducted by sources that do their own, high-quality, hands-on testing. That alone makes it a hard product to recommend.

As for the Kirkland Signature Krill Oil - it wasn't considered to be a good enough purchase to earn a spot in any roundups conducted by sources that perform objective hands-on testing, which typically indicates that a product isn't worth its asking price.

As a last step, we wanted to do a head-to-head NOW Neptune Krill Oil vs. Kirkland Signature Krill Oil comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
