Frequently asked questions
- How is krill oil different from fish oil?
- Krill delivers its EPA and DHA bound to phospholipids rather than as triglycerides or ethyl esters, and it naturally contains astaxanthin, the antioxidant that gives the oil its red colour.
- What does USP Verified mean?
- USP Verified means the product is independently checked for identity, purity, potency and manufacturing quality. It is a quality-and-purity mark — not a banned-substance certification for tested sport.
- Is it suitable for vegetarians?
- No. It is krill-derived, and the softgel shell uses bovine gelatin.
- What format is it?
- A once-daily softgel. Kirkland Signature is Costco's own-label brand.
