Krill oil is now being promoted as a better alternative to fish oil supplements. Krill are tiny shrimp-like crustaceans.
Promoters say that krill oil provides similar cardiac benefits as fish oil, but with fewer capsules and no fishy taste.
However, krill oil supplements contain less of the omega-3s EPA and DHA than fish oil supplements. Nevertheless, manufacturers claim krill oil is better absorbed because the omega-3s are in a phospholipid form.
According to the experts at the Natural Medicines Comprehensive Database, “Preliminary evidence shows that a specific krill oil product (Neptune Krill Oil NKO, Neptune Technologies & Bioresources, Inc) can lower cholesterol and triglycerides.”
“But,” they add, “overall there’s much better evidence that fish oil can lower triglycerides and cardiovascular risk.”
Furthermore, krill oil usually costs more than fish oil.
So, the NMCD recommends to prescribers, “For now, advise patients to stick with fish oil. Recommend taking it with food or trying an enteric-coated product if fishy taste is a problem. Suggest krill oil only for healthy people who want to add these omega-3s to their diet but can’t tolerate fish oil.”
