Captains Natural Krill Oil

Cut one open and smell it.

Fresh krill oil smells like the ocean — briny, clean, faintly like shellfish. Rancid oil smells sharp and fishy, almost like old varnish. That fishy burp an hour after an omega-3 is mostly a freshness signal, not a fish signal: oil that aged for months in a drum has a lot to repeat on the way back up. Fresh oil mostly keeps to itself.

Captains is extracted mechanically, right on the boat, and goes into softgels in small batches while the oil is fresh. The smell test is one we are happy for you to run.

Captain's Krill Oil — From a Boat, Not a Factory.

This is not factory krill oil. Captain's is harvested fresh in the pristine waters of the Southern Antarctic Ocean using a continuous mechanical pumping system — krill go straight from the ocean into the extraction process with zero time to decompose.

No chemical solvents. No heat sealing. No additives of any kind. Just krill oil exactly as nature intended — bottled in small batches and shipped directly to you.

Five questions people ask about krill oil

Why does my fish oil make me burp?

Fresh fish doesn't smell fishy, and neither does fresh oil. The sharp, fishy smell — and the burp that tastes like it — is what omega-3 oil starts to do as it ages. Chemists call it oxidation. Omega-3 oils are among the most fragile oils there are: every month in a drum, every degree of heat and every bit of oxygen along the way keeps changing the oil after it's made. By the time some of it reaches a softgel, it has a lot to say on the way back up. So before you give up on omega-3s, ask a different question — not which brand, but how fresh.

How do I know if my krill oil is rancid?

Cut a softgel open and smell it. Fresh krill oil smells like the ocean; rancid oil smells sharp, fishy, like paint or old varnish. Three more signs: (1) a fishy burp — fresh oil repeats less; (2) color — krill oil should be a deep red from its natural astaxanthin, and pale or brownish oil has been through something; (3) heat — softgels that spent a summer in a hot mailbox or warehouse aged faster.

What does fresh krill oil smell like?

Briny and clean, like the ocean, faintly like shellfish. Not sharp, not fishy, not like varnish. Captains softgels are filled in small batches while the oil is fresh; many customers notice a mild, almost cocoa-like smell when they first open the bottle rather than a fishy one.

Krill oil vs fish oil — which one causes the fishy burp?

Less a krill-versus-fish question than a fresh-versus-old one. An oil that sat in drums for months will taste like it, whatever species it came from. Krill oil does carry its omega-3s largely in phospholipid form and arrives with natural astaxanthin, an antioxidant that helps protect the oil — but astaxanthin can't undo months in a drum. Whichever side you land on, ask how it was made: the label tells you the species, the process tells you what's in the capsule.

Is Captains krill oil extracted with hexane?

No. Most krill oil is shipped to a processing plant and extracted with chemical solvents or supercritical CO2, then stored in drums until it's needed. Captains is extracted mechanically on the boat — no hexane, no solvents, nothing added — with only the astaxanthin that was already in the krill. Twenty years, same process.
