What should krill oil smell like?

Krill oil should have a mild, oceanic scent, often described as slightly fishy or briny, but not overpowering or rancid. Fresh krill oil typically does not have a strong odor; any unpleasant or overly strong smell may indicate spoilage. It's important to store krill oil properly to maintain its freshness and prevent oxidation, which can alter its scent. If the oil smells off or has an unusual odor, it’s best to avoid using it.
