What is the most frequently reported downside associated with krill oil consumption mirroring fish oil issues?

Gastrointestinal side effects like belching and a fishy aftertaste

The most common adverse effects reported by users of krill oil, which are frequently shared with standard fish oil supplements, center primarily on the digestive system. Specifically, many individuals experience belching that carries a noticeable fishy aftertaste, commonly referred to as 'fish burps.' In addition to this, other documented gastrointestinal distress symptoms include heartburn, nausea, and a general feeling of stomach upset. Furthermore, consuming higher quantities or taking the supplement without food can sometimes lead to looser stools or diarrhea. While the phospholipid structure of krill oil is sometimes suggested to reduce the frequency of these issues compared to triglyceride-based fish oils, these digestive complaints remain the most common hurdle for daily users.
