Fish oil, depending on the refinement process, may have these natural antioxidants removed, though many modern products add vitamin E or other preservatives to ensure freshness and stability. Fish oil sourcing is more varied; oils from small, short-lived species like anchovy and sardine are generally considered sustainable, while oils from larger, longer-lived predatory fish can raise concerns about heavy metal contamination and overfishing.
The Sustainability of Fish Oil Sourcing
Practical Considerations: Purity and Taste Purity is non-negotiable for any supplement, and both krill and fish oil can be purified to remove contaminants like mercury and PCBs. Krill oil tends to be more tolerable in this regard due to its natural phospholipid structure, making it an easy choice for those sensitive to digestive upset.
On the sensory side, fish oil is infamous for causing burps or a fishy aftertaste, although enteric-coated formulas have largely solved this issue. However, concerns exist about the potential impact on the base of the marine food web.
Addressing Fish Oil Sustainability Concerns
Both sources deliver EPA and DHA, the long-chain fatty acids responsible for heart, brain, and joint support, yet they differ significantly in absorption, sustainability, and additional compounds. Due to their position in the food chain, krill generally have a lower risk of heavy metal accumulation, but high-quality fish oil distillation processes are equally effective at producing clean products.
