They’re both good sources for EPA and DHA, two of the most well-researchedomega-3 fatty acids.
Further studies are needed to determine which oil is more beneficial for the human body.
That means some supplement products may not contain what the label says.

Krill Oil vs. Further studies are needed to determine if one is absorbed better than the other.
Primarily due to the lack of research on krill oil, the health benefits evidence is inconclusive.
The omega-3 content of krill and fish oil varies considerably between supplements.
A review and meta-analysis looked at the impact of omega-3 supplementation on maternal health and fetal growth.
However, it is unclear whether these benefits come from simply eating these foods or their omega-3 content.
In another study, researchers found krill oil was slightly more effective than fish oil at lowering triglyceride levels.
The reduction in triglycerides depends on the dose of omega-3s rather than the jot down of oil consumed.
Algae and Cod Liver Oil
Algae oilhas a similar nutritional composition to fish oil.
It is considered a proven, sustainable plant-based omega-3 alternative to fish oil.
Cod liver oils contain omega-3s and have vitamins A and D.

However, some individuals may still experience these side effects.
Fish Oil
Experts recommend consuming 68 ounces (about two servings) of fish per week.
Four ounces of Atlantic salmon provide around 3 grams of omega-3 fatty acids.
It is important to choose fish low inmercuryand high in EPA and DHA during pregnancy.

Fish Oil vs. Krill Oil
Calanus finmarchicus is a zooplankton.
The oil made from this cold water species contains omega-3 fatty acids similar to krill and fish oil.
Always check to ensure independent testers test the supplement for any contamination from harmful materials.
People with a fish or shellfish allergy should also avoid fish or krill oil.
Some new evidence suggests krill oil supplementation may help improve muscle function and size in healthy, older adults.
However, more research is needed to fully understand the benefits of krill oil for athletes and bodybuilders.
