While fish oil and krill oil contain the same omega-3 fatty acids, they are present in smaller amounts in krill oil, reports WebMD. Krill oil is effective for treating the pain and stiffness of rheumatoid arthritis and osteoarthritis, and studies show that women who take krill oil for menstrual cramps require fewer painkillers. The oil is also useful for lowering C-reactive protein levels, an inflammation marker frequently found in patients with heart disease. The essential nutrients in omega-3 fatty acids can lower triglyceride and blood pressure levels and reduce the risk of stroke and heart disease. EPA and DHA slow the development of arterial plaque and lower the chance that individuals with heart disease die suddenly due to cardiac-related causes.

Because the study of krill oil, which is not an established treatment, is not as thorough, there is no recommended or standard dose as of 2015, explains WebMD. The American Heart Association recommends two servings of coldwater, fatty fish per week. Salmon, tuna and sardines are good sources of omega-3 fatty acids. Individuals who prefer a supplement can safely ingest up to 3 grams of fish oil daily.
