Krill oil is a very popular omega-3 health food in recent years, mainly extracted from the Antarctic sea of a small red krill, because it is located in the lower layer of the food chain, less prone to heavy metal pollution residues, so it has attracted attention.
Krill oil is special in its special fatty acid structure, about 30% to 65% in the form of phospholipids (mainly phosphatidylcholine, commonly known as lecithin), while the fat in fish oil is mainly in the form of triglycerides.
Unlike triglycerides, phospholipids are the main structure of cell membranes and are also amphiphiles with emulsifier functions, so it is generally believed that the human utilization rate will be higher.
However, as of now, there is no clear conclusion on whether krill oil is bioavailable better than fish oil, and more precisely designed studies are needed to verify it. Note 1
What are the recommended efficacy benefits of krill oil?
1. Krill oil improves knee pain
Knee pain is the most common health problem among the elderly, often seriously affecting mobility, with an estimated prevalence of 50.46% of people over 2 years of age (about 32% of men and 58% of women), which can be said to be unavoidable the longer you live
A double-blind controlled study (30 days, 50 patients with mild knee pain) showed that krill oil improved pain, stiffness, and left and right knee flexibility compared with placebo (as judged by the Japanese Knee Osteoarthritis Scale (JKOM) and the Japanese Society of Osteopathics Scoring System (JOA). Note 1
In addition, the same study also observed that the omega-3 value in the blood increased and decreased the ratio of omega-6 to omega-3, which helped inhibit the production of pro-inflammatory hormones.
*Conclusion: For mild arthritis, oral krill oil has a positive effect on symptom improvement
2. Krill oil improve the state of immunosuppression after exercise
Regular moderate exercise can benefit the immune system and reduce the incidence of respiratory infections compared to sedentary lifestyles.
However, prolonged high-intensity strenuous exercise (e.g., marathons or long-distance cycling) often leads to temporary immunosuppression, usually lasting 3 to 24 hours, greatly increasing the chance of upper respiratory tract infection. Note 1
A randomized, double-blind controlled trial (6 weeks, 37 healthy adults) showed that oral krill oil improved immune status (peripheral blood mononuclear cells (PBMC) and natural killer cell toxicicidal activity) after intense endurance exercise compared with placebo, but did not improve exercise performance. Note 2
*Conclusion: Krill oil consumption does not improve exercise performance, but may help improve immunosuppression after strenuous exercise
3. Krill oil is beneficial regulation of blood lipid status (Hyperlipidemia)
Hyperlipidemia often refers to abnormal values of one or more lipids in the blood, and high cholesterol is the most common, caused by genetics, smoking, obesity, uneven diet and sedentary years.
It is estimated that one in three U.S. adults has dyslipidemia, which causes vascular variation in the long term and increases the incidence of cardiovascular disease by about 2 times.Note 2
A systematic literature review and meta-analysis (7 studies, 662 participants) pointed out that krill oil can help reduce low-density lipoprotein cholesterol (LDL-C) and triglycerides (TGs) in the blood, and may be used as an adjunct therapy option for patients with hyperlipidemia.Note 1
The mechanism behind it may be related to the regulation of the mitochondrial respiratory chain and the inhibition of fat, cholesterol, and liver glucose manufacturing pathways.
*Conclusion: Krill oil has the effect of regulating blood lipids, but due to the heterogeneity of the included studies and the small sample size, more large studies are still needed to further confirm

4. Krill oil improves cognitive function
The human body is a sophisticated machine, running all the time, and with age, poor operation or aging functions are inevitable phenomena.
In contrast, it is easier to see aging from the outside, such as gray hair, wrinkled skin and mobility problems, but in fact, brain aging also occurs simultaneously, resulting in cognitive decline.
A randomized, double-blind controlled trial (12 weeks, 45 elderly men) found that intake of krill oil and sardines oil helped to activate the prefrontal cortex of the brain and promote working memory, thereby preventing the potential effect of cognitive deterioration (although krill oil had a more significant effect on improving computing power).Note 3
The authors believe that this is because the omega-3 fatty acids (krill oil) in the form of phospholipids are more beneficial for improving cognitive function.
*Conclusion: For older adults, krill oil may help to activate cognitive function and is better than fish oil
5. Krill oil improves premenstrual syndrome
Premenstrual syndrome mainly occurs in the luteal phase (after ovulation to menstruation), and has been recorded to include more than 200 kinds of physical, mental and mental discomfort symptoms, and the causes are quite diverse, including hormonal imbalance, nutritional deficiency or excess, increased prostaglandin synthesis, imbalance of neurotransmitters, etc
A double-blind controlled study (90 days, 70 patients with PMS) found that krill oil and fish oil were both associated with premenstrual psychosomatic discomfort (weight gain, abdominal pain, edema, bloating), but other indicators such as analgesic use, mood, breast tenderness, and joint pain showed greater improvement in krill oil. Note 4
*Conclusion: Compared with fish oil, krill oil has a significant improvement in PMS
Are there any side effects of krill oil?
Most studies have found that in the short term (less than three months), the safety of moderate consumption of krill oil is extremely high, but it may still produce side effects similar to fish oil products, including heartburn, bad taste in the mouth, stomach upset, nausea, diarrhea and other phenomena.
Precautions
- Do not use in pregnant women, lactating women, poor liver and kidney function (due to unknown related safety)
- Do not use if you have been allergic to seafood or related products (may induce allergic reactions)
- Because omega-3 has anticoagulant function, it should be avoided two weeks before surgery, if the coagulation function is abnormal, and if you take related anticoagulant drugs
