13 Science-Based Health Benefits of Krill Oil

Omega-3 fatty acids are powerfully beneficial to your health. Omega-3s boasts an abundance of benefits including improving cognitive function, improving mood, and reducing your risk for many diseases.

In fact, omega-3s reduce the risk of autoimmune disease, heart disease, rheumatoid arthritis, depression, anxiety, Alzheimer’s, cancer, asthma, age-related macular degeneration and more.1

Found in oily fish, krill, and some plants, it’s important to be sure you’re getting enough omega-3s. But, fact of the matter is most Americans are not getting enough omega-3s, especially two important kinds - EPA and DHA - which are only found in marine sources.2 This is because the modern diet is largely comprised of processed foods and void of wholesome nutrients.

The importance of omega-3s coupled with the serious lack of them in our modern diet makes omega-3 supplementation a smart idea for nearly everyone. In comparing different omega-3 oil sources, we found krill oil to be the best option because of its stability, bioavailability, potency, the presence of EPA and DHA, and the reduced likelihood of heavy metal presence (because krill are lower on the food chain). 

Here are the top 13 science-based health benefits of krill oil


1. Protects the Brain

Omega-3 derived from krill oil reduces oxidative brain damage and prevents brain disorders including dementia, epilepsy, and autism.3

An added bonus of krill oil is that it contains phosphatidylcholine, which is partly choline – a precursor to the important neurotransmitter, acetylcholine. Choline is important in memory, learning, and brain development.4

Krill oil has also been shown to prevent cognitive decline in the elderly. In one study, the phosphatidylcholine present in the krill oil made it more effective than fish oil.5

2. Boosts Mood

Omega-3s are great for improving your mood and reducing depression.6 Specifically, krill oil has proven to reduce depression symptoms and in one study, did so better than fish oil. Meaning it might be a good idea to try supplementation if you struggle with mild depression.7

3. Reduces Inflammation 

Inflammation has been linked to a number of diseases including heart disease, Crohn’s disease, and rheumatoid arthritis.8 Fortunately, krill oil reduces inflammation in the body by reducing the C-reactive protein and TNF-a, two markers of inflammation.9 Also, supplementing your diet with krill oil helps improve your omega-3 to omega-6 ratio, which further reduces inflammation.

4. Improves Arthritis

Arthritis can be a debilitating condition that makes the simplest tasks painful. Arthritis is caused in part by inflammation of the joints, which can be improved with krill oil supplements. Studies have found that krill oil reduces inflammatory cytokines, stiffness, pain, and functional impairment caused by arthritis.10 

5. Improves Symptoms of Diabetes

Krill oil is very effective against symptoms of diabetes. It’s been shown to balance blood sugar levels and improve insulin resistance.11 Krill oil also lowers the C-reactive protein, which improves diabetes-related inflammation. It also increases good cholesterol, which helps combat bad cholesterol – another common contributor to diabetes.12

6. Turns on Important Metabolic Genes

Did you know your DNA has switches that can turn genes “on” and “off?” It’s true! Our DNA isn’t as fixed as we once thought. And studies have found that krill oil can help turn on some of these good genes that help boost metabolism.13

7. Lowers Bad Cholesterol

In studies on patients with high cholesterol, krill oil was effective at lowering their total cholesterol levels by 13 to 18 percent. This result was compared to fish oil supplements, where patients only saw a 6 to 9 percent reduction in cholesterol levels.14 If you’re struggling to manage your cholesterol levels, krill oil could be a safe and natural option for you. 

8. Alleviates PMS Symptoms

Krill oil helps women with cramping and emotional symptoms of PMS. We learned earlier about how krill oil can be a mood booster, but studies specifically on PMS found women suffered less depression. Additionally, they needed less analgesics, such as Advil, for cramping.15

9. Reduces Overeating

Endocannabinoids influence your mood, memory, and motivation by stimulating the immune system. When your endocannabinoid system is out of whack it can cause weight gain, blood sugar issues, and overeating. Krill oil helps your endocannabinoid system function properly and makes you feel full faster.16

10. Prevents Heart Disease

The heart benefits of omega-3 and krill oil have been well studied. Krill oil reduces inflammation, lowers triglyceride levels, and reduces overall risk of heart disease. One study that compared krill oil and fish oil on cardiovascular health found krill oil to be significantly better. The researchers even called on physicians to recommend krill oil to their patients.17

11. Fights Cancer

Studies have found that krill oil effectively suppresses cancer cell growth and kills cancers cells. Though there is a need for further studies in this area, many agree that krill oil may be an effective chemotherapeutic option for cancer down the road.18

12. Relieves Dry Eyes

You might be surprised by this one, but krill oil helps alleviate dry eyes. Studies have found the phospholipids in krill oil are effective at improving tear production. Krill oil also reduces proinflammatory cytokines that contribute to dry eyes.19 Krill oil could help you relieve your dry eyes from the inside out. 

13. Improves Mitochondrial Function

Your mitochondria are the powerhouses of your cells. They make the energy molecule ATP, which every cell in your entire body needs to survive. Mitochondria are so important that if they stopped working for seconds you’d die – it’s actually how the poison cyanide works. Krill oil supports your mitochondria by regulating the mitochondrial respiratory chain. This important process keeps you healthy and youthful.20

There’s mounting evidence that omega-3s can drastically reduce disease risk. Additionally, studies comparing omega-3 sources find krill to be an extremely potent option. 

Krill oil offers benefits for people struggling with medical conditions and anyone looking to improve their health overall. Add krill oil supplements and reap these health-boosting benefits. 

We did the research and decided that krill was the best choice in omega-3 supplements. It’s how we came to formulate our signature K-REAL krill oil supplements. Our K-REAL krill oil supplements are packed with healthy omega-3s, potent, oxidation resistant, and free of heavy metals and toxins.
