11 Best Krill Oil Supplements of 2022

Krill oil supplements are rich in omega-3 fatty acids.

Krill are tiny crustaceans that are eaten by whales and penguins, but they are useful to humans. Like fish oil supplements, krill oil supplements also have various health benefits. 

Krill oil is extracted from small shrimp-like marine animals called krill. Processed krill oils are used as supplements. Krill oil supplements are the best alternatives to fish oil supplements because krill oil is rich in omega-3 fatty acids.

Krill oil vs fish oil

Both krill oil and fish oil contain omega-3 fatty acids such as EPA and DHA, but the fatty acids in krill oil have higher bioavailability, that is, its rate of absorption into the body is more than fish oil.

More research is required to know why krill oil is absorbed into the body more easily than fish oil.

Four health benefits of krill oil include:

1. Helps your heart: Triglycerides increase the risk of cardiovascular diseases. Research shows that krill oil effectively reduces triglycerides and total cholesterol and increases high-density lipoprotein (good) cholesterol. Research suggests that omega-3 fatty acids in krill oil help regulate blood pressure.
2. Reduces inflammation: Krill oil contains a pigment called astaxanthin (the same pigment present in carotenoids). Astaxanthin is rich in antioxidant and anti-inflammatory benefits that fight against the bad effects of free radicals on the brain and nervous system.
3. Reduces arthritis and joint pain: Krill oil reduces the symptoms of arthritis and joint pain. A study involving participants who took 300 mg of krill oil daily for 30 days reported that it reduced inflammation and pain in people with arthritis.
4. Reduces premenstrual syndrome symptoms: Using krill oil may alleviate period pain and other symptoms. A study compared fish oil and krill oil. Although both supplements improved the symptoms, individuals taking krill oil needed fewer pain medications.
