Health Benefits Of Krill Oil

Krill oil is a potent antioxidant that has several health benefits. The high levels of omega-3 fatty acids in krill oil boosts metabolism, manages obesity, tackles depression, and ensures heart health. Also, it works toward easing conditions like ulcerative colitis, arthritis, glycemia, and even cancer. Additionally, its anti-inflammatory properties can protect the skin from oxidative damage and prevent acne breakouts.

Extracted from a species of the Antarctic krill, the krill oil has been in use for several decades. Taken as a dietary supplement, krill oil carries a high nutritional value. It’s also known for its abilities to treat a host of health ailments, ranging from arthritis to depression.

Here are 10 ways in which krill oil can benefit your health:

1. Keeps Your Heart Healthy

Heart disease is the topmost cause of death in the United States. Including krill oil supplements in your diet can help reduce your risk. Although these results are not conclusive, most experts strongly believe that the omega-3 fatty acid content in krill oil can ward off heart disease.1 Krill oil is also effective in slashing high cholesterol levels in the body, as it can significantly reduce the triglyceride present in body fat. By reducing the “bad” cholesterol levels and increasing the “good” cholesterol in the body, krill oil can promote cardiovascular health.

2. Treats Arthritis And Inflammation

Inflammation is a painful symptom of arthritis, accompanied by pain, stiffness, and difficulty in movement. And krill oil, thanks to the omega-3 fatty acids present in it, can reduce inflammation. The fatty acids reduce the level of C-protein, which is an inflammatory substance present in arthritic patients. Thus, it acts as an anti-inflammatory agent and treats arthritis.2 3

Furthermore, the anti-inflammatory properties of krill oil can also help in the treatment of skin disorders like eczema and psoriasis as well as acne breakouts.

3. Improves Brain Health

Your cognition, learning memory, and mood are essential for a healthy brain function. Krill oil, due to its rich omega-3 fatty acids content, can significantly improve brain activity. The active components of krill oil (DHA and APA) help in brain development and could also reduce your risk of ADHD (Attention Deficit/Hyperactivity Disorder), dyspraxia, and dementia.4

4. Eases Premenstrual Syndrome

The symptoms of the premenstrual syndrome (PMS) include breast tenderness, mood swings, stomach pain, and cramps, which can be relieved with krill oil. An inflammatory hormone, eicosanoids, is responsible for menstrual cramps. Krill oil, which is anti-inflammatory in nature, reduces the pain and minimises PMS symptoms. Furthermore, krill oil can also be used as a supplement for women affected by dysmenorrhea, endometriosis, and menstrual migraine.5

5. Helps Manage Obesity

Rich in omega-3 fatty acids, krill oil is known to tackle obesity. The fatty acids (especially EPA and DHA) are commercially used in the treatment and prevention of obesity. Studies suggest that EPA and DHA work by reducing the feeling of “reward” that is associated with food, thus curbing your food intake and appetite. 6

6. Fights Depression

Along with enhancing brain function, krill oil also has properties that work toward reducing depression. In a study that examined the effects of krill oil supplementation in rats, it was observed that the oil could work as an anti-depressant. The active components of krill oil – eicosapentaenoic acid, docosahexaenoic acid and astaxanthin – are found to be responsible for its mood-enhancing function.7

7. Boosts Metabolism

Again, thanks to the presence of omega-3 fatty acids, krill oil can boost metabolism. And a high metabolic function can reduce the fat-build up in the liver (hepatic steatosis), manage the high concentration of sugar in the blood (glycemia), and lower the cholesterol-level in the blood( hypercholesterolemia).8

8. Treats Cancer

Krill oil could be helpful in the treatment of colorectal cancer, according to latest studies. Touted to be a safe alternative or an effective supplement to commercial treatments like chemotherapy or radiation, krill oil could be beneficial to individuals with colorectal (CRC) cancer. The free fatty acid content in krill oil is believed to have anti-cancer properties at it causes the apoptosis or the programmed death of cancer cells.9

9. Reduces Colon Ulcer

Krill oil is an antioxidant that is proven to reduce inflammation. It minimises oxidative stress in the intestine and protects the colon from conditions like ulcerative colitis. By preventing inflammatory colon and bowel ailments, krill oil can also reduce your risk of colon cancer.10

10. Protects The Skin

A potent antioxidant, krill oil can protect the skin from damage and keep it healthy. By reducing the scavenging effect of free radicals, it reduces oxidative damage to your skin cells. Its antioxidant nature also helps slow down the aging process, while reducing wrinkles. It’s also effective in removing sun tans and moisturizing dry skin.

Krill oil is a surprisingly under-rated supplement. And with all the benefits that it has to offer, krill oil deserves a place in your diet. However, don’t begin to regularly consume krill oil without consulting a doctor. If you notice any side-effects like nausea or diarrhea, get immediate help. Also, remember to avoid krill oil if you’re allergic to seafood.
