Here are 13 science-based health benefits of krill oil to back it up...
1. May Provide Brain Protection
Omega-3 derived from krill oil reduces oxidative brain damage and prevents brain disorders including dementia, epilepsy, and autism (7).
An added bonus of krill oil is that it contains phosphatidylcholine, which is partly choline—a precursor to the important neurotransmitter, acetylcholine. Complicated words aside, choline is important in memory, learning, and brain development (8).
Krill oil has also been shown to prevent cognitive decline in the elderly. In one study, the phosphatidylcholine present in the krill oil proved to be more effective than fish oil (9).
2. Can Help Improve Mood
Omega-3s are great for improving your mood and reducing depression (10). Krill oil has proven to reduce depression symptoms and in one study, did so better than fish oil. So, if you’re one who struggles with mild depression, krill oil may be an effective supplement for you (11).
3. May Reduce Inflammation
Inflammation has been linked to a number of diseases including heart disease, Crohn’s disease, and rheumatoid arthritis (12). Fortunately, krill oil can help reduce inflammation in the body by reducing the C-reactive protein and TNF-a, two markers of inflammation (13).
Not only that, adding krill oil to your diet improves your omega-3 to omega-6 ratio, further reducing pesky inflammation.
4. Can Improve Arthritis Symptoms
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 can help reduce inflammatory cytokines, stiffness, pain, and functional impairment caused by arthritis (14).
5. May Improve Symptoms of Diabetes
From balancing blood sugar levels to improving insulin resistance to lowering the C-reactive protein (which improves diabetes-related inflammation), krill oil is extremely effective in treating diabetes-related symptoms (15).
As if krill couldn’t get any better, it does—by increasing good cholesterol, helping to combat bad cholesterol—another common contributor to diabetes (16).
6. Can Promote a Healthy Metabolism
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 (17).
7. May Help Lower Cholesterol
In studies involving 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 (18). If you’re struggling to manage your cholesterol levels, krill oil may be a safe and natural option for you.
8. Can Help Alleviate PMS Symptoms
Calling all women who struggle with PMS symptoms every month: Krill oil may alleviate cramping and mood swings.
Earlier, we learned that krill oil can be a mood booster, but studies that specifically focused on PMS found that women suffered less depression when supplementing with krill. Not only that, but they also needed fewer analgesics (like Advil) for cramping (11).
9. May Reduce Overeating
Endocannabinoids—a type of lipid—have an enormous influence on the regulation of appetite and metabolism. That—in addition to the EPA and DHA found in krill oil—reduces the reward associated with food, helping you to feel fuller, faster (19).
In short, when your endocannabinoid system (ECS) is out of whack, weight gain, blood sugar issues, and overeating can arise.
10. May Promote Heart Health
The heart health properties that krill oil garners are hard to ignore. This small red softgel helps to reduce inflammation, lower triglyceride levels, and reduce the overall risk of heart disease.
One study even found krill oil to be exponentially better than fish oil when it came to cardiovascular health. So much so that the researchers called on physicians to recommend krill oil to their patients (18).
11. May Help Reduce Cancer Risk
Studies have found krill oil to effectively suppress cancer cell growth and kill 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 (20).
12. May Provide Dry Eye Relief
You might be surprised by this one: Krill oil can help alleviate dry eyes. Studies have found that the phospholipids in krill oil are effective at improving tear production, while also reducing proinflammatory cytokines that contribute to dry eyes (21).
13. Can Improve Mitochondrial Function
Mitochondria are the powerhouses of your cells. They make the energy molecule adenosine triphosphate (ATP), something that every cell in your body needs in order to survive.
Mitochondria are so important that if they stopped working for mere 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 (22).
