The sea is a heaven of creatures and plants, some with valuable medical significance to human health. Krill are basically crustaceans that resemble shrimp and are fed on by sea animals ranging from blue whales to salmon. They are actually considered to be very nutritious compared to other sea creatures. Other than being loaded with Astaxanthin, a powerful antioxidant, krill are also important sources of omega-3 fatty acids that has for years been reputed for its ability to reduce an individual’s risk of suffering from some of the world’s most fatal medical conditions like heart attacks, some cancer types, various cases of inflammation and even depression.

Through a number of tests conducted by scientists, krill oil has been rated better than fish oil because it is safer, healthier and very potent. It contains both the Docosahexanoic acid and omega-3 fats Eicosapentanoic acid that is hooked up in a two-chain Phospholipid structure. Astaxanthin molecule, a very powerful antioxidant is attached to the EPA. This structure makes krill oil more absorbable, making it easier to enter the mitochondria and the cellular nucleus. Also present in krill oil is a complex phospholipid profile that includes a potent stress-reducing choline source called phosphatidylcholine. The omega-3 fatty acids available in krill oil boasts of superior bioavailability ideal for cell growth and functioning when compared to the omega-3 triglycerides that is found in fish.

Enough about scientific complex and onto to the benefits of Krill oil;


The availability of vitamins A, E and D as well as Astaxanthin in krill oil makes it a potent antioxidant. Tests and comparisons with fish oil have found out that krill oil is 48 times more powerful than fish oil in terms of ORAC (Oxygen Radical Absorbance Capacity). With powerful antioxidants in our bodies, free radicals that contribute to some chronic diseases are kept at bay. Unlike other known antioxidants, krill’s Astaxanthin can bypass the blood-brain barrier and guard the brain, the eye and even the central nervous system from damages posed by free radicals.


Krill oil can tremendously reduce inflammations that can damage the heart. This is according to report of the results from a study that was published in Journal of the American College of Nutrition. In the study, the presence of C-Reactive Protein (CRP) levels in the blood was measured. Examining the CRP levels is one of the best ways to measure the risks of heart damage. It was observed that, after 14 days of daily intake of 300 mg krill oil, CRP levels reduced by a whopping 29.7% and 19.3% after just seven days.


Inflammation in the body is mostly as a result of lower omega-3 levels that further results in other ailments. Krill oil is known to contain various anti-inflammatory characteristics which means that regular dosage can lower your back pain, general joint pain, swelling and inflammatory arthritis. Further studies have found out that some of the symptoms and effects of osteoporosis can effectively be relieved with the intake of krill oil.


Nutrients like choline and omega acids contained in krill oil are very helpful in boosting the normal functioning of the brain and enhance the memory, behavior and cognitive capabilities. Lower Omega-3 levels, especially the DHA and EPA can lead to a decline in cognitive functions. This is according to a study conducted at the University of California, Berkley. After taking krill supplements for 90 days, 30 adults with known attention difficulties indicated a 46% advancement in mental concentration as well as a 48.9% mental focus. Chances of cognitive impairment are really low when taking krill oil supplements due to the ability of Astaxanthin to bypass the blood-brain barrier and remove or bar entry to free radicals.


Control of cholesterol levels in our bodies is not usually easy, especially because of the feeding habits most people are accustomed to. Very few substances can regulate the amount of bad (LDL) cholesterol and the good (HDL) cholesterol. Studies have found out that krill oil is good at raising the HDL cholesterol and reducing the LDL cholesterol and at the same time lower blood sugar. Compared to fish oil, it was discovered that while fish oil can reduce the LDL cholesterol by just 4.6%, krill smashed the same by a massive 34%. At the same time, HDL was increased by 43.5% compared to 4.2% from fish oil.


The skin is very sensitive and an important body part. Aside from taking vitamins for skin, using krill oil can enable you cut the risk of acne outbreaks, reduce symptoms of psoriasis, in particular the itching and redness of the skin making it feel softer and more hydrated. Furthermore, krill contains retinol and Astaxanthin that are best known for their anti-carcinogenic effect. This means that oral or topical use has indicated that krill oil can be used as a cancer prophylactic. Your skin can also be protected from ultraviolet light and UV-induced damage to the skin due to the Astaxanthin found in krill oil.


Your overall health can be improved with the help of krill oil as it strengthens your body’s immune system, regulates the hormone levels of your body, optimizes kidney function, elevates your mood and emotional health, regulates blood pressure, balances your blood sugar levels and supports eye health, among others.


If you suffer from mood swings, obsessive-compulsive disorder (OCD), depression, bipolar disorder and attention deficit and hyperactivity disorder (ADHD), you should consider a krill oil intake. In addition, you can also lower your stress levels that are common in most people.


Apart from the above discussed benefits of using krill oil, there are some other benefits that users are bound to enjoy;

  • Alleviation of premenstrual symptoms in women. The PMS are attributed to lack of Omega-3 acids in the body, which is available in krill oil.
  • Amazing anti-aging properties due to the presence of antioxidants that can be relied upon to wage war against free radicals in your body. With time, you will realize an improved skin texture, fewer wrinkles, thicker hair, and stronger nails.
