Some of the common health benefits and medicinal purposes of using krill oil include treating conditions associated with menopause, premenstrual syndrome (PMS), and dysmenorrheal.

Krill oil is also beneficial in pregnant women and nursing mothers, as an anti-neoplastic agent, in postoperative cases, in preventing several carcinomas, in decreasing osteoporosis, for arteriosclerosis, for various cardiovascular conditions like myocardial infarction, for thrombosis, for angina pectoris, for arterial hypertension, in cholesterol-related conditions, and also in reducing various symptoms associated with immunodeficiency.

In addition to the above health benefits of krill oil, this oil is also used in treating conditions associated with memory loss such as Alzheimer's disease, depression, dermatological conditions, as well as in reducing blood sugar. Discussed in detail below are various system-wise benefits of krill oil use.

Obstetrics and Gynecology

Krill oil is widely used in treating several obstetrics and gynecological conditions, like premenstrual syndrome or PMS, painful periods or dysmenorrhea, various symptoms associated with menopause, as well as issues during and post pregnancy.

The health benefits of krill oil extend to PMS or premenstrual syndrome, a condition which includes an entire range of physiological and psychological problems, such as cramps, back pain, headache, dizziness, nausea, vomiting, etc, that effect and interfere with the normal routine activities of a woman. This results in a huge loss of work hours, both professionally and personally. Therefore, it is becoming extremely important to focus on this issue and ensure that women go through very little or no PMS month after month during the course of their lives.

How exactly do the health benefits of krill oil apply to the krill oil and PMS connection?

Scientific studies indicate that there is an increase in the consumption of foods rich in omega 6 fatty acids, especially in the West, as opposed to omega 3 fatty acids, which are beneficial in several ways. These omega 6 fatty acids are processed by the body and result in inflammatory elements like arachidonic acid, which accumulate in the cellular membranes, giving rise to pro-inflammatory prostaglandins.

These prostaglandins in turn increase the inflammatory effect on the uterus, resulting in increased pain or cramps. Thus, omega 6 fatty acids seem to have properties that directly increase pain, whereas omega 3 fatty acids have anti-inflammatory properties that help reduce or combat inflammation. Therefore, it is becoming increasingly important to up the intake of foods containing omega 3 fatty acids, and to decrease the intake of dietary products containing omega 6 fatty acids.

Krill oil is rich in omega 3 fatty acids, and this link between krill oil and inflammation is one of the important health benefits of krill oil.

Besides the abovementioned, the byproduct of omega 6 fatty acids, which is arachidonic acid, is further broken down to produce cyclooxygenase, which triggers vascular constriction and contractions of the lining of the uterus, known as myometrium, creating pain and cramps. In contrast to this functionality of omega 6 fatty acids, the omega 3 fatty acids eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA) help the system create anti-inflammatory prostaglandins, decreasing the vascular contractions of the myometrium and uterus, thereby reducing the associated pain.

Again, the health benefits of krill oil here lie in its omega 3 content. Therefore, krill oil is considered to improve and inhibit various symptoms and issues associated with PMS and painful menstrual periods; this helps to explain the krill oil and PMS connection.

Apart from PMS and dysmenorrhea, the health benefits of krill oil also extend to menopause - it has been observed that several pre and post menopausal problems have been treated effectively with the help of krill oil.

Since krill feeds mostly on plankton that are rich sources of omega 3 fatty acids, krill imbibe the bulk of the omega 3 fatty acids and become powerful storehouses of omega 3. Thus, krill oil contains substantial amounts of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which are two main fatty acids that have numerous properties that help in treating conditions associated with memory loss, depression, cancer, arthritis, and certain cardiovascular conditions.

The omega 3 fatty acids contained in krill oil help increase the antioxidant levels in the human body, and further facilitate a reduction in the psychological symptoms associated with menopause, such as depression and distress. Another major relief experienced by women using krill oil is a significant decrease in symptoms associated with hot flashes; this is also a result of the presence of omega 3 fatty acids in krill oil.

In addition to the above health benefits of krill oil, the presence of antioxidants and omega 3 fatty acids in krill oil also prevents chaffing or peeling of skin - these are problems associated with dry skin, which is another major issue faced by women going through menopause.

The health benefits of krill oil also extend to joint issues - osteoarthritis, rheumatoid arthritis and joint pain, which is also a major cause of concern among women going through menopause. More on this krill oil benefit is explained in the next section.

Thus, besides lowering the risk of myocardial infarction, angina pectoris, arteriosclerosis, and hypertension, as well as reducing the blood sugar in women going through menopause, krill oil also provides direct relief from some of the major symptoms and conditions associated with menopause - these include distress and / or depression, hot flashes, joint and muscle pain, as well as dry and scaly skin.

What a long list of krill oil benefits for women facing menopause.

Joint Krill Oil Benefits

Then, there is the joint krill oil connection - as mentioned earlier, the health benefits of krill oil apply to joint ailments, too.

The biochemical composition of krill oil helps provide considerable reduction in joint and muscle pain, because it creates a cushion-like effect for several tissues and organs. Therefore, for osteoarthritis and / or rheumatoid arthritis, krill oil is effective in providing significant relief from pain and also in alleviating other related symptoms.

While the exact mechanism of pain reduction is being studied, the success of providing pain relief has been associated with the decrease in prostacyclin, thromboxane, and leukotrines, which in turn helps lessen the inflammation and pain.

Heart and Cardiovascular System

Biochemical substances contained in krill oil get processed into prostaglandins that reduce the risk of several cardiovascular conditions, including angina pectoris, myocardial infarction, arteriosclerosis, and hypertension.

Indeed, it is well-known that omega 3 fatty acids benefit the heart and cardiovascular system, and it would thus make sense for this to also apply to the health benefits of krill oil.

Central Nervous System and Brain

Krill oil facilitates the formation and regulation of certain neurotransmitters in the brain - these compounds decrease memory loss and improve brain function. Thus, krill oil is being used extensively in treating people suffering from Alzheimer's disease.

Respiratory System

Krill oil, being a rich source of omega 3 fatty acids and antioxidants, can prove to be extremely effective in reducing inflammation and facilitating smooth respiration, especially in people suffering from respiratory conditions like wheezing and asthma.

Yet more exciting health benefits of krill oil.

Skin and Cells; Teeth

Another of the health benefits of krill oil relates to the skin - krill oil helps regeneration of the human body at the cellular level, thereby promoting the rejuvenation of skin, hair, and nails. In addition, krill oil also helps reduce tooth decay and cavities.

Anti-Diabetic Properties; Cholesterol Control

Krill oil has the ability to decrease the levels of LDL cholesterol or bad cholesterol, as well as increase the levels of HDL cholesterol or good cholesterol, thereby regulating blood sugar levels in the human body and ultimately controlling diabetes. Thus, krill oil is found to be effective in treating and preventing diabetes.

Anti-Carcinogenic Uses

The health benefits of krill oil may also extend to cancer and tumors.

Scientific studies indicate that the DHA and EPA present in krill oil decrease or sometimes reverse the development of colon carcinoma, provided it is detected and treated with krill oil in its early stages. During latter stages, however, it might not prove to be effective in treating the same.

Also, due to the presence of significantly huge levels of omega 3 fatty acids, krill oil has been found to be extremely effective in treating breast and prostate cancers, too. Thus, a healthy intake of krill oil might be a step in the right direction, especially for those who are at higher risk of developing breast and prostate cancers.


Krill oil contains a caratenoid called astaxanthin, which is a very potent antioxidant contributing to the health benefits of krill oil.

Krill has a reddish-pink color, which originates from the algae eaten by it. This pigment is astaxanthin, whose health properties include the provision of strong defense against ultraviolet radiation, and it is making krill oil a very much valued nutritional supplement today.

Other Health Benefits of Krill Oil

In addition to the above, krill oil is used as a form of natural medicine in treating people suffering from certain disorders, such as anorexia and obesity.

Krill oil also contains vitamin A, vitamin D, and vitamin E.
