Krill Oil Supplements and Long-Term Health Concerns
Krill is a shrimp-like marine animal.
The argument goes that krill is a high source of omega-3 and also contains astaxanthin, a valuable carotenoid antioxidant.
Nutrients can exist in different forms in nature just like synthesis of nutrients in test tubes usually produces a different form than found in nature. It has been found that there is a different chemical structure of krill astaxanthin than salmon astaxanthin. The natural food chain for humans contains the form of astaxanthin that is in salmon.
Krill have very high levels of astaxanthin which appears to be ideally suited to sea dwelling creatures. High levels of one carotenoid have the potential of decreasing absorption of other carotenoids.
Humans require lutein and zeaxanthin to prevent macular degeneration (ARMD). This is not an issue with sea creatures that spend a good deal of their time underwater where their eyes are not exposed to sunlight. Human eyes are exposed to sunlight for a lifetime. Leafy green foods like spinach and kale provide the carotenoids (lutein and zeaxanthin) which are optimal for protecting eyes from direct sunlight. Thus the high levels of astaxanthin in krill has the potential of humans not absorbing lutein and zeaxanthin which could place us at a higher risk of ARMD, blindness, and other diseases. There is also concern that the high levels of astaxanthin may depress the levels of other important carotenoids such as lycopene, alpha-carotene, and others.
Krill is not in the human food chain but we do eat other sea creatures that eat krill. What is going to happen when the harvesting of krill upsets the food supply for sea creatures? Ocean populations of fish and mammals need a source of omega-3 fatty acids as much as we do in order to be healthy. In May of 2010 Whole Foods Markets discontinued the sale of krill oil products for this very reason.
The primary reason for promoting krill as a source of omega-3 fatty acids is cost. Krill are cheap to harvest which allows for a high profit margin on the supplements manufactured from them. There is certainly nothing natural about the human consumption of krill or krill oil. They are not part of nature’s blueprint for human consumption. Nature’s blueprint calls for us to eat things that eat krill.
Data for the bioavailability, utilization, and beneficial effects of krill oil have very poor scientific support. There has been extensive research into the benefits of Salmon Oil as a supplement plus humans have been eating salmon for years and years. In recent years, science has discovered there are actually 8 members of the omega-3 family rather than the DHA and EPA alone. It is necessary that we have all 8 members in order to fully benefit from an omega-3 supplement.
I contribute the use of a quality Salmon Oil supplement to my husband not having a serious heart attack a few years back and also to bringing his blood pressure down to a healthy level. No doubt Salmon Oil has helped us in our aging process over the past 26 years. Despite a tremendous amount of stress in our lives, we are very healthy, active, and 68 years old.
Some benefits of omega-3 fatty acids from Salmon Oil are:
- Critical for proper functioning of the B complex vitamins.
- Mental disorders such as depression, bipolar disorder, attention deficit, schizophrenia, and other cognitive issues such as Alzheimer’s have often responded to a combination of omega-3 fatty acids and B complex vitamins. Fish is called “Brain Food” for a good reason.
- Required for normal growth and development thus important for pregnant and nursing women.
- Affects the optimal function of the heart, blood, arteries and veins, brain, nerves, eyes, joints, skin, and sex organs.
- Reduces the risk of heart disease and can lower blood pressure.
- Useful in preventing and/or treating inflammatory conditions such as arthritis, menstrual pain, psoriasis, and inflamed bowel.
- Helps inhibit cancer and has been known to decrease the number, size, and growth rate of tumors.
- Studies have shown that omega-3 fatty acids can reduce the risk of asthma, even exercise-induced asthma.
Who has the greatest need of supplementing with omega-3 fatty acids?
Those with a family history or who are at high risk for heart disease, psoriasis, hypertension, cancer, or arthritis.
When choosing an omega-3 fatty acid supplement; it should have all eight members of the omega-3 family not just DHA and EPA, should be derived from the human food chain, and it is very important that it has been tested for the many potential contaminants that could cause harm to your health immediately and/or long-term.
