Compared to regular fish oil, krill oil dangers are relatively minimal.
Krill oil is generally regarded as a superb method for getting omega 3 fatty acids into the diet. These compounds promote healthy brain function, immunity, and protect against age-related decay.
The side effects are not equivalent with those of fish oil, which is at risk of decaying quickly. Here is a summary of some of the environmental and physical concerns which generally come up regarding krill oil, as well as a breakdown of why this natural supplement remains important for overall wellness.



- Source of EPA and DHA Omega-3's
- Contains astaxanthin - a potent anti-oxidant
- Supports brain & cardiovascular health
Krill Oil Dangers
Related Topics
Krill is a small shrimp that lives in cold ocean areas like the Pacific and Antarctic.
It is widely harvested for food and oil in amounts up to 110,000 tons per year.
This is a tiny amount compared to the total biomass of krill worldwide, which could be as much as 500 million tons. Krill is perhaps the most potent marine source of omega 3 fatty acids available to humans.
However, there are certain concerns relating to all fish crustaceans, and animals which come from the sea. These are largely related to environmental safety issues.
All sea life is subject to microbial impurity, heavy metal content, and oxidation damage. Krill are largely thought to be resistant to impurities and metals. They are also resistant to oxidative decay, and their oils are highly non-perishable after harvest.
Still, farming technique plays a huge role in the purity of any organic product. For this reason, it is important to read any manufacturer info provided with a fish oil or krill oil product.
Once consumed, many fish oils present light side effects consisting of fishy odor to the breath and sweat. This effects is notably less present with red krill-sourced oils. Both types of oil can also present stomach upset in some people. None of these issues are considered major krill oil dangers.
How Long Does Krill Oil Stay Fresh?
Krill oil has a shelf life lasting up to two years. It does not decay easily, as fish oil does.
This is important because when these oils decay, they transform into dangerous free radicals. These oxygen-damaged molecules are largely responsible for most age-related decay of organs and brain function.
How Does Krill Oil Work?
Krill oil and the omega 3 fatty acids it delivers represent a vital component of cellular health which has a ripple effect throughout all systems of the body.
Omega 3 acids, comprised of DHA and EFA (docosahexaenoic acid and eicosapentaenoic acid), are good fats which are used to support the health of cell membranes. By making these membranes more permeable, omega 3s contribute to strong organ function and immune response.
As these acids are able to easily cross the blood brain barrier, they also facilitate better brain function, improving cell signaling ability.
The high phospholipid content in krill oil works as a powerful antioxidant, defending brain cells against the oxygen-related decay of free radicals. This decay is a chief cause of degenerative age disorders like Parkinson’s Disease.
The phospholipids in krill oil also contain significant amounts of choline, a vital nutrient for neural tissues. The choline content of krill oil makes it an excellent mental health supplement. None of these effects come with any significant krill oil dangers.
Why Do People Take Krill Oil?
Krill oil provides a wealth of significant benefits with regular use. In the body, krill oil can promote strong immunity and more efficient organ function.
One of the organs which benefits the most is the heart. Skin condition also improves dramatically with regular use of krill oil. Chronic skin disorders as well as the visible signs of aging are both improved.
In the brain, krill oil supplements promote better memory function and reasoning abilities. Stress related thoughts are easier to manage, resulting in better mood and relief from mild depression and anxiety symptoms.
Krill oil is a valuable neuro-protectant, and can prevent symptoms resulting from age-related decay of brain tissue. It is often given to Alzheimer’s patients for this reason.
Final Recommendation – Are Krill Oil Dangers Serious?
Krill oil dangers such as environmental contamination are not a serious concern, provided the product is harvested and packaged in a responsible way. The health benefits of a daily krill oil supplement far outweigh any possible light side effects. These benefits include system-wide immunity and organ support.
The mental effects can include heightened concentration, better memory, and protection from disease. Many of these benefits may arise from the presence of choline, another well-known supplement for cognitive enhancement.
Unlike fish oil, krill oil does not decay easily. It also provides additional anti-oxidant action not found in regular fish oil. All of these factors make krill oil a vital component of a comprehensive physical and mental supplementation program.
