Related Topics
Omega 3s are part of a class or organic compounds called essential fatty acids.
They are necessary for healthy bodily function, yet cannot be produced inside the body.
Traditionally, humans acquire them through food sources (such as Alpha Linolenic acid), but we can also use supplements to give the body proper amounts of the substances.
Once consumed, omega 3 acids play a huge role in proper organ function throughout the body. They reinforce the strength of cell membranes and create healthy tissue by facilitating the delivery of nutrients and the removal of wastes.
Their effects are most prominent in all immune functions, in the health and resiliency of skin, and in the detoxification functions of the liver. Omega 3s have also been linked to improved cognitive function and protection against age-related illnesses. It is this area which is of most interest to mental health-related krill oil reviews.
Krill Oil Review
Krill oil’s mechanism of action is a combination of short-term fortification and long-term protection. Its constituent parts, DHA and EFA (docosahexaenoic acid and eicosapentaenoic acid), are taken up by cells throughout all of the body’s tissue matter. There the substance improves the permeability of cell membranes.
As krill oil’s omega 3s can easily cross the blood brain barrier, they have a direct effect upon cognitive function. In the brain, the strengthening of cellular function results in improved signaling and more efficient distribution of physical resources. This results in improved cognitive processing related to memory, reasoning, and concentration.
Krill oil also acts as a powerful anti-oxidant due to its phospholipid content. This material, phosphatidyl choline, fights free radical damage while boosting levels of choline and acetylcholine in the brain. Acetylcholine is essential for proper memory function and communication in the brain.
In fact, it is the presence of acetylcholine which most accounts for the cognitive increases mentioned in many krill oil reviews. There are many supplements which boost acetylcholine levels. Among them, krill oil is one of the safest and easiest to tolerate.
Why People Take Krill Oil
Most reviews and testimonials for this supplement cite immunity and good skin as the prime reasons to take it. In fact, many people first discover krill oil when searching for remedies to chronic skin conditions like acne and eczema. A steady intake of good fats like can improve these problems.
Now, krill oil tablets are gaining ground as a daily brain supplement. Because it boosts brain cell health and acetylcholine levels, this translate into better memory.
It is a common theme in user reviews for individuals to say that taking Omega 3 supplements for two or more months at a time makes them feel more clear-headed and alert.
With continuous use, it can further improve overall mood. By supporting brain function, it makes managing stress triggers and thoughts easier, resulting in relief from mild anxiety.
Krill oil also benefits many functions throughout the body, including alleviating from joint pain, lowering LDL cholesterol, and increasing resistance to the common cold and flu. Any of these are excellent reasons to take the supplement.
User Reported Side Effects
The list of user reported side effects in krill oil reviews is relatively short. While some people experience stomach upset, this is a rare outcome. Another Omega 3 source, regular fish oil, is known to cause a fishy odor on the breath and on the skin when sweating. Krill oil does not seem to produce this effect for most reviewers.
Some experience logs express concern over the connection between krill oil usage and existing shellfish allergies, but there have been no conclusive studies on this to date. The best option for people with this allergy is probably to avoid krill oil, even though no warnings have been issued on the matter by the FDA.
Common Krill Oil Fears
The biggest fear mentioned regarding krill oil supplementation is the possibility of environmental contamination. The oceans are notoriously at risk for pollution from man-made industry and commercial seafaring.
While many fish are known to carry residue of heavy metals for this reason, krill are considered safe. Krill, as a tiny creature less than 5 cm long, is at the very bottom of the food chain in in the ocean, and all of the species above it act as filters for environmental toxins.
Final Review
The benefits of krill oil far outweigh any small side effects it may cause. As a part of a daily health regimen, a krill oil supplement (between 1000 – 2000 mg for most people) constitutes a safe way to deliver omega 3 acids to the body and brain.
Organ function will be strengthened, skin conditions may improve, and most importantly, brain cells will be supported and protected from free radical decay. Choline content within the oil may even be comparable to taking a standalone choline supplement.
As most krill oil reviews state, this easy to take supplement is an excellent way to boost overall wellness.
