Krill Oil - A Natural Remedy for Depression?


Krill Oil - A Natural Remedy for Depression?

Expert Author Phillip Cartledge
Most fish and cod liver oils are in a triglyceride form, but Krill oil is in a phospholipid form which is more stable and has the addition of naturally occurring Astaxanthin which helps the stabilisation process further.
What further advantages are there in a phospholipid form?
Phospholipid-bound omega-3 fatty acids are water dispersible, making them gentler on the stomach and more readily absorbed by the body. And with phospholipid omega-3s, less is more because smaller capsules are easy to swallow, easy to digest, and better absorbed by the body. So no fishy 'burps'.
At present there is only one animal study addressing the effect of krill-derived phospholipids on brain function and that's in rats. The author (Gamoh S,2011) observed that spatial learning ability (for the radial arm maze task) and cell generation in parts of the brain were enhanced after Krill oil administration.
Revealing Recent Research
Recent research undertaken by the University of Bergen supported by Aker BioMarine and the Norwegian Research Council revealed that a daily intake of Krill oil may increase learning and memory and also provide antidepressant-like effects.(Lipids in Health and Disease 2013, 12:6.) These studies using lab animals showed that this oil matched the anti-depressive Imipramine in preventing resignation/depression over the duration of the experiment using the ' Unavoidable Aversive Light Stimulus' test (UALST). This measures the state of depression in lab animals.
Study co-ordinator Lena Burri, PhD, Director of Scientific Writing at Aker BioMarine states: "There is clearly potential for krill oil to aid in the management of depressive disorders, while avoiding sedative effects. The special combination of omega-3 fatty acids in phospholipid form in krill oil might give it a further advantage over other omega-3 sources."
The Scientific & Medical Director of ETAP, Michaël Messaoudi, PhD, commented on the study: "We found that in comparison to Imipramine, administration of krill oil did not lead to sedation, which is a regular problem with classic antidepressants. Instead, krill oil treated animals remained alert and showed improved learning and memory functions, while displaying antidepressant-like effects."
As you can see this is an exciting study that still needs more clinical research to further understand how Krill oil could help people combat depression in a more natural and healthy way.
The added extra for Krill Oil
This oil not only contains both of the Omega-3 fats - EPA & DHA but also contains, according to independent testing, the antioxidant power of:
• Over 300 times the strength of Vitamins A & E
• Over 48 times the strength of Omega-3
• Over 34 times the strength of Co Q-10
Antioxidants help to protect the body from free radical damage. This combats oxidation to cells and biomolecules which helps prevent cancer and heart disease and can also assist in every day health.
