Krill are shrimp-like crustaceans eaten by the blue whale. Krill Oil extracted from these crustaceans contains important phospholipids which include phosphatidylcholine, phosphatidylinositol, and phosphatidylethanolamine. These phospholipids contain a high proportion of EPA and DHA, fatty acids found in fish oils.
Benefit of Krill Oil
A few studies have been done with krill oil which demonstrate it to
have potential benefit in maintaining healthy cholesterol and also to play
a role in premenstrual syndrome and menstrual cramps.

Krill Oil or Fish Oil?
Fish oil has a higher percentage of EPA and DHA fatty acids,
however krill oil has the advantage of having a higher amount of importat
phospholipids such as phosphatidylcholine, phosphatidylinositol, and
phosphatidylethanolamine. Krill oil also contains astaxanthin, an
important carotenoid
antioxidant. Therefore, one option is to use a capsule of each,
or alternate their use. It is difficult to predict in any individual
person whether krill oil or fish oil supplements are more benefiicial. For

Krill Oil research update
Evaluation of the effects of Neptune Krill Oil on the clinical
course of hyperlipidemia.
Altern Med Rev. 2004 Dec;9(4):420-8.
Bunea R, El Farrah K, Deutsch L.Department of Internal Medicine, McGill University, Montreal, Quebec,
Canada.
To assess the effects of krill oil on blood lipids, specifically total
cholesterol, triglycerides, low-density lipoprotein (LDL), and
high-density lipoprotein (HDL), a multi-center, three-month, randomized
study was done followed by a three-month, controlled follow-up of patients
treated with 1 gram and 1.5 g krill oil daily. Patients with high blood
lipids levels able to maintain a healthy diet and with blood cholesterol
levels between 194 and 348 mg per dL were eligible for enrollment in the
trial. A sample size of 120 patients (30 patients per group) was randomly
assigned to one of four groups. Group A received krill oil at a body mass
index (BMI)-dependent daily dosage of 2-3 g daily. Patients in Group B
were given 1-1.5 g krill oil daily, and Group C was given fish oil
containing 180 mg eicosapentaenoic acid (EPA) and 120 mg docosahexaenoic
acid (DHA) per gram of oil at a dose of 3 g daily. Group D was given a
placebo containing microcrystalline cellulose. The krill oil used in this
study was Neptune Krill Oil, provided by Neptune Technologies and
Bioresources, Laval, Quebec, Canada. The results showed Krill oil 1-3 g
per day to be effective in the reduction of glucose, total cholesterol,
triglycerides, LDL, and HDL, compared to both fish oil and placebo. It
appears that krill oil is effective for the management of high lipid
levels by reducing total cholesterol, LDL, and triglycerides, and
increasing HDL levels. At lower and equal doses, krill oil was
significantly more effective than fish oil for the reduction of glucose,
triglycerides, and LDL levels.
Krill Oil questions
Q. I much appreciate the low-key, un-pushy, approach of your
information. I also read Dr Mercola newsletters. He is a great fan of
krill oil but I chose to buy the krill product that you offer rather than
Mercola recommendation. I see that this morning the good doctor Mercola
rubbishes all krill oils but his own. This does tend to be a habit of his
and perhaps it is sometimes justified. I would be grateful if you could
read what he says and advise, since your product is implicated.
A. We take great effort to be as accurate as we can on the topics
we write about and the products that are listed on our web site. We try as
much as possible to not comment on information on other web sites unless
the information is potentially harmful to the consumer. As such, you may
wish to read the information on our web page on krill oil, and then decide
how you wish to proceed. If we come across additional krill oil research
that tests the differences between various brands, we will mention it. As
of September 2007, we have not seen research that compares the clinical benefit or
differences between various krill oil supplements on the market.
