Krill Oil or Fish Oil? or “The Krill Is Gone, baby”

Written by  //  January 8, 2012  //  Good Stuff You Gotta Know!, Supplements  //  2 Comments

My daughter Laura asked me about Krill Oil.

“Which is better for you, Krill Oil or Fish Oil?”

To answer this question, I looked for  unbiased studies and articles from non-invested contributors.  What I found out is quite interesting.  In the end, only you will be able to answer this question for yourself, but at least you will have solid information to base the decision on.

First and foremost, if you have any allergies to seafood or in particular shrimp, I would certainly consult a physician before taking this supplement.

Krill is a shrimp like creature present in the pristine waters of the Antarctic in abundance.  Yes, and before you ask me, it is what whales eat.  These waters are clean and free of impurities making mercury a non issue for eating Krill.

In a study listed in the American Journal of Medicine comparing the effectiveness of Krill Oil vs. Fish Oil using Krill from Neptune Krill Oil, the Krill was determined to be more effective. and
from The Department of Internal Medicine, McGill University, Montreal, Quebec, Canada.

The question is how much more and why?

Krill Oil like Fish Oil and I am referring to the intake of DHA and EPA (see my article previously on Omega 3) is a rich source of Omega 3, but Krill Oil offers two other benefits.



One is that Krill is a phosolipid.  Like our own body, this makes the oils in Krill easier for us to absorb.Also, and here is the biggie, Krill Oil is very rich in Astaxanthin.A marvelous and very effective antioxidant.

So Krill’s health benefits include protecting our cardiovascular system, joint health, helps to increase in memory,  aid in anti aging and lessens PMS.  Much like our Omega 3.

So, no brainer you say.  Not so fast.

First, Krill Oil is very expensive, much more so than Omega 3’s.  But the kicker is that it doesn’t contain as much DHA and EPA as fish oil does.  Actually, Krill contains considerably less.  So you are paying more, but still not getting the amount of DHA and EPA you need.  So, you would still need more.  Now, you could also take fish oil in conjunction with the Krill, if that is the route you decided to take.  However, you can buy Astaxantin separately.  Almost all health food stores have it.  The benefits of this super antioxidant are fantastic.  That way you would kind of have the best of both.

The recommended dose for Astaxanthin is 2-4 mg a day depending on your size and stature.

As always, the choice is yours to make.

    Hi Admin,
    Maybe a little off topic, however, Krill oil is extracted naturally from Krill, tiny shrimp-like crustaceans that are about 1 to 6 cm long, living in unspoiled natural waters of the Antarctic Ocean and sold as nutritional supplement in food stores and online. The extract contains many nutrients like omega- 3 fatty acids, astaxanthin, antioxidants required in all living bodies for central nervous system, eye, brain and overall wellness. The astaxanthin is a superior form of anti-oxidant that crosses the obstacles of blood- brain for maintenance and growth of vital human organs. These marine invertebrates are rich in essential fatty acids with Omega-3, Omega 6 and Omega 9 and also with the essential phospholipids required for block building in cell membranes. This oil has many other benefits-it is free from heavy metals harmful to human body. In many ways it is superior to common fish capsules.

    I think the biggest question we should all be asking is that of sustainability. Krill are what whales eat, and they are the beginning of the oceanic food chain. What happens when we overharvest for profit? We should all by now be aware of the results of overfishing, this is just a new form of marketing, a way to bring something “new and exciting” to the table that doesn’t really provide any exceptional benefits.
