A reader recently asked me a question about fish oil. She wanted to know if krill oil is better for you than fish oil. Of course, the answer‘s never simple when it comes to your nutrition. So let‘s first start by discussing the ABCs of fish oil.
The catch-22 of fish oil
As you‘ll recall, omega-3 fatty acids (found in fish or cod liver oil) are basic building blocks of good health. In fact, that‘s why we call them "essential" fatty acids. These vital nutrients support your immune system, heart, mood, blood sugar, joints, brain, and so much more. But they also increase free radicals in your body.
Free radicals are charged molecules that can speed up the aging process. In addition, many scientists believe that free radicals can damage your DNA. They disrupt the natural life cycle of your cells, which over time can lead to diseases like cancer.
That‘s why I always remind you to take plenty of antioxidants (especially vitamin E and selenium). These antioxidants neutralize free radicals.
Finding the right fish oil
Our bodies need omega-3 fatty acids for survival, but we can‘t produce the essential omega-3 ourselves. So we‘ve got to get it from the foods we eat. Unfortunately, very few of us do.
In that case...
A bottle of high-quality fish oil capsules should always be a staple in your kitchen cabinet. Find a brand that you trust. Look for the bottle to say 99.99 percent purified fish oil.
But don‘t worry. The last .01 percent doesn‘t contain mercury. Just small impurities that are nearly impossible to refine away. (It‘s the same with gold. You‘ll only find 99.99 percent pure gold. There‘s no such thing as 100 percent pure gold.)
So if you can find good fish oil, what‘s the big deal about krill...?
The pros (and cons) of taking krill oil
As far as I can tell, there are four big reasons why people opt for krill instead of fish (or cod liver) oil.
First off, krill oil contains a decent dose of the antioxidant astaxanthin. So some natural medicine practitioners say you don‘t need the added vitamin E and seleni
