As a kid, I was always preached to about the benefits of fish oil. And I’ve pretty much taken it since I was about eight years old.
But in recent years, I’ve decided to take krill oil supplements more often.
Why?
On the one hand, it’s for environmental and sustainability reasons. But there is also plenty of evidence that it’s a safer source of omega-3 fatty acids because of lower levels of heavy metals.
Basically, fewer risks of side effects.
So, we went and researched some of the most popular and best krill oil supplements available.

Krill Oil Buyer’s Guide
Before you just start taking krill oil capsules, I would suggest that you follow these three tips that we used in our best krill oil supplements research.
1 - Compare Based On Dose
Depending on whether you’re a high-performance athlete, or just want the general health benefit from omega-3 fatty acid, it’s important to start with your krill oil intake per day. It also applies to fish oil products.
For most men and women, a 1,000 mg capsule will be a good starting point [1].
So it’s important to then look at the serving size on each product to better compare the price.
Bonus tip: try to get a product that has two capsules per serving; this may allow easier dose increases.
2 - Source And Purity
Pretty much every krill oil supplement we saw is sourced from Antarctic waters, where krill seems to be most abundant. But the other advantage is that it should reduce the risks of heavy metals exposure and associated side effects [2].
Because they are at the base of the food chain, krill do not accumulate as many potentially harmful toxins and heavy metals as other marine life higher in the food chain.
- Dennis A. Goodman, MD
Next, you want to make sure that the omega-3 fatty acids are purified without the use of chemicals. This should increase the quality of the DHA and EPA in the products, which could make it easier to absorb into your blood-stream.
3 - Avoiding Fishy Burps
While there are many benefits of krill oil supplements, including lower cholesterol and increased brain function [3], you may need to factor in the fishy burps.
This is very much the same as with fish oil supplements. But there are some products that manage to create capsules that release the omega-3 fatty acids more slowly.
It also generally should help to take them just before a meal.
FAQs
What Is Krill Oil Good For?
Krill oil is good for your cardiovascular health as well as brain function. It has been shown to improve heart health and blood pressure by reducing the effects of harmful cholesterol levels in the blood.
Is Krill Oil Bad for Your Liver?
No, krill oil isn’t bad for your liver at a normal daily dosage unless you have other underlying liver problems. Krill oil, like fish oil supplements, increase your body’s fat intake, but at low doses, this shouldn’t affect fat retention in liver cells.
