Buyers Guide Information

I know you were looking for what are the best options, but here is some more detail as to why we might need good krill oil products to help us get a good source of omega 3 fatty acids.

Benefits of Taking Krill Oil

Krill oil, like fish oil, contains the omega-3 fatty acids DHA and EPA, which have important functions in the body.

Krill oil is sometimes considered better than fish oil because it contains omega-3 fats in a more digestible form. In addition, krill is more sustainable because the tiny shrimp-like fish is abundant in the ocean and reproduces more rapidly than most fish. (ref)

Here are some of the benefits of taking krill oil:

  • Easier than fish oil to absorb
  • Tastes better than fish oil
  • Fights inflammation
  • Fights free radicals
  • Keeps skin healthy
  • Improves brain function
  • Reduces joint pain and arthritis
  • Improves heart health
  • Helps with premenstrual syndrome symptoms
  • Is environmentally sustainable

Recommended Krill Oil Dosages to Take

Since krill oil absorbs more efficiently than fish oil, you only need to take about two-thirds the amount of krill oil as you would fish oil. If you normally take 1,000 milligrams of fish oil, than about 660 milligrams of krill oil should be sufficient. However, in clinical trials dosage usually ranges from 1,000 to 3,000 milligrams, so it appears to be safe in larger amounts. (ref)

Possible Side Effects

Side effects of krill oil are similar to those of fish oil. You should not take krill oil if you are pregnant, breastfeeding or obese, or if you have a seafood allergy, diabetes, a bleeding disorder or have recently had surgery. This is not necessarily because you will have an adverse reaction, but because there have not been enough studies concerning how a krill oil supplement will affect these conditions. (ref)

In addition, check with your doctor if you are taking any medications, as there may be issues with certain drug interactions. (ref)

While krill oil is generally considered safe for most adults, here is a list of possible side effects:

  • Stomachache
  • Nausea
  • Diarrhea
  • Decreased appetite
  • Heartburn
  • Taste change
  • Fishy burps
  • Gas and bloating
  • Oily facial skin and breakouts
  • In rare cases, high blood pressure
