What is Krill Oil?
Krill oil is a marine-based supplement harvested from tiny, shrimp-like creatures (zooplankton) found largely in the cold, pristine waters of Antarctica
Krill oil contains the same omega-3 fatty acids found in fish oil—plus a potent antioxidant called astaxanthin. This combination not only supports heart and brain function, but may also improve how effectively the body absorbs these critical nutrients.
And the more we learn about krill oil, the clearer it becomes that this small crustacean packs a big nutritional punch.
Krill Oil May Help With:
What To Look For In A Krill Oil Supplement
Even though omega 3s from krill oil are better absorbed than fish oil, you want to look for at least 100 mg of EPA+DHA per serving. Be careful to make sure that the dosage is actually for the fatty acids, as their concentration can vary in different types of krill oil.
Make sure the product you select is actually made in the USA, where we have strict manufacturing quality standards. In addition, you want a supplement that is third-party tested, by an independent laboratory. This will help ensure high quality and safety.
Try to choose a krill oil supplement that offers a 100% money-back guarantee. Look for brands that offer at least a 60-day money-back guarantee.
If you are not happy with your product, it should be easy to return your supplement. Avoid brands that make it very difficult to return a product or get a refund.
What To Avoid
Avoid krill oil supplements that contain unnecessary additives, fillers, or artificial ingredients. These can dilute the potency of the supplement and may cause adverse reactions in some individuals.
Beware of any supplements that claim their product treats or cures any specific disease or ailment, or promises miraculous, unrealistic, or misleading results. Always speak to your doctor before starting a new supplement routine.
Selecting the cheapest rather than the best quality can potentially do you more harm than good. If brands don’t identify certain ingredients or nutrients and their amounts in each dose, you could end up with an ineffective or potentially harmful supplement.

OVERALL GRADE
PROS
- Third-party tested.
- Simple & clean formula.
- High in astaxanthin.
CONS
- Only 60 mg omega 3s per softgel (need to take 2).
- Large, difficulat to swallow softgels.
Carlyle Krill Oil is another popular choice in the market.
It boasts a simple, clean formula that is third-party tested, and it’s notably high in astaxanthin—an appealing feature for those seeking extra antioxidant support.
