From The Manufacturer

PURE ANTARCTIC KRILL OIL Krill is a tiny organism harvested from icy cold waters of the Antarctic – far from industrial contamination. Their short lifespans, combined with the pristine environment from which they are harvested, ensure that krill have far less potential for toxins and contamination. SUSTAINABLY SOURCED The use of krill as a nutrient source is more sustainable than other types of fish oil, such as cod or salmon. Our supplier goes to great lengths to ensure only krill are caught and not other types of sea life. They’ve been certified by Friend of the Sea thanks to their commitment to being as sea-friendly as possible. OMEGA-3 POWERHOUSE Krill are extremely rich in omega-3s. Omega-3s are essential fatty acids utilized by multiple systems in your body. “Essential” means your body can’t produce them on its own, so you have to ingest them from food or a supplement. The pristine environment from which krill are harvested make them an ideal source of omega 3s. PRO RECOMMENDATIONS AJ HAWK “Onnit Krill Oil is something I make sure to take everyday.

An Overview On Krill Oil Pills

Fish oil has long been a preferred treatment for those who have moderate cholesterol issues. Just one dose a day can lower cholesterol and reduce the stickiness of blood platelets. But fish oil has its issues, including hard-to-swallow capsules and an unpleasant taste and odor.

In recent years, medical professionals have shifted their recommendations to krill oil, which some studies have shown to have better heart-health benefits than fish oil. You’ll also find that they have smaller capsules, making them easier to swallow, and low to nonexistent issues with smell and taste.

Like a shrimp, a krill is a crustacean found in the sea. Environmentally-conscious consumers prefer krill oil because krill have a shorter lifecycle than fish. Krill are also found in some of the most pristine waters of the ocean, which reduces worries about being exposed to oceanic toxins.

In addition to managing cholesterol, krill oil has also been linked to a reduction in inflammation, a benefit that is very valuable to those who suffer from chronic pain. Those suffering from conditions like arthritis and general joint pain have also reported improvement after starting a krill oil supplement. For some, premenstrual pain and mood symptoms have decreased while taking krill oil.

“Check with your doctor before starting krill oil supplements,” explains registered dietitian Jessica Cording, author of “The Little Book of Game-Changers: 50 Healthy Habits for Managing Stress & Anxiety.” “Because it has a blood-thinning effect, it may interact with certain medications such as anticoagulants. You also should avoid krill oil if you have a fish or shellfish allergy.”

Your doctor can also advise you whether you’re a good candidate for krill oil. If your cholesterol is extremely high, your physician will likely recommend a type of prescription medication called a Statin. Krill oil is better for being proactive about your heart health or trying to lower slight elevations.

As with many supplements, it’s best to get the benefits you need through food. To lower your cholesterol through your diet, fatty fish like salmon and mackerel will boost your good cholesterol and lower the type of cholesterol that’s considered bad. Other foods to incorporate into your daily meals include beans, avocados, nuts and grains. Just kicking off each day with a bowl of oatmeal can help get those numbers down.

Exercise can also help reduce your cholesterol. Whether you’re taking a krill oil supplement or not, try to find ways to work a little more exercise into your daily routine. Take the stairs instead of the elevator or start going for a short walk around the block after lunch. Soon you’ll start to see those numbers begin to drop.

The Krill Oil Buying Guide

  • When shopping for any supplement, it’s important to compare dosage. One bottle may be priced cheaper than others, but if you have to take two pills to get the same results with one of another type, you won’t be saving money. With the Sports Research Antarctic Krill Oil, 1000mg, you’ll get 1,000 milligrams in just one pill, but the capsules are much larger than what you’ll find in supplements that pack 1,000 milligrams in two pills. Bronson Antarctic Krill Oil, 1000mg provide 1,000 milligrams in two small capsules.

“Ideally you want to see a label indicating that product went through third-party testing to ensure quality and safety,” Cording says. “Store in a cool, dry place. Once opened, keep the container in the fridge.”

  • Sports Research Antarctic Krill Oil, 1000mg is certified by the Marine Stewardship Council, as well as being IKOS 5-star certified.
  • One of the biggest complaints about fish oil pills is the size of the capsules, making them hard for some to swallow. Bronson Antarctic Krill Oil, 1000mg are small in size and very easy to swallow. If larger capsules never bother you, though, you may want to consider the Sports Research Antarctic Krill Oil, 1000mg. It’s a larger pill, but you only have to take one to get the same dosage you’d get with two of the smaller-size supplements.
  • Digestion is also a consideration. Sports Research Antarctic Krill Oil, 1000mg is water dispersible, which means it digests more easily than fish oil even though the capsules are similar in size.
  • Often those taking supplements are concerned about what’s in the products they consume. Look for ingredients that are natural and soy and gluten-free, as well as being non-GMO. You may also want to consider a bottle that is free of egg, peanuts, tree nuts, fish, shellfish, corn, milk, soybean, wheat, sugar, chemicals and preservatives. Bronson Antarctic Krill Oil, 1000mg is soy-free and mostly natural, but it does have additives, including gelatin.
  • If you’re vegan, it’s important to note that krill oil comes from an animal, so it’s not safe for strict vegan diets.
  • Although krill oil reduces that fish taste that comes with taking fish oil pills, it’s important to note that you won’t get away from it completely. You may still experience a little of that taste when you burp. Sports Research Antarctic Krill Oil, 1000mg has both a fishy odor and slightly fishy burps. Although Bronson Antarctic Krill Oil, 1000mg doesn’t have a fish odor or taste, the smell is a little on the unpleasant side.
  • Most krill oil supplements fall within the same price range. However, if you’re closely monitoring your spending, look more closely at the price per dose than the overall cost of the bottle. Don’t forget to go by dosage rather than pill, as some supplements pack more milligrams into each pill than others.
  • One issue with Sports Research Antarctic Krill Oil, 1000mg is that it can tend to break inside the bottle if not handled delicately. If you plan to toss your supplement in a bag, this might not be the best option for you.
  • Krill oil should be taken with food whenever possible, and you should limit your consumption to the recommended daily dose.
  • For the most part, you shouldn’t experience side effects while taking krill oil. However, the same stomach upset sometimes seen with fish oil can apply, so if you have a decrease in appetite or stomach discomfort, that could be the cause. Other stomach-related side effects include gas, diarrhea and nausea.
  • Pay close attention to your complexion. You may have breakouts or slightly oilier skin after you start with a krill oil supplement.
  • As with any supplement, you should check with your doctor, but this is especially true if you’re pregnant or nursing. Since there isn’t enough information about the safety of krill oil, it’s best to err on the safe side and wait until you’re finished nursing to start taking it.
  • If you have surgery coming up, be sure to let your doctor know you’re taking krill oil. It could increase bleeding risks, so your physician will probably direct you to stop taking it at least two weeks before your scheduled operation.
  • Those who have seafood or shellfish allergies should skip krill oil.
