Benefits of Krill Oil vs. Fish Oil

Both krill oil and fish oil may offer health benefits in preventing, managing, and treating heart disease, high triglyceride levels, diabetes, and more. They're both good sources for EPA and DHA, two of the most well-researched omega-3 fatty acids.

Research shows that krill oil is more readily absorbed by the body and contains more antioxidants, whereas fish oil is cheaper, more portable, and higher in omega-3s. Further studies are needed to determine which oil is more beneficial for the human body VSports app下载. .

V体育官网入口 - Krill Oil vs. Fish Oil Benefits

While krill oil is often considered an alternative to fish oil, there are several key differences between the two VSports手机版. Some general differences are krill oil supplements have a reddish hue and come from a small, shrimp-like crustacean, while fish oil supplements are yellow or gold and come from fatty fish. .

In addition, some manufacturers and consumers claim krill oil is more palatable than fish oil and does not produce a fishy aftertaste. V体育安卓版.

Krill Oil May Absorb Better (V体育官网)

The fatty acids in fish oil are found in triglycerides, while the fatty acids in krill oil are found in phospholipids, which may help increase the absorption of krill oil V体育ios版. .

However, a recent study found the total absorption of fatty acids from krill and fish oils was similar, but the absorption rate was faster with fish oil VSports最新版本. Another study found bioavailability of fatty acids was similar for krill and fish oil when they were matched for dose, EPA, and DHA concentrations. .

Further studies are needed to determine if one is absorbed better than the other V体育平台登录. .

Fish Oil Is Cheaper and More Accessible

Fish oil is generally cheaper and easier to find in stores than krill oil. A cost analysis of common products indicated that fish oil supplements range from 1 to 15 cents while krill oil is approximately 30 cents per 100 milligrams (mg) of EPA+DHA. VSports注册入口.

Krill oil is more expensive partially due to the need for immediate processing once the krill is harvested to prevent spoilage V体育官网入口. In addition, fish oil can be sourced from various fish species, making it more affordable due to the broader availability of fish. .

"VSports最新版本" Krill Oil Contains More Antioxidants

Although omega-3 fatty acids have antioxidant properties, krill oil also contains the antioxidant astaxanthin. This antioxidant may help reduce oxidative stress, which is associated with neurological conditions, cardiovascular disease, inflammatory conditions, and more VSports在线直播. .

Fish Oil Has More Research into Benefits

Fish oil has more research to support its health benefits than krill oil. Primarily due to the lack of research on krill oil, the health benefits evidence is inconclusive.

"VSports手机版" Fish Oil Has More Omega-3 Fatty Acids

Although krill and fish oils are both sources of omega-3 fatty acids, fish oil typically contains more omega-3 fatty acids per serving than krill oil.

The omega-3 content of krill and fish oil varies considerably between supplements. However, the dose of EPA and DHA in krill oil supplements generally ranges from 45 to 200 mg per soft gel. In contrast, the amount of EPA and DHA in fish oil products ranges from 300 to 2,200 mg per soft gel or teaspoon.

Omega-3 fatty acids may reduce the risk of heart disease, lower levels of inflammation in the body, and support fetal development and healthy aging.

A review and meta-analysis looked at the impact of omega-3 supplementation on maternal health and fetal growth. The study authors concluded that omega-3 supplementation during pregnancy can prevent preeclampsia, increase birth weight, and decrease the risk of low birth weight and preterm birth.

Studies show that eating omega-3-rich fatty fish and seafood is associated with a lower risk of several chronic diseases, including heart disease. However, it is unclear whether these benefits come from simply eating these foods or their omega-3 content.

A decent amount of evidence suggests omega-3 supplementation may be effective at reducing levels of triglycerides (a type of fat in the blood) and alleviating symptoms of rheumatoid arthritis. One study found that krill oil significantly lowers triglyceride levels in patients with high triglycerides (hypertriglyceridemia).

In another study, researchers found krill oil was slightly more effective than fish oil at lowering triglyceride levels. The reduction in triglycerides depends on the dose of omega-3s rather than the type of oil consumed.

In food or supplement form, EPA and DHA omega-3s may reduce the risk of coronary heart disease by lowering high blood pressure, specifically among people who already have hypertension.

"VSports手机版" Krill Oil vs. Fish Oil Side Effects

Omega-3 supplements, including fish and krill oils, are generally considered safe when taken in recommended doses, but there are some fish oil side effects.

If you are allergic to fish or shellfish, you should avoid taking fish oil or krill oil supplements until you speak with your healthcare provider.

Fish oil or krill oil may have blood-thinning effects at high doses and can interact with certain medications, such as Jantoven (warfarin). Some experts say greater than 3000 milligrams of omega-3 fatty acids with warfarin could increase bleeding time. However, a retrospective study found chronic high doses of omega-3 fish oil supplements didn't significantly affect bleeding time or increase the risk of adverse events. 

Krill Oil

Krill oil is a safe alternative to fish oil, with no significant reported side effects. Krill also do not contain unsafe accumulations of mercury because they are low on the ocean's food chain.

Manufacturers of krill oil often claim that it does not cause a fishy aftertaste, fish burps, or reflux, all of which are common side effects of fish oil supplements. However, some individuals may still experience these side effects.

Fish Oil

Side effects that are reported are usually mild, consisting of:

• Bad breath
• Heartburn
• Nausea
• Stomach discomfort
• Headache
• Foul-smelling sweat
• Diarrhea
  

"V体育2025版" Dosage of Krill Oil vs. Fish Oil

Experts recommend consuming 6–8 ounces (about two servings) of fish per week. This increases to 8 to 12 ounces of fish and seafood per week during pregnancy and breastfeeding to support the health of your developing baby. Four ounces of Atlantic salmon provide around 3 grams of omega-3 fatty acids.

However, consuming high doses of more than 900 mg of EPA plus 600 mg of DHA daily for several weeks may reduce immune function by suppressing the body's inflammatory responses.

It is important to choose fish low in mercury and high in EPA and DHA during pregnancy. Fish high in mercury include:

• King mackerel
• Marlin
• Shark
• Swordfish

Fish low in mercury include:

• Canned light tuna
• Salmon
• Sardines
• Herring

Fish oil supplements are purified of environmental toxins like mercury. There is no established recommended dosage for krill or fish oil supplements, but the Office of Dietary Supplements recommends not exceeding 2 grams of EPA and DHA a day from dietary supplements.

Who Should Not Take Krill or Fish Oil?

Talk with your healthcare provider before taking krill or fish oil if you:

• Have a bleeding disorder
• Have a seafood allergy
• Have an upcoming surgery
• Are pregnant or nursing

A recent study found that fish oil supplements are beneficial to people who already have cardiovascular disease (CVD) but advises against taking fish oil supplements if you are healthy. The researchers found regular use of fish oil supplements might be a risk factor for atrial fibrillation and stroke in the general population.

These risks are not associated with food sources containing omega-3 fatty acids, so it may be best to stick with food sources instead of supplements if you don't have CVD.

"VSports注册入口" Alternative Omega-3 Sources

Omega-3s are widely available in a variety of different plant foods. Plant-based omega-3s from algal oil typically provide about 100–300 mg of DHA, with some containing EPA. The omega-3s are generally present in the triglyceride form. The bioavailability of DHA from algae oil is similar to that from cooked salmon.

Vegan foods with omega-3s include:

• Chia seeds
• Flaxseed
• Seaweed
• Algae
• Hemp seeds
• Walnuts
  

Where to Find Krill and Fish Oils

You can purchase fish oil and krill oil online or from most drugstores. Krill oil may be a little more challenging to find in stores, but it can easily be bought online. Always check to ensure independent testers test the supplement for any contamination from harmful materials.
