Omega-3s

Each serving of two soft gels gives the consumer 2,000 mg of total Omega-3s that includes 1400mg of EPA and 480 mg of DHA. It also features another 120 mg of other Omega-3’s.

Other Ingredients

This option contains fish oil from anchovy, sardine and mackerel. The soft gel capsule contains halal bovine (beef) gelatin, glycerin, purified water and Vitamin E. It does not have corn, egg, milk, wheat, peanut, tree nut, or artificial colors or sweeteners. It has 20 calories per serving, with 2 g of fat.

How It’s Sourced

This brand uses an unique method called supercritical extraction to concentrate the Omega-3s that differs from being molecularly distilled. Instead, this is a heat-free and chemical-free carbon dioxide extraction that both refines the oil and gets rid of any contaminates. This method helps to ensure the fish oil is highly concentrated, triple that of many brands. The fish oil is from sustainably-harvested fish from Peru.

Taste

The soft gels do not feature an enteric coating to prevent a fishy taste, but because of the fish oil’s extraction process, there is a little fishy taste and odor, as well as minimal fish burps.

Absorption

Viva Naturals’ capsules are in triglyceride form, which helps to absorb the Omega-3s faster. This supplement also contains other natural fish fats and oils that boost absorption of the Omega-3s in the body.
Pros

It seems simple enough just to take a daily dose of an omega-3 supplement, but choosing the right one is important.  It’s first important to define exactly what omega-3s are. Omega-3s are fatty acids that are needed for the body to function healthfully. The three main omega-3s are eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA). EPA and DHA are found in fatty fish, whereas ALA is found in vegetable oil, nuts, flax seeds, leafy greens and some animal fats. Some omega-3 supplements contain all three omega-3s, but some do not contain ALA.

The Criteria We Used to Find the Best Omega-3 Supplements

There are countless brands that sell supplements with omega-3s. We did all the heavy duty research to make sure that consumers are given a list that narrows down their choices when looking to buy. Each of the key factors in creating our list of the best omega-3 supplements are listed below.

Potency
How many mg of omega-3s does this supplement have? Omega-3s include DHA, EPA and ALA, so it’s important to consider how the percentages are broken down.

Safety
Since these supplements are often from fish oil, it’s important to make sure they do not contain heavy metals like mercury and PCBs to ensure safety for consumption. There are also options that contain no artificial colors, or is gluten-free for those with allergies.

Effectiveness
How well the body absorbs the omega-3s is crucial to see benefits. Omega-3 supplements come in two forms: triglyceride (TG) or ethyl ester (EE) form. The form also may play in role in how the omega-3s are absorbed into the body.

Value
Where is the fish oil sourced from? Is it coming from farm-raised or wild fish? Is the product made in the U.S? Does it have any certifications to back up its safety and quality?

Other Important Factors To Consider When Selecting The Best Omega-3 Supplements

 

Health Benefits

There are many health benefits associated with taking omega-3 or fish oil supplements. Although it has been debated as to how much they actually impact heart health, the supplements can lower triglyceride and cholesterol levels. As a result, this lowers the risk of heart disease. Omega-3s also have anti-inflammatory properties which help relieve arthritis and other joint pain. It can also improve lung function to ease asthma symptoms.

Expectant mothers have probably heard how crucial DHA is for their unborn babies and infants, as this aids in brain development. There have even been studied linking fish oil to reducing ADHD symptoms. Studies have also suggested the supplement can help boost mood and fight depression and anxiety. This is because fish oil supports serotonin, or the “feel good” hormone, which can reduce stress.

TG vs. EE

There is some back and forth as to which form enables DHA and EPA to be better absorbed, and which is overall safer. Some research suggests that EE (ethyl ester) fish oils go bad faster, and aren’t absorbed as easily into your body. One study found that TG (triglycerides) omega-3s are better absorbed in the body and that they are better bioavailability. Interestingly, EE forms of omega-3 supplements are most commonly used in clinical trials for heart health.

Other studies suggest that the differences in efficacy and safety are so minimal between the two forms. When it comes down to it, there is no clear answer to which one is more superior.

FAQ

Q: What is the recommended daily dosage of omega-3s?

A: Researchers recommend at least 500 mg of EPA plus DHA for healthy individuals, or at least 800 to 1,00 mg for those with heart disease. Pregnant women should take at least 300 mg of DHA daily.

Q. What are fish burps?

A: Fish oil can be hard to digest. As a result, gas can be created as the body breaks it down. Than then causes burps that have a fishy odor, which is commonly called “fish burps.” Fish burps can also be caused by impurities or oil that is not fresh since this can trigger intestinal issues.

Q: What are common side effects to taking omega-3s?

A: One of the most common side effects is fish burps, which can be prevented by lower the dosage, buying one with an enteric coating, or placing the supplement in the freezer which will decrease how fast it is broken down in the stomach. Other stomach discomfort is another common side effect.

Q: How large are omega-3 capsules?

A: The size of the pill varies with each brand, but they are generally a standard size that is much larger than a typical aspirin, but not too big to swallow. Many brands offer soft gel capsules that help make swallowing easier.

Q: Who should take fish oil supplements?

A: Healthy adults and even children can receive benefits from taking fish oil supplements. It’s a good idea to take for those with heart issues, but as with any supplement consult with a physician first. Pregnant and nursing women should also take DHA supplements, an omega-3 that is found in fish oil.

Q: What is the difference between omega-3 supplements and fish oil supplements?

A: Fish oil is the source of omega-3s that include EPA and DHA. Essentially they are one in the same, although some omega-3 supplements include other vitamins.
