Omega 3 Review - 13 Things You Need to Know


Dietary supplements either work or they don’t. Period. Let’s find out which one Omega 3 is. We decided to take a closer look at all the ingredients, side effects, customer service, and clinical research to see what we could figure out. We dug deeper into reviews to see what people actually thought and experienced. Then, to make things easier for you, we refined and condensed it all to give you the bottom line.

What is Omega 3?


Omega 3 is a class of polyunsaturated fatty acids. Three types of omega three are thought to have significant health benefits [1]:

  • ALA as found in plant oils
  • EPA as found in marine algae and fish
  • DHA as also found in marine algae and fish

As a substance most commonly available through fish, studies have demonstrated that omega 3 has been a dominant staple of nutrition throughout human history.

Current diets in the West have become less dependent on fish products for nutrition than any in the past have ever been (and also less dependent on fish products than any current diets in the East, generally speaking).

As such, many nutrition experts postulate that most Westerners lack in the necessary amounts of omega 3 in their diets. [2]

Because EPA omega 3 is thought of as the most important and possibly the most lacking in Western diets, fish oil has become a very popular supplement.

Fish oil tablets are produced with the intention of offering all the omega 3 benefits without necessitating an increase in fish or seafood consumption.


Omega-3 Health Benefits

Claimed Omega 3 Benefits

As mentioned above, the purported benefits of omega 3 fish oil are very diverse.

When evaluated scientifically, a wide range of reliability for such claimed benefits exists. [3]

We will evaluate some of these claims later. For now, here is a list of supposed omega-3 health benefits:

Claimed Benefits of Omega 3 Fats for Heart and Lung Health

  • Reduces coronary plaque buildup
  • Excellent source of vitamin D
  • Regulates blood pressure
  • Improves blood viscosity
  • Encourages weight loss
  • Improves breathing for asthmatics

Claimed Benefits of Omega 3 Fats for Various Other Diseases and Disorders

  • Relieves pain caused by rheumatoid arthritis
  • Helps in the treatment of lupus
  • Lessens inflammation for cystic fibrosis patients
  • Helps both macrovascular and microvascular functioning for those suffering from type 2 diabetes
  • Useful in treating chronic dry eye syndrome

Claimed Benefits of Omega 3 Fats for Mental and Emotional Wellbeing

  • Enhances memory and cognition
  • Slows down memory loss in the elderly
  • Treats postpartum depression
  • Improves attention, emotional states, and behavioral issues in ADD and ADHD patients

Additional Omega 3 Health Benefits

A list such as the one provided above may make omega 3 look like a wonder drug that cures diseases, removes pain and heals discomfort.

Naturally, omega-3 fatty acid facts tell a different story.

While many benefits are widely supported by scientific research, it should not be used as a catch-all for any diagnosis.

The different types of omega 3 listed in the first section above have different benefits that we much separate from each other.

The means of intake (whether as a food source or supplement) may create a distinction in the levels of results.

That is, fish oil capsules benefits may differ from omega 3 food benefits. [4]

Scientific research conducted on ALA omega 3, that which is found predominantly in plant oils, has suggested that ALA omega 3 most likely offers the following benefits:

  • Lowering blood pressure
  • Preventing coronary plaque buildup
  • Decreasing risk of heart disease

However, several limitations are also associated with ALA omega 3 research.

Problems associated with ALA omega 3 deficiency are also commonly associated with excess of omega 6 fatty acids, making distinctions between the two difficult. [5]

Many studies have been conducted regarding the relationship between ALA omega 3 and cancer, though little correlation (either positive or negative) has been established. [6]

EPA and DHA benefits are usually connected, as both are sources found in fish products.

Becuase these are more commonly lacking in Western diets than ALA omega-3 fats are, looking for the best fish oil supplement means looking for omega 3 fatty acid capsules or tablets that have the same characteristics found in food sources of EPA and DHA.

Hormonal regulation that is likely to improve immune system functioning, mood, and cognition.

May provide protection from heart and lung diseases as well as inflammatory disorders.

May lessen pain for patients with disorders associated with chronic pain. [7]

Unlike research into ALA omega 3, the omega-3 fats occurring in EPA and DHA food sources are better reflected in a supplemental omega 3 fish oil dosage.

Omega 3 Benefits and Results

Having looked through much of the research available regarding omega 3, we can determine that it is a necessary part of all diets.

The forms of omega 3 most missing in Western diets are found in fish sources that are not the most sustainable, making it difficult for people in many parts of the U.S. to get an appropriate level of marine types of omega 3 in their naturally occurring forms.

Supplements are therefore necessary to gain the diverse health benefits that omega 3 fatty acids supply.

Many, but not all, of the benefits, well-accepted health benefits of omega 3 are found within supplemental products.

However, no two omega 3 supplements are the same, so the first step in determining which supplement to take is to know what you need it for and which supplement(s) meets that need the best.

We hope that this can be your ultimate guide to omega-3 knowledge that can empower you to make the best decision of a supplement that works great for you.

Benefits of Omega 3 Foods

The benefits of omega 3 supplements are designed to mimic those benefits occurring naturally in fish.

We looked at three broad areas of health benefits where this match occurs.

While certainly not a wonder drug as some long lists of purported omega 3 benefits tend to suggest, scientific research does support the ideas that Omega 3 is a necessary dietary material that is not sufficiently received in the U.S. and other parts of the West.

Its positive effects are broad enough to boost health in many areas.
Heart and lung health are the most studied and best-attested benefits of omega 3.

The EPA and DHA types of omega 3 are most missing in Western diets.

EPA and DHA omega 3 supplements tend to have similar positive effects as their counterparts that occur naturally in fish and seafood.

Benefits of Fish Oil Capsules

In addition to their potentials for helping to regulate breathing for asthmatics and helping boost general lung health, some current research suggests that supplements of the EPA and DHA forms of omega 3 can be valuable as part of the treatment for COPD symptoms.

Finding the best fish oil tablets or capsules for COPD patients, however, must always be accomplished as secondary to the doctor’s prescribed drug regimen and any suggested lifestyle changes (especially the cessation of smoking where applicable). [8]

Similarly, the anti-inflammatory effects of the EPA and DHA types of omega 3 are well mimicked by fish oil supplements to be part of the treatment for related diseases.

Again, as a secondary type of treatment to all doctor’s orders, beginning with an appropriate omega 3 fish oil dosage daily may help to remedy many inflammatory symptoms of such diseases, especially cystic fibrosis. [9]

Connections have been sought between omega 3 and treatment of psychological disorders.

While little evidence has shown any direct connection, omega 3 can help though not necessarily with the psychological disorder per se.

Rather, they can help to decrease the adverse side effects of several psychotropic medications [10]

Why You Need Omega 3

As we have looked at the impact omega 3 has on the body and the negative effects of the large degree of deficiency of that material in the West, we can determine that everyone’s body indeed needs omega 3.

Forms that occur in plants and fish are both necessary for different purposes.

The latter, however, is more commonly missing from many Western diets so supplements can be helpful to create those same positive health effects found in fish and seafood.

Therefore, the reasons why you need omega 3 are many:
as central nervous system mediators to work with antioxidants towards healthy functioning of the immune system to protect the body and mind from some of the more damaging potential risks of stress to slow down cognitive effects of aging
to support heart and lung health. [11]

Omega 3 Weight Loss

One important study has shown that either the use of omega 3 supplements during attempts for weight loss appear to connect with a decrease in appetite, thus helping in the attempt to lose weight. [11]

Nevertheless, this is only one test that has not yet been well corroborated. So much more research into this connection is necessary before any clear conclusions can be drawn regarding this perceived connection between omega 3 and decreased appetite.

On the other hand, many studies have agreed, showing that people trying to lose weight who increase their intake of fish and seafood are more likely to lose weight than those following an otherwise similar diet without the increase of naturally occurring omega 3. [12]

As such, we must recognize that not enough data exists yet to know if weight loss is one of the factors where omega 3 supplements effectively mimic the effects known to occur naturally in fish and seafood.

Until further data is found, therefore, naturally occurring omega 3 is a better choice for people trying to lose weight.

Does Omega 3 Work?

While omega 3 might not quite accomplish all the things some have touted its ability to do, it is indeed likely to be effective in many of the areas we have already looked at.

Therefore, the answer to the question “does omega 3 work?” is simply not answerable without a specific purpose that one wants it to work for.

Omega 3 Side Effects

Commonly reported omega 3 side effects are as follows [13]:

  • Bad breath
  • Nausea
  • Bowel irregularities
  • Increased risk of bleeding

The Companies behind Omega 3

Omega 3 is a popular supplement available in many forms by many different companies.

Medical experts claim that EPA omega 3 in undeniably beneficial in many areas of health, but especially in regards to cardiovascular wellbeing.

They are not certain, however, as to how well omega 3 supplements mimic the actions of the omega 3 that occurs naturally in fish and seafood. [14]

Because of this, consumers must recognize that not all omega 3 supplements are equal.

The type of omega 3 and the way in which it is processed determine which benefits are most likely to occur in a given supplement.

This means, therefore, that an individual must decide which benefits he or she is looking for and match those needs up with the benefits thought to exist in a particular omega 3 supplements.

Then, he or she can begin to determine which is the best source of omega 3 fish oil for him or her.

Practically every company that manufactures dietary supplements offers fish oil tablets or another omega 3 fatty acid capsules.

Each one varies, meaning that different companies produce omega 3 supplements with differing benefits and purposes.

Thus, it is necessary for individuals to learn how those differences interact with their own needs to choose what will be the best fish oil supplement for that person’s health.

Where to Buy Omega 3 and How Much It Costs

Almost every company that produces dietary supplements sells at least one type of omega 3 supplements.

This means that each company produces the product to emphasize particular effects of omega 3 with slightly differing concentrations.

Remember, there are no two omega 3 products are equal. As a result, costs may vary. So the most important factor is how you answer the question, “What do I want omega 3 to do for me?”

Once you have answered that question, you can weigh through different omega 3 products to see which one is best for you.

Discussions with doctors and nutritionists can be invaluable in this process to ensure that the product you purchase helps to meet your individual needs.

Omega 3 Directions

Again, directions may vary, but the consensus is that a daily dosage of an omega 3 supplement should not be greater than 3 mg per day.

Prescription forms of omega 3 are available at higher doses, and thus nothing less than 3 mg per day is advisable unless otherwise recommended by a medical professional. [15]

Alternatives to Omega 3

Attempts at genetically engineering the oils associated with omega 3 fish oil have begun, and are thought to be progressing successfully.

This is being done to help protect populations of fish in areas where over-fishing has occurred. This appears to be a promising alternative eventually.

But, there is still much more work to do in this process before it can be determined successful. [16]

“”I don’t care for the lemon oil in the product. Personal preference only. Quality was good and fast shipping.””

The Bottom Line – Does Omega 3 Work?

What’s the real deal with Omega 3? Some supplements of high quality may help support overall health, but may not affect weight-loss the same way clinically tested appetite suppressants and fat burners would. For this reason, we are hesitant to give the green light.

What You Should Know

Omega 3 is a kind of fish oil supplement that claims to improve the health of men and women if taken daily. These capsules are claimed to be beneficial in regards to memory, anti-aging, prostate health, reducing the likelihood of stokes, cardiovascular health and joint pain. Furthermore, Omega 3 supplements are claimed to assist with the weight loss process. This involves the "oxidation of fat," which can potentially decrease the user's body fat. Omega 3 supplements are meant to be taken three times each day with water and they come in a simple capsule form. The Omega 3 supplements are stated to be free of contaminants, heavy metals and toxins that may harm the user. Basically Omega 3 oil capsules come from "healthy" wild fish. The official website talks about how many individuals are "deprived" of these essential fatty fish oils and therefore need some form of supplement to replenish their bodies. For those who wish to lose excess body weight, it's wise to take Omega 3 supplements in conjunction with a healthy diet and fitness regimen.

List of Ingredients

Some key components of Omega 3 supplements are DHA (480 mg), EPA (460 mg), DPA (50 mg) and mixed omega 3s (80 mg). These include ETA 3, SDA, ETA, ALA and HPA. These are known as the eight Omega 3 "family members."

Product Features

Omega 3 capsules (salmon oil) are basically fish oil supplements that endeavor to improve health and assist with weight loss on some level. These supplements are geared toward both men and women. Omega 3 capsules are to be taken three times daily in order to assist with memory, anti-aging, prostate health, reducing the likelihood of stokes, cardiovascular health and joint pain. A bottle of 90 capsules sells for $32.50 via the official website. Primary ingredients found in Omega 3 supplements are DHA (480 mg), EPA (460 mg), DPA (50 mg) and mixed omega 3s (80 mg). Additional components of Omega 3 capsules are glycerin, gelatin and water.


  • Omega 3 supplements can be purchased easily and conveniently through the official website or at most drugstores.
  • Omega 3 capsules are claimed to be seriously tested for heavy metals and toxins.
  • Omega 3 supplements come in an easy-to-take capsule form.


  • The consumption of three Omega 3 supplements daily may prove to be a tad irksome for some individuals.
  • Omega 3 supplements do not appear to be sold with a money-back guarantee.
  • Some vegetarians may not care to take a product that's derived from fish.
  • Some individuals may be allergic to certain components of Omega 3 supplements.
  • There doesn't appear to be consumer testimonials regarding weight loss on the official website.


Most people tend to feel pretty good about consuming fish. It's actually thought of as one of the healthier meats available. However, this doesn't mean that Omega 3 fish oil products will successfully help individuals lose unwanted weight. It's important to remember that this is claimed to be more likely if a balanced diet and regular exercise are part of your daily routine. Furthermore, there are certainly numerous weight loss supplements on the market to consider. It looks to us like Omega 3 capsules are more of an all-purpose health supplement than a targeted weight loss product.
