Flaxseed Oil vs Fish Oil – See Which Omega 3 Supplement is Better

Which oil is better:

Flaxseed Oil or Fish Oil?

This is a very common question in current health topics.

They both contribute in maintaining a healthy body, however unless you are allergic to fish and/or, a strict vegetarian or vegan, greater benefits will come from consuming fish oil.

Here’s why!

Flaxseed oil and fish oil are both rich in omega 3 fatty acids, but in different forms.

Flaxseed oil contains the essential fatty acid, alpha-linolenic acid (ALA) which the body has to convert to docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), the same two fatty acids found in fish oil.

The body however, is not very effective in performing this conversion. It is often slow, difficult, and incomplete.

Many nutritionists advice fish oil over flaxseed oil because the body receives EPA and DHA directly without the need for this difficult conversion.

So following the experts recommendation; choose fish oil over flaxseed oil when selecting a supplement abundant in omega 3 fatty acids.

Flaxseed oil

Flaxseed oil, also known as linseed oil, is produced from a plant that blooms blue flowers and is valued for it’s tiny nutrient rich seeds.

It is recommended as an excellent source of omega 3, one of the essential fatty acids of polyunsaturated fats, which are required for optimum functioning of the body.

Additional flax seed oil benefits and nutrients include both omega 6 and omega 9 fatty acids, zinc, potassium, magnesium, protein, fiber, and lecithin.


Lecithin, for those of you who are unfamiliar with the term, is a basic classification for fatty substances that occur in plant tissues, animals, and animal products, such as eggs.

There are many health benefits of consuming lecithin, in fact many people take lecithin in the form of a supplement. As lecithin promotes fat transport and metabolism, it is often used by dieters and weight loss enthusiasts.

Adding flax seed to your diet will not only contribute towards a healthy body weight but additionally benefit many other body and brain functions.

Individuals who would like to benefit from omega 3 fatty acids but are not getting a adequate amount from natural food sources are often advised to incorporate supplements into their diets.

Flaxseed oil is sold in soft-gel capsules or liquid form.

Check the Expiration Date

Flaxseed oil is especially sensitive to light, heat, and oxygen and accordingly should be packaged and refrigerated.

Along with how flaxseed oil is produced, you can determine the quality of the product from the duration of time between manufacture and purchase date, as many products for sale are already over-stored.

Also inspect the packaging.

Make sure the oil is sealed tightly in dark bottles and both processed and stored at a low temperature. Similar to any oil, flaxseed oil will turn rancid if not stored properly and used within the expiration date.

Flaxseed oil is not alone in terms of producing numerous health benefits as well as nourishing the body in omega 3 fatty acids. Allow me to introduce the many fish oil benefits.

Fish oil Benefits

Fish oil, extracted from the tissues of oily cold water fish, is an extremely rich source of omega 3.

The benefits of fish oil are well established and numerous. Not only does fish oil contribute toward a healthy functioning body, but research shows it also helps prevent and treat various health conditions.

Adding fish oil to a balanced diet will not only allow one to reap the benefits of consuming a sufficient amount of omega 3s but potentially protect the body from unhealthy pollutants found in the tissues of fish.

Unlike whole fish, fish oil is often marked and processed to remove these poisons.

Buyer Beware

All fish oil sold in a supplement form is different, so it is very important to buy quality products to ensure you are receiving full health benefits and not consuming potentially harmful contaminants.

Fish oil, like flaxseed oil, is sold in both liquid and capsule form.

There are numerous factors to be aware of when purchasing fish oil.

Most importantly because of the accumulation of pollutants and heavy metals in fish, oil products derived from these sources must go through molecular distillation.

This process removes pollutants and poisons that are found the oceans around the world. These pollutants, both natural and man made, must be removed before consumption for health safety.

Therefore, check the label to confirm the fish oil product you are purchasing has gone through this molecular distillation process.

This is a very important factor in determining the product’s safety, however there are many other verifying characteristics.

Determining if a company is credible and dedicated to natural health is another important factor to verify the fish oil product is high quality.

Checking other reputable products the company also sells or a little background research will aid in this discovery.

Another way to verify the safety of a fish oil product is to confirm where the fish comes from.

This information may not always be available and if it is, it’s to promote the product is from safe waters.

Unfortunately, most the of the oceans on Earth are contaminated by various pollutants and poisons, however there are some cleaner oceans, such as the pristine waters surrounding New Zealand and the southern tip of Australia. It is always important to be a mindful consumer.

The following are fish and fish products that should be avoided:

Fish that swim in the Atlantic Ocean, such as Atlantic Halibut, are at risk because of the extreme levels of pollutants and heavy metal contamination found in this ocean.

  • Cod also swim in polluted waters thus have a high possibility of being contaminated. Also, methods used to catch these fish are not environmentally friendly as they destroy the habitats of other marine life.
  • Sharks have very high concentration of mercury because they are at the top of the food chain. Other large predatory fish, like the shark, should also be avoided because each time a fish eats another fish, mercury accumulates. Therefore the largest fish that rule the waters have very high levels of poisonous mercury.

This is not meant to deter individuals from consuming fish or using fish oil as an advantageous, healthy food source but simply to create an awareness of the potential risks associated with consuming poor products.

There are plenty of great supplements to choose from. Educating yourself is a crucial step toward finding a safe, optimal product.

This is also true of flaxseed oil products and all food sources.

It may take a bit of added research, but once you find a quality product, your search is over, and you can begin nourishing your body with omega rich oils.
