The Best Omega 3 Fish Oil: Our Picks

Guide: Questions you should ask yourself before buying an omega 3 fish oil

What are Omega 3 fatty acids?

Omega 3 fatty acids are naturally occurring substances that are very important for the human body.

Omega 3 fatty acids have a positive effect on some cognitive processes, such as learning or seeing, and at the same time strengthen the immune system. Thus, omega 3 influences both the physical and mental health of each individual.

Omega-3 fatty acids were originally called vitamin F.

For growth and regeneration, you need linoleic acid (LA) and alpha-linolenic acid (ALA). Unfortunately, the human body cannot produce these omega-3 fatty acids.

For this reason, these essential fatty acids must be taken in the diet so that the body can produce eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Linoleic acid and alpha-linolenic acid are found in vegetable and seed oils, such as rapeseed oil and walnut oil. Eicosapentaenoic acid and docosahexaenoic acid are found in oily fish.

How important is omega 3 fish oil?

Although omega 3 fatty acids cannot be produced by the body itself, they are still essential for human life.

Omega 3 is the basis for the production of other fatty acids.

The European Food Safety Authority (EFSA) and the German Nutrition Society (DGE) recommend a daily intake of 250 mg EPA or DHA.

They fulfil a variety of important functions, but cannot be produced by the body itself. Their requirement must therefore be covered by the diet.

How does omega-3 fish oil work?

Since omega-3 fatty acids are elementary components in the building of cell membranes and are the precursor of many other substances in the body, the regular intake of omega-3 fish oil has numerous health-promoting effects.

The following list lists the 6 most important positive influences.

  1. Omega 3 fatty acids have a positive effect on the heart.
  2. Omega-3 for resulting healthier blood lipid levels.
  3. Omega-3 can reduce inflammation.
  4. Supports pregnancy and child development
  5. Omega-3 ensures healthy cognitive abilities
  6. Omega-3 has a positive effect on brain function?

Omega-3 fatty acids can lower the concentrations of triglycerides in the blood and thus reduce the risk factor for coronary heart disease.

Omega-3 fatty acids improve the flow properties of the blood and at the same time their breakdown products have an anti-inflammatory effect. In addition, these fatty acids reduce the body's LDL cholesterol levels, which can contribute to lowering the risk of cardiovascular problems or high blood pressure.

The positive effects of omega-3 fatty acids on the human mechanism have already been scientifically substantiated. (1) (Source: examine.com)

What side effects can omega 3 fish oil have?

In general, omega-3 fatty acids are not known to have any side effects. Although most negative aspects are associated with omega-3 deficiency, an overdose of omega-3 fatty acids can also lead to adverse effects such as high cholesterol, weak immune system, among others.

An overdose means the intake of more than 5g EPA and DHA per day.

According to the German Nutrition Society (DGE), consumption of 1 - 2 g of omega 3 per day is sufficient.

For heart patients, an overdose can be dangerous and possibly lead to sudden cardiac death.

What alternatives are there to omega 3 fish oil?

For humans, DHA and EPA are the two most important omega-3 fatty acids because they are the prerequisites for healthy heart and brain function. Unfortunately, you can only find DHA and EPA in fish products.

In contrast to DHA and EPA, APA can also be found in plant-based foods.

The third omega-3 fatty acid is alpha-linolenic acid (APA), which helps maintain normal blood cholesterol levels.

If you don't consume fish, you can get APA by consuming nuts, seeds, cooking oils, soy and some vegetables. Fortunately, the human body can partially transform APA into DHA and EPA, thereby meeting some of the omega-3 fatty acid requirements.

The intake of fatty acids can also be supported in the form of fish oil capsules, thus creating a balanced omega-3 balance.

Decision: What types of omega 3 fish oil are there and which ones do you need?

When it comes to making a purchase decision, choosing the right fish oil capsules is not always easy. In order to choose the right omega-3 fish oil capsules for your kitchen, you need to know the advantages and disadvantages of the following 3 types of fish oil capsules.

  • Omega-3 Vegan Capsules

  • Omega-3 Fish Oil Capsules

  • Omega-3 Kids

What distinguishes Omega-3 Vegan capsules and what are their advantages and disadvantages?

Omega-3 vegan capsules (V-Omega) contain the same important EPA and DHA that support the vital functions of the body (nervous, immune and cardiovascular systems) as omega-3 fish oil capsules.

When you buy the high-quality vegan omega-3 capsules, you can take the essential omega-3 fatty acids into your body without fish oil.

Advantages
  • High quality algae oil
  • EPA + DHA high doses
  • 100 % vegan &
  • sustainable
Disadvantages
  • Capsule made from pork gelatine
  • About expensive

DHA and EPA fatty acids of omega-3 are found in microalgae from the sea, which the fish also ingest. Therefore, "V-OMEGA" consumers support the preservation of the world's fish stocks and thus contribute to sustainability.

Omega-3 from algae oil is the solution for both animal welfare and environmental protection.

What distinguishes omega-3 fish oil capsules and what are their advantages and disadvantages?

The best source of omega-3 fatty acids is fatty fish, as EPA and DHA are already contained there. Fish oil capsules are the best solution for vegans and people who do not consume fish.

Fish oil capsules are produced from the liver of fish, so they already contain vitamin A and D and algae extract with natural carotenoids. Furthermore, fish oil capsules are more effective for pregnant women than algae oil capsules.

Advantages
  • Best source of Omega 3
  • Higher efficacy during pregnancy
  • More energy and water efficient production
  • More cost effective
Disadvantages
  • Additional pressure on wildlife

In contrast to the algae capsule, the production of fish oil capsules consumes less energy and water.

What distinguishes Omega-3 Kids and what are its advantages and disadvantages?

The toxin-free omega-3 fish oil capsules for kids have an irreplaceable positive effect on children's development.

The Omega-3 Kids capsules are smaller so that children do not have problems swallowing them. Furthermore, the capsules can be cut open and mixed into food to prevent children from having further swallowing problems.

Advantages
  • No swallowing problems
  • Against ADHD
  • Against skin diseases
  • Against depression
Disadvantages
  • Not suitable for young vegans

The positive influences of Omega-3 Kids can help children with ADHD, skin diseases (e.g. children's rheumatism, skin allergies) or depression and thus contribute to a balanced lifestyle.

Buying criteria: Use these factors to compare and evaluate omega 3 fish oil

In the following, we will show you the different aspects you should look for when you want to buy omega 3 fish oil.

In summary, the following criteria are:

Dosage

Omega-3 fatty acids are stored in people's fatty tissues, so it is possible to survive healthily for a long period without a regular supply.

According to the German Nutrition Society (DGE), you should take 250 mg of EPA and DHA daily to protect yourself from various diseases.

High-quality fish oil with an omega-3 content of at least 2 g per daily dose is prescribed by most doctors for heart rhythm disorders, rheumatism or depression. To be able to cover this basic requirement, the family doctor recommends two fish portions per week.

If you want to learn more about the dosage, you can watch the video below.

Quality

Quality has its price. For this reason, value for money is the most decisive factor when buying omega 3 fish oil. According to experts, a product with high dosage is more valuable than a cheap product with less efficiency.

Secondly, the valid question can arise whether the supplement contains only pure fish oil with omega-3 fatty acids without unnecessary additives or fillers, or whether the ingredients can possibly lead to a reduction in the quality of the product.

Did you know that the cheaper fish oil capsules are not made from the oil of high-quality deep-sea fish?

Cheaper fish oil products are usually produced from fish waste that is not otherwise available for sale. These omega 3 fish oil capsules can be both more hazardous to health and less effective.

Another quality criterion is the Totox value, which shows the degree of oxidation of the unsaturated fatty acids in the fish oil. A low Totox value is a prerequisite for high-quality omega-3 fish oil capsules. Make sure that the manufacturer indicates this value on the package.

Omega 3 capsules also have a soft capsule made of gelatine. Unfortunately, the origin of the gelatine is sometimes difficult to find because it is not indicated by the manufacturer. Make sure that you always know the origin of the gelatine in the food supplement.

Trivia: Interesting facts about omega 3 fish oil

What food is omega 3 fish oil found in?

Quality food is the secret to healthy living. Every meal should contain EPA and DHA rich food.

The following foods are rich in EPA and DHA:

  • Fish oil, fish (mackerel, sardines, anchovies, herring, salmon): the main source of healthy omega-3 fatty acids. For optimal body nutrition, it is recommended to consume oily fish twice a week.
  • Seeds (linseeds, sesame seeds, pumpkin seeds, hemp seeds)
  • Avocados
  • Nuts (walnuts, almonds, pecan nuts, macadamia nuts)
  • cold-pressed olive oil
  • Products from pasture-raised animals
  • Coconut butter: perfect vegetable source of saturated fats.

What is the shelf life of omega 3 fish oil?

This valid question often comes up after buying an omega 3 product. Of course, the shelf life depends on a number of factors, including when the product was sealed or opened.

The cool storage of fish oil can significantly reduce oxidation. In the case of annual packs, the problem arises that the storage period and constant opening lead to quality deterioration. In principle, fish oil capsules can be kept for up to 2 years. Fish products should be stored in the refrigerator after opening.

Algae oil usually has a shelf life of up to 2 years. Linseed oils have a shelf life of only 5 months.

What happens if too little omega 3 fish oil is taken?

The lack of nutrients has negative consequences for human health. People who do not like to eat fish, despite their own eating habits and particular lifestyle, need to take enough fatty acids every day to prevent themselves from omega-3 deficiency.

A deficiency of omega-3 fatty acids causes a lack of important long-chain fatty acids. A low level of omega-3 fatty acids has clearly recognisable physical symptoms.

Most symptoms of omega 3 deficiency are:

  • Cardiovascular diseases
  • weakened immune system
  • Impaired vision
  • Skin problems
  • Muscle weakness

How does omega 3 fish oil work for depression?

The number of people suffering from depression is rising steadily every year. In Germany, every tenth inhabitant suffers from depression once a year.

Scientists have already pointed out the clear connection between depression and omega 3 fish oil consumption in numerous studies.

Consuming fish or omega-3 can reduce or even eliminate depression and anxiety. The positive effect of the antidepressant citalopram can normalise the individual's depression levels after a few weeks.(2)

The positive relationship between omega-3 fatty acids and their influences on depression has been scientifically established.

How does omega 3 fish oil work against dementia?

Neuroscientists have been discussing the link between the effects of omega 3 fish oil and dementia for some time. It has been scientifically proven that high levels of EPA and DHA can reduce the risk of dementia.(3)

Reduced brain volume plays a role in the development of Alzheimer's disease. American research found that higher levels of EPA and DHA correlate with greater brain volume.(4)

Why does omega 3 fish oil have a positive effect on the skin?

Omega fatty acids are essential building blocks for building the surface layers of the skin. Regularly consuming foods that contain omega 3 can improve the quality of the skin.

The effects of omega 3 on the skin have already been studied in the research field. The results of the scientific study showed that omega-3 fatty acids can also alleviate many skin problems when applied topically.(5)

Applying the fish oil to the skin makes the skin resistant and hydrated.(5)
