Experts in Germany agree that omega-3 fatty acids, which we take in through food, are essential for our brain performance, vision and heart function. In addition, they strengthen the immune system and inhibit inflammation in the body. However, we take in the majority of these valuable fatty acids through the consumption of fish.

So what if we prefer a vegan or vegetarian lifestyle or for other reasons do not want to eat fish or only a little? In this case, algae oil is an excellent substitute. In the following article, we explain what needs to be considered.


  • Algae oil is the vegan counterpart to fish oil, containing valuable omega-3 fatty acids. It is available as capsules, tablets or drops.
  • Even a small dose is enough to cover your needs. The important omega-3 fatty acids include the essential parts of DHA, EPA and DPA, which cause a well-functioning brain, eyesight and heart function.
  • There is a wide range of algae oils on the market, so it makes sense to take a close look at the preparations to make the best decision on what to buy. There are also some aspects to consider when using and dosing the algae oil.

The best Algae Oil: Our Picks

To make sure you don't lose your bearings in the huge range of products, in the following section we give you some concrete examples of algae oils with which you are guaranteed not to go wrong. You are sure to find the right one for you.

Buying and evaluation criteria for algae oils

To help you find the right algae oil, we have summarised the most important criteria that you should consider when buying algae oil so that you can find the right algae oil for you:

In the following section, we explain what exactly you need to consider so that you can make the right decision for you.


Not all algae oils have the same dosage. The DHA content, which is important for brain function and vision, as well as the EPA and DPA content, which are both responsible for strengthening heart function, are dosed differently in the oils.

Here you should note how high the algae oils are dosed in each case and compare it with the recommended daily dose for you. The higher the dosage, the less of the oil you need to take.

How much of the oil you need depends on your individual omega-3 index, which you can calculate free of charge. If the dosage is too high or too low, you will not achieve the desired effect.


Algae oils are available in different quantities and forms. In drop form, the quantity ranges from 10 ml to 250 ml vials. Most require an average of 1-5 drops, which means you can choose how long you want to have some of the oil.

But be careful: more oil does not necessarily mean more quality. Rather, a smaller quantity also promises a higher dosage and quality. As capsules and tablets, the number varies between 60 and 200 capsules per tin.

Again, you should pay attention to the dosage. And of course it depends on whether you are already sure and want to buy a stock or whether you would rather try it out with a smaller quantity first.


It is worth taking a look at the additives in algae oil. Often the oil does not consist of pure algae oil but of another carrier oil and is only enriched with algae oil. In addition, vitamins such as vitamin E and vitamin D3 are often added. This offers advantages such as a longer shelf life.

On the other hand, the oil is also stretched and more of it has to be consumed. Furthermore, if many different additives are contained in the product, it is all the more difficult to trace and check under which conditions the production has taken place.


Unlike fish oil, algae oil itself is quite tasteless. However, there are algae oil models that have a fruity taste or aroma, e.g. due to added vitamins. This makes consumption all the more pleasant, of course. However, this is a matter of taste in the truest sense.

Guide: Frequently asked questions about algae oils answered in detail

In the following section we clarify frequently asked questions so that you are well informed when you want to try algae oil.

Who is algae oil suitable for?

Basically, you can assume that every person who eats a balanced diet and whose diet contains enough omega-3 fatty acids, such as those found in fish or also in psyllium, is sufficiently supplied.

I.e. if you do not eat fish often or not at all, then algae oil is definitely interesting for you, as the fatty acids it contains are essential for your brain, vision and heart function.

Although you can also find these important fatty acids in other vegetable oils such as rapeseed, linseed or walnut oil, they are not already so suitably prepared and dosed as food supplements.

In addition, algae oil, which is extracted from the dulse, for example, is especially recommended during pregnancy or for diseases such as rheumatism or arthritis.

What types of algae oils are there?

There are many types of algae oils. The algae oil itself is of course always the same, but the way it is prepared varies depending on the model.

They differ in the dosage, in the taste, which is created, for example, by the use of citric acid, in the quantity and in the additives. We have described in detail what you can look out for in particular in the section above.

What are the side effects of algae oil?

There are no side effects to worry about at first. However, in case of an overdose, there is a risk of interaction, e.g. with anticoagulant drugs such as aspirin.

Too high a dose can have an effect on the flow properties of the blood and thus increase the risk of bleeding for a short period of time.

In addition, an overdose can also increase LDL cholesterol levels and, in diabetics, weaken the immune system. As you can see, you should always stick to the recommended amount or the amount that suits you and not exceed it.

Can algae oil be used for cooking?

Since algae oil is not heat-resistant, you should not use it for frying or similar purposes. However, it is very popular in salads or smoothies, which you can easily make at home in a smoothie maker. To enjoy the smoothie cold, it is definitely worth adding an ice crusher.


Under certain circumstances, e.g. a diet low in fish, the body lacks the significant omega-3 fatty acids, which play a crucial role in vision, brain performance and heart health, among other things.

To compensate for this deficit, researchers have developed algae oil as an alternative to fish oil. To find the right oil, you need to pay attention to your individual omega-3 index and pay close attention to the ingredients and their quality.
