Linseed oil is a lubricant produced by crushing the fruits of the same name, which ooze this substance from the inside. It is certified as one of the best culinary ingredients because it combines two excellent qualities that every cook desires: good taste and good health. It is therefore in great demand.

We want to give you all the information you require about the product you wish to purchase, so that you are properly informed about it before you choose to buy it. This way you will avoid unpleasant surprises once you have it in your hands, as you will have made the right choice from all those available.


  • Linseed oil is a lubricating liquid made by crushing flax seeds, which in turn come from a wild vegetable. It is completely natural and has a lot of Omega-3, an important nutrient for the body.
  • This oil has many benefits, however it deteriorates quickly. Because of this many companies that manufacture it decide to add chemicals to it to preserve it. This can be done either with artificial preservatives or by mixing the "base" element with other similar juices.
  • All things considered, linseed oil is scarce and rare. Therefore, the right odour, acceptable purity and good packaging are guarantors of quality and durability. This will help to know how it will be used, as even those intended for cooking can be used in different ways.

The Best Linseed Oil: Our Picks

The number of suppliers of these consumables is quite low. This results in a disadvantage - little competition - but also in the advantage that you can get it quickly. In order to find the best ones, we list the examples that are rated as excellent.

Buying guide

At first glance, anyone would assume that the choice of this type of material is easy, given that it is a lubricant known throughout the world. However, there are many values that go into its quality and functionality, so it is important to get to know it before making this assumption.

What is linseed oil and what are its benefits?

It is a liquid that emanates from linseed, the seed that gives it its name and which comes from the wild plant linum usitassimum, when crushed. Due to its characteristics, it is a juice that is extracted in small quantities, and it is rare to find in abundant presentations, and if so, it tends to be highly valued.

One of the reasons why this concoction is so highly regarded is that, in addition to being quite healthy, it is rich in Omega-3, a fatty acid that is also present in, for example, fish and chicken, and whose consumption is recommended for the development of cognitive skills.

All this makes it very popular with vegans and vegetarians. On the other hand, unlike other vegetable oils, such as coconut oil, this product is not fattening. This is due to the fact that it does not contain saturated fats and a very small amount is required for its use, which is usually quite limited.

All these characteristics make it highly advisable to use this material, which also has a good taste and is suitable both for enlivening meals and for preparing them from its basic composition. It is therefore very versatile.

  • Contributes to a balanced diet
  • Flavours food
  • Not fattening
  • Affordable
  • Difficult to find
  • Comes in small quantities
  • Must be oversupplied
  • Expires quickly

Flaxseed oil with preservatives, without preservatives and cosmetic - what should you pay attention to?

It should be remembered that this is an oil and, as such, has the uses that such consumables generally have. From olive oil to coconut oil, they all have more or less the same performance.

Linseed comes from the crushing of the seeds of the same name. This makes it relatively scarce, so there is little diversity of products made from it.

Flaxseed oil with preservatives. Flaxseed oil in its natural state does not last long, but expires quickly. Many companies that extract linseed oil choose to add additives to prolong its life. These are usually easy to detect because they have an impact on the smell and colour of the oil.

The colour should range from a slightly dark amber to a light yellow. These latter shades can indicate two things: either the addition of extra elements and chemicals, or a higher percentage of other oils used to make the base oil.

Flaxseed oil without preservatives. This type has the great disadvantage of being very short-lived, so it must be used quickly. It varies in colour from light brown to dark amber. It is one of the most difficult forms of this product to find.

As it deteriorates too quickly, it is not economically profitable to market it in this form. For this reason, it is not readily available, but if the customer prefers this variant, it should be used quickly.

Cosmetic linseed oil. This is the least used variety. It is a type used only for dermal moisturising, healing and other purposes. Its uses are the same as those of any other oil in this field.

With preservatives Without preservatives Cosmetic
Duration Long Short Long
Colour Yellow Amber Yellow
Thickness Low High Low
Profile Bitter Strong Mild

Buying criteria: factors that allow you to compare and rate different models of linseed oil

While it is true that some of the points that improve or deteriorate the quality of this type of liquid are obvious and fully deductible, there is another variety that is not. Precisely because it is so specific, and so relatively new on the market, there are some things that need to be observed very carefully.

The quality of the juice is not always decisive in determining its effectiveness. As is well known, quality in itself can be disadvantageous because if it is not correctly administered, it can make the already small quantity that the containers usually contain last less time. Some details to consider in this regard are:

  • Packaging
  • Purity
  • Odour
  • Uses


The bottle is fundamental because, depending on its shape, it is possible to save more or less of the contents. Some larger, more detailed bottles have delivery forms, such as droppers or cup-shaped openings. This is a way of helping the user to ration.

Remembering that it comes in fairly small quantities, this becomes very important, because most bottlings range from 60 to 100 millilitres, with rare exceptions that go up to 200 and more. Droppers are the only effective dosage form and are recurrent in cosmetics, which value performance more.

Purity refers to how much of the brew is authentically linseed, remembering that additives are often present. This is determined by the colour of the material, which should be darker. But many companies that make this juice have this information on the back of the juice.


The fragrance of this liquid should be similar to that of nuts, because it comes from the seeds of a vegetable. Although this is one of the most difficult points to determine, it is worth checking to see how effective the product is. It is to be expected that cosmetics have chemical odours.

However, this is different for those that are used in a culinary form. In this case, preservatives try to preserve the aroma, as these components are generally odourless. The presence of similarities with essences of other condiments, such as canned foods, may indicate the existence of additives


Even those for cooking purposes can be used cosmetically, as can most lubricants of this type. These do not have some of the elements that enhance the quality of those used on the skin, such as pro-vitamins, but are still moisturising and regenerating.
