What is linoleic acid?

Linoleic acid is a natural acid and is found in fatty oils. It belongs to the group of essential fatty acids and is a doubly unsaturated fatty acid. The oily linoleic acid in its pure form is colourless and almost odourless. Linoleic acid belongs to the group of omega-6 fatty acids. The most important omega-6 fatty acids in the human body are:

  • Linoleic acid
  • Gamma-linolenic acid
  • Arachidonic acid

The special feature of linoleic acid compared to the other acids is that our body can form the other acids itself with the help of linoleic acid.

Where is linoleic acid found?

You can find linoleic acid in both animal and plant products. Fatty meat, milk and dairy products are the main sources of linoleic acid. The highest natural occurrence of this versatile and very important acid is found in grape seed oil and safflower oil. But various other oils also have a high linoleic acid content. Most of the well-known and common oils such as soybean oil, sunflower oil or linseed oil should be mentioned here.

What is the linoleic acid content of the various oils and foods?

The linoleic acid content of different foods varies. The acid content tends to be highest in oils. However, various foods also have an above-average acid content. The following table gives you a quick overview of the respective linoleic acid content:
Food Linoleic acid content per 100g
Linseed oil 52800 mg
Soybean oil 7700 mg
Rapeseed oil 8584 mg
Olive oil 855 mg
Walnut oil 12200 mg
Walnuts 10172 mg
Chia seeds 19000 mg
Avocados 111 mg
Lard 1005 mg

What is the function of linoleic acid in our body?

The essential fatty acid takes over and supports many functions in our body. Linoleic acid has the following functions in our body:

  • Regeneration and cell renewal of the skin
  • Strengthening of the hair
  • Blood pressure lowering effect
  • Support of muscle development

Since the omega-6 fatty acid is an important component of the human skin, our body needs it for the regeneration and cell renewal of our skin. A good linoleic acid balance in our body can help our skin to have a radiantly fresh and youthful appearance. Here we can support both "from the inside" in the form of nutrition, and "from the outside" with the help of cosmetics.

Our body absorbs the important components through the skin and incorporates the required active ingredients into the cells. Linoleic acid not only gives our skin a healthy appearance. The hair is also strengthened and invigorated by this fatty acid. Linoleic acid promotes the growth of beautiful and shiny hair. In addition to supporting the development of radiant skin and hair, linoleic acid has several other useful functions in our body. The omega-6 fatty acid is very well known for its blood pressure lowering effect.

A good blood pressure is immensely important for the metabolism and thus for maintaining our health. Especially for the athletes among us, linoleic acid is an important part of the diet, as it ensures shorter regeneration phases in our muscles. Due to this effect, you can support your training programme with targeted nutrition in order to achieve faster results.

When is there an increased need for omega-6 fatty acids?

In some life situations there is an increased need for omega-6 fatty acids. Especially children who are growing need the essential fatty acids to give the body the necessary energy and the basic building materials for cell formation and muscle growth. For exactly the same reason, the requirement is increased during pregnancy. Furthermore, various diseases can have an influence on the current requirement.

What consequences can a deficiency of the important omega-6 fatty acids have?

The body can produce the most important omega-6 fatty acids itself from linoleic acid. Linoleic acid thus forms the basis for a good basic supply of the vital omega-6 fatty acids. The consequences for our body are very wide-ranging in the event of a deficiency or undersupply of the essential acids.

The first visually visible signs of a deficiency can be seen in the appearance of the skin and hair. The skin becomes flaky and dry and eczema can occur more frequently. The hair becomes dull and lacklustre, and may even fall out. The consequences, however, extend to the inside of the body.

From increased blood pressure and disturbed heart rhythm to kidney and liver damage, a poor supply of omega-6 fatty acids can have far-reaching, serious consequences.

What is the difference between linolenic acid and linoleic acid?

Be careful not to confuse the two: Linolenic acid and linoleic acid are different. What both acids have in common is that they are essential fatty acids and have similar functions in our body. Furthermore, they use the same enzyme system for further utilisation or conversion in our body.

The difference between the two acids lies in their composition. While linoleic acid is an omega-6 fatty acid, linolenic acid is a triple unsaturated fatty acid.

The omega-3 and omega-6 fatty acids in our body should ideally be in balance. In order to be able to achieve a balance here, it is important to know that linolenic acid, just like linoleic acid, occurs primarily. However, the proportion of linoleic acid is usually significantly lower than the proportion of omega-6 fatty acid. This fact must be taken into account when consuming.

Decision: What types of linoleic acid are there and which one is right for you?

Basically, you can distinguish between three different types of fatty acids:

  • Saturated fatty acids
  • Monounsaturated fatty acids
  • Polyunsaturated fatty acids

What are saturated fatty acids and what are the advantages and disadvantages of saturated fatty acids?

The term saturated fatty acid is derived from the chemical nature of the acid. Here, the carbon atoms do not have a double bond. Saturated fatty acids are mostly found in solid fats. Well-known saturated fats are, for example, butter, coconut oil and beef fat. Saturated fats are particularly suitable for processing food under heat, as is required for deep-frying and frying.

Advantages
  • Lower blood lipid levels
  • Keep triglyceride levels low
  • Lower HDL cholesterol levels (lauric and myristic acid)
Disadvantages
  • Raise LDL cholesterol levels (palmitic acid)
  • Usually found in solid form
  • Usually found in processed foods

What are monounsaturated fatty acids and what are the advantages and disadvantages of unsaturated fatty acids?

Monounsaturated fatty acids have a double formation in the chemical formula. This is the reason for the name of this fat group. Monounsaturated fatty acids are not essential, which means that our body can produce them itself and is not dependent on external supply. Rapeseed oil, jojoba oil and fish oils, to name but a few, belong to the monounsaturated oils.

Advantages
  • Lowering LDL cholesterol levels
  • Improving insulin sensitivity
  • Body can make them itself
Disadvantages
  • Oils are high in calories

What are polyunsaturated fatty acids and what are their advantages and disadvantages?

The naming of polyunsaturated fatty acids lies in the chemical nature and has a multiple double bond in the carbon atoms in the formula. The polyunsaturated fatty acids are further divided into the essential fatty acid groups omega-3, omega-6 and omega-9 fatty acids.

The name is based on the position of the double bond of the carbon. As an example: The double bond in an omega-3 fatty acid is located on the 3rd carbon atom.

Advantages
  • Promote growth and regeneration
  • Improve skin appearance
  • Improve cholesterol levels
Disadvantages
  • Cannot be formed by the body itself
  • High calorie content
  • Difficult to achieve a balanced ratio of omega-3 and omega-6 fatty acids

Buying criteria: You can compare and evaluate linoleic acid based on these factors

In the following, we would like to show you which factors you can use to compare and evaluate linoleic acid. This will make it easier for you to decide whether a particular linoleic acid is suitable for you or not. In summary, these are:

  • Cold-pressed oils
  • Refined oils

Buying criterion for cold-pressed oils

In cold-pressed oils, only the best and unblemished fruits are used for processing. This results in a very high quality and full-bodied taste. With this processing method of cold pressing - up to 27 degrees Celsius - the yield of the fruit is lower than with processing under heat.

The decisive advantage of this type of processing lies in the quality of the oils. The vitamins and active ingredients of the fruit are preserved as far as possible and thus increase the nutritional value of the oil.

Purchase criterion for refined oils

This industrial processing method guarantees a consistent taste. Large quantities of the oil can be produced. The quality of this processing has continued to improve in recent years. Furthermore, there is a large selection to choose from. The most important thing to know about linoleic acid is that it cannot be produced by the body itself.

For this reason, linoleic acid is absorbed through our food. As already mentioned, the important fatty acid occurs in different forms and in different foods. Thus, a balanced diet and the use of different and high-quality oils can ensure a sufficient supply of linoleic acid. Furthermore, the acid occurs in very many foods. This makes the intake of linoleic acid very easy in most cases.

Our body can store linoleic acid well. Another point to consider is the ratio between omega-3 and omega-6 fatty acids. Since our body uses the same enzyme to break down the two groups of fatty acids, a ratio of between 5:1 of omega-6 fatty acids is recommended. If too much linoleic acid is consumed, it can have a pro-inflammatory and vasoconstrictive effect due to the conversion process in the body to arachidonic acid. This should be avoided if possible.

A good diet with healthy, varied food helps to consume the ideal amount of linoleic acid. To prevent a deficiency, especially in the case of an increased need for omega-6 fatty acids, or to support it in the case of an undersupply, the intake of evening primrose oil is recommended.

Facts worth knowing about linoleic acid

As already mentioned, linoleic acid is a real all-round miracle of nature in many areas. Not only does it support the functions of our body in the area of nutrition, but also in the cosmetic area, the fatty acid finds versatile areas of application due to its properties.

What is the function of linoleic acid in cosmetics?

The very versatile linoleic acid is also used in many different cosmetics. The positive properties of the fatty acids are mainly used in various creams. First and foremost, the moisturising effect is used. Especially in the field of anti-ageing products, we can hardly do without linoleic acid.

Linoleic acid in cosmetic products reduces the water loss of the skin through its properties. Thus, the skin is sustainably protected from drying out. The skin gets a fresh and even complexion and the skin feels soft and smooth. Creams with a high linoleic acid content are usually perceived as very light and are absorbed comparatively quickly into the skin.

It penetrates the skin's uppermost protective layer and provides the cells there with the skin's necessary natural moisture. As a result, the cream does not appear greasy, but is perceived as very light.

Function in skin irritations, light damage or age spots

Linoleic acid has an anti-inflammatory effect. This positive property is particularly noticeable in acne. The component of linoleic acid in the special cream for acne can provide good support for the healing process of the stressed skin.

From the point of view of optical beautification, the effect of improving age spots and hyperpigmentation of the skin falls into this category. Thus, creams containing linoleic substances promote the regulation of melanin synthesis. This synthesis is responsible for dark discolourations of the skin. The same effect is seen with age spots.

When should cosmetics containing linoleic acid be used?

Especially in the seasons with strongly fluctuating weather conditions, our skin and hair are exposed to strong stress. The temperature and humidity fluctuations between the dry, heated rooms and the wet, damp and cold outdoors demand a lot from our bodies.

To give our skin and hair an optimal basis for a radiant and healthy appearance, especially during this time, we primarily use cosmetics containing linoleic acid.

The essential fatty acid prevents the skin from drying out and also provides our skin and hair with additional moisture. For skin irritations, minor inflammations, burns and sunburns, creams containing linoleic acid support the regeneration of the skin.

What should I look for when buying linoleic acid?

As in many areas, the higher and better the quality of the oils and fats, the more effective and better the effect in our body. Essential fatty acids are best and of the highest quality when they are present in their most natural form possible, with as few processing steps and additives as possible. This applies to both food and cosmetics. In the food sector, the highest quality oils and fats are those that are as natural as possible.

Cold-pressed oils have the highest content of vitamins and high-quality fatty acids. In refined oils, many important components are lost during processing. This means a loss of quality and the content of important building blocks for our body decreases significantly. In the field of cosmetics, it is important to ensure that as few mineral oils as possible are used in cosmetics containing linol.

Mineral oils have other properties than linoleic acid. This can go so far that the properties have an opposite effect on each other and thus an initially light, quickly absorbed cream becomes a greasy, heavy cream. Especially in the field of beauty cosmetics, you should make sure that the cream you are looking for meets your requirements and personal needs. Depending on the skin type, the requirements are different.

In addition, the skin's need for moisture can vary greatly. In order to ideally meet your personal needs, many manufacturers and specialist consultancies offer product tests.
