  • High quality primrose seed oil providing gamma-linoleic acid
  • Easy way to increase the supply of GLA
  • May slow down the creation of wrinkles
  • Positively influences skin nourishment
  • Supports fatty tissue reduction
  • Prevents the development of cancer
  • Supports the processes of treatment of atopic dermatitis
  • Reduces the symptoms of PMS

Jarrow Evening Primrose is a high-quality oil from primrose seeds. It demonstrates many pro-health properties, which is related to the content of essential unsaturated fatty acids. It is distinguished by the high content of gamma-linoleic acid with the large spectrum of effects in the organism.

Primrose oil provides gamma-linoleic acid, abbreviated GLA. It is a fatty acid classified to essential fatty acids (EFAs), which needs to be provided with food, as the organism does not have the ability to produce it. It is a precursor of eicosanoids, including PGE1, a prostaglandin demonstrating hormonal functions, thanks to which it influences the functioning of the organism.  Gamma-linoleic acid also has influence on the synthesis of prostacyclins and thrombaxanes. All these substances regulate local metabolism of tissues and their efficient synthesis is essential to maintain proper functions of the system.

Improvement of skin quality
Proper supply of gamma-linoleic acid is visible mainly in the state of skin. Its deficits cause dryness and inhibit wound healing. Supplementation with gamma0linoleic acid is indicated as the form of reduction of the pace of aging, as it slows down the creation of wrinkles. Its activity in this area is related both to the stimulation of the production of the above mentioned prostaglandins and direct participation of this acid in the creation of mucous membrane.

Anticancer effect
Gamma-linoleic acid is also indicated as the form of prophylaxis or even complementation of cancer therapies. It has cytotoxic effect on cancer cells, preventing their development in the organism. It not only reduces the pace of gene expression of these cells, but is also limits their access to nutritious substances. Primrose oil may also support cancer therapy working synergistically with some drugs administered during chemotherapy.

Support in fatty tissue reduction
Gamma-linoleic acid may be also used in order to increase the pace of weight loss. Its supplementation intensifies the process of beta-oxidation, i.e. oxidation of fatty acids in order to derive energy. GLA also exhibits the activity towards brown fatty tissue. It was proven that administration of primrose oil has stimulating effect on metabolism, supporting weight loss.

Support of atopic dermatitis therapy
Due to the problems with the conversion of linoleic acid to gamma-linoleic acid in people suffering from atopic dermatitis, it seems logical to supplement GLA in order to reduce the symptoms of the disease. It was confirmed by the results of studies, in which the administration of gamma-linoleic acid alleviated the course of atopic dermatitis. This acid also has prophylactic effect; when administered to children in the risk group of atopic dermatitis, it reduces the symptoms of the diseases in case of its occurrence in the future.

Treatment of diabetic neuropathy
Disorders of Δ-6-desaturation, i.e. transformation of linoleic acid to gamma-linoleic acid, are also noted in people dealing with diabetes. Although supplementation, both with linoleic and gamma-linoleic acid does not have a confirmed therapeutic or prophylactic effect on diabetes, it may be used as treatment supplementation in diabetic neuropathy. Supplementation with primrose oil demonstrates antifibrotic and anti-inflammatory effect, which helps in the fight with this disease. 

Reduction of PMS symptoms
Supplementation with primrose oil may also be used as an element of therapy of premenstrual syndrome. It was proven that supplementation with gamma-linoleic acid is conducive to reduction of characteristic symptoms of PMS.

Summing up, Jarrow Evening Primrose is a high-quality, natural source of gamma-linoleic acid. It allows to easily increase the supply of this compound, incredibly vital for the functioning of the organism. Thanks to a wide spectrum of effects, it may be used both in the therapy of some disorders and in the prophylaxis of cancers as well as to slow down the pace of aging.

Calories are the conventional name of the unit expressing the energy value of food, the demand and energy expenditure in human body, which in fact is 1 kilocalorie (1 kcal). 1 kilocalorie is the amount of thermal energy required to heat 1 g of water and 1 degree Celsius. The SI unit of thermal energy is 1 joule (1J), equal to approximately 4,185 kcal.
The energy value is determined by the chemical composition of the food product, by means of the so-called. physiological equivalents. Most often Atwater equivalent is used: ratio for protein 4 kcal / g, for carbohydrates 4kcal / g, and for fat - 9kcal / g.
The energy value carried out with the so-called. "Caloric bomb" is equivalent to the physical energy, amounting to 4.1 kcal per 1 g carbohydrate to 5.65 kcal per 1 g protein, 9.45 kcal per 1 g of fat.
Nutritional value, determines the suitability of a food product for realizing life functions of human, the higher it is - the higher bioavailability and lower quantity for consumption for obtaining the effects.




Fat is an essential nutrient plant and animal organisms. Because of the nutritional value and composition of fats are divided into: saturated (mono-saturated and multi-saturated fatty acids) and unsaturated fatty acids (including essential fatty acids - EFA). The group of lipids include lipids (triacylglycerols, waxes), complex fats (glycolipids, phospholipids), sterols and isoprenoids. Saturated fatty acids is a group of fatty acids having different carbon chain lengths, in which except for the carboxyl group, each of the carbon atoms is bound by a single bond. May adversely affect the lipid profile, so they can be used in limited quantities. Fats are a concentrated source of energy, with different flavours, facilitating the consumption and swallowing of food. They have building functions (part of cell membranes and co-create the white matter of the brain). EFAs are precursors of tissue hormones and biologically active compounds. The unsaturated fatty acids include fatty acids from the group Omega-3, Omega-6 and Omega-9 (the last digit indicates, on which, counting of the end of the chain, there is a double bond in the appropriate carbon chain. The essential fatty acids include: acids, medium-Omega-3 [n-3 ] included in EFAs [essential fatty acids], and long chain (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) Omega-6 and Omega-9. the number indicates that the last double bond in the carbon chain is on the third from the end carbon atom. The acids from the omega 3 group are essential components of cell membranes, they are precursors of eicosanoids and biological activators. They must be combined with ingestion in suitable proportions of Omega-6 acids.
Dosage: Depending on demand and applied diet. It is generally accepted that fats should constitute 20-30% of the energy (calorie) of meals daily.


Evening primrose oil


Evening primrose oil – a source of essential unsaturated fatty acids, mainly omega-6. Linoleic acid, associated with healthy carbohydrate metabolism, is the predominant one. It is indicated that impaired conversion of linoleic acid occurs in diabetics and its increased intake may reduce symptoms of diabetes.

Furthermore, evening primrose oil is valued for its beneficial impact on the cardiovascular system. It inhibits blood platelet aggregation and has the ability to optimise the lipid profile. Owing to that, it is an effective way to prevent cardiovascular diseases, including atherosclerosis, in multiple ways.

Evening primrose oil is often recommended to individuals who want to improve the condition of their joints. It stimulates the regeneration of joint cartilage and may reduce symptoms of rheumatism. Furthermore, it is said that it promotes fertility both in women (due to its beneficial impact on endometrium) and men (by improving semen quality).

When taking dietary evening primrose supplements, we should pay attention to their storage. As a source of EFAs, this oil is sensitive to sunlight and heat. Because of that, it should be kept in a dark, cold place.

Gamma-linolenic acid


Gamma-linolenic acid (GLA - unsaturated fatty acid from the Omega 6 group, present in plant foods and is synthesized within the human body from linoleic acid. Participates in the synthesis of eicosanoids. Increases immunity. GLA deficiency impairs the skin, hair and nails condition. It is an additional component of supplements containing essential fatty acids (EFAs) complemented with vitamin E, which has antioxidant properties, available at
Dosage: the proportions of the ratio between Omega 3 and Omega 6 in the ratio of 1: 1 to 1: 5 enables flexible dosing.
