Elements of Evening Primrose Oil

Evening primrose is rich in amino acids and essential fatty acids such as omega 6. These are transformed into hormone-like substances called prostaglandins, which condense allergic response and inflammation.

The major components in evening primrose include: alanine (0.5%), arginine (1.5%), aspartic acid (1.2%), beta-sitosterol (1.2-2.5%), calcium (1.3-1.8%), cellulose (27%), gamma-linolenic acid (0.5-10%), glutamic acid (2.7%), glycine (1%), fat (15-32%), fiber (43%), histidine (0.4%), isoleucine (0.5%), leucine (1%), lignin (16%), linoleic acid (12-22%), lysine (0.3%), methionine (0.6%), phenylalanine (0.7%), proline (0.6%), protein (15-17%), serine (0.9%) threonine (0.4%), tryptophan (up to 1.6%), tyrosine (0.4%), valine (up to 0.8%) and other lesser constituents.


How EFA’s Supports the Body

Essential fatty acids support the body in many ways:

  • EFA’s are vital to the electrical reactions of cells. These electrical signals maintain regular heartbeats and regulate chromosome stability.
  • EFA’s carry vitamins, enhance metabolism and transport oxygen to the tissues.
  • Provide indispensable to the adrenal glands, brain cells, retinas, sensory organs, synapses and testes.
  • Act as solvents to eliminate hardened fat inside the human body.

Gamma Linolenic Acid

Evening Primrose Oil has a high concentration of Gamma Linolenic Acid. GLA is a polyunsaturated fatty acid that aids the body to manufacture energy, and helps to form parts of the structural fats that encompass bone marrow, the brain, cell membranes and muscles.

Gamma linolenic acid is transformed by the body into prostaglandins. Prostaglandins are hormone-like substances with anti-inflammatory properties, produced in the body's tissues acting like a blood thinner and blood vessel dilator. Deficiency in Prostaglandin can disrupt the nerve impulse transmissions, increase blood clotting time, inflammation and weaken immune response.

Evening primrose oil with a high concentration of gamma linolenic acid is beneficial in ailments related to essential fatty acid deficiency and the inability to metabolize essential fatty acids.



Studies on evening primrose have been promising; at this time insufficient conclusive data is available.


Side Effects

People with seizure disorders should only use omega-6 supplements of any kind, under the care and supervision of a licensed medical doctor. Omega-6 including gamma linolenic acid has had reports of inducing seizures in seizure-vulnerable persons.



Check the percentages of gamma linolenic acid [7-10%] and linoleic acid [40-75%].

The best evening primrose contains 10.3% gamma linolenic acid and 75% linoleic acid, available as carrier oil.
