Evening primrose oil is a cold pressed seed oil fromOenothera biennis a flowering plant native to North America. It is one of the richest plant sources of gamma linolenic acid (GLA), an omega-6 fatty acid that the body uses to produce prostaglandin E1 (PGE1) a vasodilatory, anti-inflammatory eicosanoid involved in hormonal regulation, skin barrier function, and immune signalling.

GLA (gamma-linolenic acid) is an omega-6 fatty acid produced in the body from dietary linoleic acid through the delta-6-desaturase enzyme. This conversion step is consistently impaired by aging, elevated cortisol, insulin resistance, alcohol, and hormonal changes meaning many adults cannot produce adequate GLA from diet alone. Evening primrose oil delivers GLA directly from the seed, bypassing this enzymatic bottleneck entirely.

Evening primrose oil GLA is the precursor to prostaglandin E1 (PGE1), which regulates estrogen sensitive tissue, luteal phase symptoms, vascular tone, and inflammatory signalling. It is most commonly used for hormonal balance and PMS support, skin hydration and barrier repair, perimenopause and menopause support, and as a natural anti-inflammatory pathway supplement. GLA is incorporated into membrane phospholipids and ceramides that control transepidermal water loss supporting skin hydration from within.

GLA from evening primrose oil is elongated to dihomo gamma linolenic acid (DGLA), which is the direct substrate for prostaglandin E1 (PGE1) via cyclooxygenase-1. PGE1 regulates estrogen sensitive tissue responses and luteal phase symptoms associated with PMS including breast tenderness, mood changes, and cramping. Because DGLA is preferentially channelled toward PGE1 rather than pro inflammatory arachidonic acid, GLA supplementation produces a net anti-inflammatory and hormone modulating effect.

Yes. GLA from evening primrose oil is incorporated into membrane phospholipids and ceramides The structural lipids that form the skin barrier and control transepidermal water loss (TEWL). When GLA is deficient, the skin barrier becomes compromised, leading to dryness, sensitivity, and impaired repair. Supplementing with GLA supports skin hydration, barrier integrity, and inflammatory skin conditions from within.

Conventional seed oil production uses hexane solvent at elevated temperatures. This process oxidizes GLA, destroys tocopherols (vitamin E), and may leave trace solvent residues in the finished oil. Cold pressing applies mechanical pressure at low temperatures with no heat and no chemicals retaining the native fatty acid profile, antioxidant content, and phytosterol fraction of the seed.

Do not use if you have a seizure disorder or are taking phenothiazine medications evening primrose oil may lower the seizure threshold in susceptible individuals. Consult a healthcare practitioner before use if you are pregnant, breastfeeding, have a diagnosed health condition, or are taking prescription medications including anticoagulants. Stop use and consult a healthcare practitioner if headache, nausea, or loose stools occur. Ask a healthcare practitioner for use beyond 12 weeks. Keep out of reach of children.
