Key Benefits
-
1000mg organic cold pressed evening primrose oil per softgel Mechanical cold pressing retains the full fatty acid profile without heat degradation
-
100mg GLA per softgel, guaranteed 200mg GLA per daily dose of 2 softgels
-
Hormonal balance and PMS support GLA is the precursor to prostaglandin E1, which regulates estrogen-sensitive tissue and luteal phase symptoms
-
Skin hydration and barrier repair GLA is incorporated into membrane phospholipids and ceramides that control transepidermal water loss
-
Natural anti-inflammatory pathway GLA converts to DGLA, which is channelled to prostaglandin E1 rather than pro-inflammatory arachidonic acid
-
Perimenopause and menopause support Prostaglandin E1 is involved in thermoregulation and mood signalling during hormonal transition
-
Certified organic and solvent free No pesticide residues, no hexane, non-GMO
-
Health Canada licensed NPN 80141539
-
Made in Canada GMP certified facility

What This Is
A single ingredient, cold pressed evening primrose seed oil supplement in a bovine gelatin softgel.
Each softgel contains 1000mg of certified organic Oenothera biennis seed oil with a fully disclosed fatty acid profile: 100mg GLA, approximately 720mg linoleic acid, and approximately 80mg oleic acid.
The bovine gelatin shell is oxygen-impermeable, protecting GLA from oxidative degradation throughout shelf life. Contains bovine gelatin. Not suitable for vegans or vegetarians.
Licensed by Health Canada under NPN 80141539. Manufactured in Canada to GMP standards.
The Science
Why the Body Cannot Always Make Enough GLA from Diet Alone
GLA is produced from dietary linoleic acid through the delta-6-desaturase enzyme. This step is consistently impaired by aging, elevated cortisol, insulin resistance, alcohol, and hormonal changes.
When delta-6-desaturase is underperforming, linoleic acid accumulates without converting to GLA. Evening primrose oil delivers GLA directly, bypassing this enzymatic bottleneck entirely.
The GLA to Prostaglandin E1 Pathway
Absorbed GLA is elongated to dihomo-gamma-linolenic acid (DGLA). DGLA is the direct substrate for prostaglandin E1 (PGE1) via cyclooxygenase-1.
PGE1 is a vasodilatory, platelet-inhibiting, and anti-inflammatory eicosanoid that regulates vascular tone, immune signalling, and reproductive tissue responses. Because DGLA is preferentially channelled toward PGE1 rather than pro-inflammatory arachidonic acid, GLA supplementation produces a net anti-inflammatory effect.
Cold Pressing Versus Solvent Extraction
Conventional seed oil production uses hexane at elevated temperatures. This oxidizes GLA, destroys tocopherols, and may leave trace solvent residues.
Cold pressing applies mechanical pressure at low temperatures with no heat and no chemicals. The result is a complete oil that retains its native fatty acid profile, antioxidant content, and phytosterol fraction.
Why Organic Source Matters for a Fatty Acid Supplement
GLA and linoleic acid are lipophilic and readily accumulate fat-soluble contaminants including organochlorine pesticides. Certified organic seed eliminates this pathway entirely.
Standardized to 100mg GLA per Softgel
Evening primrose oil naturally contains 8 to 10% GLA, but this varies with seed genetics and harvest conditions. A non-standardized 1000mg softgel may deliver as little as 80mg GLA.
This formulation guarantees a minimum of 100mg GLA per softgel across every batch.

How to Use
Adults: Take 2 softgels, 1 time per day, with a meal containing dietary fat.
Dietary fat stimulates bile secretion, which is required for emulsification and lymphatic absorption of the oil. Ask a healthcare practitioner for use beyond 12 weeks.
Safety and Cautions
Do not use if you have a seizure disorder or are taking phenothiazine medications.
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.
Store in a cool, dry place away from direct light and heat. Keep bottle tightly sealed. Do not use if the seal is broken or missing. Keep out of reach of children.
