Osterly Market Evening Primrose Oil

Cold-pressed. GLA content stated.

Cold-pressed evening primrose oil with the gamma-linolenic acid content on the panel — which is the only number in this product that means anything.

What it's for

Evening primrose oil is taken for its gamma-linolenic acid, an omega-6 fatty acid the body converts into anti-inflammatory signalling molecules. It is most commonly used for cyclical breast tenderness and skin comfort. The evidence is modest and the effect, where present, is slow.

How to take it

• One softgel daily with food
• GLA is fat-soluble; take it with a meal
• Expect to give it two to three months before judging it
• Mild blood-thinning activity — mention it before surgery, and check first if you take anticoagulants or have a seizure disorder

On the label

• Cold-pressed, not solvent-extracted
• GLA content stated, not just total oil weight
• 120 softgels

What this is not

• Not a hormone treatment
• Not solvent-extracted
• Not always in stock — low-volume supplier

The straight answer

Total oil weight is the number most primrose labels print. GLA is the active. A 1000 mg softgel at 8% GLA and one at 10% are not the same product.
