Evening Primrose Oil — standardised for gamma-linolenic acid (GLA). One of the richest plant sources of GLA, widely used in hormonal balance supplements, eczema treatments, PMS relief, and premium anti-ageing skin formulations.
Evening Primrose Oil (Oenothera biennis) is one of the most clinically researched functional botanical oils — its primary bioactive, gamma-linolenic acid (GLA), has documented activity in hormonal balance, inflammatory skin conditions, PMS symptom management, and cardiovascular health. GLA is an Omega-6 fatty acid rarely present in significant amounts in common dietary fats, making evening primrose oil one of the most important dietary supplements for GLA supplementation.
SV Botanica supplies Evening Primrose Oil standardised for GLA content (8–12%) per lot — the key specification that distinguishes therapeutic-grade supply from commodity oil. Nutraceutical softgel fill grade, cosmetic topical grade, and organic COSMOS grade all available. GLA content is GC-verified with every commercial shipment.
GLA supports prostaglandin synthesis pathways clinically linked to PMS symptom relief, menstrual pain management, and menopausal symptom support.
Clinically studied for eczema — GLA deficiency is linked to atopic skin conditions. Both topical and oral supplementation have documented evidence.
GLA supports skin barrier integrity and moisture retention — particularly effective for dry, ageing, and menopausal skin experiencing reduced natural oil production.
Oral GLA supplementation associated with improved lipid profiles and reduced inflammatory markers in cardiovascular health studies.
Evening primrose oil's therapeutic value is driven primarily by its GLA content — one of the richest common plant sources of this critical Omega-6 fatty acid:
| Linoleic Acid (C18:2) | 65–80% — dominant Omega-6, skin barrier |
| Gamma-Linolenic Acid (GLA) | 8–12% — primary bioactive; hormonal, anti-inflammatory, eczema |
| Oleic Acid (C18:1) | 5–10% — minor emollient component |
| Palmitic Acid (C16:0) | 5–8% — saturated emollient |
| Stearic Acid (C18:0) | 1–3% — minor saturated FA |
| Tocopherols | ~500 mg/kg — critical antioxidant for this highly unstable oil |
| Polyphenols | Present in unrefined grade — antioxidant support |
Evening primrose oil is valued primarily for its GLA content — compare it to other GLA-containing carrier oils:
| Oil | GLA Content | Skin Feel | Best Known For |
| Evening Primrose ★ | 8–12% GLA | Light to medium | Hormonal, eczema, PMS, anti-ageing |
| Borage Oil | 20–25% GLA | Medium | Highest natural GLA — anti-ageing |
| Black Currant Seed | 14–20% GLA | Medium | GLA + ALA — anti-inflammatory |
| Hemp Seed Oil | 2–4% GLA | Light | Full omega-3/6/9 spectrum |
| Rosehip Seed | <1% GLA | Dry, light | Retinoids, carotenoids, anti-ageing |
Evening primrose oil has very high PUFA content and oxidises rapidly — always: (1) add 0.2–0.5% Vitamin E, (2) store refrigerated, (3) verify GLA content specification by GC before purchase. For supplement use: insist on GLA-standardised softgel fill grade. For cosmetic use: dilute to 5–20% in a more stable carrier (argan, jojoba). Nitrogen-flushed packaging strongly recommended.
Evening primrose oil's fatty acid profile is dominated by linoleic acid with GLA as the critical therapeutic minor component:
Beyond the fatty acids, key cosmetic actives in the unsaponifiable fraction:
| GLA (gamma-linolenic acid) | 8–12% — standardised per lot by GC; primary bioactive |
| Tocopherols | ~500 mg/kg — critical for oxidative stability of this high-PUFA oil |
| Polyphenols | Present in cold-pressed grade — antioxidant contribution |
| Phytosterols | Anti-inflammatory, skin barrier support |

This is a highly unstable oil — GLA oxidises rapidly. Always: (1) add 0.2–0.5% Vitamin E, (2) store refrigerated, (3) specify GLA content on PO. Combine with stable carrier oils (argan, jojoba) to extend formulation shelf life. Nitrogen-flushed packaging is strongly recommended for all orders.
Rosehip Seed Oil is supplied in dark-glass or HDPE packaging to protect against oxidation. Nitrogen-flushed packaging available for premium unrefined grades.
10ml–100ml amber glass vials for evaluation and stability testing.
Amber HDPE or dark glass containers with tamper-evident caps.
Food/cosmetic grade HDPE drums with tamper-evident seals. Standard commercial pack.
Intermediate bulk containers for large commercial orders.
Store in cool (below 20°C), dark conditions away from direct sunlight and heat sources. Keep containers sealed — rosehip seed oil oxidises rapidly on exposure to air. Nitrogen blanket packing available on request to maximise shelf life. Recommended shelf life: 12–18 months from date of manufacture when stored correctly.
Minimum Order Quantity
