Description

Evening Primrose Oil is a premium botanical oil extracted from the seeds of the *Oenothera biennis* plant, valued for its high concentration of γ-linolenic acid (GLA), an essential ω-6 fatty acid. This natural ingredient is crucial for formulating high-quality nutraceutical, cosmetic, and pharmaceutical products due to its well-documented bioactive properties. It is primarily sought by manufacturers in the dietary supplement, personal care, and functional food industries seeking a reliable, pure source of GLA.

Quality Control

Our Evening Primrose Oil is produced and tested to meet stringent quality standards suitable for human consumption and sensitive applications. We ensure compliance with relevant guidelines for botanical extracts. Certificates of Analysis (COA) documenting key parameters such as GLA content, peroxide value, and heavy metals are available upon request to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at temperatures between 15-25°C (59-77°F). Due to its polyunsaturated nature, it is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in bulk to maximize shelf life and prevent rancidity. Keep away from heat and open flames.
