What Is Evening Primrose Oil?
Evening Primrose Oil is a botanical seed oil derived from Oenothera biennis seeds and commonly sourced for its gamma-linolenic acid (GLA) content.

In B2B supplement sourcing, it is commonly supplied as cold-pressed oil, refined oil, organic oil, softgel-grade oil, microencapsulated powder or custom oil blend. Buyers usually evaluate Evening Primrose Oil by GLA percentage, linoleic acid content, oleic acid content, full fatty acid profile, peroxide value, anisidine value, acid value, TOTOX, free fatty acids, heavy metals, microbiology, odor, color, packaging, storage condition and destination market label requirements.
