Evening Primrose Oil

Evening primrose oil is primarily known as a source of the omega-6 fatty acid GLA (gamma-linolenic acid). The oil is extracted from the seeds of the Oenothera biennis.

Evening Primrose Oil - Additional Information

In the Netherlands, we have known evening primrose oil for many years from the brand Efamol, which stands for Essential Fatty Acid MOLecule, but also from products such as Solgar's Evening Primrose Oil. Although initially all GLA supplements were based on evening primrose oil, in recent years, more and more manufacturers have switched to using borage oil (Borago officinalis) as a raw material. This oil contains a much higher percentage of GLA, allowing for more cost-effective production of the capsules. Therefore, evening primrose oil and borage oil can be used for exactly the same purposes.
