Jarrow Formulas Evening Primrose 60 Softgels

Primrose is a solvent-free cold pressed oil from evening primrose seeds (Oenothera biennis), a superior source of gamma-linolenic acid (GLA). 

GLA is an important omega-6 fatty acid that is needed for the production of beneficial prostaglandins (hormone-type compounds), which play an important role in promoting immune regulation.
