Blackcurrant seed oil is a rich source of gamma linolenic acid (GLA), the immediate biological precursor to DGLA (dihomo gamma-linolenic acid), which bypasses the need for enzymatic conversion (delta-6 desaturase). DGLA is the substrate for the production of PGE1 series of prostaglandins. • Blackcurrant seed oil supplies a blend of GLA, linoleic (omega-6), and alpha-linolenic (omega-3) fatty acids, in combination with other essential fatty acids. • GLA is a precursor to the PGE1 series of prostaglandins, which are involved in supporting healthy eicosanoid activity. • Omega-6 and omega-3 fatty acids are essential to health, supporting healthy skin, cardiovascular health, mental health, hormone balance, joint mobility, and cell membrane fluidity.
