2026-04-22

What is Black Currant Extract?

Black currant (Ribes nigrum) extract is derived from the deep purple berries of the black currant bush, native to Europe and Asia. Exceptionally rich in anthocyanins, vitamin C, and gamma-linolenic acid (GLA), black currant extract is valued for its powerful antioxidant properties and support for eye health, immune function, and overall wellness.

Key Benefits

  • Eye & Vision Health: Rich in anthocyanins, particularly delphinidin and cyanidin, that may help support healthy vision and reduce eye fatigue.

  • Immune Support: Exceptionally high in vitamin C and antioxidants that help support the body's natural immune defenses.

  • Anti-inflammatory Properties: Contains GLA and anthocyanins that may help reduce inflammation and support joint health.

  • Circulatory Health: May help support healthy blood vessel function and microcirculation through its rich polyphenol content.

  • Antioxidant Protection: One of the highest ORAC values among berries, providing powerful protection against oxidative stress.
