Zeinoxanthin is a rare carotenoid with antioxidant properties, commonly found in foods like oranges and also present in the tissues of the human eye.

The word "zeinoxanthin" comes from the Greek words "zeinos", which means "grain", and "xanthus", which means "yellow". The name indicates the presence of this pigment in plants such as corn, in which it can be found.

The compound is closely associated with zeaxanthin and shares comparable antioxidant benefits, playing a role in supporting eye health and shielding against oxidative damage.
