Definition
  • Zeaxanthin is a naturally occurring xanthophyll pigment, it is an oxygenated carotenoid. Synthetic zeaxanthin is produced by a multi-step chemical synthesis from smaller molecules.

    Synthetic zeaxanthin is presented either as a spray-dried powder of gelatin or starch base (‘beadlets’) with added α-tocopherol and ascorbyl palmitate or as a corn oil suspension with added α-tocopherol
