Project Information @ a Glance
  • Lutein is a dietary carotenoid that is present in most fruits and vegetables as well as human plasma, breast milk, organs, tissues, and ocular tissues
  • Lutein used in dietary supplements and the food industry is commercially derived from the dried petals of marigold flowers, the most abundant source of lutein in nature
  • Lutein is the primary carotenoid in the macula (the central area of the eye’s retina). Clinical studies have shown that lutein may protect the macula from potentially damaging forms of light and thus may slow or stop the progress of Age-Related Macular Degeneration
  • About 80% of the content that is found in marigolds is lutein and 5% is zeaxanthin
  • Marigold flowers (Tagetes erecta) are grown, harvested, dried, and then pellets are manufactured from the dried flower petals .
  • The marigold extract is heated to increase flowability and then purified by a patented process.
  • This process removes the fatty acids commonly found in marigold extract and produces crystalline lutein and zeaxanthin.
